It started as a routine discovery issue. Mid-sized litigation. Tight deadlines. Standard custodians. Nothing unusual.
The legal team believed they had done everything right. Legal hold issued. Emails collected. Documents processed. Review underway.
Then opposing counsel asked a simple question: “Where are the Teams messages?”
Silence.
No one had intentionally excluded them.
No one thought they were important.
They just weren’t part of the original plan.
What followed wasn’t dramatic. There was no accusation of misconduct. No sanctions motion.
But something subtle changed. Trust. And in litigation, trust is leverage.
The Most Dangerous Discovery Failures Are Quiet
Discovery breakdowns rarely begin with bad intent. They begin with assumptions.
- “We mostly communicate by email.”
- “Chat is informal.”
- “Anything important would have been forwarded.”
But modern communication doesn’t work that way anymore. Decisions happen in chat threads. Clarifications happen in quick replies. Intent shows up in emojis. Context disappears in exports.

In this case, the missing messages didn’t contain a “smoking gun.” But they did contain tone. Timing. Reactions. Conversations that framed the email record differently. And once opposing counsel discovered the gap, the focus shifted.
Instead of debating the merits of the claim, the court began asking about process.
- How was data scoped?
- Who decided what to collect?
- When were those decisions made?
The case didn’t fall apart. But it became harder. More expensive. More defensive. The real issue wasn’t the missing messages. It was the missing anticipation.
Discovery Risk Is Usually a Planning Problem
By the time review begins, most discovery risk has already been shaped. Not by technology. Not by the review team. But by early conversations – or the lack of them.
The strongest discovery strategies start with uncomfortable questions:
- Where do people actually communicate?
- What tools are used informally?
- What data feels “secondary” but could change context?
- What might opposing counsel reasonably ask for later?
These questions require experience – not just checklists.

Because discovery is no longer about collecting obvious files. It’s about understanding behavior.
In today’s cases, communication is fragmented:
Email
Teams
Slack
Text
Shared documents
Personal devices
The legal hold may go out. But if planning doesn’t reflect reality, gaps form quietly. And quiet gaps are the ones that create strategic vulnerability.
Closing
The most memorable discovery failures aren’t explosive.
They’re subtle.
They shift leverage.
They raise credibility questions.
They invite scrutiny that wasn’t necessary.
At Sovereign Discovery, we approach discovery the way litigation unfolds in the real world – not the way policies describe it.
Because strong discovery management isn’t just about producing data. It’s about preventing the one missing piece from becoming the story of the case.
