How to document everything (the right way)

Keep one timeline

One document, one line per event, oldest first: date, what happened, who witnessed it, what proof exists. No commentary. No adjectives. A timeline you can hand to a lawyer in one page is worth more than a shoebox of screenshots.

What to capture

• Every missed, shortened, or refused parenting time — with the scheduled time and what actually happened.
• Messages in their original form. Full-thread screenshots with dates visible, not crops.
• Receipts for anything you paid for the child.
• School and medical records you are legally entitled to as a parent.
• Every court order, in one folder, in date order.

What backfires

Recording your child. Interrogating your child about the other house. Recording conversations you are not lawfully permitted to record — Massachusetts is a two-party consent state and secret recording of an oral communication is a crime under the wiretap statute. It will not become evidence; it will become the thing the other side talks about.

Also avoid the giant binder. A judge who has fifteen minutes will not read four hundred pages. Curate ruthlessly.

Communication hygiene

Assume every message you send is a future exhibit. Short, factual, child-focused, non-reactive. If you would not want it read aloud in the courtroom, do not send it. Many parents move all co-parenting communication to a single written channel for exactly this reason.
