Massachusetts Deadline Rules

  • Answer to complaint: 20 days after service (Mass. R. Civ. P. 12(a)(1))
  • Mail service adds 3 calendar days to response periods (Mass. R. Civ. P. 6(e))
  • Response to motion for summary judgment: 21 days (Mass. R. Civ. P. 56(c))
  • Massachusetts legal holidays toll deadlines; next business day rule applies

You found the deadline. Now what?

The calculator is free. Drafting the actual answer, motion, or response — and tracking the deadline so it doesn’t slip — is what wins or loses your case.
