Contractors

We provided maintenance services on a helicopter for a company who will not pay us. We filed a lien in Blount County and with the FAA in Oklahoma. We just learned the helicopter is up for sale. Is there anything else we can do in the way of repossession, attachment, foreclosure, to prevent the aircraft from being sold. We are in contact with the financial institution who financed the aircraft. Also, we were told by others that if the aircraft was sold outside the U.S. our lien would be worthless.

In Rhode Island, can an architect file a lien on a project where he provided professional services?

What form do I use to sue an apartment complex for which I did roof repairs and still owes me $22,400.00? I filed a lien, but now I want to sue (pro se).

We are a subcontractor to a contractor doing State of California Road work. The cutoff for pay estimates for Contractor is the 20th of each month. Our suppliers pre liened the job, but they modify their statement periods for us due to the 20th cutoff for Contractor's estimate period. The contractor is requiring us to provide lien releases from our suppliers using the 30th as a cutoff date. They are writing joint checks to our suppliers paying them through the 30th, but only paying us through the 20th. Is this legal?

The general contractor forced me to sign a lien release that was for $407,000. I had only been paid $289,000 (inclusive of the subject payment). I performed an additional $150,000 of work after the date of the release. The owner fired the general contractor from the job. I filed a lien on the property for the $150,000. The Owner is now suing me stating that they have a lien release showing that I've been paid $407,000 and they are demanding that I remove my lien. Am I in the wrong? Do I have a case?
