Changing phones during a lawsuit can create an evidence problem even when the replacement has nothing to do with the dispute. An upgrade, broken screen, or trade-in offer may lead someone to erase a device before checking whether important records have been preserved.
The concern extends beyond the messages visible on the new phone. Attachments, older conversations, account information, and details needed to explain a record’s origin may require attention.
This guide focuses on U.S. civil cases. State rules, court orders, and the circumstances of the dispute can affect what must be kept and how.
Preservation Can Matter Before a Case Is Filed
Federal Rule of Civil Procedure 37(e) addresses electronic information that should have been preserved in anticipation of litigation or during a case. Waiting for a lawsuit, subpoena, or request for the phone can therefore be too late.
If a serious dispute is developing, ask a lawyer when preservation obligations begin and which records they cover. Share any demand letters, preservation notices, discovery requests, or court orders.
Explain the planned device change early, including any deadline to return the old phone. That gives counsel time to arrange an appropriate preservation method.
Identify the Records Connected to the Dispute
Begin with the issues in the case. An employment dispute might involve work messages and schedules, while a property dispute could involve photographs, contractor communications, and payment records.
Prepare an inventory of relevant apps, accounts, people, and date ranges. Include records that may be unfavorable as well as those that support your position.
Also identify other devices or accounts where related material may exist. A tablet, work account, or older phone may contain information absent from the device you currently use. Identify only sources you lawfully control; ask counsel about obtaining records held by someone else.
The inventory helps your lawyer define the preservation task. It is not an instruction to collect every item on every account indefinitely.
Screenshots May Leave Important Gaps
A screenshot captures a particular view. It may omit surrounding messages, attachments, dates outside the visible screen, or information about the sender’s account. A saved contact name also does not necessarily establish who sent a message.
One federal court’s analysis illustrates the problem: a party took screenshots of selected communications but later discarded a phone containing other relevant information. The court found that the limited collection did not satisfy her preservation obligations. That finding depended on the circumstances of that case.
Screenshots can still be useful. Keep them unaltered and discuss whether the underlying conversations or files also need preservation. Federal Evidence Rule 901 generally requires sufficient evidence that an item is what its proponent claims it is; it does not impose a universal ban on screenshots.
If you need to highlight or explain something, use a separate working copy.
Check What the Backup Actually Contains
A successful backup notification does not establish that every relevant record is included.
For example, Apple explains that iCloud backups exclude certain information already synchronized with iCloud, including photos and messages when their respective synchronization features are enabled. Computer backups also have exclusions. Relevant material may therefore be spread across a backup, cloud account, and individual applications.
The practical implication is to verify coverage rather than relying on the word “backup.” Ask whether the preservation method includes the needed date range, attachments, and account details, and whether the resulting files can be opened.
A useful hypothetical: recent messages appear on the replacement phone, but an older conversation and its attachments do not. The transfer may be adequate for everyday use while leaving an unresolved evidence gap.
Review Automatic Deletion and Account Access
Check whether relevant apps use disappearing messages, retention periods, or automatic cleanup. Tell your lawyer about those settings and ask how to prevent further loss while documenting any changes.
Do not assume disabling a timer restores material already deleted. Likewise, keeping the physical phone may not resolve every issue when records are held in an online account.
Before changing phone numbers or closing an account, identify how you will maintain authorized access to the accounts involved. Consider authentication prompts, recovery information, and employer-controlled access. Avoid making unnecessary changes to relevant accounts until the preservation plan is clear.
Arrange Preservation Before a Trade-In or Repair
Tell the lawyer whether the old device will be returned, sold, repaired, recycled, or kept. These are different situations, and a repair shop may need to explain whether its proposed work involves erasing data or replacing the handset.
Before releasing the device:
- Confirm the agreed records have been collected and checked.
- Ask whether the original phone must also be retained.
- Record the device’s identifying details and the date and purpose of any handover.
- Keep repair authorizations, trade-in receipts, and relevant service correspondence.
Do not assume that a lawyer needs a full forensic examination in every case. Where specialized collection is appropriate, NIST’s mobile-device forensics guidance describes preservation, acquisition, examination, and reporting as distinct parts of the process.
Ask the specialist how to handle and store the device. Experimenting with recovery software or repeated resets can complicate the task.
Preserving Data Does Not Automatically Require Full Disclosure
A phone may contain confidential work material, medical information, private conversations, and communications with a lawyer. Preserving relevant evidence does not itself authorize unrestricted access by the opposing party.
In federal civil cases, Rule 26 generally limits discovery to nonprivileged information relevant to a claim or defense and proportional to the case. Courts may also issue protective orders for good cause.
Have your lawyer address collection scope, privilege review, appropriate redactions, and secure transfer before production. Comply with applicable deadlines and orders while those issues are resolved. Privacy concerns should be handled through the legal process rather than by deleting potentially relevant material.
If the Phone Has Already Been Reset or Lost
Tell your lawyer promptly and describe what happened as accurately as possible. Include the date, reason for the replacement, backup history, and whether the old device may still be available from a repairer or trade-in provider.
Preserve remaining copies and related correspondence. Counsel can consider whether equivalent information exists in another authorized account, on another device, or through discovery from another person.
Do not recreate missing conversations and present them as original records. A written recollection should be clearly identified as a recollection, with uncertainty acknowledged.
Before attempting recovery or restoring an older backup over current data, obtain guidance. The next step should account for both the missing material and the records that remain.
Losing Data Does Not Automatically Decide the Case
Under federal Rule 37(e), the court considers whether information that required preservation was lost through a failure to take reasonable steps and whether it can be restored or replaced through additional discovery.
When that loss prejudices another party, the court may order measures limited to addressing the prejudice. The rule’s more severe measures, including an adverse inference, dismissal, or default judgment, require a finding of intent to deprive another party of the information’s use in the litigation.
Replacing a phone is therefore not automatically sanctionable. The preservation duty, actual loss, recovery options, and relevant conduct matter. State-law standards and violations of specific court orders may require a different analysis.
When to Contact a Lawyer
Contact your existing lawyer before changing phones during a lawsuit, especially when the device contains disputed communications or is covered by a preservation notice or court order.
If you have not hired counsel, explain the dispute and any urgent repair or return deadline. Our guide to documents to bring to a lawyer consultation can help you organize the background information.
Ask for a clear plan identifying what to preserve, who will collect it, whether the old device should remain available, and when any preservation restrictions can end.
