Estate Challenges: Will disputes are reviewed under the Inheritance (Provision for Family and Dependants) Act 1975. Claims require robust evidence and legal support.

Contesting a will refers to the legal process by which a person challenges the validity, terms, or administration of someone's will after that person has died. In England and Wales, wills are governed by a combination of statutory law, common law principles, and court practice. Disputes can arise for a range of reasons, including concerns that the will does not reflect the deceased's true intentions, that it was created improperly, or that it fails to make reasonable financial provision for certain individuals. This article explains what it means to contest a will, who may be able to do so, how the process works, what time limits apply, and practical considerations for claimants and beneficiaries.

Understanding Wills and Probate

When a person dies leaving a valid will, the document expresses their wishes about how their estate (all their assets and liabilities) should be distributed. To give effect to a will, an executor must obtain a grant of probate, a legal document issued by the Probate Registry confirming the will's validity and the executor's authority to administer the estate. Once probate is granted, the executor can collect assets, pay debts, and distribute what remains according to the will. If no valid will exists, the estate is distributed according to the intestacy rules.

Contesting a will generally occurs either before probate is granted or after. Before probate, a formal challenge can delay or prevent the grant. After probate, disputes normally take the form of claims in the courts. Prompt action is usually critical because the longer the estate is administered and distributed, the harder it becomes to undo transactions or recover assets.

Grounds for Contesting a Will

There are two broad categories of dispute when contesting a will:

1. Validity Challenges

These claim that the will is legally defective or should not be given effect. Common grounds include:

  • Lack of testamentary capacity: The person who made the will (the testator) was not of sound mind or did not understand the nature of their property or the consequences of the will they were making.
  • Undue influence or coercion: Someone improperly pressured or forced the testator to make or change the will in a particular way.
  • Lack of knowledge and approval: The testator did not know or approve the contents of the document presented as their will.
  • Improper execution: The will was not signed and witnessed in accordance with the legal requirements set out in the Wills Act 1837.
  • Fraud or forgery: The signature or the document itself is fraudulent.

There is no fixed statutory time limit for many validity challenges, but acting without delay is essential. Once probate has been granted and estate administration completed, reversing distributions becomes more complex and may involve claims against those who have already received assets.

2. Claims Under the Inheritance (Provision for Family and Dependants) Act 1975

This is the most common basis for contesting a will in practice, even where the will is valid. The Inheritance Act 1975 allows certain family members and dependants to ask a court to make reasonable financial provision from the estate if the will (or intestacy distribution) fails to do so.

Individuals who may have a claim include:

  • A spouse or civil partner
  • A former spouse or civil partner (provided they have not remarried)
  • Children of the deceased (including adult children in some circumstances)
  • Persons who lived with the deceased as if they were a spouse or civil partner for at least two years immediately before death
  • Persons who were financially dependent on the deceased

To succeed, claimants must show that the will does not make reasonable financial provision for their needs, taking into account factors such as the size of the estate, the claimant's financial resources, and their relationship with the deceased.

Process for Contesting a Will

Before Probate Is Granted

If you believe there are genuine concerns about a will's validity, you can enter a caveat with the Probate Registry. A caveat prevents a grant of probate from being issued for six months, giving you time to investigate and seek legal advice. Caveats can be extended or replaced with a full claim if necessary.

After Probate Is Granted

Once probate is granted, you can pursue a claim in the courts. For validity challenges, there is generally no statutory limit, but delay can significantly weaken your case because assets may have been distributed to beneficiaries. For an Inheritance Act claim, you must issue proceedings within six months of the date of probate or letters of administration being granted. The court retains a limited discretion to allow a claim outside this period in exceptional circumstances, but this is uncommon.

The usual procedure involves:

  1. Assessing eligibility and grounds: Establish whether you have legal standing and a credible basis for your claim.
  2. Pre‑action steps: Before issuing court proceedings, claimants often send a letter of claim setting out the nature of the dispute and evidence supporting it.
  3. Court proceedings: If settlement negotiations fail, a claim is filed in the appropriate court (typically the High Court or County Court). The court will consider evidence, witness statements, and legal submissions.
  4. Judgment and orders: The court may declare a will invalid, rectify it, or award financial provision from the estate. Remedies vary according to the type of claim.

Time Limits and Key Deadlines

Time limits are a critical part of contesting a will:

  • Inheritance Act claims: Six months from the grant of probate or letters of administration.
  • Validity challenges: No strict statutory time limit, but prompt action is crucial.
  • Rectification claims under the Administration of Justice Act 1982 also typically require action within six months of probate.

Practical Considerations

Contesting a will can be expensive and emotionally demanding. Legal costs, time involved, and potential outcomes should be carefully weighed. In many cases, disputes are resolved through negotiation or alternative dispute resolution such as mediation. Early engagement with a solicitor specialising in contentious probate can improve the chances of a favourable outcome and help identify the most appropriate legal route.

Risks and Unintended Consequences

  • Costs: Legal fees can be significant, particularly if the case goes to a full trial.
  • Time: Proceedings can take many months or even years.
  • Relationship damage: Disputes over inheritance often strain or sever family relationships.
  • Uncertain outcomes: There is no guarantee of success; even a valid claim may be dismissed or yield limited financial benefit.

Key Takeaways

To contest a will in England and Wales means to formally challenge the document governing a deceased person's estate on legal grounds. Disputes generally fall into two categories: challenges to the will's validity and claims under the Inheritance (Provision for Family and Dependants) Act 1975 if reasonable financial provision has not been made. Time limits, particularly for Inheritance Act claims, are strict and require early action. The process is complex, involves formal court procedures, and requires careful preparation of evidence and legal arguments. Those considering a claim should seek expert legal advice at the earliest opportunity.
