Will Trust Document Review: Ensure Legal Compliance

Why will and probate paperwork must be precise

A will trust isn’t just a set of instructions—it’s the legal backbone that decides who gets what, when, and how much tax they’ll pay. For families with young children, blended households, or assets over the £325,000 inheritance tax threshold, a poorly drafted will trust can turn a straightforward estate into a costly, drawn-out dispute. Many people assume their solicitor’s original draft is watertight, but laws change, family circumstances shift, and small oversights—like an outdated bereaved minor trust or a missing discretionary clause—can lead to unintended beneficiaries, higher tax bills, or even court battles.

Discretionary trusts, for example, give trustees flexibility to distribute assets, but if the wording is vague, HMRC may challenge the tax treatment. Bereaved minor trusts, designed to protect assets for children under 18, must comply with strict rules under the Inheritance Tax Act 1984 (IHTA1984); a single misworded clause could disqualify the trust from tax relief. And with inheritance tax receipts hitting record highs—HMRC collected £7.5 billion in 2023/24—even a minor drafting error can cost thousands in avoidable tax.

This isn’t just about avoiding mistakes; it’s about ensuring your will trust does exactly what you intend. A compliance and gap review doesn’t rewrite your document—it flags risks, clarifies ambiguities, and gives you the confidence that your estate plan is fit for purpose.

Is this wills or probate document in usable shape?

A well-drafted will trust document should be clear, compliant, and tailored to your goals—whether that’s protecting assets for minor children, minimising tax, or giving trustees flexibility. "Good shape" means no vague clauses, no outdated references to repealed laws, and no gaps that could trigger disputes or extra tax. If your document hasn’t been reviewed since the last major tax change (like the 2020 increase in the residence nil-rate band), it’s likely due for a check.

Wills, probate and succession rules in plain English

Two key laws shape how will trusts work in England and Wales: the Administration of Estates Act 1925 (AEA1925) and the Inheritance Tax Act 1984 (IHTA1984).

The AEA1925 sets out the basic rules for how estates are administered after someone dies. It covers who can act as an executor, how debts are paid, and how assets are distributed. For will trusts, it’s particularly important because it defines how trustees take control of assets and what powers they have. If your trust document doesn’t align with these rules—say, by giving trustees powers that conflict with the Act—it could cause delays or legal challenges.

The IHTA1984 is the main law governing inheritance tax. It sets the thresholds, reliefs, and rules for how trusts are taxed. For example, it explains how bereaved minor trusts can qualify for special tax treatment, or how discretionary trusts are taxed at different rates. If your trust doesn’t meet the IHTA1984’s requirements—like missing a key clause for a bereaved minor trust—HMRC may treat it as a standard trust, leading to higher tax bills.

These laws don’t just apply to high-net-worth individuals. Even modest estates can be affected if the trust isn’t structured correctly. For instance, a discretionary trust with unclear terms might be taxed at 6% every 10 years under the "relevant property regime," while a properly drafted bereaved minor trust could avoid this entirely.

Five wills & probate checks before you act

1. Discretionary trust wording: Is it flexible enough—or too vague?

Discretionary trusts let trustees decide how and when to distribute assets, which is useful for families with complex needs (e.g., beneficiaries with disabilities or spendthrift tendencies). But if the wording is too broad, HMRC may argue the trust doesn’t qualify for favourable tax treatment. Conversely, if it’s too restrictive, trustees might lack the flexibility to adapt to changing circumstances.

What to look for:

• Does the document define the "class of beneficiaries" clearly? (e.g., "my children and grandchildren" vs. "any person I have ever known")
• Are there any restrictions on how trustees can distribute assets? (e.g., "must distribute equally" vs. "may distribute as they see fit")
• Does it include a "letter of wishes" to guide trustees, or is the trust entirely open-ended?

Practical tip: If your trust is purely discretionary, include a non-binding letter of wishes to explain your intentions. This won’t bind the trustees, but it can help them make decisions that align with your goals.

VetroCheck check: Our review flags ambiguous beneficiary classes and missing guidance clauses, so you can clarify the trust’s purpose without rewriting it.

2. Bereaved minor trust: Does it meet the IHTA1984 rules?

Bereaved minor trusts (BMTs) are designed for children under 18 who lose a parent. They offer tax advantages, like avoiding the 6% "relevant property" charge, but only if they meet strict IHTA1984 conditions. Common pitfalls include:

• The trust not being set up by a parent (e.g., a grandparent’s trust won’t qualify).
• The child not becoming absolutely entitled to the assets by age 18.
• The trust allowing distributions to anyone other than the child before they turn 18.

What to look for:

• Does the document state that the trust is for a bereaved minor (i.e., a child under 18 who has lost a parent)?
• Does it specify that the child becomes absolutely entitled to the assets at 18?
• Are there any clauses allowing distributions to other beneficiaries (e.g., siblings) before the child turns 18?

Practical tip: If your trust includes a bereaved minor, double-check that it doesn’t allow early distributions to anyone else. Even a small clause—like "trustees may pay income to the child’s siblings"—could disqualify the trust from tax relief.

