A CoP3 is the official form used by the Court of Protection to record an assessment of a person’s mental capacity. It’s usually needed when someone applies to make decisions on behalf of another person who may lack capacity, for example to become their Deputy or make a specific decision about property, finance or welfare.

You’ll need a CoP3 when you’re applying to the Court of Protection to make decisions for someone who may not be able to do so themselves.

This might include:

• Family members or friends applying to be a Deputy

• Solicitors and case managers supporting clients

• Local authority or care professionals preparing applications

Only an approved assessor, such as a specialist mental capacity expert, can complete the CoP3.

At CoP3 Online, all assessments are carried out by independent, experienced professionals whose reports are accepted by the Court of Protection and High Court.

You’ll usually need a CoP3 before you can submit an application to the Court of Protection.

The form confirms that the individual has been properly assessed under the Mental Capacity Act (2005) and whether they have, or lack, the capacity to make the specific decision in question.

An online CoP3 assessment is suitable when the person being assessed:

• Has access to a video-enabled device

• Can participate in a short video assessment

• Is in a safe, quiet, private setting

• 
  

If not, a face-to-face assessment may be more appropriate. You can find more details or book through our partner site: TimFarmer.co.uk.

Yes, provided it’s completed by an appropriately qualified assessor and follows the requirements of the Mental Capacity Act (2005).

Usually around 45–60 minutes, depending on the person’s communication needs and the complexity of the decision being assessed.

The assessor will meet with the individual (and, if appropriate, a supporting person) via secure video call. They’ll explain the purpose of the assessment, ask clear, structured questions about the specific decision in question and record their findings carefully.

The process is designed to be calm, respectful and supportive.

It's not a 'test', but a conversation to understand the person’s capacity in that area.
