Hello there, I have a landscape business and I built a Pergola that the homeowners did not pay for so I filed a lien with your guys's help and I can't say thank you enough. However the homeowner says they don't want to pay because they just found out that there was no permit which they say completely voids the contract, I am currently working to get a retroactive permit. But is that true does this make the lien and contract completely void? Thank you
