Surrogacy and succession: What high-net-worth families need to knowLegal parenthood at birth Jemma Hotta, partner at Oury Clark, explains the position in England and Wales: “
In England and Wales, the surrogate will be the legal mother of the child at birth. If the surrogate is married, then their spouse will be the child’s father.”
For intended parents, particularly those who have invested emotionally and financially in a carefully planned surrogacy journey, that starting point can feel counterintuitive. Yet UK law does not prioritise genetics or private agreements at birth; instead, gestation and marital status are key factors.
The inheritance consequences are not symmetrical. Hotta continues: “If the surrogate (and potentially their spouse) does not have a will, the child will automatically be entitled to inherit a portion of the surrogate’s estate (provided their estate is large enough). However, the opposite is true for the intended parents. The child will not be entitled to inherit a portion of its intended parent’s estate unless and until a parental order is obtained.”
For families with substantial business interests, investment portfolios, property holdings or trust structures, that distinction is critical. In legal terms, a child born through surrogacy may have an automatic entitlement in relation to the surrogate’s intestate estate while holding no entitlement at all to the intended parents’ wealth until further steps are taken.
The importance of a parental orderThe mechanism that resolves this imbalance is a parental order. Hotta outlines the process: “
A parental order needs to be made in favour of the intended parents. This process involves an application to court and takes between 9 and 15 months to complete post-birth. Once a parental order has been made, this permanently ends the child’s legal relationship with the surrogate, and legal parenthood is assigned to the child’s legal parents.”
That timeline matters. A period of up to 15 months can elapse before legal parenthood is fully transferred and, during that window, vulnerabilities in succession planning may be exposed. As things currently stand, it isn’t possible for families to forward plan, as matters can’t be formalised in advance of the child’s birth. As Hotta makes clear: “A parental order can only be applied for after the child is born. There is no pre-birth legal process in England and Wales, and courts are not bound by a surrogacy agreement.”
For high-net-worth families, the absence of a pre-birth mechanism creates a certain vulnerability that must be factored into estate planning. If an intended parent were to die before a parental order is granted, the child’s position under the will or under intestacy rules could be uncertain, particularly where documents have not been updated to reflect the anticipated arrival.
Reviewing wills and historic trustsModern wills and trusts tend to reflect contemporary drafting practice. As Hotta notes: “In modern-day wills and trusts, a reference to your ‘children’ includes legitimate, illegitimate and adopted children (unless the will or trust expressly states otherwise).”
However, many substantial estates remain governed by historic instruments that were drafted in a different legal and social era. Hotta cautions: “Before 1950, adopted children were not within the definition of the adopter’s ‘children’. Historic trusts should therefore be considered to ensure that children born via surrogacy fall within the definition of potential beneficiaries.”
This point is particularly relevant for families with long-established trusts, landed estates or multi-generational structures, where capital and income pass through defined classes of beneficiaries. If the governing document contains narrow or outdated definitions, a child born via surrogacy may not automatically fall within scope.
Overseas arrangements and UK recognitionMany intended parents pursue surrogacy arrangements overseas, often in jurisdictions where contractual frameworks are more developed and processes appear more streamlined. Yet recognition in the UK is not automatic.
Hotta explains: “
Surrogacy agreements are commonplace overseas. However, they are not legally binding in the UK. Intended parents need advice from an immigration lawyer to make sure they can bring their child back to the UK and from a family lawyer to assist with the application for a parental order.”
For internationally mobile families, this introduces another layer of complexity. Immigration status, nationality and domicile can all intersect with tax planning and succession structures. A failure to secure appropriate advice at an early stage can delay legal recognition of parenthood and, in turn, complicate inheritance planning.
The limits of peerage reformIn aristocratic families like the Baths, succession is governed not only by private documents but by the law of peerage. Reform has been debated, but progress has so far been limited.
Hotta observes: “Over the last decade, there have been multiple iterations of bills proposed to vary peerage law, be that to eliminate gender discrimination in the inheritance of hereditary titles or to include children born via surrogacy. However, they have all failed to pass due to lack of time and disagreements on the impact of existing titles.
I therefore think that it is unlikely that peerage law is likely to change in the short-to-medium term, despite the rising use of IVF and surrogacy generally.”
