Capacity and Consent


In this chapter, guidance is offered in relation to the various situations in which consent is likely to be sought, with reference to previous legal judgements, including:

  • Legal capacity in relation to parents/those with Parental Responsibility;
  • Legal capacity in relation to children/young people;
  • Looked after children/young people;
  • NICE quality Standard: Decision Making and Mental Capacity.

This is a potentially complex practice arena and if the practitioner is in any doubt about gaining consent they should always seek further advice from managers and legal advice must be sought as necessary.

There are links throughout this chapter to additional relevant sections within the Social Work Procedures Manual.

This chapter was added to the Manual in March 2023.

1. Introduction

Professionals should always seek consent from children, young people, parents and carers, whether adult or child/young person, to a particular decision or course of action. This raises the issue of Capacity to agree a course of action or make the decision in question which must also be considered. Issues of Capacity and Consent may arise in various contexts. It may be necessary to consider the legal Capacity of parents and/or children/young people to make decisions and give valid, informed consent.

Legal Capacity can fluctuate and, for consent to be valid, it must be made by a person who has the legal Capacity to make that decision at that time, having a clear, fully informed understanding of what it is they are consenting to. This will include the likely outcomes which may flow from the consent being given.

Issues of Capacity and Consent may arise, for example, in relation to:

  • Assessments and Early Help interventions;
  • Information sharing;
  • Legal proceedings, e.g., where a Gillick/Fraser competent child/young person desires separate legal representation and/or their wishes differ from the views of the child/young person's Guardian;
  • Parent's capacity to instruct solicitors and participate in court proceedings; Working with parents with learning disabilities/mental health problems/challenges;
  • Children/young people becoming looked after, e.g., parental agreement to children/young people being accommodated under section 20 of the Children Act 1989;
  • Delegation of authority to carers in respect of day-to-day matters;
  • Consent in relation to health assessments and medical treatment;
  • Parental consent to adoption or a Special Guardianship Order;
  • Deprivation of liberty of a child/young person.

For consent to be valid, it must be given voluntarily by an appropriately informed person who has the capacity to consent to the particular intervention in question at that particular time.

Once it has been determined that a person has the capacity to make a particular decision at a particular time, a further requirement (under the common law) for that consent to be valid is that it must be given voluntarily and freely, without pressure or undue influence being exerted upon them.

Acquiescence where the person does not fully understand what they are being asked to agree to is not 'consent'.

In situations where a parent/carer may decline to consent to a Child & Family Assessment, consent should be sought in stages. For example, obtaining consent to a home visit, then obtaining consent for information sharing, and then obtaining consent for the Child & Family Assessment to be undertaken - working towards securing full consent and working collaboratively with children/young people and their families.

Consent should be periodically requested especially when further decisions and actions are being considered.

2.1 Consent to Information Sharing

Under the UK General Data Protection Regulation (UK GDPR), there must always be a lawful basis for sharing of personal information relating to children and families. The clear consent of the data subject is one of the available legal bases under which information can be shared - but there are five others, and it is important to always choose the lawful basis that most closely reflects the true nature of your relationship with the individual and the purpose of the processing / sharing.

The UK GDPR sets a high standard for consent to share information, and requires that it must be specific, time limited and able to be withdrawn.

Consent in this context would mean that children and families are offered real choice and control about whether their information will be shared or not.

It is not necessary therefore to seek consent to share information for the purposes of safeguarding and promoting the welfare of a child/young person, providing there is another lawful basis for the sharing.

The statutory guidance Working Together to Safeguard Children (DfE) states:

You do not need consent to share personal information. It is one way to comply with the data protection legislation, but not the only way. The GDPR provides a number of bases for sharing personal information. It is not necessary to seek consent to share information for the purposes of safeguarding and promoting the welfare of a child/young person provided that there is a lawful basis to process any personal information required.

The legal bases that may be appropriate for sharing data in these circumstances could be 'legal obligation' or 'public task' which includes performance of a task in the public interest or the exercise of official authority. Each of the legal bases under GDPR has different requirements.

