# Parental responsibility: who has it and how it's acquired

> **Key takeaway:** Mothers: automatic. Married/civil-partnered fathers: automatic. Unmarried fathers: registration, agreement, or court order (s.4). Step-parents: agreement or court order (s.4A). Multiple holders can coexist; each can act alone unless a court says otherwise.

## What is this about?

Parental responsibility (PR) is the legal bundle of rights, duties, and authority a parent holds in relation to a child. Not every parent has it automatically, and more than one person can hold it at the same time — this entry sets out who has it, and the routes by which it can be acquired.

## What is the core rule?

Children Act 1989 s.3 defines parental responsibility as all the rights, duties, powers, responsibilities and authority a parent has by law in relation to a child and their property. Under s.2, a mother automatically has PR; a father automatically has it only if married to, or a civil partner of, the mother at the time of the child's birth. An unmarried father can acquire PR under s.4 by being registered as the child's father on the birth certificate, by agreement with the mother, or by court order. A step-parent can acquire PR under s.4A, inserted by the Adoption and Children Act 2002, by agreement with those who already hold it or by court order.

## What are the elements or test?

1. Mother: automatic PR in all cases (s.2)
2. Father married to/civil partner of the mother at birth: automatic PR (s.2)
3. Unmarried father: PR via (a) registration as father on the birth certificate, (b) agreement with the mother, or (c) court order (s.4)
4. Step-parent: PR via agreement with existing PR-holders or court order (s.4A)
5. Multiple people can hold PR simultaneously (s.2(5)); each may act alone in exercising it (s.2(7)) unless a court order provides otherwise

## Which authorities matter?

- **Children Act 1989, s.2** — Sets automatic acquisition of PR for mothers and, where married/civil partnered at birth, fathers.
- **Children Act 1989, s.3** — Defines parental responsibility.
- **Children Act 1989, s.4** — Sets the three routes by which an unmarried father can acquire PR.
- **Children Act 1989, s.4A (inserted by Adoption and Children Act 2002, s.111)** — Allows a step-parent to acquire PR by agreement or court order, as an alternative to adoption.

## How does this apply in practice?

PR is a status question, separate from questions of contact, residence, or day-to-day care — someone can hold PR without living with the child, and someone can care for a child day-to-day without holding it. Once acquired by an unmarried father or step-parent, PR can only be brought to an end by court order, not simply withdrawn by agreement.

## What are common pitfalls?

- Assuming an unmarried father automatically has PR in the same way a married father does — he does not, without taking one of the s.4 routes
- Treating PR as equivalent to having contact with, or custody of, a child — they are legally distinct concepts
- Overlooking that once acquired, PR can only be ended by court order, not informally

## When would a practitioner use this?

Relevant when establishing who has legal authority to make decisions about a child's upbringing, medical treatment, education, or relocation, and when advising on how an unmarried father or step-parent can formalise their legal status.

## Quick reference

Mothers: automatic. Married/civil-partnered fathers: automatic. Unmarried fathers: registration, agreement, or court order (s.4). Step-parents: agreement or court order (s.4A). Multiple holders can coexist; each can act alone unless a court says otherwise.
