What is Undue Influence?
Undue influence refers to a situation where one party exerts pressure or influence over another party to enter into a contract or make a decision against their own free will. This pressure could be psychological, emotional, or financial in nature, and it essentially deprives the influenced party of their ability to make independent and voluntary decisions.
How it differs from duress: Duress involves overt threats of physical harm or unlawful action, whereas undue influence is subtler and arises from the manipulation or exploitation of a relationship of trust rather than direct threats.
The Two Types of Undue Influence
Presumed undue influence and actual undue influence are two legal concepts that pertain to situations where one party exerts an improper level of control or influence over another, leading to a transaction that is considered unfair or invalid.
Both are legal constructs designed to protect individuals from unfair or coercive transactions, ensuring that their autonomy and rights are upheld in legal proceedings.
Actual Undue Influence
This occurs when one party exerts such pressure or influence on another party that it overpowers the free will of the influenced party. The influenced party's consent is thus not truly voluntary.
Presumed Undue Influence
This type arises in certain relationships where one party is in a position of trust and confidence over the other party. In such cases, the law presumes that influence has been exerted, and it is up to the party in the position of power to prove that the transaction was fair, just, and entered into willingly by the other party.
Presumed undue influence is often categorised into 2A and 2B:
- Class 2A (Automatic Presumption): Relationships of recognised trust and confidence (e.g. parent/child, solicitor/client, doctor/patient, trustee/beneficiary).
- Class 2B (Proved Relationship): No automatic presumption, but the claimant shows an actual relationship of trust and confidence, so the burden still shifts.
If the stronger party cannot rebut the presumption (e.g. by showing independent advice was taken), the court may set aside the transaction.
Comparing Actual and Presumed Undue Influence
| Feature | Actual Undue Influence | Presumed Undue Influence |
| Evidence | Claimant must prove direct coercion or manipulation | Law presumes influence from certain relationships or facts |
| Burden of Proof | On the claimant | Shifts to the alleged influencer to show fairness/voluntariness |
| Examples | Threatening to withdraw care unless the will is changed | Solicitor receives a gift from a client without independent advice |
| Effect | Contract/will be voidable if proven | Contract/will be voidable unless presumption rebutted |
The Elements of Presumed Undue Influence
In cases of presumed undue influence, the following elements are typically considered:
- Relationship of Influence: There must exist a relationship of trust and confidence between the parties involved. This can include relationships such as parent and child, solicitor and client, doctor and patient, guardian and ward, or trustee and beneficiary.
- Influence Arising from the Relationship: The nature of the relationship must create a presumption that one party is in a position to exert influence over the other. The courts recognise that certain relationships inherently involve a higher degree of trust, reliance, and vulnerability on the part of one party, which can give rise to the presumption of influence.
- Unfair Transaction: The transaction in question must be shown to be unjust or unconscionable. This could mean that the influenced party received inadequate consideration, made a gift without proper understanding, or entered a transaction that was not in their best interests.
When the above elements are satisfied, the burden shifts to the influencer to prove that the transaction was fair, reasonable, and entered voluntarily by the influenced party. If the influencer fails to rebut the presumption of undue influence, the transaction may be deemed voidable or set aside by the court.
It’s important to consult with a qualified solicitor or legal professional for specific advice on presumed undue influence as it applies to your particular situation, as laws can vary and legal principles can evolve.
The Burden of Presumed Undue Influence
The notion of presumed undue influence places a burden of proof on certain parties involved in transactions where there exists a relationship of trust and confidence. This burden typically falls upon the party that benefits from the transaction or holds the position of power in the relationship.
When a transaction occurs between parties in a relationship where one party is in a position of trust and influence over the other, such as a parent-child relationship, a solicitor-client relationship, or a doctor-patient relationship, the law presumes that undue influence may have been exerted. This presumption arises due to the inherent vulnerability of the party in the weaker position, which may be susceptible to the influence of the stronger party.
