Lack. Cnty. Pa. 2056
In a case in which a defendant is incompetent, the notice required by Pa. R.Civ.P. 2056(b) may be given by personal service or by registered mail. If registered mail is utilized for this purpose, the plaintiff, the plaintiff's attorney, or any competent adult acting on behalf of the plaintiff shall send a registered letter to the last known address of the guardian of the incompetent defendant requiring a receipt signed by the guardian. If the letter is returned by the post office without a receipt signed by the guardian but with the notation by the postal authorities that the guardian refused to accept the letter, the plaintiffs shall have the right of service by ordinary mail addressed to the guardian of the incompetent at the same address with the return address of the sender appearing thereon.
