CIVIL LAW AND UNDUE INFLUENCE ON PERSONS

1. Meaning of Undue Influence on Persons

Undue influence occurs when one person uses a position of influence, trust, confidence, authority, dependence, or ascendancy to cause another person to enter into a transaction without exercising a genuinely free and independent judgment.

The doctrine is primarily an equitable doctrine. Its purpose is to prevent a person from taking unfair advantage of another person's dependence or trust.

The essential concern is therefore not merely:

“Did the person sign or agree?”

but:

“Was the person's decision freely and independently made, or was it improperly produced by another person's influence?”

Modern authority treats undue influence as a single equitable doctrine, with “actual” and “presumed” undue influence representing different methods of proving the same underlying wrong. Royal Bank of Scotland plc v Etridge (No 2) [2001] UKHL 44; Nature Resorts Ltd v First Citizens Bank Ltd [2022] UKPC 10.

2. Purpose of the Doctrine

The doctrine protects:

elderly persons;

persons with limited financial knowledge;

persons dependent upon caregivers;

beneficiaries;

clients;

patients;

religious followers;

family members;

financially dependent persons;

persons relying heavily upon professional advisers;

persons giving guarantees for another's debts;

persons transferring substantial property.

Its objective is not to prevent legitimate persuasion.

People are naturally influenced by:

spouses;

parents;

children;

friends;

lawyers;

financial advisers;

religious leaders;

doctors;

caregivers.

Influence becomes legally problematic where it is improperly used to obtain a transaction or advantage.

3. Essential Elements

A typical undue influence claim requires examination of:

1. Relationship of influence

Did one person possess significant influence over another?

2. Improper use of influence

Was that influence abused?

3. Causation

Did the influence cause the transaction?

4. Transaction requiring explanation

Is the transaction unusual in the context of the relationship?

5. Free and independent judgment

Did the claimant genuinely exercise independent judgment?

6. Third-party involvement

If another person or institution is involved, did that third party know or have reason to inquire?

4. Undue Influence Is Not the Same as Ordinary Influence

A person can influence another without committing any legal wrong.

For example:

A son recommends that his father invest in a particular business. The father considers the advice, obtains independent financial advice and voluntarily invests.

That is ordinary influence.

By contrast:

A son deliberately isolates his elderly father, controls his financial information and pressures him to transfer his house to the son.

That may raise a serious undue influence issue.

The critical distinction is:

Influence + free choice = generally lawful

Improper influence + compromised free choice = potential undue influence

5. Actual Undue Influence

Actual undue influence is established through direct evidence of improper influence.

The claimant seeks to demonstrate what actually happened.

Evidence may include:

threats;

persistent pressure;

manipulation;

deception;

exploitation of emotional dependence;

deliberate isolation;

abuse of authority;

controlling access to information;

pressure during illness;

financial manipulation.

The modern authorities emphasise that actual undue influence concerns conduct which causes the claimant not to exercise a free and independent judgment.

6. Example of Actual Undue Influence

Suppose A is an elderly person's caregiver.

The caregiver tells A:

“If you do not transfer your property to me, I will stop looking after you.”

A becomes frightened and signs a transfer.

The claimant may attempt to establish:

the caregiver exercised influence;

the pressure was improper;

the pressure caused the transfer;

A did not exercise genuinely independent judgment.

The claim would be based primarily on direct proof of the influence.

7. Presumed Undue Influence

Presumed undue influence is an evidential route rather than a separate type of wrongdoing.

The claimant may establish:

a relationship of influence; and

a transaction that is not readily explicable by ordinary motives.

If these requirements are established, a rebuttable presumption may arise.

The party seeking to uphold the transaction can then attempt to show that the claimant acted freely and independently.

This framework is confirmed by Etridge and later authorities.

8. Relationship of Influence

A relationship of influence can arise from many circumstances.

Examples include:

Professional relationships

solicitor and client;

financial adviser and client;

trustee and beneficiary.

Personal relationships

parent and child;

spouse and spouse;

caregiver and dependent person.

Medical relationships

doctor and patient.

Religious relationships

spiritual adviser and follower.

Commercial relationships

employer and dependent employee;

business adviser and vulnerable client.

The categories are not closed.

The central question is whether the circumstances establish a relationship in which one person has acquired significant influence over another.

The House of Lords in Etridge specifically rejected the idea that the doctrine should be confined to a rigid list of relationships.

