Ohio Appeals Court Revives Inmate's Foreclosure Challenge Over $61,000 Columbus Property Surplus

COLUMBUS, Ohio — A state appeals court resurrected a convicted killer's bid to overturn the foreclosure of his Columbus home, ruling that post-auction court fights cannot retroactively cure defective legal notice.

The Tenth District Court of Appeals in Ohio ruled on Nov. 10, 2026, that lower judges erred when they blocked Mamadou Diallo from challenging how lenders notified him of foreclosure proceedings while he sat inside a state penitentiary. The dispute reignited after a court-ordered sheriff's sale left $61,060.07 in unclaimed cash on the table. Diallo is serving a prison sentence at the Southeastern Correctional Institution for the September 2021 murder of his wife, Fatoumata Diallo.

Jurisdiction comes first. A court cannot take a man's house if the bank never served him the lawsuit.

The ruling throws a wrench into a two-year recovery action waged by national mortgage lenders, sending the case back to Franklin County for a fresh review of prison mail logs and process servers.

Default Judgments Behind Prison Walls

Diallo purchased the residential property on Noe Bixby Road in Columbus, securing a mortgage through JPMorgan Chase Bank in October 2017. Years later, after Diallo entered prison for his wife's murder, loan payments stalled. Nationstar Mortgage LLC launched a foreclosure lawsuit against Diallo in May 2023, and US Bank Trust National Association subsequently stepped in as the substitute plaintiff, filing an amended complaint in June 2024.

Bank couriers ran into immediate roadblocks at the prison gates. An initial effort to deliver the legal summons via certified mail failed. A process server later testified that he delivered the summons and complaint to an intake officer at Southeastern Correctional Institution in August 2024, alongside institutional certified mail delivery records.

Diallo never answered. The Franklin County court entered a default judgment and a decree of foreclosure on Oct. 21, 2024.

The sheriff auctioned the Noe Bixby Road house on April 25, 2025. After the county cleared outstanding mortgage obligations, $61,060.07 remained in excess funds.

The Slayer Statute and Post-Sale Scramble

Trouble started when the money sat in the court registry. Diallo petitioned for the $61,060.07 surplus in October 2025. Fatoumata Diallo's estate intervened simultaneously, demanding every cent.

A county magistrate threw out Diallo’s petition without hesitation. Under Ohio’s slayer statute, individuals convicted of homicide cannot inherit or collect financial windfalls arising from their victim’s death. The magistrate awarded the entire $61,060.07 pot to Fatoumata Diallo's estate.

Yet the surplus battle alerted the inmate to the loss of his real estate. Diallo testified that he learned about the foreclosure case and sheriff's auction on Sept. 15, 2025. He moved to vacate the underlying foreclosure judgment, insisting he never received the summons or complaint and arguing the bank violated Ohio Civil Rule 3(A) by missing statutory deadlines.

In May 2026, the Franklin County court dismissed Diallo's motion. The judge decided that by showing up late to fight over the surplus money, Diallo had forfeited any right to challenge original service defects.

Appellate Judges Reject Retroactive Jurisdiction

Tenth District appellate judges shredded that rationale. Writing for the panel, the judges stressed that trial courts cannot bind property owners without securing personal jurisdiction on day one.

The judges held that participating in ancillary, post-sale cash disputes months down the line cannot wipe away a constitutional lack of notice at the start of litigation.

The appeals court stopped short of quashing the foreclosure sale outright. Instead, the panel ordered the Franklin County trial court to hold proceedings examining whether the prison delivery met Ohio statutory requirements before the bank took its default decree.
