You cannot be common law married to an individual who is legally married to someone else. Until the husband divorces his first wife, your family member is not common law married to him because he is married to another person. Once he divorces the first wife, she may then marry her divorced partner, but the time she has spent with him prior to divorcing the first wife does not make her common law married. She is simply dating a married man.
