Do Step-Parents Have Parental Responsibility? What the Law Actually Says
Blog last updated: November 2026 | Jurisdiction: England and Wales | Estimated reading time: 7 minutes (excluding FAQs)
Some people assume that once they marry, or form a civil partnership with, someone who has children, they take on the legal rights of a parent. As the law currently stands, they do not. A step-parent may be closely involved in a child’s everyday life and still not have parental responsibility, which is the legal authority to make decisions about that child. The gap tends to come to light at an awkward moment, such as when a school or a hospital asks who is able to give consent.
Step-parent parental responsibility: what the law says
In England and Wales, a step-parent is someone who is married to, or in a civil partnership with, a child’s parent but is not the child’s parent or adoptive parent themselves. Parental responsibility is the legal term for the rights, duties and authority a parent has in relation to a child, such as deciding where the child lives and which school they attend. A child’s birth mother has it automatically, and the child’s father or second parent may also have it, depending on the circumstances. As the law currently stands, a step-parent does not acquire it automatically simply by marrying, or entering a civil partnership with, a parent who has it.
Potential impacts of not having parental responsibility
Without parental responsibility, a step-parent may find that their ability to make decisions about the child is limited to day-to-day matters, and they may not be able to agree to medical treatment or sign school forms in the same way a parent can. In practice this often works because the biological parents remain responsible for the child and continue to make the bigger decisions in the child’s life whilst permitting the step-parent to help out. It may be less workable if the biological parents and the step-parent disagree about a decision such as medical treatment or schooling, if one of the biological parents is no longer in the child’s life and the step-parent has taken over their role in practice, or if the relationship ends, which is why some families decide to put the position on a formal footing.
There are several routes for a step-parent to obtain parental responsibility for the child:
- Parental Responsibility Agreement
- Parental Responsibility Order
- Child Arrangements Order
- Becoming the child’s legal guardian
Getting parental responsibility by agreement
The simplest route is usually a parental responsibility agreement. It is available only where the step-parent is married to, or in a civil partnership with, a parent who has parental responsibility. Every other person with parental responsibility for the child (usually the biological mother and father) and the step-parent sign the agreement. Step-parents use a specific form, known as Form C(PRA2), and GOV.UK explains how to apply for parental responsibility. The form is signed and witnessed at your local family court and then sent to be recorded to the Central Family Court in London. The agreement does not take effect until that has happened.
Because the agreement is formal and, once made, cannot simply be withdrawn, it is worth taking legal advice before anyone signs. If the other parent has parental responsibility and does not agree, this route is not available, and the step-parent may need to consider an application to the court instead.
Applying to court for a parental responsibility order
Where an agreement is not possible, a step-parent who is married to, or in a civil partnership with, a parent may apply to the court for a parental responsibility order, using Form C1. Before applying, the step-parent is generally expected to attend a mediation information and assessment meeting (a MIAM), unless an exemption applies, such as where there has been domestic abuse. The mediator and the step-parent will consider whether mediation or another form of non-court dispute resolution, such as collaborative law or arbitration, may be suitable and can be agreed with the child’s parents. The child’s welfare is the court’s paramount consideration, and it will weigh matters such as the child’s wishes and feelings and the likely effect on the child of making the order. It will also look at how committed the step-parent is to the child and why the application is being made.
How things might work in practice
Take a step-parent who has lived with a child and the child’s mother for six years and has taken on much of the school and medical organisation, while the child’s father lives abroad and takes little part. The mother is content for the step-parent to have parental responsibility, but the father will not sign. A court may be willing to make an order if it considers that doing so is better for the child than making no order, although the outcome would depend on the specific circumstances.
A parental responsibility order does not take anything away from the child’s parents. They keep their parental responsibility, and the step-parent shares it.
If you are not married to, or in a civil partnership with, the parent
The agreement and the order described above are available only to the spouse or civil partner of a parent. A partner who has not married or entered a civil partnership with the parent cannot use them. For an unmarried partner, the main route is a child arrangements order. Where the court makes an order that a child is to live with someone who does not have parental responsibility, the court is required to give that person parental responsibility for as long as the order provides for the child to live with them. Where an order provides only for the child to spend time with someone, the court may, but does not have to, give them parental responsibility as well.
Leave to apply
A person who is not a parent may need the court’s permission, known as leave, before applying for a child arrangements order, but there are exceptions. A spouse or civil partner of a parent can apply without leave where the child has been treated as a child of the family, and the law says this applies whether or not the marriage or civil partnership is still continuing. Anyone with whom the child has lived for at least three years can also apply without leave. We cover leave in our post on grandparents and their legal rights, and our child arrangements page explains the wider process.
What happens to a step-parent’s parental responsibility if the relationship ends or the parent dies?
