Equipment Lessor or Materials Supplier

Massachusetts has a complex lien deadline, and the actual deadline date will change depending on the specific details of your project. Generally, the deadline to file a mechanics lien in Massachusetts will be the earliest of the following dates:

1. 90 days after the Notice of Substantial Completion (if one gets filed);
2. 120 days after the Notice of Termination (if one gets filed); or
3. 120 days after the claimant last furnished labor or materials to the project.

So, to determine your lien deadline, it's important to see if a Notice of Substantial Completion is filed, or if a Notice of Termination is filed. And, if neither document is filed, the deadline will be 120 days after the last furnishing date. 

If you're looking for an exact deadline date, Levelset has a helpful tool here: Mechanics Lien & Notice Deadline Calculator. Or, using a site like timeanddate.com could help.

in regard to last furnishing date-- materials were delived awhile ago but used throughout the whole project and the project was just finished (materials were a roadzipper machine and barriers) 

So woudl it be when we furmnised them or the 120 days after the project was finished
