How Does Paternity Leave Work?

Last updated 12 November 2026 · Paternity Leave Calculator editorial team

Paternity leave is time off work for a father or partner when a baby is born or adopted. The details depend almost entirely on where you work, so it helps to understand the building blocks before looking at your own country's rules.

The three layers of paternity leave

Most arrangements combine up to three layers: a statutory (legal) right to time off, a statutory payment during that time, and anything extra your employer offers in your contract or policy.

These layers are separate. You can have a right to leave without a right to pay — the US federal FMLA works like this — or an employer can pay more than the legal minimum.

Eligibility usually depends on employment

Statutory schemes commonly require you to be an employee (not self-employed) and to have worked for your employer for a minimum period. In the UK, for example, Statutory Paternity Leave requires 26 weeks of continuous employment by the end of the 15th week before the due week.

Some countries pay benefits through social insurance instead, where eligibility depends on contributions or insured hours rather than your specific employer.

Timing and notice

Rules typically set a window in which leave must be taken (often linked to the birth date) and a deadline for telling your employer. Missing a notice deadline can delay or reduce your leave, so check this early.
