bought vehichle from private seller have not recieved title

[joker21]

I bought a vehicle from my mother a few years ago and have tried my best to get the title to the car. but something always comes up. when she sold the car to me the title was in the bank with a loan on it and I was told I would get the title when it was no longer in the bank. I have recently found out that its not there anymore and it's in her possession since then I have visited her trying to get the title but still have not received it. in a few months I will be moving out of the state and this is the only car I own I know I am only allowed so long without changing my tags and license but without the title im out of luck and have no idea what I can do I can keep tying to get the title but I know I wont see it for many reasons it would be nice to know what I would be able to do.
