When dealing with wills and inheritance, the concept of undue influence often arises as a critical factor. It can dramatically affect the validity of a will and the distribution of an estate. Understanding how undue influence operates in legal contexts is essential if you find yourself navigating a will dispute. This post will guide you through the key aspects of undue influence, including clear legal undue influence examples, the burden of proof, and practical steps to protect your interests.
Understanding Legal Undue Influence Examples
Undue influence occurs when someone exerts excessive pressure on a testator - the person making the will - to alter their testamentary intentions. This pressure compromises the testator’s free will, leading to a will that may not reflect their true wishes. But what exactly does undue influence look like in practice?
Legal undue influence examples often involve a close relationship where one party holds significant power over the testator. For instance:
A caregiver who isolates the testator from family members and persuades them to change their will in the caregiver’s favour.
A family member who exploits the testator’s vulnerability due to illness or age to secure a larger inheritance.
A trusted advisor who manipulates the testator into making decisions that benefit the advisor financially.
These examples highlight the subtle and sometimes overt ways undue influence can manifest. It is not always about threats or force; psychological pressure and manipulation can be just as effective in swaying a testator’s decisions.

Recognising these signs early can help you challenge a will that may have been created under undue influence. If you suspect such interference, consulting with legal experts who specialise in will disputes is crucial. They can assess the situation and advise on the best course of action.
What is the burden of proof for undue influence?
In cases involving undue influence, the burden of proof lies with the person challenging the will. This means you must provide convincing evidence that the testator’s free will was compromised. The courts do not assume undue influence lightly, as wills are presumed valid unless proven otherwise.
To meet this burden, you will need to demonstrate:
A relationship of trust and confidence between the testator and the alleged influencer.
Suspicious circumstances surrounding the creation or alteration of the will.
Evidence of the influencer’s opportunity and motive to exert pressure.
A result that appears unnatural or unexpected, such as a significant change in the will favouring the influencer.
Gathering this evidence can be challenging. It may involve collecting witness statements, medical records, and correspondence that reveal the testator’s state of mind and the nature of their relationships.

Understanding the burden of proof helps you prepare a stronger case. It also emphasises the importance of acting promptly, as delays can result in lost evidence or weakened claims.
How undue influence cases affect the validity of a will
When undue influence is proven, the consequences for the will can be significant. The court will declare will to be invalid. This can lead to the estate being distributed according to a previous valid will or, if none exists, under the rules of intestacy.
The impact of undue influence cases extends beyond just the legal outcome. They often cause emotional distress and family rifts.
It is important to note that not every unusual or unexpected will change is due to undue influence. Sometimes, testators make genuine decisions based on changing circumstances or personal preferences. The court carefully weighs all evidence before reaching a verdict.

If you are involved in a dispute, seeking advice from specialists who understand the nuances of undue influence can help you navigate these complexities. They can guide you through mediation or court proceedings, aiming for a resolution that respects the testator’s true intentions.
Practical steps to protect yourself from undue influence in will disputes
If you are concerned about undue influence affecting a will, there are several practical steps you can take:
Encourage the testator to seek independent legal advice. This reduces the risk of manipulation and ensures the testator understands their decisions.
Document the testator’s wishes clearly. Written statements or video recordings can provide valuable evidence of their intentions.
Involve neutral witnesses during the will-making process. Their testimony can support the will’s validity.
Monitor the testator’s interactions. Be alert to signs of isolation or pressure from others.
Act quickly if you suspect undue influence. Early intervention can prevent further harm and preserve evidence.
By taking these measures, you can help safeguard the testator’s autonomy and reduce the likelihood of disputes.
