When a baby is born through international surrogacy, one of the most important post-birth questions is: what citizenship does the baby have, and which passport can the baby use to travel?
The answer is not always determined by where the baby was born or by whose names appear on the foreign birth certificate. Citizenship law, legal parenthood, genetic or gestational relationships, the intended parents' nationality and residence history, and the law of the country of birth can all affect the route.
It is important to separate three questions: Is the baby a citizen? Can the baby obtain a passport or other travel document? Who is legally recognised as the baby's parent? These issues are connected, but they are not the same.
The Quick Answer
After an international surrogacy birth, intended parents may need to establish the child's citizenship before applying for a passport. In some cases citizenship exists automatically at birth; in others the child may need to be registered or documented before travel is possible.
The safest approach is to establish the likely citizenship and passport route before treatment begins and confirm it again during pregnancy.
Citizenship, a Passport and Legal Parenthood Are Different
A passport is a travel document; it does not by itself decide every question of legal parenthood. Likewise, being named on an overseas birth certificate does not necessarily mean another country will recognise the named adults as the child's legal parents.
This distinction is particularly important for UK intended parents. UK guidance explains that foreign documentation does not automatically determine legal parenthood under UK law, and a British passport does not replace the parental-order process.

What Can Determine a Baby's Citizenship?
There is no single international rule. Depending on the countries and circumstances involved, authorities may consider:
- Where the baby was born.
- The citizenship of one or both intended parents.
- How an intended parent acquired their citizenship.
- The intended parents' previous residence or physical presence in their home country.
- Whether an intended parent has a genetic or gestational relationship with the baby.
- Who is regarded as the legal parent under the relevant law.
- The surrogate's marital status.
- Whether donor eggs or donor sperm were used.
- Whether citizenship must be registered rather than arising automatically.
Does the Baby Automatically Get Citizenship Where They Are Born?
Not necessarily. Countries have different nationality laws. In some surrogacy cases a child may not acquire citizenship or a passport from the country where they were born.
This is one reason country selection should involve legal planning as well as medical and financial considerations. Read what intended parents should consider before choosing a country for international surrogacy.
Documents You May Need
Exact requirements depend on the authority and case, but intended parents should be prepared to collect:
- The baby's local birth certificate.
- The intended parents' passports and birth certificates.
- Marriage or civil-partnership certificates where relevant.
- The signed surrogacy agreement.
- Clinic, fertility-treatment and relevant embryology records.
- Pre-birth or post-birth court orders.
- Evidence concerning the surrogate's identity and marital status.
- Required consent documents from the surrogate and, where relevant, her spouse.
- Evidence of residence or physical presence where nationality law requires it.
- DNA evidence where formally requested.
- Certified translations, notarisation, legalisation or apostilles where required.
When Can DNA Testing Be Required?
DNA testing can become relevant when citizenship or a passport depends on proving a biological relationship. Not every case requires it. If testing is requested, follow the authority's instructions because official processes may require an approved laboratory and controlled chain of custody.
Citizenship and Passports for UK Intended Parents
For UK families, the route depends on the facts of the arrangement. UK government guidance explains that a child born overseas through surrogacy may have an automatic claim to British citizenship in some circumstances, while other children may need to be registered as British citizens before a British passport can be issued.
When Might British Citizenship Be Automatic?
Current UK overseas-passport guidance gives an example in which a child born abroad through surrogacy may have an automatic claim before a parental order where the child is biologically related to the British intended father, that father is not British by descent, and the birth mother was not married at the time of birth. This is not a universal rule and individual facts need to be assessed.
When Might Registration as a British Citizen Be Needed?
UK guidance describes circumstances in which citizenship is not automatic and the child may first need to be registered as a British citizen. Registration can add significant time before travel documentation can be completed.
What Can HM Passport Office Ask For?
Evidence can include the signed surrogacy arrangement, fertility-treatment evidence, foreign court orders, surrogate consent, evidence of the surrogate's identity and marital status, the child's birth certificate, proof of the child's British nationality claim and identity documents for the intended parents.
HM Passport Office advises allowing substantially more time than normal for surrogacy cases. Current overseas guidance recommends submitting a surrogacy-related passport application at least four months before the passport is needed and states that a specific processing time cannot be guaranteed.
Does a UK Passport Make the Intended Parents the Legal Parents?
No. UK guidance distinguishes citizenship and travel documentation from legal parenthood. Even where an overseas-born child receives a British passport, intended parents generally still need to address legal parenthood under UK law.
For eligible families, a parental order is the principal mechanism for transferring legal parenthood after surrogacy. Read more in our international return-home guide.
Citizenship and Passports for US Intended Parents
The US Department of State determines a child's US citizenship when an application is made for a Consular Report of Birth Abroad (CRBA) or a US passport.
In surrogacy cases, officials may request evidence of conception and birth, genetic or gestational connections, identity and citizenship, the relevant US citizen's prior physical presence or residence in the United States, and legal parentage under local law.
Genetic, Gestational and Marital Connections
Current State Department guidance recognises several possible routes. Depending on the facts, the citizenship-transmitting parent may be a US citizen genetic father, a US citizen genetic mother, a US citizen gestational and legal mother, or in qualifying circumstances a US citizen parent married at birth to a parent who has the required genetic or gestational connection.
What Is a Consular Report of Birth Abroad?
A CRBA documents that an eligible child born overseas acquired US citizenship or US non-citizen nationality at birth. The State Department states that a CRBA does not itself serve as proof of the identity of the child's legal parents.

