I would love to help you, but your question is really confusing to me.
So far, it sounds as though you bought a mobile with an expired registeration. Is that correct?
And is it a mobile that "lives" in a mobile home park, or is it a motor vehicle?
I'm looking forward to helping you - I appreciate that you are a return customer and "accepted" answers in the past.

Sure, it'll be legal, and it will serve as proof of purchase. You can even take a picture of the signing ceremony, in front of the home.
You can then apply for a lost title. (You didn't tell me whether it's a mobile home or motor home, so I'm guessing here that this applies): http://www.nydmv.state.ny.us/regtitle.htm
