What it means
A company expects a contract dispute and normally deletes chat messages after 90 days, so its legal team may direct relevant employees and IT staff to preserve specified messages and files rather than let the routine cycle run. A US federal court discovery handbook explains that electronically stored information relevant to pending or reasonably anticipated litigation may need preservation, with scope determined case by case.
This is US guidance, not a universal trigger for every jurisdiction, and an American Bar Association practice article on preservation planning is no substitute for counsel applying the facts. Define the matter so the hold identifies the dispute or investigation without sharing sensitive details beyond those who need them, because an unclear notice can cause both under- and over-preservation.
Identify custodians, who may include employees, former staff, contractors and outside service providers, and identify sources such as email, chat, cloud drives, phones, databases, logs, backups and paper records. Avoid assuming one central mailbox has everything.
Set a reasonable date range and subject scope with counsel, because preserving every record forever can be costly and obscure relevant evidence, while a narrow scope can lose material information. Pause deletion mechanisms such as retention schedules, auto-delete rules, device replacements and account offboarding, which can remove data without anyone pressing delete.
Coordinate these technical controls with IT. Tell custodians what to do with a clear notice identifying covered material, preservation steps, questions and a contact, and keep evidence that it was received and understood.
Do not edit, rename or selectively clean up a document because it might look bad, and preserve relevant context and metadata as required by the plan. Preservation does not mean making every document available to everyone, so access and legal privilege need separate controls.
If files are later copied for review, record source, time, method and chain of custody where appropriate, since a loose folder of screenshots may be incomplete. Monitor new information, as the hold may need expansion when new claims, people or systems emerge, and check third parties such as a cloud provider's retention settings or a departing vendor.
Follow up with periodic reminders and audits, because custodians may change roles or forget the scope. An illustrative hold inventory could list ten systems, eight with confirmed retention controls and two awaiting verification, which is an 80% control-confirmation status, not 80% legal compliance or proof that all relevant data is saved.
Counsel should document why data sources were included or excluded, and release should be deliberate, since a case milestone alone may not end every related hold. Watch overlapping holds, because releasing one should not delete material still preserved for another matter; a legal hold is a managed exception to normal disposal, not just an email saying "save everything."
In practice
Real-world examples.
Example
A legal team at a software company pauses auto-deletion of relevant contract messages during a dispute. IT switches off the 90-day chat purge for the named channels and confirms in writing. Ordinary deletion continues for everything outside the hold.
Example
An employee of a logistics firm leaves during an active hold. HR and IT keep the employee's laptop image, mailbox and shared-drive files instead of wiping the device, as the usual offboarding process would. The files stay preserved until counsel releases them.
Example
A hospitality group closes one case and releases its hold, while a second overlapping hold remains active on the same booking records. Counsel checks which files fall under both matters before any deletion is permitted. Shared material stays preserved.
Formula
Calculation
Illustrative operational status = systems with confirmed preservation controls / systems identified in scope x 100.
Worked example. An invented hold lists 10 systems in scope, and 8 have confirmed preservation controls. Status = 8 / 10 x 100 = 80%. The 2 remaining systems, perhaps a departing vendor's portal and a set of employee phones, still need verification before anyone can say the inventory is fully controlled.
This is an operational tracking figure only. It is not legal compliance, and it says nothing about whether the right systems were identified in the first place.Case study
Seen in the real world.
This entirely fictional example follows Crest Components, an invented parts maker. After a supplier dispute arose, counsel identified email, purchasing chat and shared-drive records. IT paused relevant deletion and confirmed the hold with named custodians. A later claim from a second supplier expanded the scope to include warehouse scanning logs.
Counsel recorded why each source was added, and IT updated its controls. When the first dispute ended, release required counsel review because the second matter still covered some of the same records. The case does not define a universal legal trigger.
Watch out
Common mistakes.
- Assuming a notice alone stops automatic deletion across every system.
- Destroying or editing potentially relevant records after learning of a hold.
- Ending preservation after one milestone while another related obligation remains.
