Part of: How to Adopt a Child and Change a Life

Same-sex adoption means a couple of the same sex, or a single lesbian, gay, bisexual or trans person, adopting a child. In England and Wales a same-sex couple has exactly the same right to apply as any other couple. Married, civil partners or living together, the rule is the same (Adoption and Children Act 2002, s.144(4)). Your sexuality is not a test you have to pass.

What changes from family to family is the legal route. A child placed by an agency, your partner’s child, a baby born through surrogacy and a baby born after donor treatment each follow different law, with different time limits. This guide sets out each route. It sits within our guide to how to adopt a child and change a life.

Key takeaways

  • A couple who can adopt includes two people of the same sex living as partners in an enduring family relationship. You do not need to marry first (s.144(4)).
  • Couples apply together once both of you are 21. A single person aged 21 or over can adopt alone (ss.50 and 51).
  • To adopt your partner’s child, the child must have lived with you both for six months, and the council needs three months’ notice (GOV.UK).
  • After surrogacy the usual route is a parental order, applied for within six months of the birth. Adoption is the fallback (HFEA 2008, s.54).

Can same-sex couples adopt in England and Wales?

Yes. The Adoption and Children Act 2002 lets a couple apply to adopt together. A couple means a married couple, civil partners, or two people of different sexes or the same sex living as partners in an enduring family relationship.

You will find that definition in section 144(4), and section 49 lets a couple apply jointly. Both of you must be at least 21 (s.50(1)). At least one of you needs a domicile in the British Islands, or you both need a year of habitual residence here (s.49(2) and (3)).

According to GOV.UK, you may be able to adopt if you are single, married, in a civil partnership, an unmarried couple of either sex, or the partner of the child’s parent. There is no upper age limit, and you do not need to be a British citizen.

On 30 December 2005, when the joint application rules in the Adoption and Children Act 2002 came into force. Section 49 is the provision that lets a couple, of any sex, apply to adopt together.

You can check the commencement date against section 49 on legislation.gov.uk. Rules on same-sex adoption in the UK differ by nation, because Scotland and Northern Ireland have their own adoption laws. This guide covers England and Wales only.

How does same-sex adoption through an agency work?

LGBT+ adopters apply to an adoption agency, either the council’s or a voluntary agency, and go through the same assessment as everyone else. GOV.UK says approval normally takes around 6 months, followed by matching with a child.

  1. You contact an agency. It arranges to meet you and may invite you to a group meeting with other people hoping to adopt. Then it gives you an application form.
  2. You attend preparation classes, and a social worker visits you several times to assess whether you are suitable to adopt.
  3. The agency runs a police check, asks for three referees (one can be a relative) and arranges a full medical (GOV.UK).
  4. An independent adoption panel reads the assessment report and makes a recommendation. You can attend and answer its questions.
  5. The agency decides whether you can adopt, then begins looking for a child who fits your family.
  6. Once a child has lived with you for 10 weeks, you can apply to the family court for an adoption order (s.42(2)). The court fee is £212 (GOV.UK).

Expect questions about your relationship, your support network and how you would talk with a child about their story. For unmarried couples, the social worker will look at how long you have lived together and how settled you are. Children adopted from abroad also follow extra rules, set out in our guide to intercountry adoption.

Can an adoption agency turn you down for being gay, bisexual or trans?

No. An agency must not refuse you because of your sexual orientation or gender reassignment. Both are protected characteristics under the Equality Act 2010, and a service provider must not discriminate by refusing you or offering worse terms.

The Act defines them in section 12 (sexual orientation) and section 7 (gender reassignment), and sets the duty on service providers in section 29. An agency can still say no for reasons that have nothing to do with sexuality. You cannot adopt if you or an adult member of your family has been convicted of a serious offence, such as one against a child.

If an agency says no, GOV.UK explains that you can challenge the decision in writing or apply to the Independent Review Mechanism. You can also approach another agency, although you would start again.

Is same-sex adoption the right route for your family?

That depends on how the child came into your family. Adoption is one of four routes. For babies born through surrogacy or donor treatment it is often the wrong one.

The legal routes to parenthood for same-sex couples and LGBT+ adopters in England and Wales
Your situationThe routeTime rule to watch
A child placed by an adoption agencyJoint adoption as a couple (s.50), or adoption by one person (s.51(1))Child must live with you for 10 weeks before you apply (s.42(2))
Your partner’s childAdoption by the partner of a parent (s.51(2)); your partner stays a parentSix months living with you both, and notice to the council 3 months to 2 years before applying (ss.42(3) and 44(3))
A baby born through surrogacyParental order, if the egg or sperm of at least one of you was used (HFEA 2008, ss.54 and 54A)Apply within 6 months of the birth
A baby born to your female partner after donor treatmentOften no order is needed: you may already be a legal parent (HFEA 2008, ss.42 to 44)Consent forms must be signed before treatment if you are not married or civil partners

Can I adopt my partner’s child in a same-sex relationship?

