Lasting Power of Attorney (LPA) allows someone to make decisions for you if you lose mental capacity. Two types: property/financial and health/welfare. Cost: ~82 registration fee per LPA plus solicitor fees (150-400) if used. This calculator sums total setup cost.

200 solicitor fee × 2 types + 82 × 2 registration = 564 total. DIY route without solicitor: 164 registration only. The DIY saving is 400 but requires careful completion of the 22-page form - mistakes cause rejection requiring re-registration.

The tool works for any country by taking fees as user inputs. Power of Attorney typically costs 200-500 for both types. Most systems charge registration separately from legal advice. Costs scale with number of attorneys (co-decision-makers) and complexity of instructions.

Run it with sensible defaults

Using solicitor fee per lpa of 200, registration fee per lpa of 82, number of attorneys of 2, types of poa of 2, the calculation works out to 564.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Solicitor Fee per LPA, Registration Fee per LPA, Number of Attorneys, and Types of POA — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

How the math works

Total = (solicitor + registration) × types of POA. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using this to think, not predict

Financial plans are wrong by month six — new information arrives and reshapes the picture. The point of running projections isn't to be right in ten years; it's to be less wrong in the decision you're making this week.

What this doesn't capture

Real plans get re-run against new information every year or two. The result here is a reasonable direction, not a destination. Treat it as a starting point for thinking, not a commitment to a specific future.

Example Scenario

£200 £ + £82 £ × 2 types = $564.00.

Inputs

Solicitor Fee per LPA:200 £
Registration Fee per LPA:82 £
Number of Attorneys:2

Expected Result$564.00

Frequently Asked Questions

Solicitor vs DIY?
DIY saves 400 per LPA but requires correct completion. 1 in 10 DIY applications are rejected for errors - re-registration costs another 82. For complex estates, business ownership, or multiple attorneys, solicitor is usually worth the fee.
When to set up?
Before needed. Once mental capacity is lost, LPA can't be registered - court-appointed deputyship becomes required (much more expensive and time-consuming). Most advice: set up at 60-65 or upon diagnosis of any progressive condition.
