Sectioning
Explains your rights if you're sectioned and detained in hospital under the Mental Health Act 1983.
Being sectioned
When you're sectioned, it means you'll be kept in hospital to get mental health treatment and support, even if you don't agree to this. Sectioning is used to keep you safe, as well as to keep other people safe.
You might feel confused, upset or angry about being sectioned. You're not alone, and our information is here to help you.

What is being sectioned?
Being sectioned means you're kept in hospital under a set of laws called the Mental Health Act 1983. The Act is written out as different ‘sections’ for different situations. This is why we call it ‘being sectioned’.
Each different type of section has its own rules about keeping you in hospital. The length of time that you'll stay in hospital depends on which section you're detained under.
After you've been sectioned, what might happen during your stay in hospital will depend on:
- Which section you're detained under
- Your specific mental health problem
- Your need for care and treatment
- Your personal circumstances
When can I be sectioned?
You can be sectioned when someone has raised concerns about your mental health. For example, if a family member or a social worker contacts your local authority.
Usually, doctors will only section you if everything else they've tried hasn't worked. For example, they might've asked you to agree to go into hospital informally. To find out more, see our information on informal patients.
Doctors should only consider sectioning you if you meet all 3 of the following criteria:
- You need to go into hospital for doctors to assess or treat your mental health problem.
- Your safety, or someone else's safety, would be at risk if doctors did not assess or treat you.
- It's not possible to assess or treat you outside of hospital.
Before you can be sectioned, a team of health professionals will perform a Mental Health Act Assessment to decide if you need to be sectioned. For more information, see our page about being assessed.
Example: why Kenneth might need to be sectioned
Kenneth has schizophrenia and has gone into hospital many times over the last 18 years.
Recently, he's been acting irrationally and out of character. He seems unable to look after himself. It turns out that he hasn't taken his medication for months.
Kenneth seems to have lost a lot of weight, but when someone offers him food, he gets annoyed. He keeps saying, “I told you, I'm not hungry”, then pushes it away.
He's become forgetful and doesn't seem aware of everyday dangers anymore. He's wandered on to a busy road a few times in recent weeks.
His wife thinks that he might need urgent medical treatment in hospital. Without this, she thinks his health and safety might be at risk. She reports this to their local authority.
What do the different sections mean?
There are different types of sections. Each has different rules to keep you and other people safe.
The sections you'll probably hear about most are section 2, section 3, section 5(2) and section 5(4).
What is section 2?
You can be detained under section 2 if you meet all 3 of the following criteria:
- You have a mental disorder.
- You need to be detained for a short time for assessment and possibly medical treatment.
- Detaining you is necessary for your own health or safety, or to protect other people.
You can be detained for up to 28 days under section 2. Normally, this section can't be extended or renewed. But doctors might assess you again before the end of the 28 days to see if you should be put under section 3.
What is section 3?
You can be detained under section 3 if you meet all 4 of the following criteria:
- You have a mental disorder.
- You need to be detained for your own health or safety, or to protect other people.
- Health professionals would not be able to give you treatment unless you're detained in hospital.
- Doctors agree that appropriate treatment is available for you in hospital.
You can be detained for up to 6 months under section 3. After 6 months, your responsible clinician (RC) can renew or extend your section 3 in different ways:
- The first extension can last up to 6 months more.
- The second extension can last up to another 6 months.
- After this, each further extension can last up to 12 months each time.
There's no limit to how many times your RC can renew a section 3. But they can also discharge you from hospital before your section 3 comes to an end.
If your mental health gets worse again in the future, you could be sectioned again.
What is section 5(2)?
Section 5(2) only applies if you're an informal patient staying in hospital already. You could be in hospital for physical or mental health treatment.
A section 5(2) means you must continue to stay in hospital while doctors decide whether to put you on a section 2 or section 3. You might also hear this called a ‘detention section’ or a ‘holding power’.
You can be detained for up to 72 hours under section 5(2). You cannot challenge this section at the Mental Health Tribunal.
What is section 5(4)?
Section 5(4) applies to informal patients receiving treatment for a mental disorder in hospital.
A nurse who is specially trained to work with mental health problems or learning disabilities can keep you in hospital under section 5(4).
They can do this if they think that your mental health problem is serious enough to meet both of these conditions:
- You need to be kept in hospital immediately for your health or safety, or for the protection of others.