3.1 Capacity in Relation to Adults

The Mental Capacity Act 2005 defines a person who lacks capacity as a person who is unable to make a decision for themselves because of an impairment or disturbance in the functioning of their mind or brain. It does not matter if the impairment or disturbance is permanent or temporary. A person lacks capacity if:

  • They have an impairment or disturbance (for example a disability, condition or trauma or the effect of drugs or alcohol) that affects the way their mind or brain works; and
  • That impairment or disturbance means that they are unable to make a specific decision at the time it needs to be made.

An assessment of a person's capacity must be based on their ability to make a specific decision at the time it needs to be made, and not their ability to make decisions in general. A person is unable to make a decision if they cannot do one or more of the following things:

  • Understand the information given to them that is relevant to the decision;
  • Retain that information long enough to be able to make the decision;
  • Use or weigh up the information as part of the decision-making process and communicate their decision – this could be by talking or using sign language and includes simple muscle movements such as blinking an eye or squeezing a hand.

People may have capacity to consent to some interventions but not to others or may have capacity at some times but not others. Under the Mental Capacity Act, a person must be assumed to have capacity unless it is established that they lack capacity.

A person's capacity to consent may be temporarily affected by factors such as confusion, panic, shock, fatigue, pain or medication. However, the existence of such factors should not lead to an automatic assumption that the person does not have the capacity to consent.

Capacity should not be confused with a practitioner's assessment of the reasonableness of the person's decision. Under the Mental Capacity Act and the common law, a person is not to be treated as unable to make a decision merely because they make an unwise decision. A person is entitled to make a decision which may be perceived by others to be unwise or irrational, as long as they have the capacity to do so.

However, if the decision that appears irrational is based on a misperception of reality, as opposed to a different value system to that of the practitioner – for example a person with anorexia nervosa who is unable to comprehend their failing physical condition – then the person may not be able to comprehend, weigh up or make use of the relevant information and hence may lack the capacity to make the decision in question.

The Mental Capacity Act also requires that all practical and appropriate steps are taken to enable a person to make the decision themselves. These steps include the following:

  • Providing relevant information. For example, if there is a choice, has information been given on the alternatives?
  • Communicating in an appropriate way. For example, could the information be explained or presented in a way that is easier for the person to understand?
  • Making the person feel at ease. For example, are there particular times of the day when a person's understanding is better?
  • Supporting the person. For example, can anyone else help or support the person to understand information and to make a choice?

A mental capacity assessment must be carried out when:

  1. There are indicators that the person may not be able to make the decision at the time that it needs to be made; and
  2. There is evidence that the person has (or may have) an impairment of, or disturbance in the functioning of the mind or brain; and
  3. The reason that the person may not be able to make the decision is related to (or may be related to) the impairment in, or disturbance of the functioning of the mind or brain.

3.2 Parents with a Learning Disability

A learning disability is a permanent life-long condition, which is defined by the Department of Health as:

  • A significantly reduced ability to understand new or complex information, to learn new skills (impaired intelligence);
  • A reduced ability to cope independently (impaired social functioning), which started before adulthood, with a lasting effect on development.

However, many people who have a diagnosed learning disability prefer to use the term 'learning difficulty'. They feel that the term 'learning disability' implies that they cannot learn at all.

There is a far wider group of parents with learning difficulties, who do not have a diagnosis and would not generally fit the eligibility criteria for support services in their own right.

Historically IQ testing was used as an assessment method in an attempt to categorise degrees of learning disability, however, modern assessments use a broader approach to assess strengths and needs and should be part of a person-centred approach to care and support planning, leading to a person-centred plan describing what is important to and important for the individual to live a good life with as much choice and control as possible.

The case of A Local Authority v G (Parent with Learning Disability) [2017] EWFC B94 identified five key features of good practice in working with parents with learning disabilities:

  • Accessible information and communication;
  • Clear and co-ordinated referral and assessment procedures and processes, eligibility criteria and care pathways;
  • Support designed to meet the needs of parents and the child/young person based on assessments of their needs and strengths;
  • Long-term support where necessary;
  • Access to independent advocacy.

