Updated September 7, 2026. Quick answer: In Illinois, illinois requires bond by default for every individual representative (executor or administrator) before undertaking their duties (755 ILCS 5/12-2(a)); Illinois’s code has no UPC-style informal/formal distinction, and choosing independent (unsupervised) administration under Article XXVIII does not itself remove the bond requirement.
Does Illinois require an executor to post a bond?
Illinois requires bond by default for every individual representative (executor or administrator) before undertaking their duties (755 ILCS 5/12-2(a)); Illinois’s code has no UPC-style informal/formal distinction, and choosing independent (unsupervised) administration under Article XXVIII does not itself remove the bond requirement.
“before undertaking the representative’s duties, every individual representative shall take and file an oath or affirmation…and shall file in and have approved by the court a bond binding the individual representative so to do.”

Can the will waive it in Illinois?
Yes. 755 ILCS 5/12-4(a) excuses security for a person ‘excused by the will from giving bond or security’ (and caps security at whatever amount the will specifies), unless the court has cause to suspect fraud/incompetence or believes the estate is insufficient to cover claims.
If a DIY will is the right route for you in Illinois
Because Illinois’s own bond rule turns on what your will says, a properly executed will is the actual lever here, not paperwork on the side. LawDepot builds a state-specific last will and testament, which you then sign and witness under your state’s rules.

Can the heirs or beneficiaries waive it in Illinois?
No. The waiver mechanism found in the sections fetched (5/12-2, 5/12-4) runs through the will’s terms, not through heir or beneficiary consent; no heir-waiver provision was located in this article.
If a bond is required, how much?
When a bond is required, Illinois sizes it at 200% of the estimated value of the personal estate, per its own bond-amount statute.
“not less than double the value of the personal estate if individuals act as sureties or if bond or security is excused, and not less than 1 1/2 times the value of the personal estate if a surety company acts as surety”

What makes Illinois different
Illinois keeps the bond/no-bond decision purely a function of the will’s language regardless of whether the estate proceeds under supervised or independent administration, unlike UPC states where the informal/unsupervised track itself defaults to no bond.
