We did some work for a homeowner after Hurricane Harvey. We were originally working with another contractor but he backed out so we did the work ourselves. The homeowner is well aware which contractor did the work on her home. The problem is she does not want to pay and the contract that was signed is from the original contractor. The invoice and the notice of intent was sent by our company but I was getting ready to file the lien and wanted to attach the contract and realized we never had her sign one for our company to replace that one. What should I do?
