(b) If an affiant or personal representative of the deceased sole tenant’s estate presents the landlord with valid documentation issued by the register of wills evidencing such representation pursuant to Title 12, the landlord still retains the right to initiate at any time an action for summary possession and/or moneys due, in which case the landlord shall bring the action against the estate of the deceased sole tenant and serve the complaint upon the affiant or personal representative at the address provided by the affiant or personal representative and, if no such good address is provided, then to serve the complaint upon the register of wills in the county in which the residential rental unit is located. If an affiant or personal representative of the deceased sole tenant’s estate does not present the landlord with valid documentation issued by the register of wills evidencing such representation pursuant to Title 12, the landlord must serve the register of wills in the county in which the residential unit is located in order to bring an action for summary possession to obtain possession of the residential rental unit and moneys due, if any. Anytime the register of wills is to be served as a registered agent for an estate, prior to initiating the action, the landlord must place a notice of such action in a paper that is circulated in the county in which the residential rental unit is located. The notice must identify: the name of the landlord; the name of the deceased sole tenant; the residential rental unit address; the type of action to be brought; the court in which such action will be brought; and the amount of the claim, if any.
