A will contest is one of the most painful disputes a family can face β€” a formal challenge to whether a will is valid, brought by someone who believes it does not reflect the true wishes of the person who died. These cases turn on hard questions: Was the will-maker of sound mind? Were they pressured or manipulated? Was the document properly signed and witnessed, or even genuine? We represent both sides of these disputes in DuPage County β€” heirs who have real grounds to challenge a will, and executors and beneficiaries defending a valid one against an opportunistic attack.

We handle will contests for families across DuPage County and the western suburbs, whether you are raising a challenge or defending against one. You work directly with the attorney on your case, we tell you honestly whether the grounds are strong or weak before you invest in a fight, and we pursue resolution β€” through negotiation where possible and litigation where necessary. These disputes are emotional and time-sensitive, and how they are handled early shapes everything that follows.

Grounds for Contest

When Illinois Wills Can Be Challenged

Illinois recognizes specific grounds. General disagreement with the will’s distribution is not enough.

Lack of Capacity

Decedent lacked testamentary capacity at signing, typically due to dementia, severe illness, or cognitive impairment.

Undue Influence

Someone in a position of trust or confidence exerted improper pressure on the decedent to change the will in their favor.

Fraud

Decedent was deceived about the will’s contents or about facts that influenced their decisions (e.g., false statements about other beneficiaries).

Duress

Decedent was threatened or coerced into signing the will against their true wishes.

Improper Execution

Will doesn’t meet Illinois execution requirements, wrong number of witnesses, witnesses who were beneficiaries, missing notary, etc.

Forgery

Signature or content was forged. Less common but does occur, particularly with last-minute amendments or codicils.

The Process

Will Contest Timeline

01

6-Month Deadline

Illinois law gives interested parties 6 months from the will’s admission to probate to file a contest. Missing this deadline is fatal.

02

Petition Filing

We file the will contest petition specifying grounds. Discovery commences shortly after.

03

Discovery

Medical records, witness depositions, document review. Often the most expensive phase of a contest.

04

Resolution

Most contests resolve through negotiated settlement. Some proceed to trial. We prepare every case for trial regardless of settlement prospects.

Reality Check

Honest Assessment Matters Here

Standing required

You must be an ‘interested person’ (typically a beneficiary under a prior will, or an intestate heir) to contest. Friends and distant relatives often lack standing.

Strict 6-month deadline

Missing the contest deadline ends the matter. Don’t wait, even informal investigation should start immediately.

Burden of proof

Contestants bear the burden of proving grounds. Mere suspicion is not enough. Documentary and witness evidence is critical.

No-contest clauses

Some wills include in terrorem clauses that disinherit anyone who contests. Illinois courts enforce these in limited circumstances. We assess case-by-case.

Cost-benefit reality

Will contests are expensive ($30K-150K+ typical). Realistic chances of recovery should justify the cost. We tell you the honest math.

Settlement is common

Most contests settle. Even weak cases often produce some settlement value because defendants want to end the dispute and unfreeze the estate.

Grounds for a Contest

You Can’t Contest a Will Just Because It Feels Unfair

Being unhappy with what a will leaves you is not, by itself, a reason a court will set it aside. Illinois recognizes specific legal grounds for a will contest, and a challenge has to fit one of them. The most common are lack of testamentary capacity β€” the person did not understand what they owned or who their natural heirs were when they signed; undue influence β€” someone in a position of trust pressured or manipulated them into changing the will; improper execution β€” the will was not signed and witnessed as Illinois law requires; and fraud or forgery. We assess which, if any, of these apply before a case is ever filed.

There are also strict limits on who can contest and how long they have to do it. Generally, only a person who would inherit more if the will were invalid β€” an interested person β€” has standing, and Illinois imposes a short window, typically six months from the will’s admission to probate, to file. Miss it and the right is usually gone for good. If you suspect a will does not reflect your loved one’s true wishes, or you are defending one that does, the time to act is now, not later.

Will Contest FAQ

Common Questions

Six months from the date the will is admitted to probate. This deadline is strict, missing it almost always ends your ability to contest. If you suspect grounds for contest, consult counsel immediately, even before the deadline appears imminent.

No. Illinois requires specific grounds: lack of capacity, undue influence, fraud, duress, or improper execution. Simply feeling the distribution is unfair is not legal grounds. Many family members consult us about contesting and ultimately conclude the will, while emotionally painful, is legally valid.

An ‘interested person’, typically someone who would inherit under a prior will, under intestacy if there were no will, or under specific statutory provisions. Friends, neighbors, and disinherited extended family typically lack standing to contest.

Improper pressure exerted on the decedent by someone in a position of trust or confidence that overcame their free will and resulted in a will favoring the influencer. Common in cases involving elderly decedents and caregivers, late-life marriages, isolated decedents, and substantial recent changes to estate plans.

Will contests are nearly always hourly billed due to unpredictable scope. Typical contests run $30K-150K. Complex contests with extensive discovery or trial can run higher. Some attorneys take contests on contingency for clear cases with substantial recovery potential.

Hard to give a number, depends entirely on the strength of evidence. Cases with clear documentary evidence (medical records showing severe dementia at signing, financial records showing isolation by influencer, evidence of fraud) succeed more often. Cases based on suspicion alone usually don’t.

Illinois allows a will to be challenged on specific grounds: lack of testamentary capacity (the person did not understand their assets or heirs), undue influence (they were pressured or manipulated), improper execution (the will was not signed and witnessed correctly), and fraud or forgery. Disagreeing with how the estate was divided is not enough on its own. We evaluate the facts against these grounds and tell you candidly whether you have a case worth pursuing.

In Illinois the window is short β€” generally six months from the date the will is admitted to probate. After that, the right to contest is usually lost, no matter how strong the underlying claim. Because evidence and witnesses also fade quickly, will contests are time-sensitive in every sense. If you are considering a challenge or expect one, it is important to speak with an attorney right away so the deadline does not pass while you decide.