The case also highlighted the need for specialist:

Training - specialist training on working with parents with a learning disability, emphasising how best to work with the parents and how to deliver the right support.

Accessible information and communication:

Communication - communicating with parents in a way they understand.

This may include:

  • Taking more time to explain things;
  • Telling parents things more than once and checking their understanding of what has been said;
  • Considering in advance how best to prepare for meetings, and discussing with parents whether they would like an Advocate to support them to prepare for the meeting and take part in it;
  • Hands-on approaches, such as role-play, modelling, and filming tasks being completed;
  • Step by step pictures showing how to undertake a task;
  • Repeating tasks regularly and providing opportunities for frequent practice;
  • Use of 'props', for example, containers which will hold the right amount of milk.

Parents should be told, in plain language, what any assessment is, what it is for, what it will involve, and what will happen afterwards. They may need to be told more than once, for example, a parent may need to be reminded what happened at the last meeting.

3.3 Parents with Mental Health Problems

Mental health problems are proportionately common in the overall population. The term does not in itself have one clear definition, and therefore the existence of mental health problems should not be taken as a risk factor without contextual information.

The state of a person's mental health is usually not static and can vary according to several factors, correspondingly their capacity to parent safely may also be variable, and therefore, an understanding of the factors which may increase risk is an important part of any assessment.

For further information, see: 

3.4 Section 20 Accommodation - Obtaining Parental Consent

The Supreme Court in Williams and another (Appellants) v London Borough of Hackney (Respondent) [2018] UKSC 37 confirmed that 'Consent' under any of the Section 20 provisions was not a statutory requirement as such. It stated that the Local Authority has a duty to provide accommodation for children/young people (subject to a parent being able to legally object and / or remove) where the person who had been caring for them was 'prevented (whether or not permanently and for whatever reason) from providing them with suitable accommodation or care'.

This, therefore, supports the Local Authority in its duties towards children/young people on those occasions where 'parental consent' cannot, for a variety of reasons, be obtained at the time of a child/young person's accommodation or parents cannot affect care of the child/young person themselves.

Nevertheless, with regard to previous court judgments on 'consent', it reflected that they were, 'in short, good practice guidance and a description of the process that the family court expects to be followed'.

Therefore, obtaining parental consent as a matter of good practice remains an essential part of accommodating a child/young person under this part of the Children Act 1989 (2004). A number of court decisions have been particularly critical of local authorities' actions with regard to consent and great care needs to be undertaken to ensure parents have the appropriate capacity to do this.

Section 20 agreements are not valid unless the parent giving consent has capacity to do so (in cases where the father also has Parental Responsibility, the consent of both parents should be sought). The consent needs to be properly informed and fairly obtained. Willingness to consent cannot be inferred from silence, submission or acquiescence - it is a positive action.

Detailed guidance on the obtaining of parental consent was given by the High Court in the case of Re CA (A Baby) (2012):

  • The social worker must first be satisfied that the parent giving consent does not lack the mental Capacity to do so. Under the Mental Capacity Act 2005, a person is unable to make a decision if they are unable:
    • To understand the information relevant to the decision;
    • To retain that information;
    • To use or weigh up that information as part of the process of making the decision; or
    • To communicate their decision.

The High Court in Re S (Child as parent: Adoption: Consent) [2017] EWHC 2729 (Fam) set out the relevant information that a parent would need to be able to understand, retain and weigh up in order to have competency to consent to the accommodation of a child/young person:

