My wife's father (who lives in FLA) suffered a number of strokes 8 years ago, after which, his wife assumed all the financial and medical decision-making in their household, she has positioned herself with all of the control. Recently, he has discovered that she has been (possibly) having an affair with someone and to make a long story short, he wishes to seek a divorce. My wife and I live in Canada and are happy to give him a home should that be what he wishes, but we are concerned with all of the issues that will inevitably arise once he decides to leave his wife of 30+ years. We have no experience with this type of situation, and with the legal systems of two countries being in play, what avenues are open to us? He's extremely unhappy and my wife only wants him to be as comfortable as he can be for the time he has left, but going into this, we know that his wife will fight any moves we make.
