Serving documents in family proceedings — proof, timing and the rules

REVIEWED BY: Sean McNamara on 2026-08-31

What 'service' means

Service is the formal process of delivering court documents to the other party (and the court). Getting it right matters — a document "served" incorrectly can mean a hearing adjourns or an order is challenged.

Who must be served

The respondent / other party — every document you file with the court
The court — copies of everything you send to the other side
Other parties joined to the case (e.g. grandparents, a local authority)

How to serve

| Method | When it's used | Proof | |--------|---------------|-------| | Email | If the other party has agreed to email (or uses a solicitor who does) | Delivery receipt / 'read' receipt | | First-class post | Standard method | Keep the proof of posting (certificate of service) | | Personal delivery | Where post is risky or the court directs it | Signed acknowledgment | | Through a solicitor | If the other side has one | The solicitor's acknowledgment |

Deemed service — the 'deemed date'

Under the Family Procedure Rules, service by first-class post is deemed effective on the 2nd business day after posting; email is deemed effective on the day sent (if before 4:30pm). This 'deemed date' is what deadlines run from — not the day the other party actually reads it.

If the respondent can't be found

You can apply to the court for dispensation with service — the court can order that service is deemed done even though you couldn't deliver it, if you've tried reasonable steps
Alternative service — the court can order service by a method that's likely to reach them (e.g. a specific email, posting to a known relative, or social media message)
Keep evidence of your attempts (returned post, phone records, email bounces)

Certificate of service

File a certificate (often on the form the court specifies) confirming the document was served and how
Attach evidence: proof of posting, email delivery receipt, acknowledgment

Common mistakes

Serving by a method the court didn't authorise
Missing the deadline (deemed date matters more than the postmark)
Not serving the court copy at the same time
Serving onto the wrong person (e.g. the other party's new partner instead of them)
Losing the proof of service — you'll need it if service is disputed

Safety note for abuse cases

If your address is sensitive (you hold a non-molestation order), use the court's confidential address procedure — your address is kept off the documents the other side sees. See our FL401 and safety guides.
