Form C51 is the application that opens your Parental Order case at the Family Court. It looks like a routine court form; it is actually the document where international surrogacy families most often create problems for themselves — usually through small, avoidable gaps. Here's what each part is really asking, and where to take care.
Before you start: three facts about C51
You file it yourselves. In international cases it's typically the Intended Parents who complete and submit the form — by email to the Central Family Court, with the child's birth certificate and (if applicable) your marriage or civil partnership certificate attached. It can't be filed until the birth certificate is in hand — but almost everything else can be drafted while you wait, even before the birth. It must be filed within 6 months of the birth — the statutory deadline everything else is planned around.
The applicants — more than name and address
The form asks for full names, addresses, dates of birth, occupations and your relationship to each other. Two details deserve special attention in international cases:
- Genetic connection. At least one applicant must be genetically related to the child — this is an absolute statutory requirement under s.54. If neither applicant is genetically related (a double-donor arrangement), a Parental Order cannot be made, and you need urgent legal advice on alternative routes.
- Domicile. At least one of you must be domiciled in the UK, Channel Islands or Isle of Man. Domicile is a legal concept that isn't the same as residence — if you've lived abroad extensively, this is one area where specialist advice is genuinely worth considering.
The child's details
Name as registered on the foreign birth certificate, date and place of birth, and the name your child will have if the order is made. International detail that trips families up: the court works from the foreign birth certificate (with certified translation where needed), so its details must match what you enter exactly.
The surrogate (and her spouse)
The form needs your surrogate's details and — a frequent surprise — those of her spouse or civil partner if she has one, because they may also be a legal parent under UK law. Her address can raise confidentiality questions in some arrangements; there are mechanisms for this (such as Form C8) where her details can be kept confidential from the other parties.
Payments — the section to get completely right
C51 requires disclosure of all payments made in connection with the surrogacy. UK law permits "reasonable expenses"; in practice, international arrangements often exceed that, and the court routinely authorises payments retrospectively. What the court cares about is transparency: list every payment with dates and amounts, even those above typical expense levels. Gaps and vagueness invite questions; full disclosure, in our experience, does not put the order at risk in the way families fear.
What gets applications returned
The patterns we see repeatedly: incomplete payment disclosure; details that don't match the birth certificate or supporting documents; missing certified translations; and filing so close to the deadline that a returned form becomes a crisis. None of these are legally complex — they're checklist failures, which is exactly why a structured walk-through of every field pays for itself.
