P.R. Laws Ap. tit. 32A, § III, Rule 4.8
Proof of service shall be made by the process server and filed with the court within the term to appear granted to the person on whom process was served. If service is made by a marshal, his proof shall consist of the corresponding return; and if made by another person, proof of service shall be made by affidavit. If service is made by publication, the same shall be proved through an affidavit made by the newspaper’s manager or authorized agent, together with a copy of the notice and with an affidavit stating that a copy of the summons and of the complaint were mailed. In the cases where process is served under Rules 4.5 and 4.7, defendant’s return receipt will also be presented. Failure to make proof of service shall not affect the validity of the service. The sworn acceptance or waiver of the defendant, or his appearance, shall make said proof unnecessary.
