What are your cohabiting rights with a child?

Cohabiting couples do not enjoy the same automatic rights as their married counterparts, especially in relation to property and finances. For instance, if one partner owns the property solely, the other partner does not have an inherent right to it, unlike in a marriage.


This lack of automatic entitlement can raise complications, particularly upon the breakdown of the relationship.

However, when children are involved, the law offers some level of protection.

Both parents, regardless of their marital status, may be equally obliged to provide financial support for their children. The court holds the power to intervene for the child's benefit, often enabling one parent (usually the one with primary care of the child) to remain in the home until the child reaches a certain age.

Cohabiting applies when a couple who are not married or in a civil partnership, are living together.

Unmarried couples and parental responsibility

Parental responsibility in UK law is defined under section 3(1) of the Children Act 1989. It encompasses all the rights, duties, powers, responsibilities, and authority that a parent has in relation to the child and the child's property.

This includes making decisions about the child's education, medical treatment, religion, and where the child lives.

Unmarried mothers automatically have parental responsibility for their children from birth.

For unmarried fathers, the situation is slightly different. They can acquire parental responsibility in several ways. If the father is named on the birth certificate (after a certain date), he will have parental responsibility.

Additionally, an unmarried father can acquire parental responsibility by entering into a parental responsibility agreement with the mother or by obtaining a parental responsibility order from the court.

An unmarried father would also gain parental responsibility if he marries the mother of the child.

The law is designed to protect the best interests of the child, and the acquisition of parental responsibility by an unmarried father allows him to be involved in important decisions regarding the child’s upbringing.

It's important to note that parental responsibility does not depend on the payment of child maintenance or the amount of contact time a father has with his child; it's focused on the child’s welfare and the ability to make key decisions in their life.

Rights of unmarried couples with children

In the context of unmarried couples with children, the mother automatically gains parental responsibility from the moment of the child's birth. However, for unmarried fathers, acquiring parental responsibility can be achieved under specific conditions.

These include being named on the child's birth certificate (for births registered after 1st December 2003), entering into a parental responsibility agreement with the mother, obtaining a parental responsibility order from the court, or by marrying the mother of the child.

It's important to note that parental responsibility does not depend on the payment of child maintenance or the amount of contact time a father has with his child; it focuses on the child’s welfare and the ability to make key decisions in their life.

Cohabitation agreements and their importance

A cohabitation agreement is a legal document designed to protect the rights of a cohabiting couple. Unlike marriages and civil partnerships, there's no specific legislation in England and Wales for such agreements, yet they are recognised under UK family law as an important tool for supporting couples who choose to live together without marrying.

These agreements typically include provisions related to property ownership, financial provisions, and, where applicable, child access.

For instance, they can regulate interests in property, bank accounts, and payment of household bills.

In terms of children, both married and unmarried parents have a legal obligation to provide child support, and a cohabitation agreement can detail the financial assistance each parent will provide.

This is particularly important for cohabiting parents, as it ensures that both parties understand their responsibilities and the legal implications thereof.

In many cases, cohabitation agreements can prevent future claims against the other parent if the relationship breaks down. This kind of legal protection is especially valuable in avoiding costly property disputes or issues around child support, given that unmarried couples rights are not as clearly defined as those of married couples.

Moreover, in contrast to the misconception of 'common law marriage', cohabitation agreements offer more certainty and legal clarity for cohabiting relationships.

While unmarried mothers automatically have parental responsibility, unmarried fathers can acquire it under limited circumstances, which can be outlined in a cohabitation agreement.

The agreement ensures two parents should feel equally responsible towards their child, regardless of their marital status.

It's worth noting that a non-resident parent may still be required to pay child support, even in situations where they have minimal contact with the child. Cohabitation agreements are thus a critical part of ensuring financial provision and maintaining the rights of all parties involved in a cohabiting relationship.
