I owned property free and clear before marriage in '97. Husband built new building and added on to existing building. I signed a quitclaim deed to give him 50% of interest. We split (I moved out) four years ago; never completed a legal separation or divorce. He has now passed on, and did not have a will. He has an adult daughter from a previous marriage. I can't seem to get a clear answer about what to expect in WA state on how this will be divided up.
