Tips for filling out form DE-121(MA)

When completing form DE-121(MA), pay special attention to these less obvious sections:

Address

Complete Address

Double-check that each address includes the street, city, state, and zip code in full. If any part of an address is missing or incorrect, it could invalidate the service for that particular person. Consider validating addresses with reliable sources before mailing.
Name of Person Served

Identify Accurately

Ensure that the name you list for each person served matches exactly with any legal documents or informal names they may use. Inaccurate naming can lead to delays if any challenge arises concerning adequate notice.
Numbers

List Sequentially

When listing the numbers for each person to whom notice was mailed, ensure they are sequential. This means starting from 1 and continuing in order without skipping numbers. This sequencing is important for clear reference if there are any inquiries or disputes about the notifications.
