Lasting Power of Attorney UK: DIY or £600 Solicitor?

A Lasting Power of Attorney UK is a single form that lets someone you trust manage your money and your medical care if you lose the ability to do it yourself. It costs £92 through gov.uk, or £184 if you want both types. A high-street solicitor will draft the same form for £300 to £600 per type and most of the time you will not need their input on anything that matters. For the typical UK adult, the gov.uk DIY route is the right answer.

That is the contrarian case the top Google results will not make. The first five search results for "lasting power of attorney uk" are gov.uk, the gov.uk LPA service portal, Age UK, and SCIE. Authoritative, careful, and structurally unable to say "skip the solicitor". This article makes the case directly, costs both options against the only one that matters (the Court of Protection bill if you do nothing), and flags the cohabiting-partner trap that the official guides bury.

What an LPA Actually Is

A Lasting Power of Attorney is a legal document that names one or more people (your attorneys) who can make decisions on your behalf if you lose the mental capacity to make them yourself. "Mental capacity" in UK law means the ability to understand a decision, retain the information long enough to make it, weigh the consequences, and communicate the choice. The benchmarks come from the Mental Capacity Act 2005.

Without an LPA, no one has automatic legal authority over your affairs. Not your spouse. Not your civil partner. Not your adult children. Not your parents. Your bank will freeze the account if it learns you have lost capacity. The building society will refuse to release funds. The conveyancing solicitor will not let your husband sell the family home. The whole machinery stops dead until someone applies to the Court of Protection to be appointed as your Deputy. That process is slow, expensive, and supervised by the court for the rest of your life. (The same legal-authority gap shows up around death too, where the inheritance tax UK guide covers what happens to the estate before probate releases it.)

The LPA solves this by naming the decision-maker in advance, while you still have the capacity to choose. The form is read by the Office of the Public Guardian (OPG) and held on a register. Once registered, your attorney can use it the moment capacity is lost. Banks, hospitals, care homes, and conveyancers all accept it as authority without further argument.

The LPA replaced the older Enduring Power of Attorney (EPA) for new applications in October 2007. Existing EPAs made before that date remain valid but only cover property and finance, not health and welfare. The Northern Ireland equivalent is still EPA. The Scottish equivalent is the Continuing Power of Attorney (CPA), which works similarly but is registered with the Office of the Public Guardian Scotland. The fees and process described below are for England and Wales.

The Two Types: Property and Welfare

There are two separate LPAs and most people who think they have "an LPA" only have one of them.

Property and Financial Affairs LPA. Covers your bank accounts, investments, property, pensions, and tax affairs. Your attorney can pay your bills, run your savings, sell your house, file your Self Assessment. You can choose to allow the attorney to act while you still have capacity (useful if you travel or are physically unable to handle paperwork) or only once capacity is lost. This is the LPA banks, building societies and HMRC will ask to see.

Health and Welfare LPA. Covers medical treatment, care home choice, daily routine, and life-sustaining treatment decisions. Your attorney can only act once you have lost capacity. You choose whether the attorney can refuse or consent to life-sustaining treatment on your behalf. This is the LPA hospitals and care homes will ask to see.

The two are sold separately and registered separately. You can make one without the other. You can name different attorneys on each. Most couples make all four (one Property LPA and one Welfare LPA each, with the spouse as attorney) so that either partner can step in if the other loses capacity. £184 covers both for one person at gov.uk. £368 covers all four for a couple.

People who tell you "I have set up power of attorney" almost always have only the Property version. The Welfare version is the one that lets your wife decide whether you go into a nursing home. Make both.

The £92 vs £600 Maths

The Office of the Public Guardian charges £92 to register one LPA. £184 for both. Both fees were verified at gov.uk/power-of-attorney/register in June 2026. The OPG also operates a fee remission scheme: £46 per LPA if your gross annual income is under £12,000, and a full exemption if you receive certain means-tested benefits including Income Support, Income-based Jobseeker's Allowance, or Guarantee Credit element of Pension Credit. The remission is decisive for low-income readers and frequently missed by solicitor-led routes.

A high-street solicitor charges in addition to the OPG fee. Typical UK pricing in 2026 runs £300 to £600 per LPA for a straightforward case (one donor, one or two attorneys, standard clauses), or £600 to £1,200 for both LPAs together. The all-in cost is therefore £92 to £184 if you do it yourself, or roughly £800 to £1,400 once you fold in the solicitor's fees on top of the OPG registration. The solicitor's bill is roughly £500 to £1,000 of admin tax for a form most people do not need legal advice to complete.

The gov.uk online form does the heavy lifting that solicitors used to charge for. It walks you through the questions one at a time, validates the entries, generates a PDF you sign and post, and includes plain-English guidance on every clause. The form is the same form the solicitor uses (LP1F for Property, LP1H for Welfare). The OPG accepts both routes identically.

The case for the solicitor is not the form itself, which is not complicated. The case for the solicitor is judgment on the small set of decisions where the form gives you a choice. Most readers do not need that judgment.

