P.R. Laws tit. 31, § 232a
After dissolution of the marriage for whatever cause, man and woman are apt to remarry at any time.
Notwithstanding, to the end of facilitating the determination of the paternity, the woman whose marriage has been dissolved and who is prepared to remarry before the lapse of 301 days from said dissolution shall present to the person authorized to perform the marriage a medical certificate showing whether or not she is pregnant.
This certificate, if positive, shall constitute presumption of paternity of the spouse of the dissolved marriage.
If the woman has given birth before the said 301 days, it shall not be necessary for her to present such certificate to remarry.
