We have a 6 unit townhome, which 3 of those are owned by one individual. This individual decided to do yard work last summer and didn't notify any of the other owners. The HOA president (our neighbor) let us know Bruce is charging each unit $1,000 to cover the expenses. Our HOA is supposed to be a 3/4 ruling for any work. My husband and I are refusing to pay because we were not aware of this work or expense, nor was anyone else. This owner is now saying that he will put a lien on our property if we do not pay. Is he able to put a lien on our property based on lies, and no agreement?
