From a former post:
There is no such thing as a "common law" wife in the Dominican Republic. Living together with a woman is never equivalent to a normal marriage.
However, certain provisions in the Labor Code, the Minors Code and the Criminal Code acknowledge that living together has legal consequences. For example, a worker has the right to a few days off work if his concubine gives birth to his child; domestic violence to a concubine is treated the same as domestic violence to a wife. Recently, on October 17, 2001, a Supreme Court decision gave a surviving concubine the right to sue for the wrongful death of her companion in an automobile accident under very restrictive conditions: a) the couple must have lived as if they were husband and wife, in a public relationship, not hidden or secret; b) the relationship must be stable and long-lasting; c) the relationship must be monogamous and non-adulterous since its origins ; and d) the couple should be of different sexes. The ruling goes on to say expressly that "marriage and extra matrimonial companionship are not . . equivalent realities?.
