What Happens If You Don't Have an LPA? The Real Consequences

Legal Guide8 min read13 April 2026

Quick Answer

Without an LPA, if you lose mental capacity your family will have no legal authority to manage your finances or make health decisions. They would need to apply to the Court of Protection for a deputyship, which costs thousands of pounds, takes 6–12 months, and involves ongoing court supervision.

Key Facts

  • Without an LPA, nobody has automatic authority to manage your affairs if you lose capacity.
  • Even your spouse cannot access your sole bank accounts without legal authority.
  • The alternative is a Court of Protection deputyship, which costs £1,000–£3,000+ to set up.
  • Deputyship applications take 6–12 months to process.
  • Deputies face ongoing annual supervision fees and reporting requirements.
  • The court decides who becomes deputy — it may not be who you would have chosen.
  • An LPA is much cheaper and faster than a deputyship.

What happens when someone loses capacity without an LPA?

If you lose the ability to make decisions for yourself — whether through dementia, a stroke, a brain injury, or any other cause — and you do not have a registered Lasting Power of Attorney, your family faces a difficult situation. Despite what many people believe, nobody automatically has the legal right to manage your affairs, not even your spouse, your children, or your next of kin.

This means your family cannot:

  • Access your bank accounts (except joint accounts)
  • Pay your bills or mortgage
  • Sell or rent your property
  • Make decisions about your medical treatment
  • Choose where you live or what care you receive
  • Deal with your pension, investments, or tax affairs

What is a deputyship?

The only alternative to an LPA, once someone has already lost capacity, is a Court of Protection deputyship. This is a legal process where someone (usually a family member) applies to the court to be appointed as your "deputy" — essentially a court-appointed equivalent of an attorney.

The key differences between a deputyship and an LPA are:

  • Cost: Deputyship applications cost £1,000–£3,000 or more in court and legal fees, compared to £131–£253 for an LPA through myLPA Guide.
  • Time: Deputyship takes 6–12 months to process, compared to 8–12 weeks for LPA registration.
  • Control: With an LPA, you choose your attorneys. With a deputyship, the court decides who is appointed — and it might not be the person you would have chosen.
  • Supervision: Deputies face ongoing supervision, annual reporting requirements, and annual fees. LPA attorneys do not.

How much does a deputyship cost?

The costs add up quickly:

  • Court application fee: £371
  • Assessment of capacity: £300–£500 (a doctor must confirm the person lacks capacity)
  • Solicitor fees: £500–£2,000+ (most people need professional help with the application)
  • Annual supervision fee: £320 per year (for property and affairs deputies)
  • Security bond: Required in most cases, typically £100–£300 per year

Over time, the ongoing supervision costs alone can amount to thousands of pounds. Compare this to the one-off cost of an LPA — £92 per document for the government fee, or £253 total for both LPA documents through myLPA Guide.

What problems do families face without an LPA?

The reality of not having an LPA is often deeply stressful for families:

  • Frozen bank accounts: Banks will freeze accounts once they become aware that the account holder lacks capacity. Bills go unpaid, mortgage payments are missed, and direct debits bounce.
  • Care home decisions: If someone needs to move into a care home urgently, there may be nobody with the legal authority to arrange and pay for it.
  • Property sales: If the family home needs to be sold to fund care, nobody can instruct an estate agent or sign legal documents.
  • Family disputes: Without a clear legal framework, family members may disagree about what is best. The court process can make these conflicts worse.
  • Medical decisions: Doctors will make decisions about treatment in the patient's "best interests" — but without input from someone who knows the patient's wishes.

Can you not just use a joint bank account?

A joint bank account allows the other account holder to continue using that specific account. However, it does not cover:

  • Sole accounts in the incapacitated person's name
  • Property sales or management
  • Pensions, investments, or ISAs
  • Tax affairs
  • Any health or welfare decisions

A joint account is not a substitute for an LPA.

It is too late once you lose capacity

The most important thing to understand is that you can only make an LPA while you still have mental capacity. Once you have lost the ability to understand what an LPA is and what it does, it is too late. You cannot make an LPA on behalf of someone who has already lost capacity — the only option at that point is the expensive and slow deputyship process.

This is why setting up an LPA is something to do now, while you are healthy and able. It is not about expecting the worst — it is about preparing for any possibility.

Frequently Asked Questions

Can my spouse manage my finances without an LPA?

No, not automatically. Your spouse can use joint bank accounts, but they have no legal authority over your sole accounts, property in your sole name, pensions, investments, or tax affairs without an LPA or deputyship.

How long does a deputyship application take?

Typically 6–12 months, sometimes longer. During this time, your family has no legal authority to manage your affairs, which can cause serious practical problems.

Can I make an LPA for someone who already has dementia?

Only if they still have sufficient mental capacity to understand what an LPA is. A doctor or the certificate provider would need to confirm this. If they have lost capacity entirely, the only option is a deputyship.

Is a will the same as an LPA?

No. A will only takes effect after you die. An LPA is for decisions while you are alive but unable to make them yourself. You need both.

What if nobody applies for a deputyship?

If no family member is willing or able to apply, the local authority may step in as deputy. This gives a public body control over your finances and care decisions — most people would prefer to have a trusted person acting for them.

Can the NHS make medical decisions without an LPA?

Yes, healthcare professionals can make medical decisions in your best interests without an LPA. However, they will not know your personal values and preferences. A Health and Welfare LPA ensures someone who knows you can advocate for your wishes.