9. Trust and Confidence

Trust and confidence are central concepts.

The court may ask:

Did A trust B?

Did A rely upon B?

Did A depend upon B for important decisions?

Did B advise A about financial affairs?

Did B manage A's property?

Did A reasonably expect B to protect A's interests?

Where trust and confidence is substantial, the risk of abuse of influence increases.

However:

A relationship of trust does not automatically prove undue influence.

The transaction and surrounding circumstances remain important.

10. Vulnerable Persons

The doctrine is particularly important where the claimant is vulnerable.

Vulnerability may arise because of:

advanced age;

physical illness;

cognitive limitations;

emotional distress;

bereavement;

financial dependence;

social isolation;

lack of education;

limited financial knowledge;

language difficulties;

dependence upon a caregiver;

dependence upon a family member.

However, vulnerability alone is not enough.

The claimant generally needs to connect the vulnerability with the influence and the transaction.

11. Elderly Persons

Transactions involving elderly persons receive careful scrutiny where circumstances suggest exploitation.

For example:

an elderly person transfers a home to a caregiver;

a relative obtains a substantial gift;

a trusted adviser becomes the beneficiary of a large transfer;

a person changes financial arrangements shortly before death.

The court does not assume that elderly persons lack capacity or independence.

Instead, it examines the actual circumstances.

This distinction is important:

Old age ≠ incapacity

and

old age ≠ undue influence

But advanced age combined with dependency and an unusual transaction may provide important evidence.

12. Persons with Illness or Dependency

A person's illness can increase susceptibility to influence.

For example, a person may depend upon another for:

medical care;

housing;

transportation;

medication;

financial management;

communication with others.

A person who controls these necessities may acquire considerable influence.

The court may therefore investigate whether the relationship was exploited to obtain an advantage.

13. Family Relationships

Family relationships require careful analysis.

The following do not automatically establish undue influence:

parent-child relationship;

husband-wife relationship;

sibling relationship;

grandparent-grandchild relationship.

The court examines whether there was actual dependence or influence.

A particularly significant example is a transaction where one spouse guarantees another spouse's business debts.

That situation led to important decisions such as:

Barclays Bank plc v O'Brien;

CIBC Mortgages plc v Pitt;

Royal Bank of Scotland plc v Etridge (No 2).

14. Professional Advisers

A professional adviser can occupy a position of substantial influence.

Examples include:

solicitor;

accountant;

financial adviser;

investment adviser;

trustee;

property adviser.

A client may reasonably depend upon the professional's expertise.

Where the professional personally benefits from the client's transaction, the circumstances can require careful examination.

Independent advice is particularly important.

15. Religious or Spiritual Relationships

Religious relationships have historically been important in undue influence cases.

The classic example is:

Allcard v Skinner (1887) 36 Ch D 145

The claimant belonged to a religious sisterhood and had made substantial gifts.

The case recognised the significance of the relationship between a religious superior and follower.

However, the case also illustrates that equity does not automatically invalidate every gift made in a religious relationship.

The court examines whether the transaction resulted from improper influence and whether equitable relief remains available.

16. Allcard v Skinner

Facts

Miss Allcard entered a religious sisterhood and made substantial transfers of property.

She subsequently challenged the gifts on the basis of undue influence.

Principle

The case established a foundational approach to presumed undue influence:

certain relationships naturally involve influence;

a substantial transaction may require explanation;

independent advice can be relevant;

the existence of influence is not itself enough;

equitable relief may be affected by delay and acquiescence.

It remains one of the leading historical authorities.

17. Huguenin v Baseley

Huguenin v Baseley

(1807) 14 Ves Jr 273

This is one of the classic foundations of the equitable doctrine.

The case demonstrates that equity examines the circumstances in which consent was obtained, rather than merely accepting formal consent as conclusive.

The principle is often expressed through the question:

How was the person's intention produced?

This remains central to the modern doctrine.

18. National Westminster Bank plc v Morgan

National Westminster Bank plc v Morgan

[1985] AC 686

This case concerned a transaction involving a bank and a married couple.

The House of Lords considered the requirements for presumed undue influence.

The case became particularly associated with the idea of a transaction being disadvantageous to the person alleging undue influence.

Later cases, particularly Etridge, refined the analysis and preferred the formulation that the transaction should be one not readily explicable by ordinary motives.

Importance

The case is useful for understanding:

relationships of trust;

transactions requiring explanation;

presumed undue influence;

the development of the modern doctrine.