- It's not practical to get a health practitioner or clinician to provide a report to the hospital managers.
This nurse can detain you for up to 6 hours under section 5(4). Within this time, a doctor should assess you. The doctor might detain you under a longer section following your assessment.
You can be detained under section 4 if you meet all 3 of the following criteria:
- You have a mental disorder.
- It's ‘urgently necessary’ for you to be admitted to hospital and detained.
- If you waited for a second doctor to confirm that you need to go into hospital under section 2, this wait would cause ‘undesirable delay’.
Rather than the team of 3 health professionals who normally do a Mental Health Act Assessment, just 1 doctor and the AMHP can detain you under section 4. They can take you to hospital in an emergency and assess you there.
You can be detained for up to 72 hours under section 4. Your rights are different compared to your rights under other sections. For example, doctors cannot treat you without your consent under section 4.
You'll usually hear section 7 called ‘guardianship’.
You can only be placed under guardianship if it's necessary for your welfare, or to protect other people. It gives someone called a ‘guardian’ the power to make certain decisions about you. They can also make conditions that you'll be asked to follow, like where you'll live.
You can live in the community under guardianship instead of being detained in hospital. Guardianship aims to let you live with some independence outside of hospital.
Under section 7, your guardian is appointed by law. Your guardian could be a person, like a nearest relative, or a local authority.
Guardianship can last up to 6 months. It can be extended for another 6 months, then each further extension can last a year at a time. During each of these periods, you can only challenge this section once at the Mental Health Tribunal.
Section 17 only applies if you're already detained under another section of the Mental Health Act.
Section 17 gives the responsible clinician power to ‘grant you leave’ for a set period of time. Having ‘leave’ means being able to spend time outside of the ward or hospital.
They'll probably ask you to follow certain conditions, such as:
- Returning to hospital on a certain day or time
- Staying at a particular place
- Spending your time on leave under the care of a particular person
These sections deal with the nearest relative:
- Section 26 sets out who your nearest relative should be.
- Section 29 explains how and why you might want to change your nearest relative to a different person.
To find out more, see our information on nearest relatives and changing your nearest relative.
Section 35 applies if you've been accused of a crime in criminal proceedings. The Crown Court or Magistrates' Court can remand you to hospital if at least 1 doctor has evidence of both of the following:
- There's ‘reason to suspect’ that you have a mental disorder.
- If you were remanded on bail, it would be difficult to make a report on your mental condition.
They might want to remand you to hospital to have more time to assess you and make their report. This report might help determine whether you're unfit to plead.
You can be kept under section 35 for up to 28 days. It can be extended for further periods of 28 days, up to a maximum of 12 weeks total.
To find out more, see our information on the courts and mental health.
Under section 37, you can be sent to hospital for treatment. You might also hear it called a ‘hospital order’. There are 2 different courts that can put you under this section:
- The Crown Court can make a hospital order before or after you've been convicted of an offence.
- The Magistrates' Court can only make a hospital order after you've been convicted of an offence that could be punished with a prison sentence.
A court can make a hospital order if 2 doctors have evidence for these 3 conditions:
- You have a mental disorder of a nature or degree that makes it appropriate to detain you for medical treatment.
- There is appropriate medical treatment available for you.
- A hospital order is the most suitable option for you.
To make this decision, they must consider all ‘relevant circumstances’ that might be available to the court. This includes your past history, your character, and other methods of managing or treating your mental health problem.
You can be kept under section 37 for up to 6 months. It can be extended by a further 6 months, and then for 1 year at a time.
To find out more, see our information on the courts and mental health.
If the Crown Court has made a hospital order under section 37, it can also set a ‘restriction order’ called section 41. This means that you'll need permission from the Ministry of Justice to be discharged, transferred or given section 17 leave.
The court will make a restriction order if it's necessary to protect the public from serious harm.
There is no fixed time limit for how long you can be kept under section 41. This section can also change the time limit of section 37.
To find out more, see our information on the courts and mental health.
If the Ministry of Justice orders you to be transferred from prison to hospital for mental health treatment, you might be put under section 47.
You can be kept under section 47 for up to 6 months. It can be extended for another 6 months, and then further extensions of 1 year at a time.
To find out more, see our information on the courts and mental health.
