I had a contractor do some outside painting for me and it was bubbling and not scrapped and sanded properly. he fixed some of the areas but I refused to pay him unless they were all corrected. He then said he would put a lein on my property and I said I would sue him then. Well I received a lein notice in the mail the other day from him. In the notice it states that a copy of this had to be delivered to me in person or by certified mail. Does that mean it is voided?
