Property owner is counter suing the lien inflows for non payment. How do I prepare?
No attorney is going to be able to answer your question without more information. In general, be knowledgeable about the scope of the contract, the scope of the work performed, and be prepared to prove you did what you were supposed to do. You really should consult with an attorney to help you prepare, even if you don't want to hire one to represent you in your claim.
