Wills can pass through probate without challenge, but when disputes arise, understanding your legal options becomes critical. In Illinois, a will can be contested on specific legal grounds, but the process requires meeting strict procedural requirements and proving your case with clear evidence. Whether you believe a will was created under undue influence, the testator lacked capacity, fraud occurred, or the will wasn’t properly executed, knowing what you must prove—and who has the right to challenge it—can make the difference in protecting your interests.
This comprehensive guide explains the four main grounds for contesting a will in Illinois, the six-month deadline you must meet, and what evidence courts require to invalidate a will. At Peck Ritchey, LLC, our experienced probate litigation attorneys understand the complexities of will contests and can guide you through every step of the process.
Who Can Contest a Will in Illinois?
Not everyone can challenge a will. Illinois law limits who has standing to contest a will to “interested persons“—those with a direct financial stake in the outcome. This includes heirs, legatees named in the will, creditors of the estate, and the estate’s personal representative.
The key requirement is demonstrating a direct pecuniary interest that would be affected by the will’s validity. Simply being disappointed by the distribution or believing the will is unfair is not enough. You must show that you would benefit financially if the will were invalidated. Standing is the first hurdle you must clear before any court will even consider the grounds for your challenge. Understanding who qualifies as an interested person is essential to determining whether you have the legal right to pursue a will contest. If you’re uncertain about your standing, our probate litigation team can evaluate your situation and advise you on your options.
The 6-Month Deadline: Why Timing Matters
Illinois Probate Act Section 8-1 establishes a strict 6-month window to contest a will after it has been admitted to probate. This deadline is not flexible. If you miss it, you lose your right to challenge the will in court, regardless of how strong your evidence might be. The clock starts ticking the moment the will is admitted to probate, not when you discover potential problems.
This is why acting quickly and consulting with an attorney as soon as you suspect grounds for a contest is essential. Waiting to gather evidence or hoping the issue resolves itself can cost you your legal rights. Understanding the probate process and timeline is critical to protecting your interests in will contest cases. The probate timeline moves quickly, and missing the deadline can permanently bar your claim. Contact (312) 201-0900 immediately if you believe you have grounds to contest a will.

Undue Influence: When Someone Improperly Pressures the Testator
Undue influence occurs when someone exerts improper pressure on the testator, causing them to make decisions they would not have made of their own free will. To prove undue influence, you must establish four elements: (1) the testator was susceptible to influence due to age, illness, or mental weakness; (2) the influencer had an opportunity to exert influence; (3) the influencer had a motive or benefit from the will’s terms; and (4) the will’s provisions are the result of that influence.
Courts pay special attention when a fiduciary relationship exists—such as between a caregiver and elderly person, or an advisor and client. In these cases, the burden shifts: if you show the fiduciary benefited from the will, they must prove the influence was legitimate.
Common scenarios include a caregiver who becomes the primary beneficiary, a family member who isolates the testator from others, or an advisor who stands to gain significantly from the terms of the will. Undue influence claims often involve complex factual disputes and require substantial evidence to succeed. For more detailed information on this topic, see our comprehensive guide on understanding undue influence in estate disputes. If you suspect undue influence affected a will, gathering evidence early is critical to building a strong case. Medical records, witness testimony, and documentation of the testator’s isolation or vulnerability can all support an undue influence claim.
Lack of Testamentary Capacity: Proving the Testator Wasn’t Mentally Fit
Testamentary capacity is the legal and mental ability to make a valid will. The testator must understand the nature and extent of their estate, know the family members who would naturally inherit, and understand the disposition being made by the will. Illinois law presumes the testator was mentally sound, meaning you bear the burden of proving they lacked capacity at the time they signed the will. This is a high bar. Conditions like dementia, Alzheimer’s disease, severe mental illness, or the effects of medication can impair capacity, but you must present clear evidence.
Medical records, testimony from doctors who treated the testator, witness statements from people who observed the testator’s mental state, and expert evaluations all help build your case. The key is showing the testator’s condition affected their understanding at the specific moment they executed the will. Lack of mental capacity claims require careful documentation and often benefit from expert medical testimony. Courts examine the testator’s mental state at the precise time the will was signed, not their condition before or after that moment. If the testator was diagnosed with a cognitive disorder before signing the will, this can strengthen your capacity challenge.

Fraud and Forgery: When Deception or Falsification Occurs
Fraud and forgery are distinct grounds for contesting a will, though both involve dishonesty.
- Fraud occurs when someone makes a false statement or misrepresentation that deceives the testator into signing a will they would not have signed otherwise. For example, telling the testator that a beneficiary is in financial distress when they are not, or hiding the true contents of the will.
- Forgery involves falsifying the testator’s signature, forging witness signatures, or tampering with the document itself.