Parental responsibility acquired by a step-parent, whether by agreement or by court order, does not end simply because the parent and step-parent separate or divorce. As the law currently stands, section 4A of the Children Act 1989 provides that it may be brought to an end only by a court order. That application may be made by anyone with parental responsibility for the child or, with the court’s permission, by the child themselves if they have sufficient understanding. Parental responsibility given through a child arrangements order is different, because it lasts only for as long as the order provides.
Child arrangements without leave
A step-parent who has parental responsibility under section 4A of the Children Act 1989 is also entitled to apply to the court for a child arrangements order without needing leave. Parental responsibility does not by itself guarantee a step-parent contact with the child after a separation, and arrangements may need to be agreed or decided separately. It is also a different question from whether a step-parent may be asked to contribute financially. On divorce or dissolution, the court may in some cases consider a financial claim in respect of a child who has been treated as a child of the family, which is a separate legal test and does not depend on whether the step-parent has parental responsibility. Our page on financial provision for children provides more information.
If the parent who has parental responsibility dies, a step-parent who has acquired it by agreement or by court order does not lose it for that reason, because it may be ended only by a court order. A step-parent without it does not automatically become the child’s guardian, which is covered below.
Becoming a legal guardian (which is different from adoption, not covered in this article)
A step-parent may also acquire parental responsibility by becoming a child’s legal guardian, although this route is more limited than it sounds and is rarely a practical alternative while the child’s parents are alive. A parent with parental responsibility may appoint a guardian in writing to act if they die, and a guardian acquires parental responsibility. If the child still has another parent with parental responsibility, the appointment may take effect only when there is no surviving parent with parental responsibility. A court may also appoint a guardian where the child has no parent with parental responsibility.
Becoming a special guardian
Special guardianship is a separate court order, which is more often used where a child cannot live with their parents. A special guardian has parental responsibility and may exercise it to the exclusion of others who have it, other than another special guardian, so the order can significantly affect the parents’ own role. A step-parent is not automatically entitled to apply and may need the court’s leave, unless, for example, the child has lived with them for at least three years or everyone with parental responsibility consents. The local authority must also report to the court before an order can be made. For a step-parent who simply wants to share parental responsibility with the child’s parents, an agreement or a parental responsibility order may be more suitable.
Getting advice on your situation
Whether a step-parent needs parental responsibility, and which route may suit, depends on the family’s circumstances, including whether the parents are married, and whether the other parent has parental responsibility and is likely to agree. It is worth taking advice before signing anything or making an application, so that you understand your options.

Frequently Asked Questions
Do step-parents have parental responsibility?
As the law currently stands in England and Wales, a step-parent does not automatically have parental responsibility, even if they are married to, or in a civil partnership with, the child’s parent. Parental responsibility is the legal authority to make decisions about a child’s upbringing, such as where they live and which school they attend, and gives them responsibility over that child to make medical decisions for them. A step-parent may acquire it by agreement with the child’s parents, by a court order or, in some cases, through a child arrangements order. Until then, a step-parent’s ability to make decisions about the child may be limited.
How does a step-parent get parental responsibility?
A step-parent who is married to, or in a civil partnership with, a parent may obtain parental responsibility by a signed agreement with the child’s parents, using Form C(PRA2), or by applying to the court for a parental responsibility order. A step-parent who has not married or entered a civil partnership with the parent cannot use either route, but a child arrangements order providing for the child to live with them gives them parental responsibility for as long as the order lasts. The right route may depend on whether the other parent has parental responsibility and whether they agree. It is worth taking advice before signing or applying.
Can a step-parent get parental responsibility without the other parent’s agreement?
A parental responsibility agreement needs the agreement of every parent who has parental responsibility, so it may not be available if the other parent refuses. A step-parent who is married to, or in a civil partnership with, a parent may instead apply to the court for a parental responsibility order, which may be made without the other parent’s consent depending on the circumstances. The court’s main concern is the child’s welfare, and it may consider matters such as the step-parent’s commitment to the child. Before applying, the step-parent is generally expected to attend a mediation information and assessment meeting unless an exemption applies.
Does a step-parent’s parental responsibility end on divorce?
Not automatically. Where a step-parent has acquired parental responsibility by agreement or by a court order, it continues after a separation or divorce unless and until a court brings it to an end. An application to end it may be made by anyone with parental responsibility for the child, or by the child themselves with the court’s permission. Parental responsibility given through a child arrangements order lasts only for as long as the order provides.
What happens to a step-parent’s parental responsibility if the parent dies?
A step-parent who has acquired parental responsibility by agreement or by a court order does not lose it simply because the parent dies, as the law currently provides that it may be ended only by a court order. A step-parent without parental responsibility does not automatically become the child’s guardian. A parent who has parental responsibility may appoint a guardian in writing, and this may include a step-parent. Where another parent with parental responsibility survives, the appointment may take effect only when there is no surviving parent with parental responsibility.
