Social Security program in the United States. In Colorado, which is typical, "Any person who has cohabited with another person to whom he is not legally marriaged in the good faith belief that he was married to that person is a putative spouse until knowledge of the fact that he is not legally married terminates his status and prevents acquisition of further rights." Section 14-2-111, Colorado Revised Statutes. Putative spouse status is a remedial doctrine designed to protect the reasonable expectations of someone who acts on the belief that they are married, and generally entitled a putative spouse to the rights a legal spouse would have for the period from the putative marriage until discovery that the marriage was not legal. It is possible that a person could have both a legal spouse and someone as a putative spouse, as when a person remarries, not realizing that the divorce decree had not been made final for their original marriage; in which case, courts are directed to do what seems appropriate in the circumstances. Unlike a common law marriage, which is possible only when both spouses are legally eligible to marry, putative spouse status can be unilateral. For example, if a husband is married, but goes through a marriage ceremony without informing the woman with whom he goes through with the ceremony of that fact, the husband is not a putative spouse, because he knows that he has no legal ability to marry. The wife however is a putative spouse because she in good faith believes that she is legally married, and has no knowledge that she is not legally married. In the example above, the putative wife who believed she was married could seek the property division and alimony awards that a legal spouse could have, when the putative spouse discovers that she is not legally married, but her husband could not seek a property division in the putative wife's name or alimony from her, because he knew that their marriage was not legal. If, on the other hand, the husband had had reliable but incorrect information that his first wife was dead, both the husband and the wife would have the status of putative spouse.
