I'm a GC and worked on a condo remodel. Finished the job and owner has only paid half, after receiving the invoice. We only had a verbal agreement and I did not file a preliminary notice of lien 60 days after the job started. I have tried working out a payment plan with her, or her only pay half of what's left. But the owner is unwilling to settle. So, I feel like I could put a lien on her condo until she pays what she owes. But I am not sure it will work if I never filed a preliminary notice. And I don't want to spend the money on filing the lien if the owners lawyer can get out of paying it, by saying I didn't not file proper forms. Thanks
