Lasting Powers of Attorney
What Happens If You Lose Capacity Without a Lasting Power of Attorney?
If you lose mental capacity without a valid Lasting Power of Attorney, your spouse, partner or children do not automatically gain unrestricted authority to manage your affairs. Ongoing financial decisions may require a Court of Protection deputyship order. Health and welfare decisions follow a different framework.

What is mental capacity?
Mental capacity means being able to make a particular decision when it needs to be made. Under the Mental Capacity Act 2005, a person is presumed to have capacity unless established otherwise. They must be given practicable support to decide, and an unwise decision alone does not show that they lack capacity.
The assessment is decision-specific and time-specific. Someone might be able to choose meals or manage small purchases but not understand a complex property transaction. Capacity can fluctuate; an assessment must not treat a diagnosis or age as an automatic answer.
The Act considers whether an impairment or disturbance in the functioning of the mind or brain means someone cannot understand relevant information, retain it long enough, use or weigh it, or communicate their decision. Where appropriate, specialist evidence can help establish capacity for the decision in question.
What does an LPA do?
A Lasting Power of Attorney lets an adult with the required capacity appoint one or more attorneys to make specified decisions. It must be registered with the Office of the Public Guardian before it can be used.
- Property and Financial Affairs LPA: covers matters such as banking, bills, investments and property. Once registered, it can be used with the donor’s permission while they have capacity, unless its terms restrict this.
- Health and Welfare LPA: covers matters such as care, residence and medical treatment. It can only be used when the donor lacks capacity for the relevant decision. Authority over life-sustaining treatment requires the appropriate express choice in the LPA.
The two forms have different functions. Read more about Lasting Powers of Attorney and the available drafting service.
Does my spouse automatically have power of attorney?
No. Marriage or civil partnership does not give one spouse general authority to manage all of the other’s financial affairs. A spouse may need an existing registered LPA, a valid relevant Enduring Power of Attorney, or an appropriate court order.
For example, a spouse cannot assume that they may operate a solely held bank account, change investments or sign for a property sale on the other person’s behalf. Joint ownership is different, but does not provide unrestricted authority over the other owner’s interests.
Can my children make decisions for me automatically?
No. Adult children do not acquire general legal authority just because they are next of kin. They may help practically and should often be consulted about welfare, but consultation is not the same as being authorised to sign documents or manage someone else’s money.
Limited arrangements may cover particular tasks. For example, a Department for Work and Pensions appointee can manage benefits for someone unable to do so; that does not make them a deputy with authority over all finances. Check the scope of any existing authority before relying on it.
What happens to bank accounts without an LPA?
For a solely held account, a bank will normally require lawful authority before allowing someone else to manage it where the customer lacks capacity. Knowing their password, holding their card or being a relative is not a substitute for that authority.
It would be misleading to say every account is automatically frozen. Banks’ responses depend on the account and circumstances. The OPG’s guidance on managing a bank account for someone else explains that joint-account use may be temporarily restricted to essential transactions when one holder loses capacity, until appropriate authority is in place.
Speak to the bank early about bills and care costs, explain the situation and ask what documents it needs. Do not assume that an ordinary third-party mandate continues after loss of capacity.
What is Court of Protection deputyship?
A deputy is someone appointed by the Court of Protection to make decisions for a person who lacks the relevant capacity. The court decides whether appointment is needed, who should act and what powers the order gives.
Property and financial affairs deputies may manage matters such as paying bills and administering money, within the order’s limits. An application involves evidence of capacity, information about the person’s affairs and the proposed deputy, and notification requirements. Appointment is not automatic simply because an applicant is a relative.
Personal welfare deputyship is treated differently and is not routinely granted for every person who lacks capacity. The court may instead decide a particular welfare issue. Its official guidance describes the more limited circumstances in which a welfare deputy is usually appointed.
How is deputyship different from an LPA?
An LPA is made by the donor while they have capacity to make it; a deputyship order is made by the court when the relevant capacity is lacking. Neither gives unlimited power.
| Question | LPA | Deputyship |
|---|---|---|
| Who chooses? | The donor chooses attorneys. | The court appoints a suitable deputy. |
| When arranged? | While the donor has capacity to make the LPA. | When the person lacks the relevant capacity. |
| Approval/process | Execution, certification and OPG registration. | Court application, capacity evidence and an order. |
| Scope and flexibility | The form, donor’s instructions and law define authority. | The court order defines powers; extra authority may require another application. |
| Supervision | Attorneys have duties; OPG can investigate concerns. | OPG supervision and reporting, as required. |
| Costs | Drafting advice and registration fees where applicable. | Court fees, possible advice costs, supervision and security arrangements. |
| Health and welfare | Separate LPA, usable only when relevant capacity is lacking. | Welfare appointment is less routine; specific court decisions may be appropriate. |
Is deputyship more expensive than an LPA?
