My company usually does work in apartment buildings and is not required to provide pre-construction notices. However, we are currently owed money by a real estate agent for work done at a single-family home that is for sale. She has stopped answering our calls and emails. I think I have determined that we waived our lien rights because we failed to provide her pre-construction notice, as required by A.C.A. 18-44-115. Does this in any way affect my right to sue the real estate agent for applicable causes of action?
