Hello, my husband and I have our own small construction business (C-8 Concrete). After doing a small concrete installation for a contractor for an apartment complex here in California Hayward, we have not gotten paid since October 2019. Because of this particular incident that has not been resolved, I have been educating my self on the pre-liens. I wanted to know If we can include the pre-lien notice on the contract in the future with general contractors and residential home owners that hired us or do we have to mail them to them? Thanks, Zaazil
