Challenging Solicitor Probate Fees UK: Your Rights Explained

Probate solicitor bills can be shockingly high. Beneficiaries and executors have clear legal rights to challenge them — but the window to act is short. Here is exactly what to do, step by step.

Why Solicitor Probate Bills Can Be So High

Solicitors typically charge for probate in one of three ways: a fixed fee, an hourly rate, or a percentage of the estate value. The percentage model — commonly 1–2% of the gross estate — is where overcharging most often occurs. On a £500,000 estate, 2% is £10,000 for work that may have taken 20–30 hours and would cost £3,000–£6,000 on a time-cost basis.

Families in the weeks after a bereavement are rarely in a position to negotiate or shop around. They sign the solicitor’s engagement letter without reading the charging basis carefully. By the time the bill arrives — sometimes months later — a large sum has been deducted from the estate.

The SRA Transparency Rules (2018) require solicitors to publish their probate pricing information online. If they do not, you can report them to the Solicitors Regulation Authority (SRA).

Your Rights Under the Solicitors Act 1974

The Solicitors Act 1974 gives clients and third parties (including beneficiaries) the right to challenge a solicitor’s bill through a process called assessment of costs(formerly called “taxation of costs”). The bill is reviewed by a costs judge at the Senior Courts Costs Office (SCCO) in London, or at a District Registry.

Key points:

  • Both the executor/administrator and beneficiaries can apply for assessment in certain circumstances (s71 Solicitors Act 1974).
  • You can apply without first paying the bill. In most cases the court will not order payment until after assessment.
  • The court assesses whether each item is reasonable in amount and reasonably incurred.
  • The costs judge can reduce or disallow any item.

Step-by-Step: How to Challenge the Bill

1

Request a detailed itemised bill

Under s69 Solicitors Act 1974, you are entitled to a detailed bill before paying a gross sum invoice. Write to the solicitor requesting a full itemised bill. The one-month clock for court assessment does not start until the detailed bill has been delivered.

2

Review the bill carefully

Check the hourly rate against what was agreed in the engagement letter. Check total hours — does the number of hours spent seem proportionate to the complexity of the estate? Look for double-charging (the same task billed twice), excessive correspondence charges, and items that are disbursements billed at a mark-up.

3

Write a formal letter before action

Write to the solicitor pointing out the specific items you dispute and proposing a reduced figure. Many solicitors will negotiate at this stage to avoid court proceedings. Keep everything in writing. Give the solicitor 14 days to respond before proceeding.

4

Complain to the firm's client care partner

All solicitor firms must have a complaints procedure. Escalate to the most senior partner if the initial response is unsatisfactory. Request a response within eight weeks.

5

Legal Ombudsman — if poor service is involved

If the solicitor gave poor service (delays, failure to respond, misleading costs information) as well as an inflated bill, complain to the Legal Ombudsman (legalombudsman.org.uk). LeO can order a fee reduction and compensation. Time limit: six years from the act, or three years from awareness. Must have gone through the firm's complaints process first.

6

Apply to the court for assessment

If negotiation fails and the matter is within one month (or up to 12 months with discretion) of bill delivery, apply to the Senior Courts Costs Office using Form N208 (a Part 8 claim) or a written application. Pay the court fee (£50–£155). The SCCO will list a detailed assessment hearing.

What “Reasonable” Means for Probate Costs

Costs judges apply the “indemnity basis” to solicitor-client bills: charges are allowed unless they were unreasonably incurred or are unreasonable in amount. In practice, a bill will be reduced if it can be shown that:

  • The work was over-staffed (a partner did work a paralegal could have done)
  • The hourly rate was not explained to you or exceeds the rate in the engagement letter
  • A percentage fee is grossly disproportionate to the time actually spent (no nexus between the fee and the work)
  • Disbursements (search fees, Land Registry fees) were marked up without disclosure
  • Work billed was unnecessary or duplicated across fee-earners

The Law Society’s guidance on probate pricing states that a percentage of estate value is one permissible basis but must be reasonable in all the circumstances. Courts have repeatedly held that a percentage fee that produces an amount wildly disproportionate to the time cost is not reasonable.

