Take the advice of electric eagle!
If you belong to an Association, contact the assoc. lawyer NOW
Don't wait... if the projects are "closed" you may be to late.
Get the liens filed, talk to a lawyer.
I had a commercial GC that I worked with for ten years, he paid his bills for 9 1/2 years very promptly. Well, that last six months was HELL. He went belly-up, and I got hosed for 19.5K. After 2 years, his estate paid $3400.00 as it was all that was left.
We live, we learn....
Payment schedules must be adheared to, if not, we walk... The tough one is the last,
NJ Law states "Do not pay "final" payment to Contractor until final inspection and approvals".
Good luck!