19. Barclays Bank plc v O'Brien

Barclays Bank plc v O'Brien

[1994] 1 AC 180

This is a leading authority concerning undue influence involving a third-party lender.

Facts

Mrs O'Brien provided security over the matrimonial home for her husband's business borrowing.

The transaction was challenged in circumstances involving improper influence and misrepresentation.

Principle

The House of Lords considered when a bank or lender may be affected by wrongdoing between the borrower and the person providing security.

A lender may be put on inquiry where the circumstances indicate a substantial risk that the transaction was procured through undue influence.

Importance

The case established the foundation for the later Etridge framework.

20. CIBC Mortgages plc v Pitt

CIBC Mortgages plc v Pitt

[1994] 1 AC 200

This case is important for the distinction between actual and presumed undue influence.

Principle

Where actual undue influence is proved, the claimant does not have to establish an additional requirement of “manifest disadvantage.”

The focus is on:

improper influence;

causation;

the resulting transaction.

This is important because a claimant who proves actual wrongdoing is not required to satisfy the separate evidential conditions associated with presumed influence.

21. Credit Lyonnais Bank Nederland NV v Burch

Credit Lyonnais Bank Nederland NV v Burch

[1997] 1 All ER 144

Facts

Ms Burch was a relatively junior employee who provided security for her employer's indebtedness.

The bank was aware of circumstances suggesting that the transaction involved a significant imbalance and relationship of influence.

Principle

The case demonstrates that undue influence principles are not restricted to marriages.

They may apply in circumstances involving:

employer and employee;

business relationships;

financial dependence;

professional relationships.

The lender may be put on inquiry where the circumstances indicate a substantial risk of undue influence.

22. Royal Bank of Scotland plc v Etridge (No 2)

Royal Bank of Scotland plc v Etridge (No 2)

[2001] UKHL 44; [2002] 2 AC 773

This is the leading modern authority.

The House of Lords considered a group of cases involving guarantees and charges over homes.

Major principles

The court explained that:

Undue influence is a single equitable doctrine.

Actual and presumed influence represent different methods of proof.

A relationship of influence may be established by the circumstances.

Recognised relationships are not an exhaustive list.

The transaction must be examined in context.

A transaction not readily explicable by ordinary motives may raise a presumption.

Independent legal advice is an important means of rebutting the presumption.

Lenders may be put on inquiry.

Proper procedures can protect lenders from later challenges.

The judgment specifically states that relationships of influence cannot be confined to an exhaustive list because relationships are infinitely varied.

23. Inche Noriah v Shaik Allie Bin Omar

Inche Noriah v Shaik Allie Bin Omar

[1929] AC 127

This Privy Council decision is an important authority concerning substantial gifts and independent advice.

It illustrates that:

a person may have formally understood a transaction;

but the circumstances surrounding the transaction can still be examined;

independent and competent advice is highly relevant;

a person benefiting from the transaction may need to demonstrate that it was freely made.

The case is frequently associated with the importance of independent advice in rebutting presumed undue influence.

24. Lloyds Bank Ltd v Bundy

Lloyds Bank Ltd v Bundy

[1975] QB 326

Lord Denning MR discussed relationships involving inequality, pressure and abuse of influence.

The case involved a farmer who provided security for his son's debts in circumstances involving a very close relationship with his bank.

Although the broader doctrine of inequality of bargaining power discussed in the judgment should not be treated as identical to modern undue influence doctrine, the case remains historically important for understanding equitable protection against exploitation of vulnerable parties.

25. Modern Understanding of the Doctrine

The modern approach can be represented as:

Relationship of influence

↓

Improper influence or evidential circumstances

↓

Transaction

↓

Loss of free and independent judgment

↓

Equitable intervention

This is preferable to treating undue influence as merely a mechanical list of categories.

Recent authorities continue to describe undue influence as a unitary doctrine.

26. Transaction “Not Readily Explicable by Ordinary Motives”

This is an important modern test.

Suppose a parent gives a child a modest birthday gift.

That is readily explicable by ordinary motives.

But suppose:

the parent transfers almost all assets;

the recipient is a caregiver;

the parent relies completely upon the caregiver;

no independent advice was obtained.

That transaction may require an explanation.

The court does not simply ask:

“Was it disadvantageous?”

It examines the transaction in the context of the relationship.

This approach derives from Allcard and was reaffirmed in Etridge.

