A Sheriff’s deed is a deed that gives ownership rights in property bought at a sheriff's sale. A sheriff's sale is a sale conducted by a sheriff upon order of a court after a failure to pay a judgment. Often, property that is involved in a mortgage foreclosure is subject to being sold at a sheriff's sale. In such cases a sheriff’s deed refers to the deed given in foreclosure of a mortgage. Generally, the debtor has the right of redemption of the property until confirmation of sale is signed by the judge and filed by the court. The giving of the deed begins a statutory redemption period.
A sheriff's deed was prima facie evidence that the provisions of the law in relation to the sale of the property for which it was given were complied with. [Morey v. Brown, 305 Ill. 284, 286 (Ill. 1922)]
