If your child was born in the UK, do they already have British citizenship or need to apply for it?
Mina’s parents thought she would need ILR before they could think about a British passport. Her father’s recent settlement grant made a different application worth assessing first.
The answer depends on the nationality law and the parents’ relevant status, not the birth certificate alone. Some children are British automatically at birth. Others may become entitled to registration when a parent later becomes British or settled while the child is still under 18.
This guide concentrates on that ordinary UK-born-child distinction, including registration under section 1(3) of the British Nationality Act 1981. It does not assume that every child needs ILR first or that a parent’s settlement automatically makes the child British. Establishing the existing nationality position comes before choosing a form.
Establish whether citizenship is automatic or requires registration
For a child born in the UK on or after 1 January 1983, a parent’s British citizenship or settled status at birth can establish automatic citizenship, subject to the applicable statutory provisions. Other bases and particular status histories can also matter.
Keep the full birth certificate and the evidence of the parent’s status at the relevant time. A current passport or later settlement grant may not, by itself, establish what was held on the birth date. EUSS histories can involve particular provisions and should be checked carefully where timing matters.
Our child ILR or citizenship guide explains the initial choice. If the child was already British, the task is generally to document that nationality through the appropriate process. Registration is not a necessary extra step simply because no British passport has yet been issued. Avoid paying for an application that assumes the child is not British before that has been established.
A UK-born child who was not British at birth can have an entitlement to registration under section 1(3) if a parent later becomes British or settled and the statutory conditions are met. The application must be made while the child is under 18.
One parent’s relevant status can establish this basis; it should not be confused with immigration settlement rules that may require the position of both parents to be addressed. The child does not generally need ILR first simply to use the section 1(3) entitlement.
The parent does not necessarily need to wait for their own citizenship. ILR can be the relevant change. Our citizenship after ILR guide explains the adult’s separate stage, while citizenship through marriage addresses another adult category. The child’s registration timetable should be assessed on its own legal basis rather than automatically postponed until the adults naturalise.
Follow a straightforward fictional example
Mina is a fictional child born in Birmingham in 2020. At birth, neither parent was British or settled, and the example assumes no other automatic nationality basis. Her father obtains ILR in October 2026 while Mina remains under 18.
The relevant next question is whether Mina meets section 1(3) and the other registration requirements. Her father’s ILR does not make her British automatically on the approval date. A successful registration is still needed. Her school attendance may help establish an ordinary fact about her life, but it is not the legal basis for this entitlement.
If Mina had instead been born after her father was already settled, the birth-status assessment could be different. The same family relationship and UK address can therefore lead to different processes depending on the relevant dates. That is why the parent’s grant and the child’s birth record should be examined together.
Mina’s evidence file has a full birth certificate recording Birmingham in 2020, the relevant parentage evidence and her father’s October 2026 ILR decision. Assume the parental identity chain is clear, the section 1(3) conditions are met and no other issue changes the ordinary position. The family can then prepare a registration application on that identified entitlement.
Mina is six in this example, so the age-ten good-character requirement does not apply to her present application. Her current immigration position and the relevant consent requirements are still checked separately. The family does not wait for her father’s naturalisation or buy child ILR simply because that was their original plan.
Check age and the requirements that follow from it
Section 1(3) is a minor’s registration entitlement. Do not assume that identifying the route before the eighteenth birthday is the same as making the application in time. The form, fee arrangements and actual submission process need to be completed correctly.
If affordability is an issue, children’s citizenship fee waivers explains the separate scheme and its timing provisions. Near an eighteenth birthday, obtain advice promptly rather than relying on an informal assumption about how the fee waiver and registration dates interact.
Other nationality routes can exist for a person born here, including a route based on the first ten years of life, but they have different requirements. This guide does not transfer those rules into section 1(3). If the ordinary minor’s entitlement is unavailable or the history is unusual, establish the appropriate legal basis before selecting an application.
The good character requirement applies from age ten to relevant child registration applications. A younger child should not be given an adult character analysis, but an older child’s entitlement should not be presented as removing the requirement.
