Halloran & Sage represented the seller of a business foreclose on its security interest in the business’s property following a default by the buyer on a promissory note that had been issued in an asset sale. Partner James Maher and associate Casey O’Connell applied the client’s statutory protections under Article 9 of the Uniform Commercial Code to properly effectuate a strict foreclosure of the collateral, and also helped the client to exercise remedies available to it under a lease of real property that had been granted to the buyer.
