What Is a COP3 Form?
Whats on this page
If a Court of Protection application is being made and there is a question about whether someone can make a particular decision for themselves, one of the most important documents in the process is often the COP3 form. A COP3 is the official Court of Protection form used to give formal evidence about mental capacity. It is not a general opinion and it is not an informal note. It is a structured legal form that must address a specific decision, apply the Mental Capacity Act 2005 test and explain how the conclusion has been reached.
What the COP3 form is actually used for
The COP3 is used to provide the Court of Protection with formal evidence about whether a person has capacity to make the relevant decision or decisions themselves. In many cases it sits at the centre of the application because the court needs more than a diagnosis or a general impression. It needs reasoned evidence tied to the actual issue before it.
When a COP3 form is usually needed
A COP3 is usually needed when Court of Protection proceedings are being started and evidence of capacity is required as part of the application. It is especially common in deputyship cases, but it can also be used in other Court of Protection matters where the court needs a clear view on capacity in relation to a particular issue.
Why a COP3 must be decision-specific
A COP3 is about capacity for a specific decision at a specific time. It is not a general verdict on whether someone has capacity overall. A person may be able to make some decisions but not others, which is why the form asks what decision or decisions need to be made and allows more than one to be listed separately.
What information needs to be covered in a COP3 assessment
A proper COP3 should identify the relevant information for the decision in question. That usually means setting out what the decision is, why it needs to be made, what options exist and what the reasonably foreseeable consequences are of deciding one way or another or not deciding at all. If more than one decision is being assessed, the relevant information may differ for each one.
How capacity is assessed on a COP3
The COP3 follows the Mental Capacity Act 2005 framework. The assessor considers whether the person can understand the relevant information, retain it, use and weigh it and communicate a decision by any means. If the person cannot do one or more of those things, the assessor must then explain whether that is because of an impairment of, or disturbance in the functioning of, the mind or brain.
The role of support and practicable steps
The law does not allow a person to be treated as unable to make a decision unless all practicable steps have been taken to support them without success. The COP3 reflects that principle by asking what support may help the person make their own decision and what support was actually provided during the assessment.
Who can complete a COP3 form
The form says that Part B must be completed by an appropriate assessor. It gives medical practitioners and social care professionals as examples, but the key point is not job title alone. What matters is whether the assessor has the qualifications, training, practical experience and independence needed to assess capacity properly and explain their reasoning clearly.
Common problems with COP3 forms
Weak COP3s often use vague wording, fail to identify the relevant information, give conclusions without analysis under the four functional elements or rely too heavily on diagnosis instead of explaining the link between impairment and inability to decide. Those weaknesses can lead to questions, delay or requests for further evidence.
What happens after a COP3 is completed
Once the COP3 has been completed, the assessor usually returns it to the applicant or the applicant’s solicitor. It is then filed with the court as part of the wider application or proceedings. The court reviews it alongside the other material in the case and uses it to help decide whether the person lacks capacity in relation to the relevant matter and what order, if any, should be made.
Frequently asked questions
Is a COP3 form the same as a general mental capacity assessment?
No. A COP3 is a Court of Protection form used to provide evidence about capacity in relation to a specific decision or set of decisions. It is more structured and more decision-focused than a general assessment note.
Can one COP3 cover more than one decision?
Yes. The form allows more than one decision to be listed, but each decision should be identified clearly and the relevant information should be addressed properly where needed.
Does a completed COP3 automatically mean the court will appoint a deputy?
No. The COP3 is important evidence, but the court still has to consider the wider application, the order sought and whether the legal requirements for that order have been met.
