The person in possession of escheated property shall be liable for the rent of real estate and hire of personal property, whether he claim title or not. Where the escheat is established, the court shall determine and decree rent or hire to the state, if any be due, and may make an allowance in proper cases to a party for the care of the property. In case the party in possession refuse or fail to deliver possession to the escheator who is authorized to receive the same, such party shall be liable to double the value of the rent or hire for the time he may so withhold possession, to be determined by the court on petition of the escheator. Decrees rendered in matters of escheats shall be conclusive against all parties thereto and privies, but may be reviewed by the supreme court on appeal.
