According to the Secretary of State's Office - Citizen Information Service, there is no formal procedure for establishing a legal residence in Massachusetts. Normally tangible proof of residency is provided through:
- Voter registration
- Automobile registration
- Driver's license
- Appearance of a person's name on a city or town street list
- Rent / mortgage receipt
- Utility or telephone bills
Individual public or private agencies or institutions may have their own requirements for proof of residency.
The Secretary of State's Office has a brochure titled "Welcome to Massachusetts, a Practical Guide about Living in the State." The State's website
is useful as well.
