You would have two choices. First go to her and point out that you are sorry but the law does not provide for a live in girl friend to be entitled to any property and you want her to turn it over [what of furniture, etc.]. If she does not believe you, go to an attorney to get a quick, [should spend much less than one hour for a letter to tell her] letter to try to convince her. If that does not work, file for a Will-less probate to get title transferred to you [beware that she might try to sell the vehicles but since she does not have a pink registration slip she should not be able to sell them]. That takes some time and money. In California you can file for a small estate probate. Get some book written for lay people, such as Nolo Press in Berkeley, Ca., and read what is involved. It may not be worthwhile to get all three back.
