Will contests are some of the most emotionally charged probate proceedings. Family members challenging a will believe a loved one’s true wishes weren’t honored โ€” that an elderly parent was manipulated, that a caregiver exerted improper influence, that the will doesn’t reflect who the decedent really was. The grounds for contest are narrow under Illinois law, but the cases are real and they require real preparation.

We’ve represented both sides โ€” petitioners challenging will validity and beneficiaries defending wills against contest โ€” in DuPage and Cook County probate courts for over three decades. Honest case assessment is critical: not every difficult family situation justifies a will contest, and not every contest is winnable. We tell you straight at the consultation.

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 โ€” 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 โ€” wrong number of witnesses, witnesses who were beneficiaries, missing notary, etc.

Forgery

Signature or content was forged. Less common but does occur โ€” 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 โ€” 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.

Will Contest FAQ

Common Questions

Six months from the date the will is admitted to probate. This deadline is strict โ€” 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’ โ€” 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 โ€” 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.