VetroCheck check: We verify whether your BMT meets the IHTA1984 criteria and flag any clauses that could jeopardise its tax status.

3. Tax clauses: Are you missing reliefs or triggering extra charges?

Tax clauses determine how your trust is treated under the IHTA1984. Common issues include:

• Missing the "nil-rate band" clause, which could lead to unnecessary tax.
• Failing to specify whether the trust is "interest in possession" or "discretionary," which affects tax rates.
• Not accounting for the residence nil-rate band (RNRB), which can add up to £175,000 in tax-free allowance for homes passed to direct descendants.

What to look for:

• Does the document mention the nil-rate band (currently £325,000)?
• Does it specify whether the trust is discretionary or interest in possession?
• If the trust includes a home, does it reference the RNRB?

Practical tip: If your estate includes a property, ensure the trust document references the RNRB. Without it, you could miss out on £175,000 of tax-free allowance.

VetroCheck check: Our review identifies missing tax reliefs and flags clauses that could trigger higher charges, so you can discuss fixes with your solicitor.

4. Trustee powers: Do they have the tools they need?

Trustees need clear powers to manage the trust effectively. Common gaps include:

• No power to invest assets (which could limit growth).
• No power to pay for beneficiaries’ education or maintenance (which could cause hardship).
• No power to appoint new trustees (which could leave the trust stranded if a trustee dies or becomes incapacitated).

What to look for:

• Does the document list specific powers (e.g., "invest in stocks and shares") or rely on generic wording?
• Are there any restrictions on how trustees can use income or capital?
• Does it include a "default clause" for what happens if a trustee can’t act?

Practical tip: If your trust is for minor children, ensure trustees have explicit powers to pay for education, healthcare, or housing. Without these, they may need court approval for basic expenses.

VetroCheck check: We highlight missing trustee powers and suggest additions to ensure the trust can function smoothly.

5. Contingency clauses: What if the unexpected happens?

Life doesn’t always go to plan. Contingency clauses cover scenarios like:

• A beneficiary dying before the trust takes effect.
• A trustee becoming incapacitated or unwilling to act.
• The trust’s assets being insufficient to cover all distributions.

What to look for:

• Does the document include a "survivorship clause" (e.g., "beneficiaries must survive me by 30 days")?
• Are there backup trustees named?
• Does it specify what happens if a beneficiary can’t be found or refuses the inheritance?

Practical tip: Include a survivorship clause to avoid assets passing to unintended beneficiaries (e.g., if a child dies shortly after you, their share could go to their spouse instead of your other children).

VetroCheck check: Our review flags missing contingency clauses and suggests ways to future-proof your trust.

Estate mistakes that create family disputes and delay

1. Assuming "standard" clauses are enough

Many will trusts use template language from outdated precedents. For example, a discretionary trust might include a generic "power to invest" clause that doesn’t cover modern assets like cryptocurrency or online accounts. If trustees can’t access or manage these assets, the trust could lose value—or face legal challenges from beneficiaries.

Consequence: Delays in distributing assets, potential disputes, or lost value from unmanaged investments.

---

2. Overlooking the residence nil-rate band (RNRB)

The RNRB (£175,000 per person) can save up to £70,000 in inheritance tax for a married couple passing a home to children. But it only applies if the trust document explicitly references it. Many older wills don’t include this clause, meaning families miss out on the relief.

Consequence: Unnecessary tax bills of up to £70,000 for a married couple.

---

3. Miswording bereaved minor trusts

A bereaved minor trust must meet strict IHTA1984 rules to qualify for tax relief. A common mistake is allowing trustees to distribute income to anyone other than the child before they turn 18. Even a small clause—like "trustees may pay income to the child’s siblings"—can disqualify the trust from tax advantages.

Consequence: The trust is taxed as a discretionary trust, triggering a 6% charge every 10 years.

FAQ

What does the Will Trust Document Review: compliance and gap review review?

The review is an information-only audit of your will trust document, focusing on three key areas: discretionary trusts, bereaved minor trusts, and tax clauses. It checks whether your document complies with the Administration of Estates Act 1925 (AEA1925) and the Inheritance Tax Act 1984 (IHTA1984), and flags gaps that could lead to disputes, higher tax, or unintended distributions.

Which legal sources are used in the review?

The analysis is based on the AEA1925, IHTA1984, and other relevant UK legal sources. We don’t rely on case law or solicitor interpretations—just the statutes that govern how will trusts work in England and Wales.

Which specific points are checked?

The review covers:

• Discretionary trusts: Clarity of beneficiary classes, trustee powers, and tax treatment.
• Bereaved minor trusts: Compliance with IHTA1984 rules, including age limits and distribution restrictions.
• Tax clauses: Nil-rate band, residence nil-rate band (RNRB), and trust type (discretionary vs. interest in possession).
• Trustee powers: Investment, distribution, and appointment authorities.
• Contingency clauses: Survivorship, backup trustees, and asset insufficiency.

Each finding is backed by a citation from your document, so you can see exactly where the issues lie.