The Burden of Proof
The burden of proof shifts to the party in the stronger position to demonstrate that the transaction was fair, just, and entered into willingly by the weaker party. This means that the party benefiting from the transaction must show that there was no undue pressure or improper influence exerted to secure the agreement.
To meet this, the party in the stronger position may need to provide evidence that the transaction was entered into voluntarily, with full understanding and consent from the weaker party. This could involve demonstrating that independent legal advice was sought and obtained, that there was transparency and disclosure of all relevant information, and that the terms of the transaction were fair and reasonable.
Failure to rebut the presumption of undue influence can result in the transaction being set aside by the court, rendering it voidable. This means that the weaker party may have the option to rescind the transaction and seek redress for any losses suffered as a result of the undue influence.
The Consequences of Undue Influence
Depending on the area of law in which undue influence occurs, the consequences can include:
- Contracts Deem Void: Contracts entered into under undue influence are not automatically void but are voidable at the option of the victim. This means that the victim has the right to choose whether to affirm or rescind the contract.
- Rescission of Contracts: If a contract is found to be influenced by undue pressure, the victim can seek to have the contract set aside (rescinded). This effectively nullifies the contract and restores the parties to their pre-contractual positions.
- Legal Remedies: The victim may be entitled to legal remedies such as damages or restitution to compensate for any losses suffered as a result of the undue influence. This could include financial compensation for any undue pressure exerted.
- Criminal Consequences: In cases where undue influence amounts to fraud or other criminal conduct, the perpetrator may face criminal charges and penalties under the law.
- Equitable Remedies: Courts may also grant equitable remedies such as injunctions or specific performance to prevent further harm or to enforce fairness in the situation.
- Voiding of Gifts: Undue influence can also impact gifts made by the victim. If a gift is found to be the result of undue influence, it may be set aside or declared void.
- Loss of Reputation and Trust: Perpetrators of undue influence may suffer damage to their reputation and trustworthiness, particularly if their actions are publicised or result in legal consequences.
The Remedies of Undue Influence
When a court finds that a contract, gift or will has been obtained through undue influence, it can intervene to undo the unfair result. The key remedies are:
- Rescission (Setting Aside the Transaction):
The most common remedy. The contract, gift or transfer is cancelled and the parties are restored, as far as possible, to their original positions. - Restitution or Repayment: Money, property or benefits wrongly obtained can be returned, and compensation awarded for losses caused by the undue influence.
- Invalidation of a Will or Gift: If a will is proved to be the product of undue influence, the court disregards it and either reinstates an earlier valid will or applies the intestacy rules. Gifts made under undue influence can also be declared void.
- Equitable Orders: Courts can grant injunctions or other equitable remedies to prevent further harm or to enforce fair dealing, for example, stopping a transfer from going ahead until independent advice is taken.
- Independent Advice as a Preventive Measure: Even before a dispute reaches court, transactions can often be “rescued” by ensuring the weaker party receives proper, independent legal advice. This is a key protection highlighted in Royal Bank of Scotland v Etridge (No 2).
These remedies aim to restore the victim’s autonomy and undo the advantage gained by the influencer, ensuring fairness in both commercial and personal contexts.
Understanding Undue Influence
To prove undue influence, it's typically necessary to demonstrate a relationship of trust and confidence between the parties involved and that one party abused that relationship to unfairly benefit themselves at the expense of the other party.
Examples in Different Contexts
These examples illustrate situations where one party takes advantage of their power, authority, or influence to exploit the vulnerability or dependency of another party, leading to unfair outcomes in legal transactions or decisions.
- Contract Law: A wealthy businessperson pressures a financially struggling individual to sign a contract for the sale of their property at a significantly lower price than its market value by exploiting their desperation.
- Family Law: An elderly parent, dependent on their adult child for care, is coerced into changing their will to favour that child over other family members, under the threat of being placed in a care home against their wishes.