27. Independent Legal Advice

Independent legal advice is one of the most important safeguards.

A person challenging a transaction may argue:

“I did not make an independent decision.”

The defendant may respond:

“The claimant received competent independent legal advice and chose freely.”

Proper advice should ordinarily explain:

the nature of the transaction;

legal consequences;

financial risks;

alternatives;

potential disadvantages.

However:

Independent advice is important evidence, not an automatic immunity.

The circumstances surrounding the advice must still be examined.

28. Third-Party Transactions

A particularly important situation is:

A influences B → B enters transaction with C.

For example:

Husband → influences wife → wife guarantees husband's debt → bank seeks enforcement.

The bank's rights depend partly upon whether the bank:

knew of the circumstances;

was put on inquiry;

followed appropriate protective procedures.

The O'Brien and Etridge cases established the principal framework.

29. Modern Position on Lenders

The modern approach was recently considered again in:

Waller-Edwards v One Savings Bank plc

The UK Supreme Court confirmed the continuing importance of the O'Brien/Pitt/Etridge line of authority.

In appropriate three-party non-commercial surety transactions, lenders are put on inquiry about the possibility that the vulnerable party's consent was obtained through undue influence.

The Supreme Court explained that the lender may then need to follow the Etridge protocol, including ensuring that the vulnerable party receives appropriate independent legal advice.

This is significant because it confirms that the doctrine remains relevant to modern mortgage and refinancing transactions.

30. Persons and Transactions Protected

Undue influence may become relevant in:

Property transactions

property transfers;

mortgages;

charges;

gifts.

Financial transactions

guarantees;

loans;

investments;

settlements.

Estate planning

gifts;

lifetime transfers;

certain testamentary disputes, subject to the separate law governing wills.

Fiduciary transactions

trustee-beneficiary transactions;

solicitor-client transactions;

adviser-client transactions.

Family transactions

guarantees;

transfers between relatives;

business security.

31. Undue Influence and Wills

Undue influence can also arise in disputes concerning testamentary dispositions, but the legal test for challenging a will requires care.

A traditional distinction is made between:

persuasion and coercion.

A person can persuade a testator to make a particular gift without the will being invalid.

For a testamentary undue influence claim, the issue is whether the testator's free will was overborne.

The classic expression is that a testator may be “led but not driven.”

The authorities include:

Wingrove v Wingrove (1885) 11 PD 81;

In re T [1992] EWCA Civ 18.

Thus, merely proving that someone influenced a testator is not necessarily enough.

32. Undue Influence and Capacity

Undue influence and lack of capacity are different concepts.

Lack of capacity

Focuses on whether the person had the legal/mental capacity to make the relevant decision.

Undue influence

Focuses on whether the person, despite having capacity, exercised genuinely independent judgment.

Therefore:

A person may have full legal capacity and nevertheless be a victim of undue influence.

Conversely, lack of capacity does not automatically establish undue influence.

33. Undue Influence and Duress

These doctrines overlap but are not identical.

Modern authority increasingly treats illegitimate threats as matters for duress, rather than attempting to force them into undue influence doctrine.

34. Undue Influence and Unconscionable Bargain

These doctrines are related but separate.

Undue influence

Question:

Was the transaction produced by improper influence?

Unconscionable bargain

Question:

Was a seriously disadvantaged person exploited so that an unconscionable transaction resulted?

A factual situation may potentially engage both doctrines.

The Supreme Court has recognised undue influence and unconscionable bargain as distinct equitable doctrines addressing different forms of exploitation.

35. Evidence in Undue Influence Cases

Important evidence may include:

Documentary evidence

deeds;

contracts;

bank statements;

loan documents;

guarantees;

wills;

emails;

text messages;

financial records.

Witness evidence

claimant;

family members;

solicitor;

bank employee;

financial adviser;

caregiver;

doctor, where relevant.

Circumstantial evidence

sudden change in financial arrangements;

isolation;

dependency;

unusual gift;

absence of independent advice;

substantial benefit to the influencer;

unexplained property transfer.

36. Questions the Court May Consider

The court may ask:

Who exercised influence?

What was the source of that influence?

Did the claimant trust the defendant?

Was the claimant dependent upon the defendant?

Was the influence improperly exercised?

Did the influence cause the transaction?

Was the transaction unusual?

Was it beneficial to the person exercising influence?

Did the claimant obtain independent advice?

