Contractors

If we release a lien on a property, can we later put a lien on it again if needed?

I hired a man who has a side construction business to do work on my house. The job was delayed by over 2 months, which kept me from having tenants move into the house. It was also shoddy work, so I kicked him out of the house and had to have someone else come in to fix part of the work and have them finish what was started. The contractor is now suing me for payment and I am refusing to pay for the labor. I did pay for materials up front. I know in Arizona, you must be a licensed contractor to sue for payment, so is this the case in Indiana as well? The man is not a licensed contractor, so I'm wondering if I can have the case dismissed due to this fact or what my options might be?

We started an addition on our house in May 2008, It was supposed to be completed in 3 months time. Our contractor just finished first week of December. He came to collect the final payment, we withheld $500.00 because we did not have the CO. We told him when we get the CO we would gladly give him the money. He finally got our CO and we were going to give him the 500.00 and he refused it saying that we owed him an additional 6500.00 for a cash discount he gave us for paying in cash. Also he now is claiming that he did 3500.00 in work that he did not charge us for and now wants that money too. He has threatened to put a lien on our house for this. We have paid all of our installments and have receipts to that effect. Any adders have also been paid and have the receipts to that effect. What recourse do we have?

I live in Georgia and hired a Pool contractor to build an in-ground pool. He, in turn, hired several sub-contractors. I have paid the contractor the full contract price plus cost for some change orders. The work was completed around June 30, 2008. I recently received a notice that the plaster company was filing a lien against my property for failure to be paid by the pool contractor. On 10/25/08 the plaster company came out to take some pictures and I asked them to take a look at a rust spot where the re-bar was rusting through. They repaired the spot and have the project finish date as 10/25/08. What constitutes the 90 day period from completion of the project? My understanding is contractors must submit lien notices within 90 days of project completion. The pool contractor is filing bankruptcy.

A contractor is refusing to sign a lien waiver that we discussed in the original agreement. At what point can I insist to get the waiver? Can I hold final payment until he signs the waiver?