When a Solicitor Genuinely Earns the Fee

There are five situations where the £500 to £1,000 of solicitor input is worth paying. If you are in one of them, do not DIY.

1. You own a business. Property LPAs interact with company law in non-obvious ways. If you are a sole director, a partner in a partnership, or a limited company shareholder with meaningful holdings, you want the attorney's powers tailored. A standard LPA will not automatically let the attorney run a business that depends on you signing things.

2. Blended family with stepchildren or estranged biological children. If there is realistic potential for a family dispute over the attorney's decisions, the solicitor's role is partly to draft restrictions and instructions that head off the dispute, and partly to be a witness later that the form was made with capacity and without coercion. The witness role is the value, not the drafting.

3. Vulnerable beneficiaries or attorneys. If your attorney has their own mental-health vulnerabilities, addiction issues, or a history of financial difficulty, you want bespoke restrictions on what they can do with your money. Standard LPA clauses give the attorney broad powers.

4. Overseas assets, foreign property, or non-UK domicile. A UK LPA does not automatically reach an Italian villa or a Jersey trust. Solicitor advice on which jurisdictions need their own power-of-attorney equivalent saves headaches at the point of incapacity.

5. You are signing the LPA close to a known capacity threat. Early-stage dementia diagnosis, an approaching surgery with capacity risk, a degenerative condition. The solicitor's role here is to be the witness who can later defend the capacity assessment if the LPA is challenged. Their letter of opinion is worth its weight in gold if a family member contests the registration.

If none of those apply, the solicitor is paying for advice you do not need on a form that does not need it. £500 to £1,000 of pure friction.

Capacity Is Binary: Do It While You Do Not Need It

The single most-misunderstood thing about LPAs is the timing. You can only make an LPA while you have mental capacity. Once capacity is gone, the LPA is no longer available as a route. Your family will be pushed onto the Court of Protection Deputyship process instead.

This inverts the natural "I will do it later" reflex. You are not making an LPA because you currently need one. You are making it because if you wait until you need one, you cannot have one. The window of opportunity is the period when you do not yet need it. That is the whole structural point.

Capacity loss is rarely a smooth tail-off either. The textbook progression in dementia is a series of step-downs, often punctuated by an event (a fall, an infection, a stroke) that triggers a sharper drop. There is a real risk that the moment the family says "we need to sort this out" is the moment the donor has just dipped below the capacity threshold. An LPA signed at that moment can be challenged and refused at registration.

The practical rule: every UK adult over 18 should consider making both LPAs once they have property, savings, or dependants. The risk does not start at 65. A 30-year-old who has a stroke or a serious car accident faces exactly the same capacity question. The cost is £184 and one Sunday afternoon. The cost of having waited is a year of family pain and £1,500 to £2,500 of Deputyship fees while the bank account is frozen. This is the same argument the generational wealth article makes for gifts during life rather than after death: the earlier the decision is made, the more useful it is by the time anyone needs it.

The "Next of Kin" Myth and the Cohabiting Trap

There is no legal concept of "next of kin" in English or Welsh law that gives an adult relative or partner automatic authority over your finances. The phrase exists for medical purposes (hospitals will identify a next of kin for informal updates) and the inheritance rules of intestacy if you die without a will. It does not exist for capacity-loss decisions. Without an LPA, no one has the authority by default.

This affects married couples and civil partners less than it affects cohabiting partners, but it affects all of them. The bank will not let your wife operate your sole account just because she is your wife. The building society will not let your husband sell the house in his name only on the grounds of marriage. They will ask for the LPA, and if there is no LPA they will refuse and tell you to apply for Deputyship.

The cohabiting version is worse. England and Wales does not recognise common-law marriage. A 20-year cohabiting partner has no automatic financial rights at all if their partner loses capacity. The bank will treat them as a non-relative. The Court of Protection will weigh their application for Deputyship against any biological relatives, even ones the partner has not spoken to in decades. The outcome is unpredictable and slow.

For unmarried couples, the Property LPA is the only mechanism by which the surviving partner gets a guaranteed voice over the other's finances if capacity is lost. The £92 fee is one of the highest-leverage spends in UK personal finance for a cohabiting couple. The same cohabiting trap shows up in inheritance tax, where partners get no spousal exemption and a £500,000 estate can lose £70,000 to HMRC that married couples would not; the life insurance in trust UK guide covers the IHT version of the same structural problem. The Welfare LPA matters too: without it, the cohabiting partner does not have the right to make medical-treatment decisions, and hospitals may default to biological relatives.

If you are cohabiting and you read only one section of this article, this is the one to act on this week.

What Happens Without an LPA: Deputyship

If a UK adult loses mental capacity and there is no Property LPA in place, the family's only route to managing their affairs is Deputyship through the Court of Protection. This is the fallback the LPA exists to avoid.

The Court of Protection fees (verified at gov.uk/become-deputy/fees in June 2026):

• Application fee: £421.
• New deputy assessment fee: £100.
• Annual supervision fee: £320 (or £35 for "minimal supervision" cases where the estate is under £21,000).
• Possible hearing fee if the court needs one: £259.
• Security bond: variable, based on the value of the estate being managed.

