Mental Health Act 1983

In certain circumstances you can be made to go to hospital under a section of the Mental Health Act, even if you don't want to. There are many terms you might hear used to describe this, including:

• Compulsory admission to hospital
• Detention or involuntary detention
• Being a formal patient
• Being sectioned

Before you can be lawfully sectioned, you'll need to be assessed by a team of health professionals, to make sure that it's necessary.

To find out more about when it may be legal to section you, what different sections mean and what your rights are in hospital, see our legal pages on sectioning.

If you're in hospital as an informal patient (also known as voluntary patient), you're free to leave the hospital or ward should you choose. But if your care team is worried about you, they can detain you temporarily so that a decision can be made about whether you should be sectioned. When these powers are used:

• You're no longer free to leave and
• You'll need to stay in hospital for assessment to see if you need to be detained under section 2 or section 3

Before you can be lawfully sectioned, you'll need to be assessed by a team of health professionals, to make sure that it's necessary. To find out more see our legal pages on voluntary patients.

Yes, the police may be involved if:

• You are suspected of committing an offence, or
• They need to take you to a place of safety under sections 135 or 136

To find out more about when and how the police can become involved in each of these instances, see our legal pages on the police and mental health and sectioning.

If you are going to the criminal court to be tried for committing a crime and the court receives reports from a health professional that you're unwell enough, it can order you to be detained in hospital:

• While you're awaiting trial, and/or
• As part of your sentence

To find out more about what sections apply here and how this process works, see our legal pages on the courts and mental health and sectioning.

A medical professional should always seek your informed consent before giving you treatment for your physical or mental health.

But the Mental Health Act says that in some circumstances, you can receive treatment from medical professionals for your mental disorder without your consent. This can happen when you are detained under certain sections of the Act.

The Mental Health Act only authorises treatment for mental disorder, so you couldn't be given treatment without your consent for a physical illness under the Act, unless the physical problem is a symptom or cause of a mental disorder.

To find out more about when it's legal to treat you against your wishes, see our legal pages on consent to treatment.

Your family members may have certain legal rights related to your sectioning. For example, your family member might be your nearest relative. Your nearest relative has certain rights and responsibilities, including a right to:

• Apply for you to be sectioned
• Receive information about your sectioning
• Discharge you if you're sectioned and apply to the Mental Health Tribunal if this is refused
• Object to your sectioning

To find out more about who can be your nearest relative and what they are able to do for you, see our legal pages on the nearest relative.

In England and Wales, if you're in hospital because you've been sectioned you have the right to get support from an advocate called an Independent Mental Health Advocate (IMHA). In Wales, you also have the right to get support from an advocate if you're in hospital as a voluntary patient and haven't been sectioned.

An IMHA can help you do a range of things, including:

• Explain your rights and help you exercise them
• Express your views
• Make a complaint
• Apply to a Mental Health Tribunal
• Access legal advice

To find out more about what an IMHA can do for you and how to get one, and for information on advocacy more generally, see our legal pages on IMHAs (England) and IMHAs (Wales).

If you're detained in hospital you're sometimes able to leave for a short period of time, even if you're still under section. This is called section 17 leave.

To find out more about taking short periods of leave from hospital while under section, see our information on leaving the ward.

If you've been sectioned, the Mental Health Act gives you the right to be given information on ways in which your section can end. This may also be called being 'discharged' from your section. You can still stay in hospital even if your section has ended. This is called being an informal patient.

If you want to be discharged and you're under sections 2 or 3, you can:

• Ask your responsible clinician to discharge you
• Ask for a meeting with the hospital managers and ask them to discharge you
• Ask your nearest relative to discharge you
• Apply to the Mental Health Tribunal to be discharged

When the hospital discharges you they may put you onto a community treatment order (CTO). This means you won't have to stay in hospital but there might be some conditions to this. For example, you may have to live in a certain place or go somewhere specific for medical treatment.

To find out more about being discharged from hospital, see our legal pages on:

• Leaving hospital
• Discharge FAQs
• Nearest relatives' rights
• Community treatment orders (CTOs)

You may have a right to free aftercare under section 117 of the Mental Health Act after you've left hospital.

This is the help you can get for free in the community, including healthcare, social care and supported accommodation. You can only get this if you've been on certain sections, for example section 3.

To find out more about what care you're entitled to when you leave hospital, see our legal pages on care planning and aftercare under section 117.
