Massachusetts law defines an operating agreement as any written or oral agreement of the members as to the affairs of a limited liability company and the conduct of its business. The definition sits in Section 2 of Chapter 156C, the Massachusetts Limited Liability Company Act.[2] The statute's own words are quoted below.
"Operating agreement", any written or oral agreement of the members as to the affairs of a limited liability company and the conduct of its business.
A written agreement gives every member the same text to read. Keep the signed copy with your LLC records.
Our free Massachusetts LLC operating agreement template is a 15-page form for an LLC with one member and one or more managers. It has 31 numbered sections and three schedules. The list shows what the main sections cover.
Section 8 makes the LLC manager-managed. Massachusetts lets the operating agreement set a different arrangement than the default, which is management by the members.[1] The Member chooses the number of Managers and lists them on Schedule B.
A single-member LLC has one owner, so the operating agreement records how that one Member runs the business. Our sample names the Member as the sole equity member and sets up a Board of one or more Managers to run the business.
If another person joins as a member later, the agreement needs to change. Section 20 covers admitting additional members, and Section 27 covers amendments. For an LLC that starts with two or more members, use the multi-member version linked above.