The court-fee total in year one is roughly £521 to £840 before solicitor input. Solicitor fees for a contested or complex Deputyship application typically add £1,000 to £3,000. The application takes three to nine months and the bank account is frozen for most of that time, which means bills do not get paid, mortgage instalments may be missed, and care-home fees can pile up.

After year one, the Deputy is supervised by the OPG for the rest of the donor's life, paying £320 a year, filing annual reports, and getting permission for larger decisions. Over a 15-year case the total cost of Deputyship can comfortably exceed £6,000 before any solicitor involvement.

The LPA is the £92 form that prevents all of this. Framed as insurance, the premium is one-time, the cover is unlimited, and the alternative is the most expensive admin tax in the UK personal-finance system.

How to Do It Yourself at gov.uk

The DIY path is one URL: gov.uk/power-of-attorney. The steps are:

1. Decide your attorneys. One person or several. If several, decide whether they act "jointly" (must agree on every decision) or "jointly and severally" (any one of them can act alone). Jointly-and-severally is the standard choice for couples with adult children, because it stops a single missing attorney blocking a decision.
2. Decide the type or types. Make both Property and Welfare unless you have a specific reason not to. The £184 cost stays the same whether you do them on the same day or split them out.
3. Fill in the form online. The gov.uk service walks you through each section. Allow 30 to 45 minutes per LPA the first time you use it. Save and return if needed.
4. Print, sign and witness. The PDF generated by the service is signed by you, by each attorney, and by a "certificate provider" (someone who confirms you understood what you were signing, who must be unconnected to your attorneys). The certificate provider is usually a GP, solicitor or long-standing friend.
5. Post to the OPG with the £92 or £184 fee. Cheque or BACS. Apply for fee remission at the same time if your gross income is under £12,000.
6. Wait 8 to 20 weeks for registration. The OPG processing time has lengthened post-Covid and during the digital-application rollout. The LPA is not usable until registration is confirmed.

The Office of the Public Guardian's online service is genuinely good. It is one of the better pieces of UK digital government, and it has been refined over a decade. Use it.

Frequently Asked Questions

Can I do a Lasting Power of Attorney without a solicitor?

Yes. The gov.uk online service walks you through both LPA types step by step, validates each entry, and generates the official OPG-accepted PDF. Most UK adults can complete both LPAs in 30 to 45 minutes per type. The £92 OPG fee is identical whether the form was filled in by you or by a solicitor. The solicitor's role is judgment on edge cases (business ownership, blended families, complex assets, overseas property, capacity-threat timing), not the form itself. If none of those apply, the DIY route is the right call.

What does Martin Lewis say about Lasting Power of Attorney?

Martin Lewis has been hammering one point about LPAs for over a decade: every UK adult over 18 should have one, the gov.uk DIY route is fine for the vast majority, and waiting until you "need" one is the mistake that pushes families onto the Court of Protection. His MoneySavingExpert guide goes further on capacity-threat timing than most official sources, on the grounds that the cost of waiting is the asymmetric risk. That position aligns with this article. He also recommends fee remission for low-income applicants, which is genuinely under-claimed.

What are the negatives of a Lasting Power of Attorney?

The two real downsides are: (1) once registered, your attorney has the legal authority to operate inside your estate, so the choice of attorney matters enormously. Pick someone you trust without reservation. (2) The LPA cannot be revoked unilaterally if you later lose capacity; if you want to change attorneys you must do so while you have capacity. Both are reasons to make the choice deliberately, not reasons to skip the LPA. The downside of not making one (Deputyship via the Court of Protection, frozen bank accounts, months of waiting) is dramatically worse than either of these.

What is the difference between a Power of Attorney and a Lasting Power of Attorney?

A general or "ordinary" Power of Attorney is a short-term document that lets someone act for you while you have capacity (typically while you are abroad, in hospital, or otherwise unavailable). It ceases to be valid the moment you lose capacity. A Lasting Power of Attorney is specifically designed to continue working once capacity is lost: that is its defining feature. The LPA is what you want for capacity-protection. The ordinary PoA is what you want for short-term practical convenience. They are different forms and different products.

How much does a solicitor charge to set up a Power of Attorney?

UK solicitor fees in 2026 typically run £300 to £600 for a single LPA, or £600 to £1,200 for both LPAs at the same time. The all-in cost including the OPG's £92 registration fee per LPA therefore runs roughly £400 to £700 per LPA, or £800 to £1,400 for both. The DIY equivalent via gov.uk is £184 for both LPAs. The £500 to £1,000 saving makes sense for most readers; the cases where the solicitor genuinely earns the fee are listed above.

What is the difference between an LPA and a will?

A Lasting Power of Attorney covers decisions while you are alive but have lost capacity. A will covers what happens to your assets after you die. They are complementary. The LPA stops working at the moment of death; from that point the executor named in your will takes over. You generally want both. A will without an LPA leaves a gap during any period of lost capacity before death. An LPA without a will leaves the intestacy rules deciding who inherits.