What Solicitor Probate Work Typically Costs in 2026

Estate typeReasonable range (solicitor)Red flag if above

Indicative ranges only. Actual costs depend on complexity, location, and firm. Disbursements (probate court fees: £300 for estates over £5,000; copies: £1.50 each) are additional.

How to Avoid Excessive Probate Bills: Practical Steps

  • Get three written quotes before instructing a solicitor. Prices vary significantly between firms for identical work.
  • Agree a fixed fee in writing. An hourly-rate engagement can spiral. Fix the fee or agree a capped hourly arrangement.
  • Refuse a percentage-of-estate basis unless you are satisfied the amount is proportionate. Calculate what the percentage fee means in pounds before signing.
  • Ask what work is included.“Full estate administration” should include collecting assets, paying debts, dealing with HMRC, preparing estate accounts, and distributing. Some firms charge extra for each element.
  • Consider doing it yourself. Straightforward estates are entirely manageable without a solicitor. HMRC and the Probate Registry provide guidance. The probate application fee is £300 for estates over £5,000 — the only unavoidable cost.

Frequently Asked Questions

Is there a time limit for challenging a solicitor's probate bill?

Yes. Under the Solicitors Act 1974, you must apply to the court for assessment of a solicitor's bill within one month of it being delivered (without consent). If you are between one month and twelve months after delivery, you can still apply but the court has discretion to refuse. After twelve months, you generally cannot apply unless you have already paid the bill in full and even then there are exceptional circumstances requirements. Act promptly — do not wait.

What is a 'detailed bill' and am I entitled to one?

A detailed (or itemised) bill sets out every disbursement and every chargeable unit of work — letters written, calls made, documents reviewed — with the time spent and hourly rate. Under the Solicitors Act 1974, you can demand a detailed bill as a condition of paying. The solicitor must provide one within a reasonable time. A 'gross sum' invoice that just says '£4,500 — probate services' is not sufficient if you ask for detail. Requesting a detailed bill also pauses the one-month clock for challenging the bill.

Can a solicitor charge a percentage of the estate for probate?

Yes, but only if you agreed to it in writing. A solicitor cannot unilaterally decide to charge 1–2% of the estate and present you with the bill unless the retainer (the engagement letter you signed) clearly stated that basis. If you agreed an hourly rate or a fixed fee, the solicitor is bound by that agreement and cannot switch to a percentage approach afterwards. Many families are overcharged because they did not read the engagement letter carefully — always ask for the charging basis before instructing a solicitor.

What is the Legal Ombudsman and can they reduce the bill?

The Legal Ombudsman (LeO) handles complaints about the service provided by solicitors — delays, poor communication, failure to keep you informed. LeO can order a solicitor to reduce a bill, refund money, or pay compensation, but only if the complaint is about service quality rather than purely about the amount charged. If you think the work was done well but the bill is disproportionate, a court assessment is the right route. If the solicitor also gave poor service (missed deadlines, didn't respond to calls), LeO adds value. Time limit: within six years of the act or omission, or within three years of you becoming aware of a problem.

How much will cost assessment proceedings cost me?

There is a court fee for applying — currently £50–£155 depending on the amount in dispute. If the court reduces the bill by more than one-fifth (20%), the solicitor normally pays the costs of the assessment proceedings. If the bill is reduced by less than one-fifth, you may be ordered to pay the costs. This means it is generally worth applying only if you believe the bill is inflated by at least 20%. In practice, many solicitors will negotiate a reduction when faced with an application rather than risk a full assessment.

Start with a Will That Simplifies Everything for Your Executor

A clearly drafted will reduces the complexity of estate administration and gives your executor the information they need — often making solicitor involvement unnecessary for straightforward estates.