  • That the child/young person will be staying with someone chosen by the Local Authority, probably a foster carer;
  • That the parent can change their mind about the arrangements, and request the child/young person back from accommodation at any time;
  • That the parent will be able to see the child/young person;
  • If there is doubt about Capacity, no further attempts to obtain consent should be made at that time, and advice should be sought from a manager;
  • If satisfied that the parent has Capacity, the social worker must be satisfied that the consent is fully informed:
    • Does the parent fully understand the consequences of giving such consent?
    • Does the parent fully appreciate the range of choice available and the consequences of refusal as well as giving consent?
    • Is the parent in possession of all the facts and issues material to the giving of consent and can this be demonstrated?
  • If not satisfied that the consent is fully informed, no further attempt should be made to obtain consent on that occasion and advice should be sought from a manager and legal advice sought if thought necessary;
  • If satisfied that the consent is fully informed, then it is necessary to be satisfied that the giving of such consent and the subsequent removal of the child/young person from the parent is both fair and proportionate:
    • What is the current physical and psychological state of the parent?
    • If they have a solicitor, have they been encouraged to seek legal advice and/or advice from family or friends?
    • Is it necessary for the safety of the child/young person for them to be removed at this time?
    • Would it be fairer in this case for this matter to be the subject of a court order rather than an agreement?

Whether a person has capacity can sometimes be difficult to determine, as some individuals have a learning disability or mental health problem but can present as being more 'able' than in fact they are. Equally, within the context of 'assessing capacity', social workers should approach with great care relying on Section 20 agreements from mothers after giving birth (especially where there is no immediate danger to the child/young person and where, in all probability, no order would be made).

Where there is any concern about a parent/carer's capacity, the social worker should ensure they discuss this issue with their team manager, or that the parent has information from a legal adviser or professional advice. Note: In Coventry City Council v C, B, CA and CH (2012) EWHC2190 (Fam) it was identified that, 'every social worker obtaining consent is under a personal duty (the outcome of which may not be dictated to by others) to be satisfied that the person giving consent does not lack the capacity to do so'.

Note that the High Court in Re S (Child/young person as parent: Adoption: Consent) made clear that parental Capacity to consent to a child/young person being accommodated under s.20 Children Act 1989, does not equate to their capacity to consent to an adoption order in respect of the child/young person - the capacity to consent is decision-specific.

Recording Parental Consent

In Re N (Children) (Adoption: Jurisdiction) [2015] EWCA Civ 1112 the (then) President of the Family Division, Sir James Munby sets out his view in respect of good practice in the recording of parental consent to a Section 20 agreement:

  • Wherever possible the agreement of a parent to the accommodation of their child/young person under Section 20 should be properly recorded in writing and evidenced by the parent's signature;
  • The written document should be clear and precise as to its terms, drafted in simple and straight-forward language that the particular parent can readily understand;
  • The written document should spell out, following the language of section 20(8), that the parent can 'remove the child/young person' from the LA accommodation 'at any time';
  • The written document should not seek to impose any fetters on the exercise of the parent's right under s.20(8). Where the parent is not fluent in English, the written document should be translated into the parent's own language and the parent should sign the foreign language text, adding, in the parent's language, words to the effect that 'I have read this document and I agree to its terms';
  • This should then be uploaded to Livelink under 'essential information'.

3.5 Consent to Adoption

See Relinquished Children Procedure (where parents are requesting that their child/young person be placed for adoption).

4.1 Age 16 Years and Above - Mental Capacity Act 2005

The Mental Capacity Act 2005 provides a statutory framework for people who lack capacity to make decisions for themselves. The accompanying Code of Practice provides guidance to anyone who is working with and/or caring for people who may lack capacity to make particular decisions.

A person's capacity (or lack of capacity) refers specifically to their capacity to make a particular decision at the time it needs to be made and the lack of capacity to make a decision is caused by an impairment or disturbance that affects how the mind or brain works.

From the age of 16 years, the Mental Capacity Act 2005 applies. Everyone working with (or caring for) any young person from the age of 16 who may lack capacity must comply with the Mental Capacity Act and its associated Code of Practice.

The Mental Capacity Act applies whenever:

  • There are doubts over the ability of a young person (from the age of 16) to make a particular decision at a particular time; and
  • The young person has an impairment of, or a disturbance in the functioning of the mind or brain.