Yes. A person aged 21 or over can adopt alone if the court is satisfied that they are the partner of the child’s parent, and your partner remains the child’s parent afterwards (s.51(2); s.67(3)(a)).

The child must have lived with you both for six months before you apply (s.42(3)). You must give your council notice of your intention to adopt at least three months, and no more than two years, before the application (s.44(3)). After that, the council investigates and reports to the court.

The order ends the other birth parent’s parental responsibility and cancels any existing order about when that parent sees the child (GOV.UK). For that reason, that parent’s consent normally matters. Also, statutory adoption leave and pay do not apply when you adopt a stepchild (GOV.UK).

Because adoption is permanent, a parental responsibility order or special guardianship can sometimes fit better. Our guide to step-parent adoption vs special guardianship compares them, and our guide to same-sex parents’ rights and parental responsibility covers the other options.

Your family is already real. The right order makes sure the law says so too.

Do you need to adopt after surrogacy or donor treatment?

Often you do not. After surrogacy the usual route is a parental order, and after donor treatment a female partner may already be the child’s legal parent from birth.

If you were married to the birth mother, or her civil partner, at the time of treatment, the law treats you as a parent unless you did not consent (HFEA 2008, s.42). If you were not, you become a parent only after treatment at a licensed UK clinic, with written consent notices you both signed beforehand (s.43 and s.44). Without that, adopting your partner’s child under s.51(2) may be the way to become a legal parent. Our guide to sperm donors and the law explains clinic and private donation.

After surrogacy, a couple can apply for a parental order if at least one of you is genetically related to the baby. You must apply within six months of the birth, the child must live with you, and the surrogate must agree freely and unconditionally (s.54). A single parent can apply under s.54A. However, if neither of you is genetically related to the baby, adoption becomes the route. Our guide to surrogacy laws in the UK sets out the steps.

How does the court decide a same-sex adoption application?

Exactly as it decides any other. The child’s welfare, throughout their life, is the paramount consideration, and your sexuality is not one of the factors on the checklist.

That checklist in section 1 of the 2002 Act includes the child’s wishes and feelings, their particular needs, the effect of leaving their birth family and their relationships with relatives. The court must also keep in mind that delay is likely to harm the child (s.1(3)). Before the judge makes an order, the agency or council must have seen the child with you at home often enough (s.42(7)).

Once the judge makes the order, the law treats the child as born to you, and as the child of your relationship (s.67(1) and (2)). Our guide to adoption orders explains what the order does and how long it takes.

We advised two women whose son was conceived at home with sperm from a friend. They were not married, so in law his parents were the mother who carried him and the friend. The friend appeared on no document. Her partner had done the night feeds and the nursery runs since the first week, yet she could not sign a consent form at the hospital. We talked through adopting him as the partner of a parent, which would keep his mother’s status intact, against a parental responsibility order. We also explained the notice the council would need and why the friend’s position had to be clear first. What happens in any case turns on its own facts.

Expert Tip

If you are not married or civil partners, gather the paperwork that shows you live as a family before the assessment starts: the tenancy or mortgage in both names, shared bills, and how long you have lived together. The law asks whether you are in an enduring family relationship (s.144(4)), and a social worker will want to see more than your word for it.

Same-sex adoption: frequently asked questions

Do we have to be married or in a civil partnership to adopt together?

No. Two people of the same sex living as partners in an enduring family relationship count as a couple who can adopt together (Adoption and Children Act 2002, s.144(4)). The assessment will look at how settled your relationship is.

Can a single gay man adopt a child?

Yes. Anyone aged 21 or over who is not married or in a civil partnership can apply to adopt alone (s.51(1)). The agency assesses you as it would any other single applicant.

Can trans people adopt in England and Wales?

Yes. The adoption rules do not exclude anyone because of gender identity, and gender reassignment is a protected characteristic under the Equality Act 2010, s.7. The agency looks at suitability in the same way for every applicant.

Do both of us get adoption leave?

No. Only one person in a couple can take statutory adoption leave, and the other partner may be able to take paternity leave instead (GOV.UK). You decide between you who takes which.

Planning to adopt together?

The costly mistakes in same-sex adoption come from choosing the wrong route. Couples assume a non-birth mother is a parent when nobody signed the consent forms. Others miss the six-month window for a parental order, or adopt a partner’s child without weighing what it ends for the other birth parent. Each one can leave a child without the legal parent they live with every day.
