Can you collect palimony if you were legally married to someone else?

Palimony is based on contractual facts, where the court would like to whether there was an agreement that the parties would live together as a couple and there would be an obligation to support. These cases are not common and very difficult to succeed. I do not think that a legal marriage to another would be dispositive of a palimony determination, but it may be considered as a piece of evidence in determining what the relationship between the parties was.
