Not sure if this applies in the DR, but if you put the Asset into a Corp ownership. ( of course you need to maintain the Corporation then, which may not be worth it for you) but ANY asset in a Corp Name is UNtouchable .. by a spouse or anyone, and especially if you have your other Family members own shares in that Corp.. and esp if they own over 51% ..
When a law suit is made against a person it names any corporations owned by that person.
