How to Challenge a Will With Life Interests

A life interest in the context of wills and estates is a common legal arrangement in England and Wales that allows a beneficiary to benefit from an asset during their lifetime without owning it outright. Life interests are typically created through life interest trusts in wills, often referred to as interests in possession, and give a beneficiary (the “life tenant”) the right to enjoy income or use of the asset during their lifetime, with the capital passing to someone else (the “remainderman”) after their death. 

Challenging a will that includes a life interest provision can be legally and practically complex. Life interests can affect inheritance patterns, financial provision for dependants and the ultimate distribution of capital. Disputes arise when beneficiaries or potential claimants consider a life interest unfair, insufficient, or contrary to the deceased's true intentions. This article outlines how life interests operate, the legal rights and mechanisms for challenging them, the processes involved, time limits, risks and frequently asked questions.

What Is a Life Interest and How Does It Arise?

A life interest - also known as an interest in possession - is a type of legal provision commonly created in a will. Under a life interest trust, assets are placed into a trust on the testator's death and a named beneficiary (the life tenant) has the right to:

• Receive income from those assets (for example rent from property or dividends from investments), and/or
• Use or occupy property held in the trust for their lifetime. 

The underlying capital - the trust assets themselves - are preserved for the ultimate beneficiaries (remaindermen) after the life tenant's death or on another defined event. Typical scenarios include granting a surviving spouse the right to live in the family home for life, with the property then passing to children or grandchildren. 

Life interests are often used in estate planning to balance financial support for a spouse with safeguarding inheritance for other beneficiaries, such as children from a previous relationship. 

Why Life Interests Can Lead to Will Challenges

Life interests affect estate distribution in ways that may be contentious among beneficiaries or potential claimants. Challenges can arise where:

• The life interest granted is insufficient to provide reasonable financial support. 
• The terms of the life interest are ambiguous or unclear in the will.
• Beneficiaries believe the testator lacked capacity, was unduly influenced, or did not understand the effect of the trust provisions in the will.
• Life interest provisions marginalise potential claimants who may instead seek different forms of inheritance.
• Strategic estate planning (e.g. tax or care planning) has distorted the substantive benefit to a life tenant relative to other beneficiaries.

A life interest itself is simply a legal “interest in possession.” It is a recognised form of provision. However, how it interacts with claims under the Inheritance (Provision for Family and Dependants) Act 1975 (the “1975 Act”) and general contest provisions can significantly affect whether a challenge succeeds. 

Legal Grounds for Challenging a Will With Life Interests

1. Validity Challenges

Challenges to the validity of any will, including those containing life interests, are based on established legal principles. Under English law, a will may be challenged if the claimant can establish one or more of the following:

• Lack of testamentary capacity: The testator did not have the mental capacity to understand the nature and effect of the will when drafted.
• Lack of knowledge and approval: The testator did not know or approve the contents of the will or the life interest provisions.
• Undue influence or duress: The testator was pressured or coerced by another person into creating the life interest or other parts of the will.
• Improper execution: The will was not signed and witnessed in accordance with the formal statutory requirements.
• Fraud or forgery: The document or signatures are forged or fraudulent. 

If a will is declared invalid on one of these grounds, it may be treated as never having existed, which could result in an earlier will taking effect or distribution under the intestacy rules.

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

The 1975 Act allows certain individuals to apply to the court if a will, even if valid, fails to make reasonable financial provision for them. Reasonable financial provision is assessed objectively based on the claimant's financial position, needs and relationship to the deceased. 

In the context of life interests:

• A life interest may constitute financial provision, but whether it is reasonable depends on its value and whether it meets the claimant's needs.
• A life interest that provides little or no income, or leaves the claimant without capital while others receive significant capital entitlements, may be insufficient provision in certain cases. 
• Courts may award different forms of provision - including life interests, lump sums, income rights or transfer of assets - if they find the life interest alone is inadequate.

Decisions such as Banfield v Campbell [2018] EWHC 1943 (Ch) have shown that courts may favour life interests over lump sums in circumstances where it better reflects the claimant's needs and the testator's intentions. 

