COP3 Assessment What Social Workers Really Look For

If you’ve been told you need a COP3 assessment, you’re probably feeling a bit overwhelmed. The form itself looks daunting, the legal language is dense, and you might be wondering what actually happens during the assessment itself.

I’ve completed hundreds of COP3 assessments over the years. In my experience, families and solicitors get better results when they understand what the assessment is really looking for, not just what the form says. So let me explain it in plain terms.

What Is a COP3 Assessment?

A COP3 assessment is a structured Mental Capacity Act assessment that focuses on a specific decision. It applies what’s called the “four abilities test” and records clear evidence for the Court of Protection.

The core question is straightforward: can the person make the particular decision the court is being asked to make? This might be managing money, selling a property, or agreeing to care arrangements.

As the assessor, I need to decide two things:

1. Is there an impairment of the mind or brain?
2. Because of that impairment, is the person unable to understand, retain, use or weigh, or communicate about the relevant information for that decision?

Good preparation matters. When I arrive with the right decision clearly defined, the right information prepared, and communication support in place, the assessment is fair, person centred, and unlikely to be questioned by the judge.

The Legal Framework (In English)

Under the Mental Capacity Act 2005, a person lacks capacity if, at the material time, they are unable to make a specific decision because of an impairment of, or disturbance in, the functioning of the mind or brain.

Section 3 of the Act sets out the four abilities test. The person must be able to:

• Understand the information relevant to the decision
• Retain that information long enough to make the decision
• Use or weigh that information as part of the decision-making process
• Communicate their decision (by any means)

And critically, all practicable support must be provided first.

COP3 is the court’s standard form for capacity evidence. It must be filed with most deputyship and other applications under Practice Direction 9A.

What I Actually Check During the Assessment

I start by confirming the exact decision (or decisions) in Part A. For example:

• Managing property and finances
• Deciding where to live
• Consenting to care arrangements

Then I check for a diagnostic cause. This might be dementia, brain injury, learning disability, or severe mental illness. I need to establish that there is an impairment affecting the person’s ability to decide.

Next, I test each of the four abilities in relation to the “relevant information” for that specific decision. I record:

• How the person presented
• What was explained
• What questions were asked
• How the person responded
• Any fluctuations in capacity
• Whether capacity might improve

All of this goes into the structured Part B of the COP3 form.

Applying the Four Abilities Test in Practice

During the assessment, here’s what I’m actually doing:

Understanding

I explain the decision in clear terms. For example, “selling your house to pay for care” or “appointing a deputy to manage your money”. Then I check whether the person can describe that information back in their own words.

Retention

I check whether the person can hold the main points in mind long enough to make a decision. This might only be for a short period, and that’s fine. The question is whether they can retain it long enough to weigh it up.

Use or Weigh

I ask the person to compare options, think about risks, benefits, and consequences, and show some reasoning. This reasoning can be simple. It can even lead to an “unwise” choice. What matters is that they’re engaging with the information and thinking it through.

Communication

I confirm the person can communicate their decision by any method. This includes speech, writing, gestures, or assistive technology. I record what works and what doesn’t.

If the person cannot do one or more of these steps because of the impairment, I explain how that difficulty showed itself in practice. I then link it back to the impairment. This is called the “causative nexus”, and it’s essential for a robust assessment.

Communication and Support

Before concluding that someone lacks capacity, I must show that “all practicable steps” were taken to support decision making. This is in line with section 1 of the MCA 2005.

In practice, this usually includes:

• Choosing the best time of day
• Using plain language
• Breaking information into small chunks
• Using visual prompts or written summaries
• Involving a familiar supporter if the person wishes
• Allowing extra time or breaks

Where communication is impaired, I may use communication aids, interpreters, or specialist techniques. I record what was tried and how well it worked. The court needs to see that lack of capacity is not being assumed just because communication is difficult.

What the Court Expects to See

A robust COP3 assessment provides clear, decision specific examples. It shows how the person responded to real questions about their money, property, care, or legal arrangements.

The form asks for:

• The impairment or diagnosis
• Whether capacity is fluctuating or likely to improve
• What support was used
• What further steps might help
• Whether more than one decision is being assessed (for example, both property and affairs, and health and welfare)

I also set out my qualifications and experience under the MCA, explain whether the assessment was done in person or remotely, and sign a statement of truth. This confirms that my opinion is independent and evidence based.

Why Preparation Matters for Families

Families and solicitors can make the assessment smoother and more accurate by preparing Part A carefully. Define each decision in one clear sentence. Explain why the court needs to deal with it now.

Practical preparation includes:

• Gathering key documents (such as bank statements, care home information, sale particulars)
• Choosing a quiet, familiar environment at the person’s best time of day
• Planning any communication support
• Explaining in advance, in simple terms, that someone is visiting to talk through important decisions

Good preparation reduces distress for the person, helps me apply the test properly, and lowers the risk of the court asking for further evidence and delaying the application.

The Independent Angle

An independent social worker like me is not tied to local authority thresholds, internal policies, or resource pressures. I can focus solely on the MCA test, the person, and the question the court needs answered.

I offer detailed, legally literate COP3 assessments that clearly link real life evidence to sections 2 and 3 of the MCA. I explain the communication and support used, and I produce reports designed to withstand scrutiny from judges and opposing parties.

For families and professional deputies, this can mean fewer adjournments, clearer best interests decisions, and more confidence that the court has the evidence it needs.
