Founded in 2020, Community Legal Services, Inc. (formerly known as Chelsea Legal Services) is the first and only Chelsea-based grassroots legal services agency established to provide legal services to the disenfranchised, economically disadvantaged, disabled, and elderly residents of Chelsea, Massachusetts and surrounding areas regardless of income level or immigration status.
As a 501(c)(3) organization, we are funded through grants and donations. The organization is supported by a team of volunteers and part-time attorneys who are all committed to helping the residents of Chelsea, MA and our neighboring communities.
Our mission is clear: We are here to promote equal access to legal justice for all!

About Our Services

Although we began our journey supporting the residents of Chelsea, Massachusetts, as of Spring 2021, CLS has received funding to expand our efforts to help under-served residents in Revere, Massachusetts as well. We hope to broaden our services to include other local communities in the near future.
We are dedicated to helping as many people as possible with our limited resources. Even if you do not quality for our services, we will do our best to offer referrals to other organizations that can help.
All information shared with CLS is private and confidential, regardless of whether you are eligible for our assistance or not.
