If you lose mental capacity without a lasting power of attorney in place, your family cannot automatically make decisions for you. Instead, they must apply to the Court of Protection to be appointed as a deputy. This process can be time-consuming, costly, and may delay important decisions about your finances and care.

What Does It Mean to Lose Mental Capacity?
Losing mental capacity means you are unable to make or communicate decisions for yourself. This could be due to illness, injury, or conditions such as dementia.
Capacity can be lost suddenly or gradually. When it happens, decisions still need to be made about your finances, property, and personal welfare. Without a lasting power of attorney, there is no automatic legal authority for others to act on your behalf.
What Happens If There Is No Lasting Power of Attorney?
If no lasting power of attorney is in place, your family or loved ones must apply to the Court of Protection to gain authority to act.
The court will decide who should be appointed as a deputy. This person will then be responsible for managing your affairs under the court’s supervision.
This process can take time and may not result in the person you would have chosen being appointed.
What Is a Deputy and What Do They Do?
A deputy is someone appointed by the Court of Protection to make decisions on behalf of a person who lacks capacity.
There are two types of deputyship. One covers property and financial affairs such as managing bank accounts and paying bills. The other covers personal welfare decisions, although these are less commonly granted. Deputies must act in your best interests and follow strict legal rules.

Why Is It Less Common to Be Granted a Personal Welfare Deputyship Order?
In England and Wales, the Court of Protection is generally cautious about granting personal welfare deputyship orders. Under the Mental Capacity Act 2005, decisions about a person’s care, medical treatment, and living arrangements can usually be made on a case-by-case basis in that person’s best interests without the need for a deputy.
Unlike financial matters, welfare decisions are often highly personal and can change over time. The court therefore prefers the least restrictive approach, allowing professionals, carers, and family members to make individual best interests decisions as circumstances arise rather than giving one person ongoing authority over all welfare matters.
Personal welfare deputyships are usually only granted where there is clear evidence that continuing authority is necessary, such as ongoing disputes between family members and professionals, repeated serious medical decisions, or safeguarding concerns. Even then, the court will normally limit the deputy’s powers to specific issues rather than granting broad control over all aspects of a person’s welfare.
How Long Does the Court Process Take?
Applying for deputyship can take several months. During this time, important decisions may be delayed, particularly where access to bank accounts or property is required.
The process involves submitting detailed forms, medical evidence, and paying court fees. Ongoing supervision by the court may also apply once a deputy is appointed.
What Are the Costs Involved?
Deputyship applications involve court fees, possible legal fees, and ongoing supervision charges. In some cases, deputies may also need to obtain a security bond.
These costs are usually paid from the person’s estate but can still reduce the overall value available to beneficiaries.
When Do You Need a Lasting Power of Attorney?
A lasting power of attorney should be put in place while you still have mental capacity. Once capacity is lost, it is too late to create one.
Planning ahead allows you to choose who will manage your affairs and ensures that decisions can be made quickly if needed. Many people choose to set up an LPA alongside making a will as part of their overall planning.
Common Mistakes to Avoid
One of the most common mistakes is assuming that a spouse or close family member can automatically step in and make decisions. This is not the case without legal authority.
Another mistake is delaying the process until it is too late. Loss of capacity can happen unexpectedly, so early planning is essential. Failing to register an LPA after creating it can also cause delays when it is needed.
Frequently Asked Questions
Can my spouse automatically manage my finances if I lose capacity?
No. Your spouse or partner does not have automatic authority to manage your finances without a lasting power of attorney or court appointment.
What is the Court of Protection?
It is a court that makes decisions about people who lack mental capacity, including appointing deputies to act on their behalf.
Is deputyship the same as an LPA?
No. A deputy is appointed by the court after capacity is lost, while an LPA is chosen by you in advance.
Can I avoid the Court of Protection process?
Yes. By setting up a lasting power of attorney while you have capacity, you can avoid the need for deputyship.