Was the advice competent and genuinely independent?

Did a third party know of the circumstances?

Was the transaction subsequently affirmed?

Has there been excessive delay?

Can the parties be restored to their previous positions?

37. Remedies

The principal equitable remedy is generally setting aside the transaction.

Possible relief may include:

1. Rescission

The transaction may be avoided.

2. Restitution

Property or money may be returned where appropriate.

3. Declaration

The court may declare that a transaction or security is not enforceable.

4. Injunction

The court may restrain enforcement or further dealing with the property.

5. Equitable proprietary relief

Where property has been transferred and tracing principles apply, proprietary remedies may potentially become relevant.

The precise remedy depends upon:

the transaction;

third-party rights;

delay;

affirmation;

restitution;

intervening circumstances.

38. Bars to Relief

Equitable relief can be affected by:

Delay

A claimant who waits too long may face difficulty.

Affirmation

If the claimant, after becoming aware of the circumstances, freely confirms the transaction, relief may be affected.

Acquiescence

Conduct indicating acceptance can be relevant.

Third-party rights

An innocent third party may acquire rights that complicate rescission.

Restitution

The court may consider whether the parties can substantially be restored to their previous positions.

Allcard v Skinner is particularly important for the effect of delay and equitable considerations.

39. Claimant's Litigation Strategy

A claimant should generally establish the following sequence:

Step 1 — Identify the relationship

Show trust, confidence, dependence or influence.

Step 2 — Identify vulnerability

Explain why the claimant was susceptible to influence.

Step 3 — Identify the transaction

Specify exactly what was signed, transferred or guaranteed.

Step 4 — Identify the benefit

Show who benefited.

Step 5 — Establish influence

Demonstrate actual influence or circumstances supporting a presumption.

Step 6 — Establish causation

Connect the influence with the transaction.

Step 7 — Examine independent advice

Determine whether genuinely independent advice was obtained.

Step 8 — Examine third parties

Identify banks, purchasers, advisers or other institutions.

Step 9 — Address equitable bars

Consider delay, affirmation and acquiescence.

Step 10 — Seek appropriate relief

Ask for rescission, declaration, injunction or restitution as appropriate.

40. Defence to an Undue Influence Claim

A defendant may argue:

No relationship of influence existed.

The claimant acted independently.

No improper influence was exercised.

The transaction was ordinary.

The transaction was consistent with the parties' relationship.

The claimant received independent legal advice.

The claimant understood the transaction.

The alleged influence did not cause the transaction.

The claimant subsequently affirmed the transaction.

The claimant delayed excessively.

Third-party rights have intervened.

Restitution is impossible or inequitable.

41. Case Law Table

42. Six Cases to Memorize

For examination purposes, remember:

1. Allcard v Skinner

Confidential relationship + substantial gift

2. O'Brien

Undue influence + third-party lender

3. Pitt

Actual undue influence + no separate manifest-disadvantage requirement

4. Burch

Non-family relationship + lender put on inquiry

explanation for transaction;

independent advice;

Allcard v Skinner.

45. Difference Between Influence and Undue Influence

46. Important Modern Principle

The modern law should not be reduced to a mechanical formula such as:

“Relationship + bad bargain = undue influence.”

That is incorrect.

The court considers the whole factual context.

Recent authority reiterates that undue influence is a unitary doctrine and that “actual” and “presumed” influence concern different methods of proving the doctrine rather than two fundamentally different wrongs.

47. Exam-Style Conclusion

Undue influence on persons is an important equitable doctrine designed to protect free and independent decision-making. It becomes relevant where one person possesses influence over another and improperly uses that influence to obtain a transaction or advantage.

The modern law recognises two principal evidential routes: actual undue influence, established through direct evidence of improper influence, and presumed undue influence, established through a relationship of influence combined with a transaction that is not readily explicable by ordinary motives.

The leading authorities include Huguenin v Baseley, Allcard v Skinner, National Westminster Bank v Morgan, Barclays Bank v O'Brien, CIBC Mortgages v Pitt, Credit Lyonnais v Burch, Inche Noriah v Shaik Allie Bin Omar, and Royal Bank of Scotland v Etridge (No 2).

The central principle can be remembered as:

Equity protects a person where another has improperly used influence so that the person's apparent consent does not represent a genuinely free and independent judgment.

One-line revision formula:

Undue Influence = Relationship of Influence + Improper Abuse + Causation + Equitable Remedy
