In re Marriage of Field

Overview

In re Marriage of Field , 2026 IL App (5th) 240405-U, involves consolidated appeals from multiple postdissolution orders addressing attorney fees, sanctions, and child support true-up calculations under a marital settlement agreement. The Fifth District affirmed the trial court's awards of attorney fees and sanctions and its authority to consider true-up years 2016–2022, but reversed on three issues: the failure to credit the father for dependent child-in-care social security benefits, the imputation of income under an enforcement (not modification) motion, and the premature application of statutory interest.

Key Facts

Parties divorced in 2013 with a marital settlement agreement (MSA) requiring Dennis to pay $1,300/month base child support plus additional support so total annual support equaled 28% of his statutory net income, with tax returns due to Della by March 31 each year.

Della filed a motion in 2017 for a child support true-up for 2016; the trial court ultimately addressed true-ups for 2016–2022.

The trial court imputed Dennis's 2016 income to years 2017–2022, finding he was not forthcoming about his finances.

Della received social security dependent child-in-care benefits derived from Dennis's earnings record; the trial court credited Dennis only for the children's direct dependent allotment, not the child-in-care benefit paid to Della.

The trial court imposed statutory interest on additional child support from March 31 of each year, treating that as the due date despite the MSA only requiring tax return disclosure by that date.

Dennis filed an inaccurate financial affidavit; a prior motion for sanctions had been denied in March 2022, but the trial court granted the same motion in December 2023 without Dennis raising res judicata.

Procedural History

Circuit Court of Bond County (No. 13-D-1), Judge Maureen D. Schuette presiding. Dennis, proceeding pro se on appeal, filed three separate notices of appeal from orders entered December 4, 2023, February 22, 2024, March 4, 2024, and April 4, 2024. Cases 5-24-0405 and 5-24-0593 were consolidated; case 5-24-0467 was severed and separately disposed of. A prior appeal was resolved in In re Marriage of Field , 2019 IL App (5th) 160405-U.

Holdings

Attorney fees (affirmed): No abuse of discretion in proceeding on the July 2019 petition rather than the February 2021 amended petition; the petitions were substantively identical and Dennis suffered no prejudice, as the court evaluated the parties' finances at the time of the 2016 appeal.

Sanctions (affirmed): Dennis waived res judicata by failing to raise it as an affirmative defense at trial or in his motion to reconsider. The prior denial of sanctions was not a final appealable order under Rule 304(b)(5), so the trial court retained jurisdiction.

True-up years 2017–2022 (affirmed): Dennis had adequate notice through Della's filed proposed calculations and his own responsive calculations; no prejudice resulted from the absence of separate pleadings for each year. Reviewed de novo.

Income determinations—profit sharing and travel allowance (affirmed): Dennis failed to preserve the profit-sharing issue by not objecting below; the travel allowance was properly included where Dennis failed to meet his burden of proving actual expenses. Reviewed for abuse of discretion.

Dependent child-in-care credit (reversed and remanded): Under In re Marriage of Henry , 156 Ill. 2d 541 (1993), social security derivative benefits generated by the obligor's earnings must be credited toward child support. The record showed the child-in-care benefits were attributable to Dennis's contributions. Abuse of discretion standard.

Imputation of income (reversed and remanded): The MSA unambiguously required 28% of Dennis's actual statutory net income. The motion was one to enforce, not modify, the MSA; imputation of income required a modification showing substantial change in circumstances, which was never alleged. Reviewed de novo (contract interpretation) and abuse of discretion (income determination).

Statutory interest (reversed and remanded): The MSA set no due date for additional child support—only a deadline for providing tax returns. Interest under 750 ILCS 5/505(b) applies only to past-due amounts; interest properly commences 30 days after the court sets a due date for the true-up payment, per In re Marriage of Tegeler , 365 Ill. App. 3d 448 (2006).

Legal Principles

750 ILCS 5/505(b), (d) — statutory interest on child support accrues only on amounts that are due and unpaid; a support order creates a series of judgments as of each installment's due date.

750 ILCS 5/508(a)(3) — permits attorney fee awards upon successful defense of an appeal in family law cases.

750 ILCS 5/502 — child support is modifiable only upon a showing of substantial change in circumstances.

In re Marriage of Henry , 156 Ill. 2d 541 (1993) — social security derivative dependent benefits generated by the obligor's earnings must be credited toward child support obligations.

In re Marriage of Tegeler , 365 Ill. App. 3d 448 (2006) — distinguished back child support (pre-order) from overdue child support (post-order); interest runs only on overdue amounts.

In re Marriage of Worrall , 334 Ill. App. 3d 550 (2002) — per diem travel allowances constitute income for child support, but the obligor may reduce income by proving actual travel expenses.

Blum v. Koester , 235 Ill. 2d 21 (2009) and In re Marriage of Doermer , 2011 IL App (1st) 101567 — MSAs are construed as contracts; unambiguous terms are enforced as written.

Key clarification: A court cannot impute income to an obligor under an enforcement motion when the MSA unambiguously ties support to actual income; imputation requires a modification proceeding with a showing of substantial change.

Practical Implications

Draft MSA true-up provisions with explicit due dates. Without a specified payment deadline, statutory interest cannot begin to accrue, potentially costing the custodial parent significant sums.

File separate motions to modify if seeking imputation of income. An enforcement motion alone is insufficient to impute income when the MSA ties support to actual earnings; practitioners must allege substantial change in circumstances under Section 502.

Credit all derivative social security benefits. Under Henry , dependent child-in-care benefits attributable to the obligor's earnings record must be credited, not just direct child dependent benefits. Custodial parents should be prepared to demonstrate benefits derive from their own record if contesting credit.

Raise affirmative defenses promptly. Res judicata must be raised at the trial level or it is waived—even where the same motion was previously denied.

Preserve issues on the record. Dennis's failure to explicitly object to the profit-sharing account's treatment as income resulted in forfeiture on appeal. Practitioners must make clear, contemporaneous objections.

Notice through conduct can cure pleading defects. Filing responsive true-up calculations covering disputed years may constitute adequate notice, defeating a claim of surprise. Opposing counsel should object immediately if years beyond the pleading are at issue.

Counterargument: This case could be distinguished where an MSA contains language permitting imputation or where a separate modification petition is filed alongside the enforcement motion.

Limitations/Caveats

This is a Rule 23 order and is not precedent except in the limited circumstances allowed under Rule 23(e)(1). The discussion of dependent child-in-care credits, the distinction between enforcement and modification for imputation purposes, and the statutory interest analysis are all binding holdings as to the parties but carry only persuasive value in other cases. The court's observations about notice and prejudice in the context of duplicative pleadings and true-up year coverage are largely fact-specific and constitute applied reasoning rather than new legal rules. Dennis proceeded pro se on appeal, which may have affected the quality of issue preservation and argument development.
