I own an organizing business, one of our clients did not pay us for the work done at their home which was 2 years ago. We have sent many notices and phone calls. They are now selling their home. What would be the process of placing a lien on their property so that we can get paid? What forms are involved? If I use a lawyer do they have to be licensed in my state or can they be from out of state? The total owed to my company is over $4000.
