Texas Equusearch Mounted Search and Recovery helped look for her daughter Caylee from mid-July 2008 through September 2008.
Under the terms of the settlement filed last week, the agency will be allowed to have an unsecured claim of $75,000 in Anthony's bankruptcy case.
The group had objected to the bankruptcy, claiming it spent more than $100,000 during the investigation. Attorneys for Texas Equusearch Mounted Search and Recovery said Anthony knew her daughter was already dead.The Florida woman was acquitted in July 2011 on charges of murdering Caylee but convicted of four misdemeanor counts of providing false information to a law enforcement officer.
She told officers a baby sitter had kidnapped the child. Authorities late learned the baby sitter never existed.
Anthony filed for bankruptcy in Florida in January.
