**IMPORTANT**
Effective June 2025 (expected June 5, 2025), you will no longer log in to our online Case Manager using your old username and password, and will log in through a new MyMassGov log in. You will need to have an email address, set up new log in credentials, and relink your child support account. To make this change as easy as possible, we have added detailed instructions here. If you have any questions after reviewing the instructions, please call Customer Service at 1-800-332-2733.
