Contesting a Will
When a family member passes away and their will contains unexpected terms, you may wonder if your loved one was coerced or pressured into making decisions that didn't reflect their true wishes. Understanding undue influence in will-making can help you determine if you have grounds to contest a will in New South Wales.

Understanding Undue Influence in Will Making
What constitutes undue influence? Undue influence occurs when someone coerces a will-maker (testator) into creating a will that goes against their genuine intentions. This goes beyond simple persuasion or advice – it involves overriding the person's free will through manipulation or pressure.
For a will to be legally valid in NSW, it must be made freely and voluntarily. If the court determines that undue influence affected the will's creation, the document can be declared invalid.
Key Elements Required to Prove Undue Influence
To successfully challenge a will on grounds of undue influence, you must demonstrate four critical elements:
1. Suspicious Will Provisions
The will must dispose of assets in unexpected ways that raise red flags, such as:
Immediate family members being completely excluded without explanation
Disproportionate gifts to one person over others
Sudden changes that contradict the deceased's previously expressed wishes
2. Dependency Relationship
Evidence must show the deceased was reliant on or trusted the alleged influencer, including:
Financial dependence
Emotional reliance
Physical care arrangements
Professional relationships (carer, advisor, etc.)
3. Vulnerability to Influence
The will-maker must have been susceptible to coercion due to factors such as:
Advanced age or frailty
Mental health conditions
Social isolation
Physical illness or disability
4. Benefit to the Influencer
The person alleged to have exerted undue influence must have benefited from the new will provisions.
The Challenge of Proving Undue Influence
Why is undue influence difficult to prove? The legal standard for proving undue influence is deliberately high. Courts require clear evidence that the will-maker's decision-making was completely overridden, not merely influenced by persuasion or emotional appeals.
Since the deceased cannot explain their reasoning, courts rely heavily on witness testimony from:
Medical professionals who treated the deceased
Family members and close friends
Legal advisors involved in will preparation
Care providers or household staff
Common Scenarios Where Undue Influence May Occur
Elder Abuse Situations
Elderly individuals may be particularly vulnerable to undue influence, especially when:
They depend on one family member for daily care
They have limited social contact with others
They experience cognitive decline or memory issues
Blended Family Dynamics
Undue influence concerns often arise in blended families where:
New spouses influence decisions about inheritance
Step-children are unexpectedly favoured or excluded
Long-standing family relationships are suddenly altered
Professional Relationships
Sometimes undue influence involves professional carers, advisors, or service providers who:
Gain the deceased's trust over time
Isolate them from family members
Benefit unexpectedly from will changes
Building Your Case: Evidence You'll Need
Documentation
Previous wills showing different intentions
Medical records indicating vulnerability periods
Financial records showing dependency relationships
Communication records (emails, letters, messages)
Witness Testimony
Statements from family members about relationship changes
Medical professional observations about mental capacity
Evidence of isolation from other family members
Records of unusual financial transactions
When to Combine Claims
Undue influence and lack of capacity claims often work together. If someone lacks the mental capacity to make decisions, they're more vulnerable to influence. Consider pursuing both claims simultaneously when:
Medical evidence suggests cognitive impairment
The timing of will changes coincides with health decline
Multiple concerning factors are present
Alternative Legal Options
If proving undue influence seems challenging, other options for contesting a will may include:
Family Provision Claims
If you're an eligible person who hasn't received adequate provision from the estate, you may have grounds for a family provision claim under NSW succession law.
Lack of Testamentary Capacity
Challenging the will-maker's mental capacity at the time of signing may be easier to prove than undue influence.
Fraud or Forgery Claims
If you suspect the will document itself is fraudulent or signatures were forged.
Steps to Take If You Suspect Undue Influence
1. Gather Evidence Quickly
Time is critical in will disputes. Begin collecting:
Relevant documents and communications
Contact information for potential witnesses
Medical records and professional assessments
2. Seek Expert Legal Advice
Will contest cases involving undue influence are complex and require specialised knowledge of NSW succession law. An experienced will dispute lawyer can:
Assess the strength of your case
Guide evidence collection
Explain your legal options
Represent you in court proceedings
3. Consider Mediation
Many will disputes can be resolved through mediation, which is often faster and less expensive than court proceedings.
Time Limits for Will Contests
In NSW, you generally have 12 months from the grant of probate to contest a will. However, courts may extend this timeframe in exceptional circumstances. Acting quickly protects your legal rights and preserves evidence.
Getting Professional Help
Challenging a will on grounds of undue influence requires careful legal strategy and thorough evidence preparation. The high legal standard for proving coercion means that expert guidance is essential for success.
If you believe your loved one was coerced into making a will that doesn't reflect their true intentions, contact an experienced NSW will dispute lawyer to discuss your options.
