P.R. Laws tit. 3, § 555
Resignations from office must be in writing and made as follows:
(1) By all officers appointed by the Governor, addressed to the Governor.
(2) By all the members of the House of Representatives and the Senate of Puerto Rico, whether the Legislature is in session or not, addressed to the Presiding Officer of the Legislative Chamber to which the resigning legislator belongs, through the Office of the Secretary or the Clerk. Regardless of the date of effectiveness of the resignation, it shall be final and binding after fifteen (15) days have elapsed since the date the resignation was tendered without being withdrawn. Once said fifteen (15) days have elapsed, the central directive body of the party entitled to fill the vacancy shall notify the appointment of the substitute to the presiding officer of the corresponding Legislative Chamber. Said term shall be terminal and nondeferrable. Thus, it shall not be extended into the next working day when the last day falls on a holiday. For such purposes, the corresponding Chamber shall make the necessary provisions to guarantee the full fifteen (15)-day term to the legislator that has tendered a letter of resignation to withdraw the same.
(3) By all municipal employees not appointed by the Governor, addressed to the municipal corporation of the respective municipality, except mayors, whose resignations shall be tendered to the Governor.
(4) By all other appointed officers, addressed to the body or officer who appointed them.
(5) In all cases not otherwise provided for, addressed to the Governor.