It can be, particularly where ongoing supervision and professional work are needed. A deputyship application may involve a court application fee, a hearing fee where applicable, professional fees, an assessment fee for a new deputy and annual supervision fees. Property and financial affairs deputies generally need a security bond.
Deputies must keep records and provide reports as required by the OPG. Those continuing duties can take time as well as involve expense. Fee reductions or exemptions may be available depending on circumstances; check current official fees rather than relying on a single headline total.
How long does deputyship take?
There is no guaranteed timescale for every case. Preparing evidence, notifying people, court processing and any objections or requests for further information all affect the outcome. Families should not assume authority will be available immediately.
Urgent or emergency Court of Protection applications can sometimes address a serious matter with an unavoidable deadline. The court decides whether the requirements are met; urgency does not mean the ordinary evidence or safeguards can simply be ignored.
What happens to health and welfare decisions without an LPA?
Where the person lacks capacity for a particular welfare decision, the Mental Capacity Act’s best-interests framework applies. Healthcare professionals and others responsible for care must consider the person’s wishes, feelings, beliefs and values, involve them as far as possible and consult appropriate family or carers.
Family members have an important role, but “next of kin” is not a general legal power to consent to treatment or demand it. Equally, the absence of an LPA does not mean doctors take unrestricted control of every aspect of the person’s life.
A valid and applicable advance decision to refuse treatment may be binding. Serious disputes or decisions requiring court determination may go to the Court of Protection. Decisions should respect the person’s rights and use the least restrictive suitable option.
Can an LPA be made after someone loses capacity?
Only if they still have the capacity required to make that particular LPA. If that capacity has been lost, another person cannot simply create or sign a new LPA for them. A deputyship application or a specific court decision may instead be needed.
First check whether a valid LPA or older Enduring Power of Attorney already exists. An existing authority may offer a route, subject to its validity, registration and scope.
Can someone make an LPA after a dementia diagnosis?
Potentially, yes. A diagnosis alone does not establish lack of capacity to make an LPA. The question is whether the person understands the relevant nature and effect of the proposed appointment at the time.
Appropriate support and, where needed, professional assessment can help. Do not assume either that a diagnosis makes an LPA impossible or that a signature alone proves capacity. Pressure or coercion also needs to be considered.
Why make an LPA before it is needed?
Planning ahead allows you to choose attorneys yourself, discuss responsibilities and express appropriate preferences or instructions. It may avoid the need for a later deputyship application for matters covered by the LPA.
- Consider who is trustworthy, willing and able to act.
- Discuss both financial and welfare decisions.
- Think about replacement attorneys and how multiple attorneys should act.
- Allow time for proper signing and registration.
- Keep records of the documents and tell appropriate people where they are held.
Should I make a Will and LPAs together?
They do different jobs. A Will primarily deals with your estate after death; LPAs cover specified decisions during life. An LPA ends on the donor’s death and does not replace the authority needed to administer the estate.
Considering both together can make planning more coherent. The existing Will and LPA packages are Simple Will + 2 LPAs — £600, and Simple Mirror Wills + 4 LPAs — £1,100. No VAT is charged. OPG registration fees are separate. Suitability depends on your circumstances.
Frequently asked questions
What happens if I lose capacity without an LPA?
Relatives do not automatically gain general authority. Financial matters may require deputyship or another appropriate legal arrangement; welfare decisions follow the best-interests framework.
Does my spouse automatically become my attorney?
No. Marriage or civil partnership does not create a power of attorney.
Can my children access my bank account if I lose capacity?
Not simply because they are your children. The bank will normally need appropriate legal authority for someone else to manage a solely held account.
Can I make an LPA after losing capacity?
You must have capacity to make that LPA. If you lack it, someone else cannot create the LPA on your behalf.
Can someone with dementia make an LPA?
Yes, if they have the required capacity at the time. Diagnosis alone does not decide the question.
What is a Court of Protection deputy?
A person appointed by the court to make decisions within a specified order for someone who lacks the relevant capacity.
How long does deputyship take?
It depends on evidence, notifications, court processing and any disputes. There is no universal guaranteed timeframe; urgent applications are available only where appropriate.
Is deputyship expensive?
It can involve court fees, professional fees, supervision and security costs. Reductions or exemptions may apply; check current fees and obtain a case-specific estimate.
Can a deputy make health decisions?
Only where the court order authorises them. A financial deputy cannot assume welfare powers. Welfare deputyship is not routinely granted.
Do I need both types of LPA?
They cover different decisions. Consider both financial and welfare planning, but whether to make either or both is a personal decision requiring appropriate advice.
Is an LPA the same as a Will?
No. An LPA concerns decisions during life; a Will primarily directs what happens to your estate after death.
What happens to my LPA when I die?
It ends. Attorneys no longer have authority under it, and estate administration follows the relevant probate rules.
Thinking About Making an LPA?
LPAs are generally arranged while you have the required capacity. Planning in advance gives you the opportunity to choose people you trust, discuss your wishes and consider both financial and welfare decisions.
