Rhode Island General Laws Title 33. Probate Practice and Procedure § 33-19-22. Validity of sale as against claimant adverse to decedent or ward

If the validity of a sale is drawn in question by a person claiming adversely to the title of the deceased or of the ward, or claiming under a title that is not derived from or through the deceased or the ward, the sale shall not be held to be void on account of any irregularity in the proceedings, if it appears that the executor, administrator or guardian was authorized to make the sale by a court of competent jurisdiction, and that he or she accordingly executed and acknowledged in legal form a deed for the conveyance of the premises.