What If Citizenship Is Not Automatic?
If the child does not automatically acquire the intended parents' citizenship, an ordinary passport application may not be enough. Depending on the country and circumstances, the next step may involve citizenship registration, immigration or entry clearance, or another legal route.
How Long Can Citizenship and Passport Processing Take?
There is no universal processing time. Timing can be affected by birth registration, translations, DNA evidence, citizenship registration, consular appointments and requests for additional documents.
UK overseas-surrogacy guidance warns intended parents to prepare for a potentially lengthy stay because passport and immigration processes can take several months in complex cases.

Citizenship and Passport Checklist Before the Birth
- Identify which citizenship or citizenships the baby is expected to acquire.
- Confirm whether citizenship is automatic or requires registration.
- Confirm which parent is expected to transmit citizenship.
- Check whether genetic or gestational evidence will be relevant.
- Ask whether DNA testing may be requested.
- Confirm the passport or travel-document application route.
- Prepare birth, identity, marriage and citizenship records.
- Collect clinic, embryology and surrogacy documentation.
- Confirm what consent is needed from the surrogate or her spouse.
- Check whether documents require translation, notarisation or legalisation.
- Identify the relevant embassy or consulate.
- Budget for flexible flights and an extended overseas stay.

Finding Support for an International Journey
SurrogateFinder is a matching platform rather than a law firm, immigration adviser, medical provider or surrogacy agency. Intended parents still planning their journey can browse surrogate mothers, find surrogacy agencies and explore fertility clinics.
For international surrogacy, obtain independent legal advice in both the country where the baby will be born and the country where the intended parents plan to live.

Frequently Asked Questions
Does a baby born through international surrogacy automatically get the intended parents' citizenship?
Not always. Citizenship depends on the relevant nationality law and can be affected by parentage, genetic or gestational relationships, citizenship and residence history, and the circumstances of birth.
Can a baby get a passport before a parental order?
In some UK surrogacy cases, yes. HM Passport Office recognises applications before a parental order, but the nationality and parental-responsibility position must be established and additional evidence may be required.
Does a UK passport make intended parents the legal parents?
No. British citizenship or a passport does not by itself transfer legal parenthood. Eligible intended parents generally need a parental order to transfer legal parenthood under UK law.
Can DNA testing be required?
It can be requested where a genetic relationship is relevant to citizenship or documentation. Follow the authority's approved testing procedure.
What is a CRBA?
A Consular Report of Birth Abroad is a US document showing that an eligible child born abroad acquired US citizenship or US non-citizen nationality at birth. It is not itself proof of the identity of the child's legal parents.
How long can an international surrogacy passport application take?
There is no guaranteed universal timeframe. Complex cases can take months, particularly where citizenship registration, DNA evidence or additional documentation is required.
