Persons wishing to obtain a license must be eighteen years old and file their intentions to marry with a City or Town Clerk in person (except for cases where one person is in the military or incarcerated) at least three days before the ceremony. In Tewksbury, the fee for filing for a license is $40 and $15 for certified copies. The license is valid for sixty days, and may be used for a ceremony conducted in any Massachusetts city or town. A Member of the Clergy or Justice of the Peace who performs the ceremony must sign the license and return it to the city or town where the license was issued.