Read citizenship and good character for the preparation and scope boundaries. Where there is an adverse matter, the child’s age, circumstances and current nationality policy require appropriate assessment. Do not assume an adult rule applies unchanged or that a parent’s good character answer covers the child.
For an ordinary application, answer the child’s questions accurately and obtain records where necessary. The purpose is to establish the actual position before submission. A significant adverse history or application depending on discretion may require advice beyond an ordinary Level 1 matter, even where the family initially describes the registration as straightforward.
Gather evidence of birth, parentage and the status change
The evidence should establish the child’s UK birth, relevant parentage and the parent’s later British or settled status. Keep the full certificate, appropriate identity records and the actual grant or nationality document. Check names and dates across them.
Our citizenship documents guide explains the general principle of selecting records by purpose, although an adult naturalisation checklist should not simply be copied for a child. The child’s application instructions and legal basis determine the specific evidence.
If a parent changed names or the records use different spellings, establish the chain clearly. Do not rely on the decision-maker recognising that two names refer to the same person without supporting evidence. A school record can help establish residence or identity context, but it cannot replace a required parentage record or grant. The document should prove the fact for which it is being supplied.
The family’s short evidence explanation gives each record a job: the certificate establishes UK birth and parentage; the grant establishes the later parental settlement; identity records connect the parent named on both. The application basis is the statutory entitlement, not a statement that Mina feels British or has attended a local school.
Deal with consent and immigration permission separately
Follow the child application’s consent requirements and address parental responsibility accurately. The form should reflect the real family arrangements. A missing parent, disagreement or uncertainty about who can consent should not be hidden by treating one signature as an administrative convenience.
Where the position is disputed or unusual, obtain advice appropriate to the issue. An ordinary nationality guide cannot resolve a family-law dispute. The evidence and legal basis for proceeding need to be established before submission.
Referees also need to meet the child criteria. British citizenship referees explains the professional connection normally required for at least one child referee and the current guidance where obtaining one is genuinely difficult. Ask early and follow the actual process. A teacher’s general praise letter should not be assumed to substitute for the prescribed declaration.
A registration application does not itself extend immigration permission or create section 3C leave. The child’s existing status and any expiry need separate attention while nationality is being considered. An entitlement to register is not the same as already holding British citizenship.
If the family uses work-route dependant permission, Skilled Worker dependant ILR explains the wider status planning. A child may need an appropriate immigration step while registration is pending, depending on the actual circumstances. Do not assume the parent’s ILR application automatically protects the child.
Record two conclusions where needed: the identified registration basis and the plan for current permission. That keeps the application sequence realistic. It also avoids delaying an immigration deadline while waiting for a nationality decision that does not, by itself, authorise the child’s continued stay.
Check the fee and the separate affordability scheme
The current ordinary child registration fee is £1,000. British citizenship fees explains the distinction from adult naturalisation and other costs. If the child turns 18 during processing, the applicable ceremony arrangements and fee need checking.
A family unable to afford the registration fee may qualify under the child citizenship affordability scheme. A looked-after child can instead have an exemption. A fee waiver decision concerns payment; it does not establish the registration entitlement or resolve the immigration position.
Check the approval letter and scheme-specific deadlines if a waiver is granted. The online child citizenship process uses different timing from an in-country immigration fee waiver. Applying the wrong token deadline can create avoidable work. The next application should be prepared around the correct scheme and the actual child’s circumstances.
Complete registration before treating it as a passport case
After successful registration, retain the citizenship certificate and check its details promptly. Citizenship certificates and first British passports explains the next process. A decision email, registration certificate and passport serve different purposes.
For a child born outside the UK, read children born abroad to a British parent instead of assuming the same section 1(3) route applies. Place of birth and the parent’s citizenship history can change the legal assessment substantially.
Knightsbridge’s British citizenship service assists with suitable ordinary child nationality matters. A Case Assessment should include the birth record, parents’ relevant status documents and the child’s current permission. The first useful answer is whether the child is already British, can use an identified registration entitlement or needs a different assessment before the family proceeds.
The supported next step for Mina is registration preparation, including its fee or separate affordability process. A first British passport becomes the next documentation question after registration is completed. That sequence explains both the application selected and why the initial ILR assumption changed.