Section 3 of the Mental Capacity Act says that a young person (from the age of 16) is able to make their own decision if they can do all of the following four things:

  1. Understand information given to them;
  2. Retain that information long enough to be able to make the decision;
  3. Weigh up the information available to make the decision; and
  4. Communicate their decision.

For further information, see: Mental Capacity Procedure.

4.2 Below 16 Years - Gillick Competence

Children and young people below the age of 16 years may be Gillick Competent to give consent.

  • The determination of a child/young person's competence must be decision-specific and child/young person-specific;
  • Just because the child/young person lacks competence in one context does not mean they lack it in another;
  • The assessment of competence must be made on the current evidence;
  • The child/young person should be of sufficient intelligence and maturity to:
    1. Understand the nature and implications of the decision and the process of implementing that decision;
    2. Understand the implications of not pursuing the decision;
    3. Retain the information long enough for the decision-making process to take place;
    4. Weigh up the information and arrive at a decision;
    5. Communicate that decision.

Note: Gillick competence is concerned with determining a child/young person's capacity to consent.

Fraser guidelines are used specifically to decide if a child/young person (under 16) can consent to contraceptive or sexual health advice and treatment.

Practitioners using the Fraser guidelines should be satisfied of the following:

  • The child/ young person cannot be persuaded to inform their parents or carers that they are seeking this advice or treatment (or to allow the practitioner to inform their parents or carers);
  • The child/young person understands the advice being given;
  • The child/young person's physical or mental health or both are likely to suffer unless they receive the advice or treatment;
  • It is in the child/young person's best interests to receive the advice, treatment or both without their parents' or carers' consent;
  • The child/young person is very likely to continue having sexual intercourse with or without contraceptive treatment.

4.3 Consent to the Use of Medication to Suppress Puberty

The Court of Appeal in Bell and A –v- Tavistock and Portman NHS Trust and Others [2021] EWCA Civ 1363 held that, in relation to the use of medication to suppress puberty, the child/young person under 16 can consent provided that their treating clinician considers them to be competent to do so in accordance with the usual Gillick competency principles. (This reversed a High Court judgement which had held that it was highly unlikely that a child/young person under 13 could give informed consent to the treatment, and very doubtful that a child/young person aged 14 or 15 could).

Clinicians will need to ensure that the consent obtained from both the child/young person and their parents is properly informed by the advantages and disadvantages of the proposed course of treatment and in the light of evolving research and understanding of the implications and long-term consequences of such treatment.

The Court of Appeal recognised that applications to the court may well be appropriate in specific difficult cases but held that it was not appropriate to give guidance as to when such circumstances might arise.

5. Looked After Children/Young People

5.1 Delegation of Authority to Carers

Decisions about the care of a Looked After child/young person are likely to fall into three broad areas:

  • Day-to-day parenting, e.g., routine decisions about health/hygiene, education, leisure activities;
  • Routine but longer term decisions, e.g., school choice;
  • Significant events, e.g., surgery.


  • Authority for day-to-day decision making about a Looked After child/young person should be delegated to the child/young person's carer(s), unless there is a valid reason not to do so*;
  • A Looked After child/young person's Placement Plan should record who has the authority to take particular decisions about the child/young person. It should also record the reasons where any day-to-day decision is not delegated to the child/young person's carer;
  • Decisions about delegation of authority should take account of the Looked After child/young person's views, and consideration should be given as to whether a Looked After child/young person is of sufficient age and understanding to take some decisions themselves.
  • 'The carer' means the foster carer or registered manager of the child/young person's home where the child/young person resides.

5.2 Consent to Health Care Assessments

A valid consent will be necessary for a Health Care Assessment. Who is able to give this consent will depend on the age and understanding of the child/young person. In the case of a very young child, the Local Authority as corporate parent can give the consent. An older child/young person with mental capacity may be able to give their own consent.

Young people aged 16 or 17

Young people aged 16 or 17 with mental capacity are presumed to be capable of giving (or withholding) consent to their own medical assessment/treatment, provided the consent is given voluntarily and they are appropriately informed regarding the particular intervention. If the young person is capable of giving valid consent, then it is not legally necessary to obtain consent from a person with Parental Responsibility.

