Signal, Auto-Delete, and Disappearing Messages: A Growing Spoliation Risk
Our guide to spoliation during a custody case covers someone manually deleting a message. This is a different and newer risk: apps and settings that delete messages automatically, by design — Signal's disappearing-messages timer, WhatsApp's auto-delete and view-once settings, and similar features elsewhere. Courts are already ruling on what happens when a party was using one of these while a duty to preserve evidence existed.
Why this is a different problem than manual deletion
Deliberately deleting a specific message looks like what it is: a choice made about that message, at that moment. An auto-delete or disappearing-messages setting is different — it can look neutral, even habitual. “I always have disappearing messages on, it's not about this case” is an understandable instinct to reach for. But the underlying spoliation doctrine doesn't turn on whether the deletion was targeted or automatic — it turns on whether a duty to preserve existed and whether the party took reasonable steps to meet it. A standing setting that keeps destroying potentially relevant messages after that duty attaches is still a failure to preserve, regardless of whether any single message was deleted on purpose.
The same principle, outside family law
These aren't family law cases — they're federal civil and employment cases. We're citing them because courts across very different contexts are applying the same spoliation principle: once litigation is reasonably anticipated, a party generally has to stop letting evidence disappear, and courts have real remedies when they don't. That principle is the same one family courts apply to a deleted text thread; it just happens that the clearest recent rulings on ephemeral messaging specifically have come out of civil dockets.
Pable v. Chicago Transit Authority (7th Cir., decided July 28, 2025)
In this employment case, the Seventh Circuit affirmed dismissal of the plaintiff's complaint as a discovery sanction under Federal Rule of Civil Procedure 37(e), after finding he had spoliated Signal messages relevant to the case — including messages lost through Signal's “disappearing messages” feature in a thread with a key witness. The court also affirmed an award of six-figure expenses against the plaintiff and his attorney. The point for this post isn't the employment dispute itself — it's that an ephemeral-messaging feature, not a one-time manual deletion, was central to a sanction serious enough to end the case.
Oakley v. MSG Networks, Inc. (S.D.N.Y., 2025)
In this case, the court found the plaintiff had spoliated his text messages and, in a July 2025 order, granted an adverse-inference instruction for trial over the lost messages and ruled the plaintiff liable for the defendant's attorney's fees and costs incurred pursuing them. The magistrate judge overseeing the fee determination then ordered the plaintiff to pay $642,337.65 in attorney's fees and costs in an October 31, 2025 order — a six-figure consequence flowing directly from lost text messages. As with Pable, this is a civil case, not a family law dispute, but it shows the same principle playing out with a specific, verifiable dollar figure attached: courts are willing to make the cost of lost messages concrete and substantial.
The practical advice
Once you reasonably anticipate a custody dispute, turn off auto-delete and disappearing-messages settings for any conversation that could become relevant — proactively, before anyone asks, not after a request for production arrives. If a co-parenting or family conversation has been running with Signal's timer on, WhatsApp's auto-delete enabled, or a similar setting active, that's worth revisiting the moment litigation becomes a realistic possibility, the same way you'd stop manually deleting messages at that point. The two federal cases above suggest courts are not going to treat “that's just how I have the app configured” as a meaningfully different excuse than deleting messages by hand.
Where this leaves Verity's role
Verity can only analyze what still exists in an export. It has no way to recover or detect messages that were never preserved in the first place — an auto-deleted message that's gone from the platform isn't something any analysis tool can reconstruct after the fact. That's exactly why the preservation question has to be handled before the analysis step, not after: turning off disappearing messages once a dispute is on the horizon protects the record you'll eventually export and analyze, not the other way around. For the related question of what happens once something is already gone, see can deleted text messages be recovered, and for the general legal exposure of deleting messages manually during a case, see deleting text messages during a custody case.
This is general information about a legal doctrine and about two specific federal court rulings outside the family law context, not legal advice. Whether a preservation duty had attached at a given point, and what a family court in your jurisdiction would do about auto-deleted messages, are fact-specific questions for a court to decide. Verity is a forensic and behavioral analysis tool, not a law firm. If you're unsure whether an auto-delete or disappearing-messages setting could create a problem in your case, talk to a family law attorney about turning it off before anything is lost, not after.
