Contested Wills and Inheritance Act Claims

WillsLast reviewed: 1 April 202510 min

Challenging a will or making a claim against an estate is a significant legal step with strict time limits and formal requirements. There are two main routes: contesting the validity of the will itself (challenging whether it was made properly), and making a claim under the Inheritance (Provision for Family and Dependants) Act 1975 for reasonable financial provision where a will (or intestacy) does not make adequate provision for you.

Key points

  • An Inheritance Act 1975 claim must be brought within 6 months of the Grant of Probate or Letters of Administration being issued — missing this deadline is nearly always fatal to the claim.
  • People who can bring an Inheritance Act claim include a spouse or civil partner, a former spouse (if not remarried), a child of the deceased, a person treated as a child of the family, or someone maintained by the deceased immediately before death.
  • Cohabitants (unmarried partners who lived with the deceased for at least 2 years before death) can also bring an Inheritance Act claim.
  • The court considers the applicant's financial needs, the size of the estate, the needs of other beneficiaries, and any obligations the deceased had to the claimant.
  • Grounds for contesting a will's validity include lack of testamentary capacity, undue influence, fraud or forgery, and failure to comply with formal requirements.
  • Contesting a will is expensive and uncertain — most claims settle through negotiation or mediation before trial.

Inheritance Act 1975 Claims — Who Can Claim and For What

The Inheritance (Provision for Family and Dependants) Act 1975 allows the court to make provision from an estate for certain applicants where the will (or intestacy) has not made "reasonable financial provision" for them.

Who can apply:

  • The surviving spouse or civil partner of the deceased
  • A former spouse or civil partner who has not remarried and has not already obtained a financial settlement from the court
  • A child of the deceased (including adult children)
  • Any person who, while not a child of the deceased, was treated by the deceased as a child of the family (for example, a stepchild who was raised by the deceased)
  • Any person who was being maintained by the deceased immediately before their death (this includes other dependants who may not fit the above categories)
  • A person who lived with the deceased as their husband, wife, or civil partner for the whole of the period of two years ending on the date of the death (cohabitants)

What "reasonable financial provision" means:

  • For a surviving spouse or civil partner: such financial provision as it would be reasonable in all the circumstances for the applicant to receive, whether or not needed for maintenance — this is a higher standard.
  • For all other applicants: such financial provision as it would be reasonable for the applicant to receive for their maintenance — a lower, maintenance-based standard.

What the Court Considers and Possible Awards

When deciding an Inheritance Act claim, the court must consider a range of factors set out in section 3 of the Act, including:

  • The financial resources and financial needs of the applicant (now and in the foreseeable future)
  • The financial resources and financial needs of any other applicants and beneficiaries
  • Any obligations and responsibilities the deceased had to the applicant
  • The size and nature of the estate
  • Any disability of the applicant or any beneficiary
  • The conduct of the applicant and any other person
  • For a surviving spouse: the applicant's age, duration of the marriage, and their contribution to the family welfare

What the court can order:

  • A lump sum payment out of the estate
  • Periodical payments (ongoing maintenance)
  • A transfer of specific property from the estate
  • The acquisition of property out of the estate and its transfer to the applicant
  • The variation of a marriage settlement

The court has broad discretion and will try to achieve a fair outcome that meets the applicant's maintenance needs (or, for spouses, a fair share) without unduly prejudicing the other beneficiaries.

Challenging the Validity of a Will

Separate from Inheritance Act claims, you can challenge whether a will is legally valid. The main grounds are:

  • Lack of testamentary capacity: The testator did not understand the nature of making a will, the extent of their estate, or the claims of potential beneficiaries at the time of signing. Often relevant where the deceased had dementia, serious mental illness, or was heavily medicated.
  • Want of knowledge and approval: The testator signed the will but did not know and approve its contents — for example, where the will was prepared by a beneficiary and the testator was not able to read it or understand it properly.
  • Undue influence: The testator was coerced or pressured into making the will in a particular way by another person. Undue influence in will cases requires more than mere persuasion — it must have overborne the testator's free will. This is difficult to prove.
  • Fraud or forgery: The will was fraudulently altered or the testator's signature was forged.
  • Failure of formalities: The will was not properly executed — for example, the witnesses were not present at the same time, or the testator's signature was not in the right place.

To challenge a will's validity, you must enter a caveat at the Probate Registry before a Grant of Probate is issued. This prevents the grant being made and gives you time to pursue your challenge. A caveat lasts for 6 months and can be renewed. If the executor contests your caveat, the matter is referred to the courts.

Time Limits, Process, and Costs

Time limits — critical:

  • Inheritance Act claims: Must be issued within 6 months of the Grant of Probate or Letters of Administration. The court has discretion to extend this period but rarely does so unless there are exceptional circumstances. If you are considering a claim, take legal advice immediately after the grant is issued.
  • Challenging validity: Enter a caveat before the grant is issued. If a grant has already been issued, you will need to apply to "revoke" it, which requires court proceedings. There is no fixed time limit but delay can work against you.

Process:

  1. Pre-action: Write to the executors setting out the basis of your claim and requesting copies of relevant documents (the will, the estate accounts). Most claims settle without going to court.
  2. Mediation: Courts expect parties to consider alternative dispute resolution. Mediation is cheaper and faster than litigation and often achieves a better outcome for all parties.
  3. Issue proceedings: If negotiations fail, issue a claim in the Chancery Division of the High Court (for larger estates) or the County Court.

Costs: Contentious probate litigation is expensive. Both sides generally pay their own costs regardless of outcome (although the court has discretion to make costs orders). Legal aid is not available. Some firms offer conditional fee arrangements (no-win no-fee) for strong claims.

Frequently asked questions

My parent left everything to a new partner and nothing to me — can I claim?
Possibly. As a child of the deceased, you can make an Inheritance Act claim — but the standard for adult children is "maintenance," not a share of the estate. You would need to show a financial need for maintenance that the estate has failed to meet. The court takes into account the deceased's reasons for excluding you, the size of the estate, and your current financial situation. Adult children with comfortable financial circumstances often find it very difficult to succeed in Inheritance Act claims.
I lived with my partner for 5 years before they died without a will — can I claim?
Yes, you may be able to make an Inheritance Act claim as a cohabitant. To qualify, you must have lived in the same household as the deceased as their husband, wife, or civil partner for the whole of the two-year period ending on the date of death. The standard is "maintenance" — you must show that reasonable provision has not been made for your maintenance from the estate. You must issue your claim within 6 months of the Grant of Letters of Administration.
How do I find out if probate has been granted so I know my time limit?
Grants of Probate and Letters of Administration are public documents. You can search the Probate Registry's online service at gov.uk/search-will-probate to check whether a grant has been issued. Alternatively, you can enter a "standing search" at the Probate Registry, which will notify you automatically if a grant is issued in respect of a particular person's estate within the next 6 months.
Can I stop a Grant of Probate being issued while I consider my options?
Yes — by entering a caveat at the Probate Registry. A caveat costs £3 and prevents a Grant of Probate being issued for 6 months (renewable). The executor cannot proceed with the administration while the caveat is in place. However, the executor can issue a "warning" to the caveat, and if you do not respond within 8 days, the caveat is removed. If you receive a warning, take immediate legal advice.
