How do I file a Judgment agains a body/shop? My car is finished but he wont release it to me becuase were disputing a 25K bill

A body shop can assert a lien against a car for unpaid charges under RCW 46.71 (automotive repair act) and RCW 60.08 (chattel lien statute). A person running their own body shop falls within the definition of “repair facility” under RCW 46.71.011(3) if he does collision repair and refinishing. He has to provide a written estimate of work over $100 and obtain written authorization from the owner for work exceeding the estimate by 10%, and must post a sign disclosing customer rights. If he failed to give a written estimate, did work exceeding the estimate without written approval, or did not post the required sign, he is not entitled to assert a lien against the car. Failure to release the car without lien rights and other violations such as overbilling is a violation of the act and the owner would be entitled to damages including treble damages and attorney fees and costs under the consumer protection act. Contact a consumer rights attorney or the Attorney General's office.