Both require clear and convincing evidence—a higher standard than typical civil cases. You must prove the deception or falsification actually caused the testator to act differently. Circumstantial evidence, handwriting analysis, witness testimony, and document examination all play roles in building these claims. Fraud and forgery cases often require expert witnesses to establish the falsification or deception. These grounds can be particularly effective when documentary evidence clearly shows tampering or forgery. If you suspect the will document itself has been altered or forged, document preservation and expert analysis are essential. Our probate litigation attorneys have extensive experience with fraud and forgery cases.
Improper Execution: When the Will Doesn’t Meet Legal Requirements
Illinois law requires wills to meet specific formal execution requirements. The testator must sign the will, and the signature must be witnessed by at least two competent witnesses who also sign the document. The witnesses must sign in the testator’s presence, and the testator must be present when each witness signs. The will must be dated. Failure to meet these requirements can invalidate the entire will.
Common execution errors include witnesses who are beneficiaries under the will (which voids that beneficiary’s gift under 755 ILCS 5/4-6 unless at least two other disinterested witnesses sign), signatures in the wrong location, missing dates, or witnesses who did not observe the testator sign.
Illinois applies strict compliance as the mandatory standard for will execution. Courts do not recognize a substantial compliance doctrine and do not excuse minor deviations from statutory formalities. If you can show the will was not properly executed, you have strong grounds for invalidation. Improper execution claims are often the most straightforward to prove because they involve objective legal requirements rather than subjective factual disputes. Reviewing the will’s execution procedures carefully can reveal technical defects that invalidate the entire document. For guidance on will execution requirements, consult with our estate planning attorneys.
Frequently Asked Questions About Will Contests in Illinois
How much does it cost to contest a will in Illinois?
The cost varies significantly based on the complexity of your case, the grounds you’re pursuing, and whether the case settles or goes to trial. Expenses include attorney fees, court filing fees, costs for expert witnesses (medical doctors, handwriting analysts, accountants), and discovery costs. Some cases settle relatively quickly, reducing overall expense. Others require extensive litigation. During your initial consultation, an attorney can provide a more specific estimate based on your particular situation. Understanding the potential costs upfront helps you make an informed decision about pursuing your claim. Many will contest that cases can be resolved through negotiation and settlement, which reduces overall litigation expenses. Our About Us page provides information about our firm’s experience and approach to client representation.
Can I contest a will if I’m not mentioned in it?
Not automatically. You must have standing as an “interested person” with a direct financial interest. Being omitted from a will does not automatically grant you standing unless you would have inherited under Illinois’ intestacy law if there were no will. However, the doctrine of equitable adoption may apply in limited circumstances, allowing non-statutory heirs to gain standing through clear and convincing evidence that they were adopted in fact, even if not legally. Determining whether you have standing requires careful analysis of Illinois probate law and your relationship to the deceased. If you believe you should have inherited but were omitted, consult with an attorney to evaluate your legal options. Our probate litigation team can assess your specific situation.
What happens if I lose a will contest?
If your challenge is unsuccessful, the will stands as written and the distribution proceeds according to its terms. In some cases, the court may award attorney fees to the prevailing party, meaning you could be responsible for the other side’s legal costs. If the will contains a no-contest clause, an unsuccessful challenge might trigger penalties against your inheritance. This underscores the importance of having strong legal representation and a solid factual basis before filing. Consulting with an experienced estate litigation attorney before pursuing a will contest can help you assess the strength of your claim. A thorough evaluation of your case can help you understand the risks and potential outcomes before proceeding.
Do I need an attorney to contest a will?
Yes, strongly. Will contests involve complex legal standards, burdens of proof, and procedural requirements. Mistakes in how you present evidence, file documents, or meet deadlines can be costly and may result in dismissal of your case. An experienced estate litigation attorney ensures your rights are protected and your case is presented effectively. Peck Ritchey, LLC has the expertise to guide you through this process. Attempting to contest a will without legal representation significantly increases the risk of losing your claim due to procedural errors or insufficient evidence. Our attorneys can help you handle the probate court system and present your case persuasively.
What is the difference between contesting a will and contesting a trust?
Wills and trusts operate under different legal frameworks and have different contest procedures. Wills go through probate court and are subject to the Illinois Probate Act. Trusts are typically private documents, and contests may be handled differently, sometimes outside of court. The grounds for challenging each—undue influence, lack of capacity, fraud—are similar, but the procedures and timelines differ. If you’re facing a dispute involving either a will or a trust, consult with an attorney who handles both to understand your specific options. Trust contests often involve different procedural requirements and may offer different remedies than will contests. Understanding which type of document you’re challenging is essential to pursuing the correct legal strategy.
