Background

Kevin John Kohnen died in September 2022 while domiciled in Illinois. His surviving spouse, Deborah Kohnen, initially petitioned for letters of administration on the theory that Kevin died intestate. Kevin’s children from a prior relationship, Ethan Kohnen and Jordan Aken, challenged that representation, producing a will — which left nothing to Deborah — and obtained supervised administration. Deborah contested the will’s validity and, in December 2023, formally renounced it. Under section 2-8(a) of the Illinois Probate Act of 1975, a surviving spouse who renounces a will is entitled to one-third of the testator’s “entire estate” when a descendant survives.

The dispute centered on proceeds from the sale of Arizona real property that Kevin had acquired before the marriage. Ethan and Jordan moved for a declaration that those proceeds were excluded from the “entire estate” for purposes of calculating Deborah’s renunciation share. The McHenry County circuit court denied the motion, reasoning that it had authority to administer the Arizona property in Illinois. No appellee’s brief was filed in the appellate court.

Because no appellee’s brief was filed, the appellate court applied the standard from First Capitol Mortgage Corp. v. Talandis Construction Corp., 63 Ill. 2d 128 (1976): if the appellant’s brief demonstrates a prima facie case of reversible error supported by the record, the judgment may be reversed without the court serving as advocate for the appellee.

The Court’s Holding

The Illinois Appellate Court, Second District, reversed and remanded. Relying on In re Estate of Pericles, 266 Ill. App. 3d 1096 (1994), the court held that out-of-state real property is governed by the law of the situs, not Illinois law, and therefore falls outside the “entire estate” used to calculate a surviving spouse’s renunciation share under section 2-8(a). Because Illinois conflict-of-laws principles — tracking the Restatement (Second) of Conflict of Laws — require situs law to control the administration of immovable property, Kevin’s Arizona real property was not part of his Illinois “entire estate.”

The court further found that Arizona law provided no forced share for a surviving spouse, and Deborah had not argued that any other state’s law (rather than Arizona’s) would have applied in an Arizona situs court. Her reliance on an Arizona statute governing homestead and family allowances for non-domiciliary decedents was unpersuasive, as the court found no clear basis for treating those provisions as encompassing a renunciation right. Similarly, Arizona’s simplified ancillary-administration procedure — which allows a foreign personal representative to act without opening full ancillary probate — had no bearing on the choice-of-law question.

The appellate court emphasized that Pericles constitutes binding precedent on Illinois circuit courts regardless of locale, and the trial court was not free to depart from it. Ethan and Jordan having established a prima facie case for reversal, the court reversed and remanded for further proceedings consistent with the opinion.

Key Takeaways

  • Under Illinois conflict-of-laws principles, the law of the situs governs interests in out-of-state real property; such property is excluded from the “entire estate” used to compute a surviving spouse’s one-third renunciation share under 755 ILCS 5/2-8(a).
  • In re Estate of Pericles remains controlling authority in Illinois: a decedent’s out-of-state realty is administered under situs law and does not factor into the Illinois statutory spousal share calculation.
  • Where Arizona law provides no forced share for a surviving spouse, a surviving spouse renouncing an Illinois will has no claim to Arizona real property through the Illinois renunciation mechanism.
  • An appellee’s failure to file a brief does not require reversal automatically, but if the appellant makes a prima facie showing of reversible error supported by the record, reversal is appropriate under Talandis.

Why It Matters

This decision reinforces a significant limitation on the Illinois spousal renunciation right: the statutory one-third share applies only to assets properly within the Illinois estate. Attorneys advising surviving spouses — or estate planners structuring multi-state holdings — must account for the fact that out-of-state real property will be governed by situs law, which may afford the surviving spouse little or no forced share. In community-property states or states with no forced-share statute, the renouncing spouse could receive nothing from those assets despite a robust Illinois marital interest argument.

The case also serves as a reminder of the procedural stakes in probate appeals: the failure to file an appellee’s brief exposed Deborah to reversal under the Talandis prima facie standard. For practitioners representing estate beneficiaries or administrators in Illinois appellate proceedings, participation is essential — silence can be outcome-determinative even when the underlying legal question is genuinely contested.
