When intended parents travel abroad for surrogacy and prepare to bring their child home, they frequently encounter a requirement that surprises them: proof of a genetic relationship between at least one parent and the child. This requirement does not originate with the fertility clinic. It arises from the immigration and nationality rules of the intended parents' home country, and sometimes from the consular procedures of the country where the child was born.
Understanding why this happens, what the testing process involves, and how to prepare for it will help you avoid delays at a critical moment. This guide sets out the practical realities as clearly as possible, though it does not constitute legal or medical advice. Always confirm current requirements with a qualified immigration lawyer and your nearest consulate before travelling.
Most countries that permit a surrogate-born child to acquire citizenship or residency through an intended parent do so on the basis of genetic parentage, not the act of carrying the pregnancy. A birth certificate naming you as a parent is persuasive, but it is not always sufficient for immigration purposes. Consular officers are trained to identify cases where a birth certificate may reflect legal parentage established in a jurisdiction whose family law is not recognised at home.
In practice, this means that even where a court order or parental order has been granted in the destination country, your home country's border agency or consulate may still require a DNA test to confirm that a biological link exists. As of writing, this is the position applied by several major receiving countries, though precise rules vary and are subject to change. We strongly recommend confirming the current position with local counsel before making any travel arrangements.
For intended parents who are not genetically related to the child — for example, where donor eggs and donor sperm were both used — the pathway is more complex and requires specialist legal advice at the earliest possible stage. You can learn more about how these arrangements are structured on our how it works page.
While it is not possible to publish a definitive and perpetually accurate list, the following broad patterns hold as of writing.
Our destinations guide provides country-by-country summaries, though you should treat these as starting points for your own due diligence rather than definitive legal guidance.
Immigration authorities do not accept DNA results from every laboratory. They typically require testing conducted by a laboratory that is accredited by a recognised body — in the United Kingdom this is the Ministry of Justice; in the United States, the American Association of Blood Banks (AABB) accreditation is the usual standard. Before arranging any test, confirm with your consulate or immigration lawyer which accreditations are acceptable.
The phrase "chain of custody" refers to the documented process by which samples are collected, labelled, stored and transported in a manner that prevents contamination or substitution. For immigration purposes, samples must normally be collected by an approved collector — not by the parents themselves or the fertility clinic — and sealed and shipped directly to the testing laboratory. Any break in this chain is likely to invalidate the result.
At minimum, the child and the intended parent claiming the genetic relationship are tested. Where both intended parents claim a genetic relationship (for example, where one contributed sperm and the other contributed eggs through a split donation arrangement), both may need to be tested. The surrogate is not routinely tested, as her genetic connection to the child is typically irrelevant for these purposes — and in most gestational surrogacy arrangements she has none.
Testing can sometimes be arranged shortly after birth, but logistics in overseas destinations can slow the process. Allow a minimum of several weeks from the date of birth to the point at which you have a certified result in hand, and build this into your travel planning. In some destinations, laboratories with the necessary accreditation are not locally available, requiring samples to be couriered internationally. This adds time and cost.
The cost of an accredited, chain-of-custody DNA test for immigration purposes is typically higher than a standard paternity test purchased commercially, because of the additional procedural requirements. As of writing, fees for a single parent-child test conducted to immigration standards range from a few hundred to over a thousand pounds or the local currency equivalent, depending on the laboratory, the country of collection, and courier charges. These costs are generally not included in agency or clinic packages and should be budgeted for separately.

A DNA result confirming parentage is rarely sufficient on its own. It is typically submitted alongside a package of documents that may include the child's birth certificate, hospital records confirming the birth, proof of the surrogacy arrangement (such as a notarised contract), evidence of egg or sperm donation where applicable, and the intended parent's own identity documents. Some consulates have a prescribed checklist; others assess applications on a case-by-case basis. Assembling this file methodically, and having it reviewed by a lawyer before submission, reduces the risk of avoidable delays.
Where neither intended parent has a genetic connection to the child — a situation that arises when both egg and sperm donors were used — the pathway to legal parentage and immigration clearance is more complex and varies significantly by country. Some jurisdictions may recognise the intended parents' legal parentage if it has been properly established in the birth country; others may not. This scenario requires early, specialist legal advice and should be discussed with your programme coordinator before treatment begins. Our frequently asked questions section addresses some common concerns in this area.
Immigration policy in this area is not static. Several countries have updated their procedures in recent years, and further changes are possible. The information in this article reflects the general landscape as of writing and should not be relied upon as current legal guidance. Verifying requirements with qualified legal counsel immediately before any application is not optional — it is essential.
