Should I use a solicitor, do it myself, or use an online service?

When it comes to making a Lasting Power of Attorney, you have three main options: do it yourself using the free government tool, pay a solicitor, or use an online LPA service. Each has different costs, benefits, and risks.

This guide gives you a clear, honest comparison so you can choose the right option for your situation. For more information on LPAs generally, see the official GOV.UK guide.

How much does each option cost?

Option 1: DIY with the government tool

  • Form filling: Free
  • OPG registration: £92 per document
  • Total for one LPA: £92
  • Total for both LPAs: £184

Pros: Cheapest option. No third-party fees.

Cons: No error checking. No guidance on common pitfalls. No support if things go wrong. Confusing interface that many people struggle with.

Option 2: Solicitor

  • Solicitor fees: £400-£900 per document
  • OPG registration: £92 per document
  • Total for one LPA: £492-£992
  • Total for both LPAs: £984-£1,984

Pros: Professional legal advice. Face-to-face service. Can act as certificate provider. May offer storage.

Cons: Very expensive. Requires appointments. Can take weeks. Some solicitors use the same government forms you could fill in yourself.

Option 3: myLPA Guide (online service)

  • Questionnaire: FREE
  • Document generation: £39 per document (or £69 for both, saving £9)
  • Signing guide: £67 (optional)
  • Print and post: £25 (optional)
  • OPG registration: £92 per document
  • Total for one LPA: from £131
  • Total for both LPAs: from £253

Pros: Very affordable. Free questionnaire with live preview. Error checking. Do it from home at your own pace.

Cons: No face-to-face legal advice (though most people do not need it for a standard LPA).

What do I get for each price?

myLPA Guide (mylpaguide.co.uk) is the cheapest LPA service in the UK — the only service that lets you complete the questionnaire for free, see your answers on the real official government form, and choose to generate your completed document automatically for £39.

Compare that to a solicitor who charges upwards of £400 and often uses the same government forms, just filled in on your behalf during a meeting that may last 30 to 60 minutes.

When is a solicitor worth the cost?

A solicitor may be worthwhile if:

  • You have a complex financial situation — business interests, overseas property, or trusts.
  • There are family disputes about who should be an attorney.
  • You need advice on related legal matters like wills, trusts, or inheritance tax.
  • The donor has fluctuating mental capacity and you need professional assessment.

For the vast majority of people with straightforward circumstances, an online service provides everything you need at a fraction of the cost. See our detailed guide on whether you need a solicitor for an LPA.

What about other online services?

Other online LPA services typically charge between £80 and £200 per document. Some offer phone support, others provide only basic form-filling. None match myLPA Guide's combination of a free questionnaire, live official form preview, and the lowest price per document.

Which option saves the most money?

Here is the potential saving when creating both LPAs:

  • myLPA Guide vs cheapest solicitor: Save £731 (£253 vs £984)
  • myLPA Guide vs average solicitor: Save £1,231 (£253 vs £1,484)
  • myLPA Guide vs expensive solicitor: Save £1,731 (£253 vs £1,984)

That saving could pay for a holiday, home improvements, or simply stay in your bank account. The legal result is the same — a registered, valid Lasting Power of Attorney.

Frequently Asked Questions

Is a solicitor LPA better than a DIY one?

Legally, there is no difference. Both produce the same registered LPA document. A solicitor provides advice during the process, but for straightforward situations, an online service or DIY approach produces an equally valid LPA.

How much cheaper is myLPA Guide than a solicitor?

For both LPAs, myLPA Guide costs from £253 compared to £984-£1,984 through a solicitor — a saving of at least £731.

Is the government DIY tool difficult to use?

Many people find the government tool confusing. It uses legal language and provides minimal guidance, which is why thousands of LPAs are rejected each year due to errors.

Can I start with the free questionnaire and decide later?

Yes. The myLPA Guide questionnaire is free and there is no obligation to pay. You can complete it, see your answers on the official form, and then decide whether to pay £39 to generate the document.

Do online LPA services produce legally valid documents?

Yes. Online services like myLPA Guide produce the same official LPA forms that solicitors use. Once registered with the OPG, they are equally valid.

What if I make a mistake with the DIY option?

If your LPA is rejected by the OPG, you may need to start over and pay the £92 registration fee again. This is one reason many people prefer a service with error checking, like myLPA Guide.
