My Client lives in Italy, but has a local business address and local bank account She has leased a 2100 sf space in a major shopping mall to establish a retail shoe business She hired me to create drawings for the remodeling and improvement of an existing space at the Mall I completed all the drawings for my Client who than used them to get bids from Contractors She has paid me only 1/3 of my fee, prior to my completing the Contract Documents After several weeks of waiting for payment on invoices sent to her, and which she agreed to pay and stated several times that she was sending payment, she has since stopped communicating with me I sent her a "Breach of Contract" notice along with several invoices in which I demanded immediate payment for work completed to date via email She has refused to communicate with me via email, phone or texting I have a signed agreement with her that she reviewed and signed in Italy after a trip here to Los Angeles to sign her lease with the Landlord of the Shopping Center I want to recover my Fees, so do I have a right to Lien her business, business assets and/or her local 'bank account'? The amount that she owes me is $10,500 + interest of several months @ 1.5% every 15 days past due
