Five months after the separation, ex-husband purchased a home. I signed nothing. My attorney never addressed this issue. Before the separation, I filed a divorce from bed and board which never went to trial and was dismissed prior to ex purchasing the home. My case went to trial with this issue never once being addressed. This property was purchased in his name only prior to the divorce. What rights did I lose and is this negligence on my attorney’s part? Did I, do I have an interest in this property? Thanks.
