If you have suffered financial loss because a Will writer made an avoidable mistake when drafting, advising on, or arranging the execution of a Will, you may be able to bring a professional negligence claim against the Will writer (or their firm) to recover compensation. Errors in Will writing can be particularly distressing because they often come to light after a death, at a time when families are already dealing with bereavement, probate and estate administration. The impact can be significant: unintended beneficiaries, disappointed family members, increased inheritance tax, unnecessary disputes, and substantial legal costs.

What constitutes professional negligence by a Will writer?

Will writers are expected to use reasonable care and skill in the services they provide. This includes taking detailed instructions, advising on the different options and associated risks, correctly drafting and executing documents, and maintaining appropriate records.

A negligence claim typically arises where the Will writer’s work falls below the standard of a reasonably competent individual undertaking the same role in similar circumstances, and that failing causes a measurable financial loss.

The scope of the duty will depend on what the Will writer was instructed to do and what they held themselves out as able to advise on. Some Will writers are asked to prepare a straightforward Will. Others provide broader estate planning services, including advice on trusts, lifetime gifts, property ownership structures, or inheritance tax planning. Many disputes turn on whether the Will writer properly identified the testator’s objectives, asked the right questions, and gave clear advice about the consequences and risks of the chosen approach.

Common examples of Will writer negligence

Professional negligence claims against Will writers can arise in many different ways. Common examples include failing to draft a Will that properly reflects the testator’s instructions, including ambiguous wording that leads to competing interpretations, or omitting key provisions (such as residuary gifts, substitution clauses, or clear appointment of executors).

Other commons issues include failing to ensure that the Will is properly executed which deems the document invalid, unenforceable, and open to challenge. Claims also arise where the Will writer fails to advise on (or properly record and address) capacity concerns, vulnerability, or potential undue influence risks, increasing the likelihood of a contentious probate dispute that might have been avoided.

In estates with more complex assets, negligence allegations can include failure to advise on how property is owned (for example, the consequences of joint tenancy versus tenancy in common), failure to consider how business interests should pass, and failure to address tax consequences in circumstances where basic planning could have reduced avoidable liabilities. We also see claims involving lost or poorly stored original Wills, or delays in preparing a Will where the testator loses capacity or dies before signing.

Not every disappointed beneficiary has a negligence claim. Family disputes can arise even where advice was competent. The key question is whether the Will writer’s work fell below the required standard and whether the loss is attributable to that failing.

Time limits for bringing a claim

Limitation can be decisive in Will writer negligence claims and should be assessed as early as possible.

In broad terms, professional negligence claims are often subject to strict time limits, commonly running from when the cause of action accrues. Where the key facts were not reasonably discoverable at the time, a claimant may, in some cases, have additional time running from the date of knowledge and an overall “longstop” may apply. Limitation issues in Wills and estates can be complex because the loss may not crystallise until after death, probate, or the resolution of related disputes.

Where time is tight, parties sometimes agree a standstill while pre-action steps are followed, or proceedings may be issued and then stayed to allow the pre-action process to be completed.

The process for making a claim against a will writer

Early assessment and evidence gathering

We will usually begin by reviewing the retainer documentation, the Will and any previous Wills, the Will writer’s instruction notes, drafts and correspondence, and the probate file. We will also consider when the issue was discovered, what steps have been taken in response, and whether there are related proceedings (for example, a claim to construe the Will, or a challenge to validity).

At an early stage, our lawyers will advise you on what evidence is needed to prove breach and causation. This can include building evidence on the testators’ intentions, mental capacity, medical records, and the financial position of the estate.

Pre-action protocol for professional negligence claims

The Pre-Action Protocol for Professional Negligence provides a useful framework for claimants and sets out the key steps to pursue a professional negligence claim against a will writer. This includes early sharing of information and key documents. Letter of claim and response, discussions on settlement and ADR options.

Following the guidance under the protocol is important as it helps narrow down the issues, identify what has been agreed and what is disputed, and keeps costs proportionate.

Negotiation and alternative dispute resolution (ADR)

Many Will writer negligence claims settle without trial once liability and loss are properly set out. Where appropriate, ADR (including mediation) can be an effective way of resolving disputes, particularly where there are parallel probate disputes and a negotiated solution can draw a line under matters.

Issuing proceedings (if needed)

If settlement cannot be achieved, court proceedings may be required. We advise on the appropriate causes of action, the correct parties, evidence strategy and how best to manage any connected probate litigation so that the overall approach is coherent and cost-effective.

What remedies and compensation may be available?

The aim is usually to recover damages that, so far as money can, put you in the position you would have been in had competent services been provided. Depending on the facts, losses can include the value of an intended inheritance that was lost, additional tax incurred, increased administration costs, and legal costs that were reasonably incurred in addressing the consequences of the negligence.

You may be able to recover interest in some cases, and the appropriate remedy will depend on how the error impacted the estate and the claimant.

The legal test to bring a claim: Duty, breach and causation

Pen signing a contract

Duty of care

You need to show that the will writer owed you a duty of care. This is usually established through the retainer with the testator. In will drafting cases, however, the identity of the claimant can be a central issue. Depending on the circumstances, a claim may be brought by the estate (for example, where the estate incurred costs or tax that should have been avoided), or by an individual who has suffered loss because they did not receive an intended benefit.

Breach of duty

You must show that the will writer acted (or failed to act) below the standard of a reasonably competent professional providing the same service in the relevant circumstances. This often involves close analysis of instruction notes, drafts, attendance notes, communications, and the final document, as well as what advice was given (or not given) about execution, tax, and foreseeable dispute risk.

Causation and loss

You must show that the breach caused the loss. In practice, this typically requires demonstrating what would have happened if competent services had been provided. For example, would the Will have been valid, would the estate have been distributed differently, would an avoidable tax liability have been reduced, or would litigation and administration costs have been avoided?

Loss must be evidenced and quantified. This may involve comparing what the claimant received with what they should have received, assessing the costs of rectifying the position (for example, through deed of variation, court applications, or settlement of a probate dispute), and considering what mitigation steps were reasonable.
