Common reasons COP3 forms are rejected or questioned
A COP3 may need clarification where it addresses the wrong decisions, omits support or reasoning, or no longer reflects the person’s circumstances. Read the court’s actual request before commissioning replacement evidence; not every question requires a new assessment.

04Abstract
A COP3 may need clarification where it addresses the wrong decisions, omits support or reasoning, or no longer reflects the person’s circumstances. Read the court’s actual request before commissioning replacement evidence; not every question requires a new assessment. This guide covers the relevant evidence, support, process and limits in England and Wales.
A COP3 may need clarification where it addresses the wrong decisions, omits support or reasoning, or no longer reflects the person’s circumstances. Read the court’s actual request before commissioning replacement evidence; not every question requires a new assessment.
06The wrong decision was assessed
COP3 must identify the decisions in the application and address each one. A description such as confusion, dementia or needing help does not by itself show inability to make those decisions. Check that the numbering and reasoning correspond with Part A.
07Diagnosis substituted for functional analysis
A diagnosis may help explain the concern but cannot substitute for evidence of the decision-making abilities. The form asks about understanding, retention, use or weighing and communication, with an explanation for each answer. Missing reasoning may call for clarification; the court decides what additional evidence is needed.
08Explain how impairment causes any inability
If an inability is found, explain why an impairment of, or disturbance in the functioning of, the mind or brain causes it. Identifying a condition and a difficulty separately does not show the link. A reasoned explanation supports scrutiny without guaranteeing that the evidence will be accepted.
09The assessment is stale
COP3 asks for current information. Its adequacy depends on the relevant decision, any changes and the court’s directions, rather than a universal expiry date. Ask the assessor whether an update or new assessment is needed if circumstances have materially changed.
10No evidence of practicable steps
The Act requires that all practicable steps are taken to help the person decide before they are treated as unable to do so, and the court expects to see them. Forms are questioned where there is no record of how the assessment was adapted: whether the person was seen at their best time of day, whether information was simplified and broken down, whether communication aids or an interpreter were used, and whether a second visit was offered where presentation fluctuated. One line stating that support was provided is assertion, not evidence.
11Internal inconsistency and contradiction with other evidence
Different abilities can coexist: fluent speech or independence in daily life does not establish capacity for every financial or welfare decision. Explain apparently inconsistent evidence and whether it concerns the same decision, support and time. Correct factual mistakes and address genuinely contrary findings.
12Doubts about the assessor
The assessor should explain their qualifications, training, experience, relationship with the person and freedom from conflict. A treating relationship does not automatically disqualify them, and external instruction does not automatically establish independence. The issue is suitability and the quality of the evidence for this question.
13How to avoid a rejected or questioned COP3
Before filing, check the decisions, relevant information, support, findings, causal explanation, dates and signature. Provide relevant records and disclose gaps. If the court asks questions, respond to the directions through the appropriate person rather than assuming the entire assessment must be replaced.
14Key takeaway
A complete, current and decision-specific COP3 helps the court understand the evidence. It supplies an opinion; the court decides capacity, the need for further evidence and whether an order should be made.
15Frequently asked questions
Does a diagnosis automatically mean someone lacks capacity?
No. A diagnosis does not establish lack of capacity. For a decision under the Mental Capacity Act, consider the relevant information and practicable support, then assess understanding, retention, use or weighing and communication by any means. Any inability must be caused by an impairment of, or disturbance in the functioning of, the mind or brain. Will-making has its own legal test.
What evidence is useful for COP3 Mental Capacity Assessment?
Keep the letter of instruction, the records reviewed, the assessor's notes and the reasoning behind each conclusion. When a COP3 is questioned, the fastest resolution is usually a prompt, well-evidenced response from the original assessor, which is only possible where the underlying file is complete.
When is a formal assessment for COP3 Mental Capacity Assessment useful?
Read the court’s concerns first. A correction, explanation or focused update from the original assessor may suffice; a new assessment is appropriate where the evidence or circumstances require it. Seek advice on the directions and time for responding.

Read the court’s request and identify whether it concerns an omission, a factual error, reasoning or changed circumstances. Ask the assessor to address that issue, and obtain advice before replacing the form or assuming the application has failed.
