I am a contractor. I took over an addition project from another contractor who had done a poor job with some of the framing and was fired. I did not have lien rights verbiage in the contract, nor did I supply it within the proper time frame from starting the work. My contract clearly states what work was included and clearly states the rate at which additional work will be billed. Of course there were changes and additions. For 90% of the project, I felt like I had an excellent working relationship with the owner and therefore failed to produce change orders when things came up, thinking they understood that they were asking for work beyond the contract and would be billed for it. Upon completion of the project, I produced a bill with the contract balance and additional charges. I provided a conditional lien waiver for the amount of the bill. The owner has refused to pay any of the bill unless I provide a lien waiver for the amount they want to pay which is about 30% ($4000) less than the bill. Did I lose my lien rights by failing to provide lien information at the beginning? If I provide the waiver they are asking for, can I file a lien for the rest of the bill? Does providing the lien waiver affect my rights or my chances of success in small claims court? The amount in question is about $4000, but there were a number of services I never charged for but would like to pursue if it's going to be a battle. Can I legitimately bill now for those services? It has been about 30 days from completion of all work and about 25 days from the final bill date.
