Miss. Code Ann. § 29-1-115

Whenever any forfeited tax land patent has been issued by the state for a period of at least ten (10) years, and the patentee has paid into the state treasury the price fixed by the land commissioner, and all taxes accruing and payable upon the land described in such patent subsequent to the issuance thereof have been paid, it shall be presumed that in the procurement of such patent the patentee paid a valid, legal, and adequate consideration therefor, complied with all the requirements of law, and practiced no fraud upon the state, and that such patent is a valid and legal patent; and said state shall thereafter be forever precluded and estopped from questioning the validity of such patent.