- Employment Law: An employer threatens an employee with termination if they do not sign a contract amendment that significantly reduces their benefits, despite knowing the employee's financial reliance on the job.
- Property Law: A landlord uses their position of authority over a tenant to manipulate them into signing a lease agreement that contains unfair terms, such as extortionate rent increases or excessive repair responsibilities.
- Commercial Law: A dominant shareholder in a company pressures minority shareholders into voting in favour of a merger proposal that benefits the dominant shareholder financially but is detrimental to the interests of the minority shareholders.
Undue Influence in Contract Law
Undue influence occurs when one party exerts improper pressure on another, undermining their free will and leading them to enter into a contract they would not have otherwise agreed to. If proven, undue influence can render a contract voidable, meaning the influenced party may choose to set it aside.
Relevance in Financial Transactions
Undue influence frequently arises in contexts involving loans, mortgages, and guarantees, particularly when a vulnerable party is persuaded to sign documents benefiting another (e.g. a spouse or child). Lenders are especially cautious in such cases, as failure to ensure the absence of undue influence can invalidate security agreements.
How Courts Decide
The burden of proof initially lies on the claimant to show a relationship of trust and a transaction that calls for explanation. If established, a presumption of undue influence may arise. The other party must then rebut this presumption, typically by proving the transaction was entered into freely, often with evidence of independent legal advice.
Undue Influence in Wills
Proving undue influence in wills is significantly more challenging than in contract law. The courts require clear evidence that the testator was coerced into making a will (or a specific bequest) against their true wishes.
Vulnerable Testators
Common scenarios include elderly or ill individuals being pressured by relatives or carers. While influence alone is not enough, the key test is whether the conduct overpowered the testator’s free will.
- Craig v Lamoureux: Emphasised the need for direct evidence of coercion rather than mere suspicion.
- Edwards v Edwards [2007]: Reiterated that undue influence in wills must be proven to a high standard and cannot be presumed.
Importance of Evidence
Medical records, solicitor notes, and witness testimony are often crucial. A well-documented will prepared with professional advice significantly reduces the risk of successful undue influence claims.

FAQ
What is undue influence in UK law?
Undue influence in UK law occurs when someone misuses a position of trust or power to pressure another person into a decision they wouldn’t otherwise make freely. It can apply to contracts, wills, gifts and other legal transactions, and may render them open to challenge.
What is the difference between actual and presumed undue influence?
- Actual undue influence must be proved with direct evidence of pressure, coercion or manipulation that overrode the victim’s free will.
- Presumed undue influence arises automatically in certain relationships of trust (for example, solicitor-client or parent-child). In these cases, the law assumes influence was exerted, and the burden shifts to the stronger party to show the decision was fair and voluntary.
What are examples of undue influence in wills?
Examples include:
- A carer or relative is threatening to withdraw care unless named as a major beneficiary.
- Pressuring an elderly or vulnerable testator to make sudden, significant changes to a long-standing will.
- Arranging the will-writing process so the testator has no private discussion with the solicitor or no chance to obtain independent advice.
Is undue influence hard to prove?
Yes, particularly with wills, courts require strong, clear evidence that the testator’s free will was overborne by coercion or manipulation. Mere persuasion or influence is not enough.
What happens if undue influence is proven in a will or contract?
If a contract, gift or will is found to be the product of undue influence, it becomes voidable:
- Contracts/Gifts: May be rescinded (set aside) and the parties restored to their previous position.
- Wills: The invalid will is disregarded, and an earlier valid will or the intestacy rules apply instead.
What does undue influence mean in the context of UK law?
Undue influence refers to a situation where one party misuses their position of power or trust to manipulate another party, undermining their ability to make an independent decision. It can render a contract, will, or transaction voidable.
What is undue influence in the context of contract law?
In contract law, undue influence occurs when one party exerts improper control or coercion over another, undermining their free will and compromising their ability to make an independent decision. It involves demonstrating direct evidence of the influencer’s undue pressure or manipulation.
