Art. 35 of Dominican Divorce Law #1306bis states the following: “A divorced woman shall not marry again before ten months have elapsed from the time the divorce has become final, unless she marries the same husband she divorced.”
As I have said, this is an exact translation of article 228 of the French Civil Code of 1804, a time when pregnancy tests did not exist and therefore confusion could result regarding the paternity of any child born soon after the new marriage.
The prohibition applies both to Dominican and foreign women, as it did in France before the prohibition was eliminated (cf. ruling of the Paris Court of Appeal dated Feb. 13, 1872).
However, a marriage done within the 10-month period is not invalid for that reason alone. The legal sanction to noncompliance consists only in the application of a fine to the “civil officer” (“oficial de estado civil”) who officiated the wedding. The fine, pursuant to Art. 194 of the Penal Code, may amount from twenty to a hundred pesos.
Thus, if you can find an "oficial de estado civil" who will marry you, go ahead. Otherwise, marry abroad.
Also, based on the purpose of the statute, the authorities should waive the requirement with the presentation of a negative pregnancy test. I'm saying "should", not that they will, knowing the ways of the bureaucrat.
