Depends on your circumstances. Did you give up work to stay at home with your son or in order to 'make a home' for you and your family, and, as a consequence of that, did your career or financial prospects suffer? Or iare you in some way disabled or prevented mentally or physically, whether because of your age or otherwise, from making your own money? If the answer to either these is yes, and someone would prudently state your wife is wealthy, then sure, make a claim. If the answer is no, think twice. Remember litigation is a gamble- can you afford to lose?
