Hi. We are a concreting company and we quoted and won a project. However, we were unable to complete the job due to the employing company not paying on time, and not wanting to be stuck with chasing up final payments etc. They are now getting the project completed by other companies (as we expected), and they are saying we are liable for the cost to get it completed! Can they do that under contract law? I do not remember signing a contract but as I sign so many things, I can't remember. I went through paper work and I can't find a contract from them! Should I ask for the signed contract to be sent to me so I can look to see if it's in their policies? Thank you.