If you're transferred from prison to hospital under section 47, the Ministry of Justice can also put you under section 49 at the same time. You might hear this called a ‘restriction direction’.
This means that the Secretary of State for Justice must give permission to discharge, transfer or grant you leave from hospital.
You can be kept in hospital under section 49 until the end of your related section 47. Or you can be kept up until the date when you should be released from prison.
To find out more, see our information on the courts and mental health.
Under section 117, health authorities and local social services have a duty to provide free aftercare. They should offer this when you've been discharged from hospital.
Their duty to provide aftercare applies if you meet any of these conditions:
- You've been discharged under section 3, 37, 45A, 47 or 48.
- You've been given section 17 leave.
- You've been put on a community treatment order (CTO).
The free aftercare services they provide must meet both of these conditions:
- The services meet a need relating to your mental health problem.
- The services should prevent your mental health from getting worse, to the point that you'd need to return to hospital.
For more information, see our page on section 117 aftercare.
You might be put under section 135 if there's ‘reasonable cause to suspect’ that you have a mental disorder. You must also meet either 1 of these conditions:
- You're being ill-treated, neglected or not kept under proper control.
- You live alone and are unable to care for yourself.
Section 135 might also involve the police. A magistrate can allow a police officer – along with a doctor and an AMHP – to enter any place where they believe you are. They can then keep you there or take you to a place of safety.
You can be kept under section 135 for up to 24 hours. In some cases, this can be extended up to 36 hours.
To find out more, see our information on police and mental health, and sections 135 and 136.
A police officer can take you to, or keep you at, a place of safety under section 136. They can do this if they believe that you have a mental disorder and are ‘in need of immediate care or control’.
In the place of safety, a doctor will examine you and an AMHP will interview you. After this, they'll make any necessary plans for your treatment or care.
You can be kept under section 136 for up to 24 hours. In some cases, this can be extended up to 36 hours.
To find out more, see our information on police and mental health, and sections 135 and 136.
Place of safety
This is a locally agreed place where the police may take you to be assessed. It's usually a hospital but can be your home. A police station should only be used in an emergency.

Guardianship
This is where someone called a 'guardian' is appointed instead of you being sectioned and kept in hospital. Your guardian could be a person or a local authority.
You can only be placed under guardianship if it's necessary for your welfare or to protect other people. Your guardian has the power to make certain decisions about you. They can also make conditions that you'll be asked to keep to. For example, where you live.

This is the mental health professional in charge of your care and treatment while you're sectioned under the Mental Health Act.
Certain decisions can only be taken by the responsible clinician. For example, applying for someone who is sectioned to go onto a community treatment order (CTO).
All responsible clinicians must be approved clinicians. They don't have to be doctors, but many of them are.

Nearest relative
The nearest relative is a family member. They have certain responsibilities and powers if you are detained in hospital under the Mental Health Act. These include the right to information and to discharge in some situations.
The law sets out a list to decide who will be your nearest relative. This can sometimes be changed.
See our pages on the nearest relative for more information.
Visit our full listing of Legal TermsCommunity treatment order (CTO)
If you've been sectioned and treated in hospital, your responsible clinician can put you on a CTO.
This means that they can discharge you from the section and you can leave hospital. But you might have to meet certain conditions. For example:
- Living in a certain place
- Going somewhere for medical treatment
Sometimes you could be made to go back to hospital. For example:
- If you don't follow the conditions
- If you become unwell again
See our pages on CTOs for more information.
Visit our full listing of Legal TermsNot kept under proper control
A not kept under proper control warrant is issued under the Mental Health Act. It means you're vulnerable because of your mental health problem. And that you need a level of care or control to keep you safe and healthy that you're not receiving at that time.
Visit our full listing of Legal TermsApproved mental health professional (AMHP)
AMHPs are mental health professionals who can carry out duties under the Mental Health Act. They've been approved by a local social services authority. They're responsible for coordinating your assessment and admission to hospital if you're sectioned.
They may be:
- Social workers
- Nurses
- Occupational therapists
- Psychologists
Voluntary patient
Voluntary patients are people who are staying in a psychiatric hospital but are not detained under the Mental Health Act. They're also known as 'informal patients'.
If you're a voluntary patient, you should be able to come and go from the hospital within reason. And you should be able to discharge yourself if you decide to go home.
See our pages on informal patients for more information.