Practical Steps in Challenging a Will With a Life Interest

Step 1: Establish Your Standing and Grounds

You must first determine whether you have legal standing to challenge the will or bring a statutory claim. Eligible claimants typically include:

• Spouses or civil partners.
• Children or dependants.
• Those who would inherit under a previous will or under intestacy.
• Individuals who can show they were entitled to reasonable provision but have been inadequately provided for.

Understanding the nature and value of the life interest, and whether it meets the claimant's needs, informs the best legal approach.

Step 2: Review the Will and Trust Terms

Analyse the wording of the will, including the life interest trust provisions. Note whether:

• The life interest is clearly defined (e.g. income only or right to occupancy).
• Event triggers apply (e.g. remarriage or moving to care).
• Trustees have specific powers relating to the trust assets.

A precise interpretation of trust terms is often critical in determining how a challenge might succeed.

Step 3: Gather Evidence

Evidence is central to any challenge. Key materials may include:

• The original will and any variations or earlier versions.
• Medical or capacity evidence relating to the testator at the time the will was made.
• Correspondence or other documents indicating the testator's intentions.
• Financial details showing the value of the life interest compared to the claimant's needs.

Step 4: Preserve Your Position

If probate has not yet been granted, consider lodging a caveat with the Probate Registry to halt distribution while you prepare a challenge. Once probate is granted, the time limits for statutory claims begin to run. 

Step 5: Seek Legal Advice and Consider Settlement

Engage a solicitor with experience in contentious probate. Many disputes are settled through negotiation or mediation before court proceedings. Inheritance disputes involving life interests can often be resolved without full litigation.

Step 6: Initiate Court Proceedings if Necessary

If negotiation fails, you may issue court proceedings. Challenges can be commenced either:

• In the High Court (Chancery Division) for validity issues or trust disputes.
• Through the Probate Registry for Inheritance Act claims.

The court will assess your claims based on evidence and legal tests.

Time Limits and Procedural Considerations

• Claims under the Inheritance Act 1975 must generally be brought within six months of the date of the Grant of Probate or Letters of Administration. 
• There is no fixed statutory deadline for some validity challenges (e.g. lack of capacity), but procedural delays weaken evidence and may make it harder to reverse estate distributions.
• A caveat can temporarily delay probate to allow time to investigate potential challenges. 

Prompt action preserves evidence, strengthens your position and avoids missed opportunities.

Risks and Considerations

Challenging a will that includes a life interest carries practical and legal risks:

• Adverse costs: If your claim fails, you may be ordered to pay your own and other parties' legal costs.
• Family relationships: Disputes may strain relationships, especially where life interests were intended to balance competing needs.
• Complex valuation: Life interests require valuation of income streams and capital distributions, potentially involving expert evidence.
• Trust administration: Life interest trusts may continue for many years, making timing and financial planning complex.

Understanding these risks with specialist advice is essential for informed decision‑making.

Common Questions from our Readers

Can I challenge a life interest itself?
A life interest can be challenged indirectly if it can be shown that the will fails to make reasonable financial provision under the 1975 Act or that the will is invalid on other legal grounds. 

Is a life interest always reasonable provision?
Not necessarily. The courts assess whether a life interest provides sufficient financial support and whether additional provision is necessary based on the claimant's needs and relationship with the deceased. 

Can a no-contest clause prevent a challenge?
No‑contest clauses can discourage challenges, but they do not automatically prevent statutory claims under the 1975 Act. Their effect is assessed in context; they may influence the court's view of reasonableness but cannot override statutory rights. 

Key Takeaways

A life interest provision in a will - through a life interest trust or interest in possession - is a recognised way to provide for a beneficiary while preserving capital for others. Challenging a will that includes such provisions depends on whether the will is valid, whether reasonable financial provision has been made, and whether the claimant is legally entitled to improve their position. Challenges require clear legal grounds, careful evidence gathering, timely action and often specialist legal advice. Life interest disputes intersect with trust, inheritance and probate law, making understanding each legal element essential to navigating these claims effectively.
