Quick guide to understanding Massachusetts citations

The information below is a "quick and dirty" guide to common Massachusetts citation forms and what they mean. In most cases, they are not the proper forms for citing sources in a legal document. These will help you read, but not write, Massachusetts citations.


Citations to Massachusetts laws will typically look like 1 of the following:

M.G.L. ch.93A §1 (Official set)
M.G.L.A. ch.93A §1 (Thomson/West)
A.L.M. ch.93A §1 (LexisNexis)

All of these refer to Massachusetts General Laws, chapter 93A, section 1. The different abbreviations simply refer to the same laws published by different companies.


The most common case citations are to Mass. Reports, Mass. Appeals Court Reports, or the Northeastern Reporter. These look something like this:

Tyree v. Keane, 400 Mass. 1, 507 N.E.2d 742 (1987).

This refers to volume 400 of Massachusetts Reports, page 1 or volume 507 of Northeastern Reporter 2d, page 742. The same case is found in those 2 locations. The Mass. citation is the "official cite," the NE2d citation is the "unofficial" citation. When sources talk about "parallel" citations, they mean different citations to the same case. This is the same case appearing in 2 different books. The unofficial reporter includes some additional editorial content, but the text of the case itself is exactly the same as in the official.

Comm. v. Thomas, 19 Mass. App. Ct. 1, 471 N.E.2d 376 (1984)

Similarly, this refers to volume 19 of the Massachusetts Appeals Court Reports, page 1 or volume 471 of Northeastern Reporter 2d, page 376.


Usually, references to Massachusetts regulations will look like:

102 CMR 2.00

This is Title 102 of the Code of Massachusetts Regulations, section 2.00.
