While you should consult with a real estate attorney to see whether, in your particular situation, you have any rights, as a general matter, you likely have no rights other than possibly to be treated as a tenant (due to your payments) and not a guest, which means you have to evicted as a tenant would be, and cannot be removed at will like a guest.The problem for you is that agreements concerning the purchase or ownership of real estate must be in writing to be enforceable in your state (and most states), under the legal doctrine called the "statute of frauds." An oral (that, not "verbal," is the correct term) agreement to add you to the title--which means to sell an interest in the real estate to you--is not typically enforceable if not in writing. That you made payments does not guaranty or give you ownership--people may pay the mortgage or other expenses for a variety of reasons, such as their "rent" for living there, or as a gift to family or friends, and so the fact of making payments does not establish ownership.
