Any person who is not concluded as a party or privy by a decree in favor of the state in proceedings to establish an escheat, may, at any time within six (6) years after the rendition of the decree, recover of the state, by suit, the net proceeds derived from the sale of personal property and paid into the state treasury, and three percent (3%) interest thereon, if the party shall establish his right to the property and that the same had not properly escheated to the state; but the title of the purchaser of such personal property shall not be thereby disturbed.
