Gathering proof is only half the battle. Whether a judge will actually use it comes down to a few gates — and most evidence that gets thrown out fails on basics people never think about, like a folder of screenshots nobody can vouch for. Here's what has to be true for texts, call logs, or a recording to make it in.
Three questions decide it: Was it legal to get? Is it really what you say it is? And is it hearsay? Clear all three and your evidence has a real chance. Miss one and it can be worthless — or worse, a problem for you.
Gate 1 — Was it legal to get?
This is the gate people skip, and it's the one this site is built around. A recording made illegally — secretly taping someone in an all-party-consent state, tapping a call you're not part of, planting spyware on someone's phone — is often inadmissible on its face, and it can expose you to criminal charges and civil liability. Winning the authentication and hearsay fights doesn't matter if the evidence was unlawful to collect in the first place.
Whether your recording was legal depends on your state's consent rule (and federal law on top of it). Check it before you rely on anything: surveillance & recording laws by state, and the plain-English can I record my spouse? guide. The cleanest evidence is the kind that was lawful to gather from the start.
Gate 2 — Is it authentic? (FRE 901)
Before a judge considers your evidence, you have to show it's genuinely what you claim — real and unaltered. This is authentication, and it's where most digital evidence quietly dies. The rule of thumb (Federal Rule of Evidence 901, which most states mirror) is that you need enough to "support a finding that the item is what you say it is." For texts and call logs, judges typically look for:
- Who and when — the numbers involved and reliable date/time stamps (not dates you typed in later).
- Completeness — a full, continuous thread, not a cropped screenshot that could be hiding context.
- Integrity — some basis to believe it wasn't edited after the fact: how it was captured and stored.
- A witness — usually you, able to explain how the record was made and kept.
A pile of screenshots with no way to prove they're genuine and complete is the classic loser here. A record captured at the moment it happened, time-stamped, and stored so it can't be quietly altered is far easier to get in.
Gate 3 — Is it hearsay? (FRE 803(6))
A message is often an out-of-court statement. If you offer it to prove that what it says is true, the hearsay rule is in play and it's generally excluded — unless an exception fits. The three that usually carry the day:
- It's the other party's own words. A statement by your opponent is generally treated differently from hearsay — their own text can come in against them.
- It's not offered for its truth. Sometimes a message matters simply because it was sent — to show a threat was made, or that someone had notice — regardless of whether the content is true.
- It's a business record (FRE 803(6)). Records kept in the regular course of a business, made at or near the time by someone with knowledge — like a phone carrier's call log — can come in despite being out of court, usually backed by a records custodian.
What a judge actually weighs
- Reliable timing — trustworthy timestamps, not dates added later.
- Completeness — the whole conversation, so nothing looks cherry-picked.
- A clean chain — a clear account of how the record was made and kept, with no sign of tampering.
- Relevance and proportion — evidence tied to the actual issue, not a data dump.
How to keep evidence usable
Get it lawfully first · keep the complete thread, not screenshots · preserve the originals untouched and work from copies · keep timestamps and metadata intact · hand it to your attorney early, so authentication and any custodian declaration can be arranged before the hearing, not during it.
Edit, annotate, or "clean up" the source record · rely on cropped screenshots · collect it in a way that breaks recording, wiretap, or privacy law · assume "I have it" means "I can use it."
This is exactly why people hire a licensed investigator for the serious stuff: a professional documents lawfully and preserves it the way courts expect, so it survives the fight instead of getting tossed on a technicality.
Get this handled the right way
Know what's legal where you are, then connect with a licensed professional who documents evidence so it actually counts.
