I am an Auto Mechanic and I own the business. I am just barely getting my business license. I have a customer who is not paying. I did not know about the 20 day preliminary form so I never mailed one. Am I still able to get a lien on this vehicle? Also am I required to send out the 20 day form? If so should I just sent one out for every customer I get? Also will it matter that I did not have a business license at the time of the repairs? Thank you for your time.
