Serving documents properly — service, deemed service and proof of delivery

REVIEWED BY: Sean McNamara on 2026-08-30

Filing a document with the court is only half the job — the rules also require you to serve it on the other parties. Get service wrong and a hearing can be adjourned or an order unenforceable. This guide covers the methods, the "deemed service" dates, and how to prove you served. It is general information, not legal advice.

Filing vs serving

Filing = sending the document to the court
Serving = delivering it to the other parties (and anyone else the order or rules require)
Most directions orders require both; a document filed but not served hasn't complied with the direction

Permitted methods of service

Under the Family Procedure Rules (Part 6), you may serve by any of these:

Personal service — handing it to the person (rarely needed; often via a process server)
First-class post to their address
Document exchange (DX)
Fax or email — if the recipient has indicated willingness to accept service that way (their solicitor's letterhead typically supplies an email address — that counts as indicating willingness), or there's a valid address for service
Other method the court permits

For a represented party, serve their solicitor. For an unrepresented party, serve them personally at their usual or last-known address.

Deemed service — when service legally counts

Service isn't complete the instant you press send. The rules deem service to happen:

| Method | Deemed served | |---|---| | First-class post | The second business day after posting | | DX | The second business day after leaving with DX | | Email / fax | After 12:00 midnight on the day sent — so it "counts" the next business day |

If a deadline requires the other side to have a document by a certain day, work backwards from the deemed date — an email at 9pm the night before may still technically miss a "serve by" deadline that requires receipt.

Serving special documents

Some documents have their own service rules:

Court orders: served with the required notices; if the order has a penal notice (warning that breach may be contempt), proper service matters enormously — you cannot enforce a non-molestation order for contempt without proof the respondent knew of it
Non-molestation / occupation orders: the court serves them, but keep your own evidence too; for enforcement you may need to show service
Financial remedy Form E: exchanged through solicitors or directly — dates matter because the whole timetable runs from exchange
Documents for a party in prison or abroad: special routes apply (prison mailrooms; Hague service for some overseas recipients) — get advice

Proving service — the evidence habit

1. Email: keep the sent email, with attachments, timestamped; request a read receipt (not conclusive, but useful); screenshot the delivery confirmation 2. Post: use Certificate of Posting (free at any Post Office counter) or Recorded/Special Delivery — keep the receipt and tracking 3. Process server: they provide a sworn certificate of service — the gold standard, worth the fee (~£80–£150) for critical documents 4. Statement of service: file a short document with the court — "I served [document] on [party] by [method] on [date]; deemed served [date]; evidence attached" — for every important document 5. Keep everything in your filing log (see our document organisation guide)

When service fails

You didn't serve in time: apply to the court immediately for retrospective validation or an extension — courts can dispense with service irregularities where no injustice was caused; honesty and speed are everything
The other side says they didn't receive it: deemed service protects you if you used a permitted method — your certificate of posting or sent email is your defence
They're evading service: the court can authorise alternative service (email to a different address, service on a family member, social media in extreme cases) — apply with evidence of the evasion
