Step-Parent Adoption in Wales: Process, Requirements, and Legal Considerations

Step-parent adoption in Wales is legally straightforward compared to adopting through the care system, but it carries permanent consequences that are worth thinking through carefully before applying. Making a step-parent the legal parent of a child also permanently removes the other birth parent's legal status — and that decision cannot be undone.

Who Can Apply for Step-Parent Adoption in Wales?

A step-parent can apply to adopt their partner's child in Wales if:

• They are married to or in a civil partnership with the child's legal parent, or are an unmarried partner who has lived with the parent for at least six months preceding the adoption application
• They are aged 21 or over
• The child is under 18 and is not and has not been married or in a civil partnership

The biological parent who is also the adopting step-parent's partner does not lose their parental responsibility — they remain a legal parent. What changes is that the child gains a second legal parent (the step-parent) and the other birth parent's legal status is extinguished, unless consent orders or specific arrangements are made for ongoing contact.

The Role of the Other Birth Parent

This is often the most complex aspect of step-parent adoption in Wales. There are two scenarios:

If the other birth parent consents: The adoption can proceed with their written consent. This is filed with the court. Consent can be withdrawn before the final hearing but not after the adoption order is made.

If the other birth parent does not consent — or cannot be found: The court can dispense with consent on limited grounds, most commonly that the welfare of the child requires the adoption order regardless. Courts are cautious about dispensing with parental consent — it is a significant legal step. If the other birth parent has maintained meaningful contact and wishes to remain in the child's life, an adoption application is unlikely to succeed.

If the other birth parent has had no contact with the child for several years and cannot be located, the court may agree to dispense with consent, but the procedure requires formal attempts to serve notice on that person, which can be time-consuming.

The Court Process in Wales

Step-parent adoption is handled by the Family Court in Wales. The process runs as follows:

1. Application — filed using Form A58, the standard adoption application. The application must be supported by the required documentation, including birth certificates, marriage certificate (if applicable), and statements from both the applicant and the parent who is their partner.

2. Children and Family Court Advisory and Support Service (CAFCASS) Cymru — once the application is filed, CAFCASS Cymru is appointed to represent the child's interests. A CAFCASS officer (a Guardian) will be appointed to assess whether the adoption is in the child's best interests, interview the child (depending on age), and report to the court.

3. Court hearing — the judge considers the CAFCASS report, any consent filed, and evidence from the applicants. If everything is in order and consent is confirmed, the hearing can be straightforward.

4. Adoption order — if granted, the step-parent becomes the child's legal parent. A new birth certificate is issued naming both the biological parent and the step-parent as the child's parents.

The timeline for step-parent adoption in Wales is typically 6–12 months from application to order, depending on court availability and whether consent is uncontested.

Is a Full Adoption Order the Right Choice?

Before applying for a step-parent adoption order, it is worth considering whether it is the right legal mechanism or whether other options better serve the child's interests.

Parental Responsibility Agreement or Order — if the goal is for the step-parent to have legal authority to make decisions about the child's upbringing (consent to medical treatment, school decisions), a Parental Responsibility Agreement or court-ordered PR is a less permanent and less legally significant step. It does not remove the other birth parent's status.

Adoption is appropriate when:

• The other birth parent has genuinely played no role in the child's life for many years
• The child identifies fully with their step-parent as their "real" parent and wants the legal confirmation
• There is no ongoing relationship between the child and the other birth parent that an adoption order would sever
• The child is old enough to understand what adoption means and expresses a clear preference

Adoption may not be appropriate when:

• The child has an ongoing relationship with the other birth parent, however imperfect
• The motivation is primarily practical (surname change, inheritance, or passport) rather than about the child's identity and wellbeing
• The child has mixed feelings about losing the other birth parent's legal status

CAFCASS Cymru will assess the child's wishes and feelings as part of their report. For children over about 12, their views carry significant weight in Welsh family courts.

The Child's Identity and Consent

Wales was the first UK nation to embed the UNCRC into domestic law. Under the Rights of Children and Young Persons (Wales) Measure 2011, courts must give due regard to the child's right to identity (Article 8 UNCRC) and their right to be heard (Article 12 UNCRC). In step-parent adoption cases, this means:

• Children over 12 (and sometimes younger, depending on maturity) are typically interviewed by CAFCASS Cymru about their views
• A child's strong objection to adoption will be given serious weight by the court
• If the child has an existing relationship with the other birth parent, this is a significant factor

No Assessment by NAS Wales

Unlike adoption through the care system, step-parent adoption does not go through NAS Wales's two-stage assessment process. There is no social work assessment by the regional collaborative, no Adoption Panel, and no approval process. The application goes directly to the family court, and the CAFCASS Cymru report is the primary independent assessment.

This makes the process faster, but it does not make the legal consequences any less permanent. Once an adoption order is granted, it cannot be revoked. The step-parent is the child's legal parent for life.

Getting Legal Advice

Given the permanence of the decision and the complexity of dispensing with consent where required, most families pursuing step-parent adoption in Wales benefit from legal advice before filing the application. A family solicitor with experience in Welsh adoption law can advise on whether the case is straightforward, how to handle a non-consenting or absent other parent, and how to structure the application most effectively.

Legal aid is generally not available for adoption applications, but some solicitors offer fixed-fee services for uncontested step-parent adoptions.
