The Bristol County Board of Commisioners voted unanimously Tuesday to send a letter to Massachusetts Attorney General Martha Coakley expressing interest in pursuing litigation against Mortgage Electronic Registration Systems, Inc, commonly known as MERS, for skirting public recording laws.

MERS is a private network that is partly owned by Bank of America. The commissioners did not specify how much they are looking to recover. “It’d be really rough numbers,” said Commissioner John Mitchell. “We’d have to find out.”
