I filed a lien on a property for non-payment of the final bill. The owner "bonded off" the lien and sold the property. I received no notice so I don't know the surety name, bond or escrow number, or if the principle is the seller or buyer. How can I get this information, and how do I enforce a lien on a bond/escrow? How do I know whether it's a bond or escrow account (Alaska state law refers to "bond" for lien removal, but the only contact I've had was a call to confirm the payoff amount from an escrow/title company). Also, Alaska Law allows a property lien to be extended 6 months by filing an extension, but isn't clear whether a lien can be extended after it's been bonded.
