if you are in england, find a local solicitor who deals in family matters. a quick google should point you in the right direction. a consultation will cost around 140 notes, and could be the best 140 nicker you've spent for a while. you may need some advice from an online thai lawyer as well, probably cost around 5000 baht, for advice only, there is a pinned topic on this forum.. somewhere. search for 'thai law' on the search bar... if you can't find it let us know and i'll have a lookie for the link. the england solicitor should be your first step though, they'll need your wives name, maybe ID to check there's no conlict of interest.
