Is paternity leave a day-one right, and can I split the two weeks?

Two weeks, splittable into two single weeks, usable at any point in the child's first year, and available from your first day in the job in Great Britain since April 2026. The notice rules, and why Northern Ireland has none of this.

Short answer

In England, Wales and Scotland, paternity leave became a day-one right on 6 April 2026 — no minimum service. You get two weeks, as one block or two separate single weeks, taken at any point within 52 weeks of the birth. Paternity pay is separate and still needs 26 weeks' service by the qualifying week plus earnings at or above the lower earnings limit. Give 28 days' notice of each period of leave.

This right has changed twice in quick succession and a great deal of advice online is out of date. Two things moved. From April 2024 the two weeks could be split and taken any time in the child's first year, instead of having to be two consecutive weeks within eight weeks of the birth. From April 2026 the leave itself became available from the first day of employment. The pay conditions were not changed by either reform, so it is entirely possible to be entitled to the leave and not to the pay.

Step by step

Confirm your relationship qualifies.You must be the child's biological father, or the spouse, civil partner or partner of the mother or of the primary adopter, and expect to have responsibility for the child's upbringing. It is not limited by gender.
Check the leave test — in Great Britain it is now day one.For births and placements from 6 April 2026 in England, Wales and Scotland, there is no qualifying service period for paternity leave. You must be an employee; workers and the self-employed do not qualify.
Check the pay test separately.Statutory Paternity Pay still requires 26 weeks' continuous employment by the qualifying week — the 15th week before the baby is due — and average weekly earnings at or above the lower earnings limit. The current rate is on the GOV.UK rates and thresholds page.
Decide how to split the two weeks.One block of two weeks, or two separate blocks of one week each. You cannot take odd days. Splitting suits families who want cover at the birth and again when a partner's leave ends.
Use the full 52-week window.The leave must end within 52 weeks of the birth, or of the child's placement or entry to the UK for adoption. Taking one week at the birth and one week months later is now normal and permitted.
Give the notices in time.Tell your employer the due date around 15 weeks before it. Then give at least 28 days' notice of each period of leave, and 28 days' notice if you want to change a date. For adoption the first notice is within seven days of being matched.
Know that you can now combine it with shared parental leave.The old bar on taking paternity leave after shared parental leave was removed in April 2026 in Great Britain. The two can be taken in any order.
Check whether your employer enhances it.Many employers pay full salary for some or all of the two weeks, and some offer far more. It is a contractual matter and worth asking about before the birth rather than after.
Northern Ireland: check nidirect, not GOV.UK.Northern Ireland has not adopted the 2024 or 2026 changes. The Northern Ireland position remains 26 weeks' service, two consecutive weeks only, and a much shorter window after the birth. Do not plan a split week on the strength of a GB page.

Tips

Give the 28-day notice for both weeks at once if you already know when you want them. It is easier than renegotiating later.
Ask whether your employer's enhanced paternity pay depends on taking the leave in one block. Some policies do.
Unpaid parental leave is the usual way to stretch two weeks into more. Its notice period is 21 days and the employer cannot refuse, only postpone.

Common mistakes

Assuming leave and pay follow the same test — Since April 2026 in Great Britain the leave is day one and the pay still needs 26 weeks' service. Plenty of new starters have the time off and not the money.
Reading a Northern Ireland question off a GOV.UK page — Northern Ireland has not made the 2024 or 2026 changes, so split weeks and day-one entitlement do not apply there.

If it doesn't work

Your employer says you have not been there long enough

Cause: They are applying the old service rule, or the pay rule to the leave — Fix: In England, Wales and Scotland the leave is a day-one right from 6 April 2026. Put it in writing, and contact Acas if it is not accepted. The pay may genuinely not be due, which is a separate answer.

The baby arrived early and your notice is now wrong

Cause: The 28-day notice was tied to a date that has moved — Fix: Tell your employer as soon as you can. The rules recognise that birth dates move and leave can start on the day of birth or the day after; get the revised dates confirmed in writing.

You want the second week months later and payroll says no

Cause: Payroll working from pre-2024 rules — Fix: Two separate one-week blocks within 52 weeks of the birth are permitted in Great Britain. Point them to the GOV.UK paternity page. In Northern Ireland they may be right.

Questions people ask

Can I take paternity leave if I have just started the job?

In England, Wales and Scotland, yes — the leave is a day-one right for births and adoption placements from 6 April 2026. You may still not qualify for paternity pay, which needs 26 weeks' service.

Do I need to prove the birth?

No. Statutory paternity leave and pay are claimed on a self-declaration; there is no requirement to produce a birth certificate. Employers may ask you to complete their own form or the online declaration.

Can I take unpaid parental leave as well?

Yes. Unpaid parental leave is an entirely separate entitlement of 18 weeks per child, and in Great Britain its one-year service qualification was removed in April 2026. It is commonly used to extend time off around a birth.

What if my partner dies?

A separate right introduced in April 2026 in Great Britain gives a bereaved partner up to 52 weeks of leave where the mother or primary adopter dies within the child's first year. It is unpaid and is a day-one right. Speak to your employer and to Acas immediately.
