Understanding Trusts and Their Purpose

A trust is a legal arrangement where one or more individuals (trustees) manage assets for the benefit of another person or group (beneficiaries). Trusts are commonly used in estate planning to:

• Protect assets for minors or vulnerable individuals
• Minimise inheritance tax
• Control the timing and distribution of wealth
• Shield assets from creditors or care home fees

While trusts can simplify inheritance, conflicts can arise when parties feel they’ve been treated unfairly, left out, or that the trust was established under suspicious circumstances.

Can a Trust Be Contested? Yes—Here’s When

Contesting a trust means legally challenging its validity, terms, or administration. While courts generally uphold legally sound trusts, they will investigate and possibly overturn a trust if any of the following grounds apply:

1. Lack of Capacity

If the person who set up the trust (known as the settlor) lacked mental capacity at the time of creating the trust, it could be challenged. This is especially relevant if the settlor suffered from dementia or another cognitive impairment. Medical evidence may be required.

2. Undue Influence or Coercion

Trusts must be created freely. If there’s evidence that the settlor was pressured or manipulated into creating or altering a trust, it could be deemed invalid. This is a common claim when one beneficiary appears to benefit disproportionately.

3. Fraud or Forgery

If the trust document contains forged signatures or was created based on deceit, it can be contested. This includes scenarios where someone misrepresents facts to get themselves added as a beneficiary or trustee.

4. Mistake in the Trust Document

A drafting error can also be grounds for contesting a trust. If the language doesn’t reflect the settlor’s true intentions, a court may be asked to rectify the mistake or modify the trust accordingly.

5. Breach of Trustee Duties

If trustees mismanage assets or act in their own interests instead of in the best interests of beneficiaries, legal action can be taken. This is not about the trust’s creation but about how it’s administered.

Trusts can be challenged in several ways, but it’s crucial to act quickly and seek legal advice early.

Who Can Contest a Trust?

The right to contest a trust usually belongs to those with a “legal interest” in it. This typically includes:

• Beneficiaries named in the trust
• Heirs or family members who expected to benefit but were excluded
• Creditors, in some cases

Courts will assess the relationship of the challenger to the settlor and the trust itself before agreeing to hear the claim.

Time Limits: How Long Do You Have to Contest?

Deadlines matter. If you want to contest a trust, timing depends on the nature of your claim:

• For fraud or undue influence, there’s no strict time limit, but acting quickly is advised
• For mistake or rectification, claims must be made within 6 years
• For breach of trust, the time limit is typically 6 years from when the breach occurred

Always consult a solicitor as early as possible to protect your rights and preserve the evidence.

Contesting a Trust vs Contesting a Will

While they serve similar purposes, contesting a trust is not the same as contesting a will. A trust can take effect during a person’s lifetime (called a lifetime or “inter vivos” trust), whereas a will takes effect after death.

If a trust is set up to distribute assets outside the will, it may be harder to challenge—especially if done years earlier. However, a poorly constructed or suspicious trust may still be vulnerable to legal scrutiny.

What Happens If a Trust Is Successfully Contested?

If a court finds the trust invalid, it may:

• Revoke the trust entirely
• Modify certain terms
• Remove or replace trustees
• Redistribute assets more fairly

This can have significant tax and inheritance implications, so it’s essential to get expert legal support when pursuing or defending a trust challenge.

Can a Trust Be Contested by Siblings or Stepchildren?

Yes, family members such as siblings, children, or stepchildren can contest a trust if they believe:

• They were unfairly excluded
• They were promised inclusion and later omitted
• The settlor was unduly influenced by another party

These disputes are often emotionally charged and can lead to long court battles if not handled properly. Mediation is sometimes a better path for resolving family trust disputes amicably.

How to Minimise the Risk of a Contested Trust

If you’re creating a trust, here are some steps to minimise the chance it will be contested:

• Work with a qualified estate planner or solicitor
• Document your reasons clearly (especially if you’re excluding anyone)
• Get a medical capacity assessment if there’s any doubt
• Appoint neutral trustees who understand their duties

FAQs: Contesting a Trust in the UK

Can a trust be overturned in the UK?

Yes. A trust can be overturned if it’s proven to be created under duress, fraud, or mental incapacity, or if the trustees breach their duties.

How do I start contesting a trust?

Seek legal advice immediately. A solicitor will help you review the trust document, gather evidence, and file the appropriate claim in court.

Can beneficiaries change the terms of a trust?

Not usually. Only the settlor can change the trust—unless all beneficiaries agree, and the trust allows for modification.

Can a trust be contested after the settlor’s death?

Yes, though it may be harder to gather evidence. You can still challenge based on the original trust creation or trustee behaviour.
