When to Get a Lasting Power of Attorney UK (2026): The Right Time to Start

Yes — provided the person still has mental capacity at the time they make the LPA. A diagnosis of dementia or another condition that affects cognitive ability does not automatically mean a person lacks mental capacity. The test under the Mental Capacity Act 2005 is decision-specific and time-specific: can the person understand the information relevant to the LPA, retain it, weigh it up, and communicate their decision? Many people with an early-stage dementia diagnosis retain full capacity for months or years. However, as the condition progresses, capacity fluctuates — a 'good day' assessment by a GP or mental capacity professional (ideally used as the LPA's certificate provider) is important to document. If the person's capacity is in doubt, a solicitor should oversee the process. Acting quickly after diagnosis is essential; every month of delay narrows the window.

Without an LPA, no one — not even a spouse, adult child, or close relative — has automatic legal authority to manage your finances or make decisions about your care. To gain that authority, a family member or friend must apply to the Court of Protection to be appointed a deputy. A deputyship application costs approximately £1,000 in court fees and professional costs, takes six to twelve months to process, requires an annual report to the OPG (an ongoing administrative burden), and gives the deputy less flexibility than an attorney under a well-drafted LPA. The Court of Protection appoints only one deputy for property and financial affairs (for health and welfare, deputyship is rarely granted at all — decisions go to the court case by case). You lose the ability to choose who acts for you, and the process can be financially and emotionally exhausting for families.

The Office of the Public Guardian (OPG) currently takes around 20 weeks to register an LPA from the date the completed forms are received. This has improved from over 40 weeks in 2022–23 but remains substantial. The registration cannot begin until: the LPA forms (LP1F for property and financial affairs, LP1H for health and welfare) are fully completed, the certificate provider has signed, and any required people have been notified (under a 'notify people' step). Total elapsed time from deciding to make an LPA to having a registered document in hand is typically five to six months, assuming no mistakes in the paperwork. Errors on the forms cause the OPG to return them for correction, adding further weeks. A solicitor or specialist LPA service reduces the risk of errors.

The OPG registration fee is £92 per LPA — reduced from £82 per LPA under the 2023 fee changes (the reduction came into effect November 2023). Most people make both types (Property & Financial Affairs and Health & Welfare), so the registration fee is £184 total. People who receive certain means-tested benefits qualify for a 50% fee remission (£46 each), and those with a gross annual income under £12,000 may apply for full fee exemption. If you use a solicitor to prepare the forms, expect to pay £300–£700 for both LPAs. WillSafe UK sells an LPA Guidance Pack (£25) with plain-English instructions for completing the official forms yourself. The cost of not having an LPA — a deputyship application — is typically £1,000–£2,000 in fees plus ongoing annual costs.

Yes. LPAs are commonly associated with the elderly, but any adult can lose mental capacity suddenly — through a road accident, a stroke, a serious illness, or emergency surgery. If a 30-year-old is involved in a car accident and is incapacitated, their partner has no legal authority to access their bank account, pay their mortgage, or make medical decisions for them without going to the Court of Protection. This is also important for unmarried couples: there is no equivalent of the spousal right in English law — cohabiting partners have no automatic authority. Financial institutions will not discuss a sole account holder's affairs with anyone, including a live-in partner, without a registered LPA or court order.

Yes — illness alone does not prevent making an LPA. The determining factor is mental capacity, not physical health. A person with a terminal diagnosis, recovering from a stroke, or living with Parkinson's disease can make a valid LPA provided they have capacity at the time. A GP or qualified mental capacity professional can assess and certify capacity and act as the LPA's certificate provider. The sooner an LPA is made after a serious diagnosis, the safer: capacity can fluctuate or decline, and the OPG takes around 20 weeks to register the document. Waiting risks losing capacity before registration is complete.

Review your LPA whenever significant life events occur: marriage or civil partnership (note that marriage does not revoke an LPA in England and Wales — unlike a will); divorce or separation (an ex-spouse remains as attorney unless the LPA is revoked); death or incapacity of an attorney; or a major change in your relationship with your attorney. There is no formal 'expiry date' on an LPA, but outdated attorney appointments create practical problems — if your sole attorney dies or is themselves incapacitated, you may need a new LPA or a court order. It is good practice to review both LPAs every five years. If you need to revoke and replace, register the new LPA before revoking the old one, as OPG registration takes around 20 weeks.
