The Family Court routinely receives digital evidence in fact-finding, private law and public law proceedings. It is a permissive forum in the sense that hearsay is admissible under section 4 of the Children Act 1989 hearsay provisions and equivalent private-law rules, but it is not a permissive forum on authenticity. When a party contests a screenshot — as opposing parties routinely do — the court needs a way to be satisfied that the exhibit is what it purports to be. A screenshot does not provide that. A properly acquired extraction, reported to FPR Part 25 standard, does.
Why screenshots fail
- Sender attribution can be edited on the device using freely available tools before the screenshot is taken.
- Timestamps in the visible UI do not carry the internal message-database rowid or server timestamp that would corroborate them.
- The thread as displayed can be cropped, filtered by 'starred' messages, or reordered before capture.
- Deleted messages in the middle of a conversation do not appear, so the exhibit is incomplete without the reader knowing so.
- The screenshot itself carries no cryptographic tie to the device it was taken on — one phone can produce a screenshot that appears to be from another.
What the Family Court is prepared to rely on
| Evidence type | What it establishes | Standard |
|---|---|---|
| Forensic extraction of the handset | Message content with sender attribution, timestamps, message IDs, and deleted-content indicators. | Reproducible, hashed, chain-of-custody documented. |
| Two-sided reconciliation | Both ends of a conversation, agreeing at the database-identifier level. | Materially strengthens the weight of the extract. |
| Cloud-backup acquisition | Content held in iCloud or Google account, including material no longer on the device. | Requires the account credentials or a court order. |
| Short FPR Part 25 report | Plain-English explanation of what was extracted, how, and its limits. | Signed by a named examiner with duty-to-the-court declaration. |
What to advise the client on day one
- 01Do not delete anything. Not the message, not the thread, not the app. Deletion after proceedings are contemplated can itself be a finding against the party.
- 02Do not export the chat to text and rely on the export. The exported .txt is not the evidence — it is a derivative that cannot be authenticated against the source.
- 03Preserve the handset in the state it is in. Turn off auto-delete on WhatsApp and iMessage, disable disappearing-messages settings, keep the phone charged and to hand.
- 04Get the phone to an examiner. A same-day acquisition preserves the state; analysis and report can follow.
- 05Where the other party's device is relevant, seek disclosure early. Two-sided reconciliation is much more persuasive than one-sided extraction.
The exhibit that started life as a screenshot and ends up as a forensic extract does not just gain evidential weight — it transforms the credibility of the party producing it. That transformation happens on the day the phone is preserved, not the day it is served.
Where phone evidence is decisive
- Fact-finding on allegations of domestic abuse, including patterns of coercive and controlling behaviour visible in the message record.
- Contact and residence disputes where the parties' communications are the primary contemporaneous account.
- Non-molestation and occupation orders where the pattern of contact is contested.
- Public law proceedings where safeguarding assessments turn on the parent's stated conduct against the electronic record.
What to instruct
A Part 25-compliant instruction identifies the device, the account or accounts in scope, the date range, and the specific issues the report should address. It should ask for a plain-English explanation of what was extracted and how, a note of what was not reachable and why, and — where the report will be read by a lay judge or lay parties — a short glossary. The report is short by design; the working papers, the hash log and the image sit behind it in case the examination is challenged.
Frequently asked questions
Only where the exhibit is uncontested. As soon as the other party denies it or challenges the sequence, the screenshot ceases to answer the question, and the extraction is what is needed.
By consent, or by court order. The Family Court has directed forensic examination of a party's device where the material is central and the party has been unable to disprove the allegation without it.
Where proceedings are contemplated, the party must disable disappearing-message features on relevant threads. Failing to do so is a preservation failure and, in our experience, is treated as such by the court.
Materially less than clients expect. A single-device instruction, scoped to a specific date range and set of issues, is a routine and proportionate step in a fact-finding matter.
The court can direct preservation and disclosure of a device, and can direct the involvement of an independent examiner where an issue of authenticity has been raised. Practice varies by circuit but the direction is far from unusual.
