I am a GC and I filed a lien against a property where I did tenant improvement work. The tenant contracted me not the owner. Now owner is asking me to give them lien release since the work done was not under contract with them. I don't want to respond to their request without knowing enough. I don't want to release my rights by mistake and let go of money I am owned by the tenant. How should I proceed.Thanks a lot for all responses. Considering the technicality of Mechanics Lien I understand that I have lost my window of opportunity to force a legal action. The amount in dispute was not large to start with so I was not planning to go that route anyways. I just want to make sure though that by not giving the building owner a lien release I am not putting my self in any legal trouble. I am sure that building owner is going to force the tenant to resolve this matter with me so they can get the lien release and that way I will get paid (or at least I am hoping for that).
