A demand letter was received from the contractor on a project that we've filed a mechanic's lien on. They mentioned that a Trade Contract Agreement was signed that obligates us to keep the property free and clear from all liens. By filing our mechanic lien for work that was unpaid, we have breached this agreement and need to remove the lien within a certain time period. If not, they will proceed with discharging the lien themselves, either by payment or bond, and deduct from any payment that is owed to us. Does a contractor have that ability to remove the lien themselves by filing a bond?