Child/young person under 16 – 'Gillick Competent'

A child/young person of under 16 may be Gillick Competent to give (or withhold) consent to medical assessment and treatment, i.e., they have sufficient understanding to enable them to understand fully what is involved in a proposed medical intervention.

In some cases, for example because of a mental disorder, a child/young person's mental state may fluctuate significantly, so that on some occasions the child/young person appears Gillick Competent in respect of a particular decision and on other occasions does not.

If the child/young person is Gillick Competent and is able to give voluntary consent after receiving appropriate information, that consent will be valid, and additional consent by a person with Parental Responsibility will not be required.

Child/young person under 16 - Not 'Gillick' Competent

Where a child/young person under the age of 16 lacks capacity to consent (i.e., is not Gillick Competent), consent can be given on their behalf by any one person with Parental Responsibility. Consent given by one person with Parental Responsibility is valid, even if another person with Parental Responsibility withholds consent. (However, legal advice may be necessary in such cases). Where the Local Authority, as corporate parent, is giving consent, the ability to give that consent may be delegated to a carer (foster carer or registered manager of the child/young person's home where the child/young person resides) as a part of 'day-to-day parenting', which will be documented in the child/young person's Placement Plan.

For further information, see:

5.3 Deprivation of Liberty (DoL) of a Child/Young Person

Local authorities need to consider whether any children in need or looked-after child/young person (especially those in foster care or in a residential placement), are subject to restrictions which amount to a Deprivation of Liberty and, if so, how this is to be authorised.

There is an option on LCS for a case status to be added re. Deprivation of Liberty (DoL) and all children/young people subject to a DoL order need to have this case status added to their own individual case record. This must be added at the point of when the order is granted and removed once the order expires.

For further information, see: 

5.4 Consent to Life-Ending Withdrawal of Medical Support

This is only applicable to children/young people in Local Authority Care (CLA) under section 31.

The High Court in Herefordshire Council –v- M and F and others (Re YY (Children: Conduct of the Local Authority) stated that the making of a decision which is likely to result in the death of a looked after child/young person (such as the withdrawal of life support treatment) comes within a small category of cases where, notwithstanding the Local Authority's powers to exercise corporate parental responsibility under section 33(3)(b) Children Act 1989, the consequences of the exercise of that particular act of parental responsibility are so profound and have such an impact on the child/young person, and/or the Article 8 rights of other parties who share parental responsibility, that the matter must come before the High Court for its consideration and determination.

In such cases, therefore, urgent legal advice must be sought, even if all parties are in agreement that medical treatment should be withdrawn.

6. NICE Quality Standard: Decision-Making and Mental Capacity

NICE Quality Standard: Decision-Making and Mental Capacity, is a Quality Standard published by the National Institute for Health and Care Excellence (NICE) covering decision making in people aged 16 and over, using health and social care services, who may lack capacity to make their own decisions (now or in the future). It aims to support implementation of the aims and principles of the Mental Capacity Act 2005 and relevant Codes of Practice. It is not a substitute for these.

The Quality Standard is based around four 'Quality Statements':

  • Statement 1 - People aged 16 and over who may lack capacity to make decisions are supported with decision making in a way that reflects their individual circumstances and meets their particular needs;
  • Statement 2 - People aged 16 and over at risk of losing capacity to make decisions, and those with fluctuating capacity, are given the opportunity to discuss advance care planning at each health and social care review;
  • Statement 3 - People aged 16 and over who are assessed as lacking capacity to make a particular decision at the time that decision needs to be made, have a clear record of the reasons why they lack capacity and the practicable steps taken to support them;
  • Statement 4 - People aged 16 and over who lack capacity to make a particular decision at the time that decision needs to be made have their wishes, feelings, values and beliefs accounted for in best interests decisions.

Against each Quality Statement are a set of Quality Measures which are designed to enable measurement of whether the Statements are being met, as well as an indication of what the Statement means for different audiences, including the relevant individuals themselves.
