Jeffery C. Frazier v. Office of Child Support Enforcement, Jana L. Bland, and Paige E. Bland, 618 S.W.3d 415

OCSE filed a paternity action after Jana Bland assigned her daughter Paige’s child‑support rights to OCSE; DNA testing showed 99.99% probability Jeffery Frazier is Paige’s father.
Jeffery raised equitable affirmative defenses (unclean hands, laches, waiver, equitable estoppel) and sought joinder of Jana as a party; the trial court sua sponte joined adult Paige as a plaintiff despite her stated waiver.
Jana and Paige (joined) moved for summary judgment on paternity and for eighteen years of retroactive support; OCSE’s affidavit calculated arrears at $179,080.54 based on Jeffery’s admitted income (no dispute on calculation).
The trial court granted summary judgment, found Jeffery the father, ordered $179,080.54 in retroactive support, and rejected Jeffery’s equitable defenses as insufficient.
On appeal Jeffery challenged (1) the joinder of Paige and (2) the grant of summary judgment rejecting his equitable defenses.
The Court of Appeals affirmed joinder of Paige but reversed the grant of summary judgment and remanded for trial, finding genuine factual disputes on the equitable defenses.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the trial court erred by joining adult Paige as a party plaintiff	Paige (and Jana/OCSE) may pursue paternity/support under Arkansas statutes; Paige had a direct interest	Jeffery: Paige was unnecessary/redundant because OCSE (and Jana) were real parties; joinder prejudiced defendant	Joinder affirmed: statutes authorize Paige’s participation and joinder was not reversible error
Whether Jeffery’s equitable defenses bar retroactive child‑support and preclude summary judgment	Jana/Paige (and OCSE): defenses fail; paternity established; arrearage calculation undisputed	Jeffery: facts (mother’s representations, holding out another man as father, long delay) support unclean hands, laches, waiver, equitable estoppel	Reversed and remanded: equitable defenses may apply; material factual disputes exist and summary judgment was improper
Whether OCSE’s arrearage calculation was contested on appeal	Plaintiffs: calculation based on admitted income and Admin. Order No. 10 is correct	Jeffery: did not challenge math on appeal	Calculation undisputed; only liability and equitable defenses remanded
