A parental order is the only route by which intended parents become the child’s legal parents under United Kingdom law. It is not a document you arrange in advance. It is an application to a court, made after the child is born, and the guidance sets a short window for making it.
Two things follow from that shape, and both of them belong in a plan before a cycle starts rather than after a birth. The first is a deadline. The second is that until the order is made, the child’s legal mother is the woman who carried them.
What the order does, and what it leaves alone
The regulator’s account is short and worth reading in full before you rely on anyone else’s summary of it.
- It moves legal parenthood from the surrogate to the intended parents. The same page states that once the order is made the surrogate has no further rights or obligations in relation to the child.
- It does not create parenthood at birth. The surrogate is the legal mother unless and until an order is obtained, and if she is married or in a civil partnership her spouse or partner is automatically the second legal parent.
- It does not make your agreement enforceable. The regulator’s own wording is that you can make an agreement beforehand, although it will not be legally binding.
- It does not by itself settle the child’s nationality or passport. Those are separate applications to separate authorities, with their own evidence requirements.
The last point is the one people are most often surprised by, because a birth in the United Kingdom does not automatically make a child British. Treat the order and the travel documents as two workstreams with different decision-makers.
The conditions a court applies
The official guidance lists the conditions as follows. Each is an item you can prepare evidence for, except the first, which is only a matter of being prompt.
- The time limit. You must apply within 6 months of the child’s birth. This is the constraint that makes a United Kingdom birth a scheduling problem as well as a legal one.
- Where the child lives. The child must be living with the applicants at the time the application is made.
- The genetic link. At least one of the applicants must be genetically related to the child, which the guidance spells out as being the egg or sperm donor. A gestational arrangement using donated eggs or donated sperm therefore has to be checked against this condition before treatment, not after.
- Residence. At least one applicant must reside permanently in the United Kingdom, the Channel Islands or the Isle of Man.
- Agreement. The surrogate, and her partner if she has one, must agree to the order. The guidance names the form the agreement is given on, which is A101A, and the application itself is made on form C51.
- Money. Payment to the surrogate is limited to reasonable expenses. Anything beyond that must be authorised by the family court before an order can be made, which is a point that has financial consequences long before a birth: an expense line nobody can characterise as reasonable is a problem sitting inside the application.
Read as a list, these are conditions about your situation rather than about the quality of the advice you received. That is why the questions to settle before choosing a destination matter more than a comparison of prices.
Where the six month window bites
The deadline is not the hard part. What makes it tight is everything that has to be true at the moment you file.
- The child has to be living with you, which means the plan for taking the child home is inside the application window rather than after it.
- The surrogate’s agreement has to be given, and an agreement made before birth is not binding, so the consent is being sought from a person who is under no obligation to give it.
- The expense question has to be answered with receipts. The United Kingdom position is a cap on reasonable expenses plus court authorisation for anything above it, so the paperwork about money is not optional administration; it is evidence in your own application.
- The court process itself takes time. The Law Commission’s project page states that the process typically takes six months to a year to complete after you apply, which is longer than the window in which you are allowed to apply.
If you are still outside that window for a reason you cannot control, ask a United Kingdom family lawyer what the options are rather than deciding from a blog. What is stated here is what the published guidance requires. It does not predict what a court will accept in a case it has not seen, and nobody who has not seen your file can do that either.
What was proposed, and where that stands
The Law Commission reported on 29 March 2023 with a draft bill intended to let intended parents become legal parents from the child’s birth, rather than applying to court afterwards, and to make certain arrangements enforceable in a limited way. The same page records that under the proposal the arrangements themselves would remain unenforceable in the sense a commercial contract is enforceable, and that the reform was framed as keeping surrogacy altruistic rather than commercial.
As of the government letter dated 10 April 2025 recorded on that page, reform is not currently a priority. So the six month rule and the conditions above are the system in force, and a plan built on the assumption that the new pathway will exist by the time of your birth is a plan with an unpriced risk in it.
If you are reading this because a destination page told you the United Kingdom is a place to give birth, note what the record on that page is about: the rules inside the United Kingdom, including who is a legal parent at birth. It is not a statement that the United Kingdom is a place where a surrogacy program can be arranged for you, and the destination record carries the sources for that distinction.
What to ask, and of whom
Take these to a United Kingdom family lawyer, in writing, before a clinic does anything irreversible.
- Does our arrangement satisfy the genetic link condition as the guidance states it, given which gametes are ours and which are donated?
- Who will hold the receipts for the surrogate’s expenses, and what does the agency’s fee structure do to the reasonable expenses characterisation?
- What is the plan for the child living with us within the six month window, including if the birth is early or the surrogate’s recovery is longer than expected?
- Who is responsible for obtaining the A101A agreement, and what happens to our application if it is withheld?
- Which authority will decide the child’s nationality and travel document, and what evidence will that authority ask for that the parental order does not produce?
Question five is where most cross border plans lose months, and it is almost never in the scope of a program description. The agency question checklist downloads as a document with room beside every question to write who answered it and when, which is the only form in which the answer is useful to you later.
The lines above describe the published rules and the state of the reform record. It is not legal advice, it is not a prediction about an application, and it is written for someone planning under United Kingdom law rather than for anyone’s specific case.

- [1]Legal rights when using surrogates or donors: become the child's legal parent
GOV.UK, Ministry of Justice guidance, published Apr 5, 2015 · checked Oct 16, 2026
Supports: That you must apply within 6 months of the child's birth, that the child must be living with the applicants, that at least one applicant must reside permanently in the United Kingdom, Channel Islands or Isle of Man, that one of them must be genetically related to the child, that the surrogate and any partner give agreement on form A101A, and that the application for the order itself is made on the C51 form.
- [2]Surrogacy (treatment information)
Human Fertilisation and Embryology Authority, published Apr 8, 2016 · checked Oct 16, 2026
Supports: That the surrogate is the legal mother at birth unless a parental order is obtained and her spouse or partner is automatically the second legal parent, that payment beyond reasonable expenses must be authorised by the family court before an order can be made, that an agreement made before birth is not legally binding, and that once the parental order is made the surrogate has no further rights or obligations in relation to the child.
- [3]Surrogacy (law reform project)
Law Commission for England and Wales, published Mar 29, 2023 · checked Oct 15, 2026
Supports: That intended parents must apply to court after the birth and the process typically takes six months to a year, that the final report proposed a pathway to legal parenthood from birth while leaving arrangements unenforceable, and the recorded government position of 10 April 2025 that reform is not currently a priority.
- [4]Check if you're a British citizen
GOV.UK, Home Office guidance · checked Oct 16, 2026
Supports: That being born in the United Kingdom does not by itself make a child a British citizen: the guidance states that citizenship by UK birth depends on where the parents were from and their circumstances, such as being a British citizen or holding indefinite leave to remain.
