Section Three of the Mental Health Act: A Patient and Family Guide
Being detained under section three of the Mental Health Act, or supporting a loved one who has been, raises urgent questions that deserve clear, accessible answers. This guide is written specifically for patients and families navigating this experience, with a focus on what it means in day-to-day practical terms.
In Plain Terms: What Does Section Three Mean?
If you or a loved one has been “sectioned under section 3,” it means a person has been legally admitted to a psychiatric hospital for treatment of a mental disorder, without their agreement, because the professionals involved believe:
- They have a mental disorder that requires hospital treatment
- Treatment cannot safely be provided unless they are in hospital
- There is a treatment available that can help them
It is not a punishment. It is not permanent. And it does not mean a person has lost their legal rights or their ability to challenge the decision.
The Difference Between Section 2 and Section 3 in Everyday Terms
Section 2 is about finding out what is wrong and what treatment might help, a period of assessment. Section 3 comes after the clinical picture is clearer, and is specifically about delivering treatment.
In practice, many people move from a Section 2 assessment period into a Section 3 treatment order if it becomes clear that their condition requires longer-term treatment that cannot be provided voluntarily. Sometimes, Section 3 is applied directly without a preceding Section 2, particularly in cases where a diagnosis is already well established.
How Long Will It Last?
Section 3 initially authorises detention for up to six months. The patient does not automatically stay for six months, many people are discharged significantly before this, either when the clinical team considers it appropriate, or when the patient successfully appeals through the Mental Health Tribunal.
After six months, the section can be renewed, first for another six months, and then for periods of one year. However, every renewal requires a clinical review to confirm the original criteria are still met.
What Treatment Can Be Given?
During the first three months of section 3, the clinical team can give medication for the mental disorder without requiring the patient’s consent. This is the aspect of section 3 that patients and families often find most difficult.
After three months, an independent psychiatrist (a Second Opinion Appointed Doctor, or SOAD, appointed by the Care Quality Commission) must review whether ongoing medication without consent is appropriate. This is an important safeguard.
Patients can and should be involved in conversations about their treatment, their preferences, and the reasons for clinical decisions, even during compulsory treatment.
What Rights Does the Person Have?
Even while detained under section 3, the patient has important rights:
The right to appeal, the Mental Health Tribunal is an independent legal body that can order a patient’s discharge. Patients can apply at any time during their section, and the Tribunal must hear from them within a reasonable period.
The right to an Independent Mental Health Advocate (IMHA), a free, independent advocate who can help the patient understand their rights, communicate with staff, and navigate the system. This service is available to all detained patients.
The right to family involvement, within the limits of confidentiality, families can be involved in care planning and are entitled to information about what is happening.
Section 117 aftercare, when the person is discharged, they are legally entitled to free aftercare services under Section 117 of the Mental Health Act. This is a right that many families are unaware of but it is extremely important, the NHS and local council must provide support services free of charge after a Section 3 discharge.
What Can Families Do?
For the nearest relative: The nearest relative (as defined by the Mental Health Act, usually but not always the closest family member) has specific legal powers, including the right to request the patient’s discharge and the right to apply independently to the Mental Health Tribunal. The nearest relative also has the right to object to the initial Section 3 application, though the AMHP can apply to court to override this if they believe the objection is unreasonable.
For all family members:
- Keep communication open with the ward team
- Ask to attend Care Programme Approach (CPA) meetings, you have the right to be involved
- Contact the hospital’s Patient Advice and Liaison Service (PALS) if you have concerns about care
- Seek independent legal advice from a mental health solicitor if you believe the detention is unlawful
Supporting Wellbeing During and After Section 3
The period of hospital detention under section 3 is often physically as well as emotionally taxing. Medication side effects, institutional environments, disrupted sleep, and the stress of the process itself all take a physiological toll. Supporting the body’s recovery alongside the psychiatric treatment is something that herbal medicine can meaningfully contribute to.
At Herba Naturalle, the Nervous System Reset Bundle is designed to support the physiological recovery of the nervous system, reducing the chronic over-activation and inner agitation that often persists after a psychiatric crisis, and supporting the body’s gradual return to balance.
Contact the clinic for a personal consultation. More information about herbal medicine is available at About Herbal Medicine.
The Herba Naturalle 3-Step Bundle
The Herba Naturalle Bundle supports recovery and long-term resilience through three physiological steps:
Step 1, Restore Digestion: Digestive health is the foundation of physical and mental recovery. The Digestive Reset Bundle begins the healing process from within.
Step 2, Calm the Surface Nervous System: The Nervous System Reset addresses the physiological agitation that persists long after a mental health crisis.
Step 3, Heal the Smooth Muscle Lining: Deep inflammation in the organ linings contributes to systemic physiological stress. The Smooth Muscle and Immune Reset Bundle addresses this at the root.
