How to Challenge a Will for Partial Intestacy

A will may not always dispose of all of a person's assets. When this happens, partial intestacy arises - meaning the will is valid in part but fails to deal with some property or interests. In such cases, the law of intestacy applies to the assets the will did not dispose of. However, partial intestacy can become a source of dispute among beneficiaries or relatives, especially where there is genuine uncertainty or unfairness about how the intestate portion should be distributed. This article explains what partial intestacy is, why it occurs, the legal challenges that may arise, and the steps someone might consider in response.

What Is Partial Intestacy?

Partial intestacy occurs when a person dies leaving a valid will, but the will does not dispose of all of their estate. In that situation, the part of the estate that is not dealt with by the will is distributed under the statutory intestacy rules rather than the terms of the will itself. A partial intestacy may arise for several reasons, such as:

• omission of certain assets from the will;
• gifts that fail (for example where a beneficiary predeceases the testator and no substitute is provided); or
• inadequately drafted provisions that are incapable of taking effect for particular property.

Under the rules, the estate is divided according to a fixed order of entitlement set out in the Administration of Estates Act 1925 as amended, with different priorities for spouses, children, and other relatives.

Why Partial Intestacy Can Cause Disputes

Although partial intestacy does not arise in every contested will situation, it can become contentious when:

• beneficiaries named in the will receive conflicting or uncertain shares because some assets pass under intestacy rules;
• potential beneficiaries under the intestacy rules believe they should inherit part of the estate;
• relatives or dependants believe the intestacy outcome is unfair or unexpected; or
• there is uncertainty about whether property was effectively disposed of in the will.

For example, if the will leaves all residuary assets to a beneficiary but fails to deal with a specific property or interest, that omitted asset may pass by intestacy and give rise to claims from relatives who would otherwise take under the intestacy rules.

Legal Rights to Challenge or Address Partial Intestacy

1. Interpretation or Rectification of the Will

In some cases, partial intestacy results from unclear or defective drafting rather than genuine oversight. If the wording of the will is ambiguous, a court may be asked to:

• interpret the intention of the testator to give effect to provisions that appear to omit assets, or
• rectify the will under Section 20 of the Administration of Justice Act 1982 where there is evidence that a drafting mistake caused the failure to dispose of an asset.

These remedies help clarify or correct the will so that partial intestacy might be avoided. Interpretation or rectification claims must usually be brought within six months of the Grant of Probate, although the court can extend time in some circumstances.

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

Partial intestacy can create situations where some relatives or dependants receive little or nothing. The Inheritance (Provision for Family and Dependants) Act 1975 gives eligible persons (such as spouses, civil partners, children, and certain dependants) the right to apply to the court if the combined effect of the will and intestacy rules does not make reasonable financial provision for them. This is separate from a challenge to the will's technical validity. A 1975 Act claim must be issued within six months of the grant of probate or grant of letters of administration.

3. Validity Challenges

In some rare cases, partial intestacy may arise because the will is ineffective as to some assets due to formal defects. For example, if certain provisions were not properly witnessed or were invalid due to lack of testamentary capacity, those parts may be treated as if they were never made. A beneficiary might therefore challenge the will on grounds of lack of due execution, lack of capacity, undue influence, or fraud as a route to testing whether the will should be upheld or set aside in part. There is no strict time limit for validity challenges, though delaying action after probate can make recovery of assets more difficult.

Practical Steps When Partial Intestacy Is Suspected

Step 1 - Review All Testamentary Documents

Begin by obtaining a full copy of the will, any codicils, and related documents. This helps establish exactly which assets the will disposes of and where omissions may have occurred.

Step 2 - Identify Any Omitted Assets

Determine whether there are assets that fall outside the will's provisions. Common omissions include jointly owned assets, life insurance policies, digital assets, business interests, or assets acquired after the will was made.

Step 3 - Seek Specialist Legal Advice

Consult a solicitor experienced in contentious probate and estates law. Partial intestacy issues are often fact‑specific and require detailed analysis of wills, property ownership, and intestacy legislation.

Step 4 - Consider a Caveat

If probate has not yet been granted and you believe partial intestacy is at issue, entering a caveat at the Probate Registry can temporarily prevent a grant of probate and give time to assess the situation. A caveat lasts for six months and can be renewed.

Step 5 - Negotiate or Mediate

Before issuing court proceedings, affected parties may attempt mediation or negotiation to resolve disputes about assets or shares in the estate. Early settlement often reduces cost and emotional strain.

Step 6 - Issue a Court Claim

If informal resolution fails, solicitors can prepare and issue the relevant court proceedings, whether for interpretation, rectification, a 1975 Act claim, or a validity challenge, depending on the circumstances.

Time Limits and Practical Considerations

Time limits vary by the type of claim:

• Inheritance Act claims: generally must be issued within six months from the date of grant of probate or letters of administration.
• Rectification or interpretation claims: should ideally be made within six months of probate, although extensions may be sought.
• Validity challenges: have no strict statutory deadline but become harder after probate and distribution of assets.

Delays can make recovery of assets that have passed under intestacy more complicated or even impossible without the agreement of beneficiaries.

Potential Outcomes of a Partial Intestacy Challenge

Depending on the nature of the dispute and evidence:

• the court may interpret or rectify the will to include omitted assets;
• intestacy rules will govern distribution of omitted assets if no successful challenge is mounted;
• a successful Inheritance Act claim may result in additional provision for eligible claimants; or
• a part of the will may be found invalid, triggering intestacy for that portion.

Each outcome depends on specific facts, the strength of evidence and legal argument, and the court's discretion.

Risks and Considerations

Challenging issues related to partial intestacy involves risks:

• legal and court costs may be substantial;
• disputes can cause strain between family members;
• outcomes are uncertain and depend heavily on factual circumstances.

Early and specialised legal advice is essential.

Common Questions

If a will does not mention a property, does it automatically pass under intestacy?
Yes. Any asset not effectively dealt with by the will that does not pass by survivorship or trust will fall into intestacy and be distributed in accordance with statutory rules.

Can beneficiaries negotiate an alternative distribution?
Yes. Beneficiaries can agree among themselves and enter into a deed of variation to modify how assets are distributed, but all affected parties must agree.

Does partial intestacy mean the entire will is invalid?
No. Partial intestacy means only the omitted assets are distributed under the intestacy rules. The valid parts of the will stand.

Key Takeaways

Partial intestacy arises when a valid will fails to dispose of all of a person's estate. In such cases, the statutory intestacy rules apply to the omitted assets, which can lead to disputes among relatives or beneficiaries. Challenges may involve interpretation or rectification of the will, claims under the Inheritance (Provision for Family and Dependants) Act 1975, or, in limited cases, validity challenges. Key steps include reviewing all testamentary documents, seeking specialist advice, considering a caveat, and pursuing mediation or court claims if necessary. Understanding these options helps individuals protect their interests and navigate the legal framework governing partial intestacy.
