(c) If at the time of the execution of the writ of possession there is still property inside the deceased sole tenant’s residential rental unit that does not belong to the landlord then the landlord shall have the right to immediately remove and store such property for a period of 7 days, at the expense of the estate of the deceased sole tenant. If at the end of such period, a representative of the estate, who has valid documentation of such representation issued by the register of wills pursuant to Title 12, has failed to claim said property and reimburse the landlord for the reasonable expenses of removal and storage, such property shall be deemed abandoned and may be disposed of by the landlord without further notice or obligation to any party. Upon rendering a final judgment for plaintiff, but in no case prior to the expiration of the time for the filing of an appeal or motion to vacate or open the judgment, the court shall issue a writ of possession directed to the constable or the sheriff of the county in which the property is located, describing the property and commanding the officer to remove all persons and put the plaintiff into full possession.
