mechanics lien

[TOW'D]

Howdy Gang,
Looks like we have to use a mechanics lien to get paid on our work done on replacing the floors on the flintstone special 356 Porsche.
I still have the car and it isn't going anywhere until we are paid.
The owner said that he is going to selll the car when I asked about my fee
he said that he wasn't going to pay. He said the new "owner" would be coming up to pick up the car in April.
I don't know if the PO told the "new" owner about my bill.
So I'd like to get some offical paper work ready just in case.
I'd like to keep it simple do the work and get paid.
I think the PO must have lost a lot of money in the last stock market crash
but that isn't my problem.

Any tips
hank
