Professional negligence in wills, trusts & estates advice

When a will, trust, or estate is handled negligently, the financial and emotional impact can be significant. Mistakes made by solicitors, will-writers, trustees, or financial advisers may result in lost inheritance, unexpected tax liabilities, or disputes between family members.

We are recognised as leaders in both professional negligence and contentious wills, trusts and estates. Our Professional Negligence, Dispute Resolution and Private Wealth Disputes teams are all ranked Tier 1 in the Legal 500, with the latter also ranked Band 1 in Chambers & Partners. These top-tier rankings reflect our ability to provide market-leading advice on negligence and estate disputes alike, giving clients complete confidence that their case is in expert hands.

We often advise beneficiaries and third parties who believe they ought to have been a beneficiary of a will but have lost out due to the will being poorly drafted or invalid (often known as “White v Jones” claims).

What is professional negligence in wills, trusts and estates?

Professional negligence occurs when a professional fails in their duty of care, causing loss. In this context, negligence might include:

Negligent will drafting:

  • Errors in wording or construction that invalidate a will.
  • Failing to ensure proper witnessing and execution.
  • Omitting beneficiaries or failing to reflect the true intentions of the person who made the will.

Negligent tax and estate planning advice:

  • Poor inheritance tax planning leading to avoidable liabilities.
  • Failure to advise on financial reliefs and exemptions.

Mishandling estates and trusts:

  • Delays or mistakes in administering an estate.
  • Trustees investing assets negligently.
  • Executors failing to act in beneficiaries’ best interests.

If you have suffered financial loss due to errors like these, you may have grounds for a professional negligence claim.

Mistakes in drafting, tax planning or estate administration can have lasting financial consequences. Our professional negligence specialists can advise you on whether you have grounds for a claim and the steps required to protect your position.

Recent case examples

We regularly act for executors, beneficiaries and family members who have suffered substantial financial loss as a result of negligent tax advice or poorly drafted wills. The following examples illustrate the types of claims we pursue and the outcomes achieved for our clients.

Case study 1:
Our client and her late husband sought advice from an Independent Financial Adviser (IFA) in order to gain expert advice on inheritance tax (IHT) planning. As part of the IHT advice, the IFA advised our client and her late husband to make substantial lifetime gifts to their children in order to reduce their multi-million-pound estate. At the time of making these gifts, the IFA was aware that our client’s husband was terminally ill. Despite the IFA’s advice that making the lifetime gifts would result in no IHT liability, upon the death of our client’s husband, our client was faced with an IHT liability of hundreds of thousands of pounds. We successfully pursued a negligence claim against the IFA on our client’s behalf.

Case study 2:
We acted for an individual who was appointed as an executor of his mother’s will. He was also one of two named beneficiaries under the will, the other beneficiary being his sister. The mother specifically instructed the solicitor who drafted her will that her estate was only to pass to her children. She specifically stated that the estate was not to pass to her grandchildren. Our client’s sister predeceased his mother by a number of months. Due to the failure by the solicitor to expressly exclude section 33 of the Wills Act 1837, despite the mother’s wishes, our client’s niece successfully brought a claim for 50% of the testator’s estate. We successfully pursued a claim on behalf of our client against the solicitor who had negligently failed to draft the will properly.

Frequently asked questions

Yes. If mistakes in drafting or execution cause financial loss, you may be entitled to bring a professional negligence claim.

There are time limits that apply to bringing a claim in professional negligence. Generally, if you wish to pursue a professional negligence claim it must be brought within six years from the date of the breach of contract (in a claim for breach of contract), or within six years from the date when the damage is suffered (in a negligence claim). However, these time limits can vary depending on various factors such as but not limited to, when a claimant ought to have become aware of the negligence.

The rules relating to limitation can be complex and full of pitfalls. Bringing your claim within the relevant “limitation” period is the essential first step to bringing a successful claim. It is therefore important to seek legal advice as early as possible to ensure that you are able to bring a claim.

Yes. For example, beneficiaries or intended beneficiaries may bring a claim if they were intended to benefit from a will but lost out due to negligence.

Many claims are resolved through negotiation or mediation under the Pre-Action Protocol. Court is only needed if settlement isn’t possible, but most cases settle before trial.
