¶20. In Department of Human Services v. Ray , 997 So. 2d 983, 985 (¶1) (Miss. Ct. App. 2008), MDHS appealed the chancellor's order directing MDHS and the natural mother to reimburse the non-biological father for past-due child support. On appeal, this Court reversed the chancellor's judgment, explaining that because the payments vested in the child once they became due, the father "was not entitled to reimbursement absent a showing of fraud."
