DIY Lasting Power of Attorney vs Using a Solicitor: 2026 Cost Comparison
The gov.uk online LPA service is designed to be done without a solicitor, but complex family situations and property/business assets can make professional help worthwhile. A 2026 comparison.
What an LPA actually does
A Lasting Power of Attorney lets someone (the donor) appoint one or more people (attorneys) to make decisions on their behalf if they lose the mental capacity to do so themselves β or, for Property and Financial Affairs, optionally even while they still have capacity but want help. There are two separate types, each requiring its own document and registration:
- Health and Welfare LPA β covers decisions about medical treatment, care arrangements and daily welfare.
- Property and Financial Affairs LPA β covers decisions about bank accounts, bills, property and investments.

gov.uk provides an official online (and paper) LPA service specifically designed for individuals to complete without a solicitor β guiding the donor through appointing attorneys, choosing any restrictions or preferences, and identifying a certificate provider (an independent person confirming the donor understands and isn't being pressured) before submitting for registration with the Office of the Public Guardian. A registration fee applies per LPA, with fee remission or exemption available for those on certain lower incomes β check gov.uk for the current fee and eligibility.
Where the DIY route can go wrong
- Choosing attorneys without considering how they'll work together β joint attorneys can be required to act unanimously or allowed to act independently, and getting this wrong can cause practical problems later.
- Not tailoring guidance or restrictions where the donor has specific wishes beyond the standard template β the gov.uk service allows for this but it requires careful, precise wording to avoid ambiguity.
- Family disagreement about who should be appointed, which a solicitor may be better placed to help navigate sensitively and legally.
When a solicitor is worth the extra cost
- Significant or complex assets, including business interests, where tailored guidance to attorneys is valuable.
- Concerns about family conflict over the choice of attorney or how decisions might be made.
- Wanting bespoke restrictions or guidance that go meaningfully beyond the standard template options.
- Combining LPA planning with wider estate and Inheritance Tax planning, where a solicitor can look at the whole picture together.
A practical framework
| Situation | Suggested route |
|---|---|
| Straightforward family situation, standard wishes | gov.uk self-service is often entirely appropriate |
| Complex assets, family tension, bespoke wishes | Solicitor recommended |

Frequently asked questions
How much does it cost to register a Lasting Power of Attorney with the Office of the Public Guardian?
There's a registration fee per LPA payable to the Office of the Public Guardian regardless of whether it's completed via the gov.uk online service or with a solicitor's help β check gov.uk for the current fee, as well as any fee remission or exemption available for lower-income applicants.
Can I do a Lasting Power of Attorney myself without a solicitor?
Yes β gov.uk provides an official online (and paper) service specifically designed to let people complete both a Health and Welfare LPA and a Property and Financial Affairs LPA themselves, without needing a solicitor, though a certificate provider (an independent person confirming capacity and understanding) is still required.
When is it worth paying a solicitor for an LPA?
It's generally worth it where the donor's circumstances are complex β significant business interests, concerns about family disputes over the appointment, or where the donor wants tailored restrictions or guidance for the attorneys that go beyond the standard gov.uk template wording.
