Part ofCourt of Protection UK

Updated June 2026 · England & Wales
The Court of Protection sits at the heart of decisions made for people who lack the mental capacity to make those decisions themselves. If you are supporting a relative with dementia, a loved one recovering from a brain injury, or someone with a lifelong learning disability, there is a reasonable chance you will come across the COP family of forms at some point. The paperwork can feel intimidating, particularly when several forms look similar and each one plays a slightly different role in the process. This guide walks through the main Court of Protection forms in plain English, explains when each is typically used, and flags some of the points that commonly trip people up. It is written for family members, carers, and anyone thinking about applying to become a deputy or make a one-off application to the court. I'm Brad Askew, Legal Tech Founder at LegalDocuments.co.uk, and I've spent years helping people navigate unfamiliar legal paperwork.

What this document is

The Court of Protection is a specialist court in England and Wales that makes decisions about the property, finances, health, and welfare of adults who cannot make those decisions for themselves. Its powers come from the Mental Capacity Act 2005, which sets out how capacity is assessed and the principles that must guide any decision made on someone else's behalf.

The court also authorises deprivation of liberty where an adult is, in practical terms, not free to leave a care home or hospital because of the arrangements made for their care. COP forms are the paperwork you use to engage with this court.

Some forms start an application, such as asking to be appointed as a deputy so you can manage a relative's finances on an ongoing basis. Others provide supporting information, such as a capacity assessment completed by a doctor or other qualified professional.

A few deal with urgent situations, for example where decisions about a person's liberty need to be made quickly. Each form has a specific role, and using the right combination matters because the court will not progress an application that is incomplete.

How to use this document

  1. Work out what you are actually asking the court to do. Before touching any forms, be clear on whether you need ongoing authority to make decisions (a deputyship), a one-off decision on a specific issue, or something urgent relating to care arrangements. The type of application drives which COP forms you will need, so getting this right at the start saves considerable time later. 2. Gather the core application pack. For most deputyship applications this means Form COP1 as the main application, together with the relevant annex (COP1A for property and finances, COP1B for personal welfare, COP1C for a narrower financial matter, or COP1D for trustee appointments). You will usually also need COP1E to provide supporting information about the person concerned and the decisions that need to be made. 3. Arrange a capacity assessment using Form COP3. This form is completed by a suitable professional, often a GP, psychiatrist, social worker, or specialist nurse, who confirms whether the person can make the decisions in question. Without a properly completed COP3, the court has no independent evidence that the Mental Capacity Act threshold has been met, and your application is unlikely to proceed. 4. Complete your deputy's declaration on Form COP4. If you are asking to be appointed as deputy, COP4 is where you set out information about yourself, confirm you understand the responsibilities involved, and declare that you are suitable for the role. The court takes this declaration seriously because deputies hold significant power over another person's life, so fill it out carefully and truthfully. 5. Notify the right people and file the application. The rules require you to notify the person the application is about, and often close family members, that an application has been made. Forms such as COP5 are used by those who want to take part in the proceedings. Once the paperwork is complete, the application is sent to the court with any required fee (check gov.uk for the current amount).

Common questions

Q What is the difference between COP1A, COP1B, COP1C and COP1D?
These are all annexes to the main COP1 application form, and each one covers a different type of decision. COP1A is used when you are asking for authority over property and financial affairs. COP1B deals with personal welfare decisions, such as where someone lives or medical treatment. COP1C covers a narrower financial issue rather than full deputyship, and COP1D is used specifically when appointing or discharging a trustee.
Q Who can complete a COP3 capacity assessment?
The COP3 form is completed by a professional who is qualified to assess mental capacity for the specific decision in question. In practice this is often a general practitioner, a psychiatrist, a registered social worker, a psychologist, or a specialist nurse who knows the person well. Some professionals charge a fee for completing the form. The assessor must apply the test set out in the Mental Capacity Act 2005.
Q Do I need a solicitor to make a Court of Protection application?
You do not have to use a solicitor for most Court of Protection applications, and many family members complete the forms themselves, particularly for straightforward property and finance deputyships. That said, contested applications, complex family circumstances, or welfare disputes can become difficult quickly, and professional help is often worth considering in those cases. Weigh up the complexity against your confidence with paperwork.
Q What are the COP DLA, DLB, DLD and DLE forms for?
These forms deal with deprivation of liberty applications, which arise where a person who lacks capacity is, in practical terms, not free to leave their care setting. COP DLA starts an application for urgent consideration, COP DLB is a declaration of exceptional urgency, COP DLD handles service and notification certificates, and COP DLE is the acknowledgment used by those served with or notified of the application.
Q When would I use Form COP7 or COP8?
COP7 is used to object to the registration of a Lasting Power of Attorney, for example where there are concerns about how the LPA was made or about the proposed attorney. COP8 relates to the registration of an Enduring Power of Attorney, which is the older style of power of attorney that could only be created before October 2007. Existing EPAs can still be registered and used.
Q Is there a court fee for Court of Protection applications?
Yes, the Court of Protection charges fees for applications, and further fees may apply for hearings. Some applicants qualify for fee remission based on their income and savings, and in some cases fees are paid from the assets of the person the application is about. Fees change periodically, so check gov.uk for the current amounts before sending your application.
Q How long does a Court of Protection deputyship application take?
Timescales vary depending on how busy the court is, whether the application is contested, and how complete the paperwork is when submitted. Straightforward property and finance deputyships often take several months from start to finish. Applications with missing forms, unclear information, or objections from family members can take considerably longer, which is why getting the paperwork right first time is worthwhile.
