I have clients who have used and recommended the following:
MASSACHUSETTS: Deed only:
PCS Title -- (800) 973-3316
Timeshare Title, Inc. -- (866) 347-1061
InterCity Escrow -- (925) 734-9900
Full:
PCS Title -- (800) 973-3316
InterCity Escrow -- (925) 734-9900
You will want to verify that they use a Mass attorney for deed prep.
