Taking Your Child on Holiday After Separation: The Rules and the Paperwork

Most separated parents find out about this rule at the airport. A grandparent is asked for a letter, a border officer asks who the father is, somebody says the word "abduction" out loud, and the holiday stops feeling like a holiday.

This guide covers what the law actually requires, what to carry so nobody has to ask, and the part that is usually missing from solicitor pages: how to ask for consent, and how to make it easy to say yes.

The rule, in plain English

• Everyone with parental responsibility (PR) must consent before a child leaves the UK. Taking a child abroad without that consent can amount to child abduction under the Child Abduction Act 1984.
• PR does not disappear when you separate. Mothers have it automatically. Fathers usually have it if they were married to the mother or named on the birth certificate. It survives divorce and separation.
• The 28-day exception. If a child arrangement order says the child lives with you, you can normally take them abroad for up to 28 days without the other parent's permission — unless your order says otherwise, or there is a prohibited steps order in place.
• Consent does not have to be written to be valid — but written consent is what you will be asked for at a border, so treat it as the standard.
• If consent is refused, the route is mediation first and then a Specific Issue Order from the family court.

A UK holiday is a different thing

The permission requirement kicks in when the child leaves England and Wales. A week in Cornwall, a weekend in the Peak District or a trip to Scotland is not caught by it. What that does not mean is that you can rearrange someone else's time for a domestic trip — if your holiday eats into your ex's weekend, you still need their agreement, and asking in advance is the whole difference between a favour and a fight.

What to carry: the border file

Most airport problems are paperwork problems, and they are all avoidable. Keep these together in one folder, with photos of the lot on your phone:

• A signed, dated consent letter from every person with parental responsibility — ideally witnessed, ideally the original.
• The child's birth certificate (or adoption certificate) showing your relationship to them.
• The trip details: flight numbers, dates, accommodation address, return date.
• Proof of your own name history if your surname differs from your child's: a marriage certificate, a divorce certificate, or a name change deed.
• Any relevant court order, if one exists.

Some countries are stricter than the UK about children travelling with one parent, and a few ask for consent to be notarised or accompanied by a formal entry document. Check the destination's own requirements before you book — not the week before you fly.

The consent letter, and how to write it

A consent letter only needs to do one job: prove to a stranger at a desk that the other parent knew about this trip and agreed to it. It should include:

• Full names of both parents, and of every person with PR giving consent.
• The child's full name, date of birth and passport number if you have it.
• The exact travel dates, the destination and the accommodation address.
• Flight numbers, and who is travelling with the child.
• The consenting parent's phone number and address.
• A clear sentence giving consent, a signature and a date.

Here is a version you can copy and adapt:

CONSENT TO TRAVEL ABROAD

I, [full name], of [address], am the [mother / father / person with
parental responsibility] of [child's full name], born [date of birth],
passport number [number].

I give my consent for [child's name] to travel to [country and town]
with [name of travelling parent or adult] from [departure date] to
[return date], travelling on flight [numbers] and staying at
[accommodation name and address].

I understand that [travelling adult] will return [child's name] to the
UK on [return date] and that I can be contacted at any time on
[phone number] or by email at [email address].

Signed: ..................................
Full name: ...............................
Date: ....................................
Witnessed by: ............................
Witness signature and date: ..............

One tip worth more than the rest: take a photograph of the signed letter and keep it in a photo album on your phone that you can open without a signal.

How to ask so that the answer is yes

Consent requests go wrong for a predictable reason: they are too vague. "Can I take her to Portugal in August?" hands your ex a yes-or-no decision with no information attached, and human beings say no to those.

Send one complete proposal instead, with six things in it:

1. The dates — departure and return, not "summer".
2. Where and when — town, accommodation, flight numbers if you have them.
3. Who is going — including any new partner, and how they relate to your child.
4. How the child keeps in touch — a call every evening, a photo a day, whatever is realistic. Commit to it and then do it.
5. The make-up time — your offer to give back any of their time the trip takes (see below).
6. A deadline — "a reply by the 14th would let me book". Pressure with a date attached reads as organisation; pressure without one reads as an ambush.

And if you are the one being asked: reply, even if the reply is "I need to think until Friday". Silence is what turns a request into an application to court, and it is almost always read as a refusal.

The make-up time rule

If your holiday overlaps your ex's time with the children, offer the equivalent back — before or after, their choice. It is the single most effective thing you can do to get a yes, because it answers the fear underneath the refusal, which is usually not about the holiday at all but about losing time.

Then do the boring bit: put the swap in the shared calendar the moment it is agreed, so it is not renegotiated in September from memory. A shared calendar with a dated record of when the change was agreed settles most of this on its own, and it is the same habit that makes an organised record possible later if you ever need one.

If consent is refused

First, mediation. A surprising number of refusals shrink once the request is made properly and in writing, with a make-up time offer attached. Mediation is quicker, cheaper and far less damaging than an application — our MIAM and mediation guide explains how it works and what it costs.

Then, a Specific Issue Order. This is asking the family court to decide a particular point — here, whether the child can travel. Two things to know before you go down this road:

• The timeline runs in weeks to months. Do not book non-refundable travel hoping a court will rescue it. This is the mistake that costs people real money.
• The test is the child's welfare, and courts look hard at the risk of a child not being returned — especially where the destination is a parent's home country or where there is family abroad. A parent with a job, a home and family in the UK is in a very different position to one who does not.

If you are the one being asked to consent

Refusing is your right, and where there is a genuine welfare concern — a real risk the child will not be brought back, an existing order being undermined, a safety issue — refusing is the right thing to do. What does not age well is a refusal with no reason behind it, or one used as leverage in a different argument. Courts look at whether a refusal was reasonable, and "I did not want them to go" is not a reason that holds up well.

On passports, one point that comes up constantly: withholding a child's passport is not the same thing as refusing consent, and it is not a clean way to stop travel. If it blocks a trip that would otherwise be permitted, a court can be asked to order the passport's release. If you are refusing, refuse properly and say why.

Passports and paperwork, before you book

HM Passport Office requires the consent of everyone with parental responsibility for all child passport applications, including renewals, unless there is a court order dealing with it. So if there is any doubt about where you both stand, sort the passport before you plan the trip rather than after — a passport that takes eight weeks to issue has ruined more holidays than a disputed consent letter ever has.

Keep it all in one place

When a holiday goes smoothly nobody thinks about the paperwork again. When it does not, you will want three things: the signed consent letter, the message where the dates were agreed, and the record of the make-up time you offered and whether it happened. Keep them together, dated, and out of your camera roll. That is the same habit our guide to documenting co-parenting for court describes — not building a case, just being able to answer a question clearly six months later.

And if you are planning the wider year at the same time, the free custody schedule builder will show how a holiday and a make-up weekend fit around your existing pattern, which is far easier than trying to work it out in messages.
