Power of Attorney Cost Calculator

Budget for POA paperwork.

Calculate total Power of Attorney setup cost — solicitor fees plus registration — at the per-LPA price your provider charges.

What this tool does

This calculator estimates the total cost of setting up a Power of Attorney by combining solicitor fees and registration charges across your chosen document types and attorney count. The result shows the aggregate expense for completing the paperwork based on per-document fees you input. Solicitor fees and registration costs per document type drive the final total most significantly. A typical use case involves budgeting for financial authority alone or pairing financial and health/welfare documents together. The calculator assumes flat fees per document and does not account for variations in solicitor pricing, expedited processing charges, or any additional legal services beyond standard setup. This output is for cost estimation and educational illustration only and reflects a simplified model of actual expenses.

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. 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.

How the math works

Total = (solicitor + registration) × types of POA.

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. It is a starting point for thinking, not a commitment to a specific future.

Worked example

Assume a person arranges POA for both property/financial and health/welfare matters with one solicitor representing them. The solicitor charges 250 per document type and the registration authority charges 95 per document.

  • Solicitor fees: 250 × 2 types = 500
  • Registration fees: 95 × 2 types = 190
  • Total cost: 690

If the same person appoints two attorneys jointly (rather than one), the cost structure remains the same because fees typically apply per document, not per attorney listed on it. However, if solicitor fees are charged per attorney named, the total could rise to 990 or higher depending on the firm's pricing structure.

When this calculator matters

Setting up Power of Attorney is relevant in several situations:

  • Planning ahead for potential loss of mental capacity due to age or health condition
  • Comparing the cost of professional legal help against do-it-yourself completion
  • Budgeting for multiple document types and attorney appointments
  • Understanding how registration fees and legal fees combine to form total setup expense
  • Planning finances before unexpected circumstances force rushed decisions

What the result shows and does not show

This calculator shows the upfront cost of establishing Power of Attorney documents and registering them. It illustrates how solicitor fees, registration charges, number of attorneys, and document types multiply together to form a total expense.

The result does not include:

  • Ongoing fees for managing the attorney role after setup
  • Costs associated with challenging or updating the POA later
  • Fees for disputes between co-attorneys or court involvement
  • Variations in pricing between different solicitors or regions
  • Time costs incurred by the person preparing the documents themselves
  • Potential rejection costs if documents are incorrectly completed and require re-submission

Educational illustration

This calculator models costs based on inputs you provide. The output estimates total setup expense for budgeting purposes and is intended for educational illustration of how different fee structures combine. Actual costs depend on your jurisdiction, the solicitor selected, and the specific complexity of your circumstances.

Example Scenario

££200 + ££82 × 2 types = 564.00.

Sources & Methodology

Methodology

Adds solicitor fees and registration costs per document type, then multiplies by the number of POA types selected to produce a total setup cost estimate.

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.
Why does the number of attorneys affect the total cost?
The calculator multiplies combined solicitor and registration fees by the number of POA document types selected, not the number of attorneys named within each document. Adding a second or third attorney to a single LPA does not change the per-document fee structure in this model, though some solicitors do charge incrementally for each additional attorney named, which this simplified estimate does not capture.
What costs are not included in this estimate?
The calculator covers flat solicitor fees and registration charges only, so it excludes identity verification fees, certificate provider charges, notarisation for overseas use, court of protection fees if capacity is already in question, and any ongoing legal advice costs. Expedited processing and postage or printing for paper applications are also outside the scope of this model.
