Hi, I’m an artist in Tucson AZ, and my partner and I painted a mural for a women’s retreat here in town. We wrote up a contract and the person who hired us read and signed it. We had a number of protections in there, one being that we had to be paid in full within 30 days of completion. We were supposed to be paid $500 on April 30th, but the person in question continues to delay payment. The problem is, he is renting the property, he is not the owner. Can I file a materialmens lien for this?
