Is My Child Born in the UK Automatically British?

Parents are often understandably confused about the nationality of a child born in the UK. A common assumption is that birth on UK soil automatically makes a child British. While this used to be the case, this is no longer the law.

The UK abolished automatic citizenship by birth (jus soli) with the introduction of the British Nationality Act 1981, which came into force on 1 January 1983. Since then, a child’s British citizenship has depended primarily on the immigration or nationality status of their parents at the time of birth, rather than the place of birth alone.

This article explains the most common scenarios we advise on at Lace Law, using practical examples and clear references to the relevant law, to help parents understand whether their UK‑born child is British – or what steps may be needed to make them British.

The Legal Framework (in brief)

British citizenship for children born in the UK is mainly governed by the British Nationality Act 1981 (BNA 1981).

The key concept is whether at least one parent was ‘settled’ in the UK at the time of birth. A parent is usually considered settled if they:

• Hold Indefinite Leave to Remain (ILR), or

• Have Settled Status under the EU Settlement Scheme, or

• Are a British citizen.

  
  

If neither parent was settled at the time of birth, the child is not automatically British, but may still have routes to register as a British citizen later.

Scenario 1: Child Born in the UK to Parents Without Settled Status

Example scenario

Maria (Brazilian national) and Carlos (Mexican national) are living in the UK on Skilled Worker visas. On 15 March 2022, their daughter Sofia is born in London. At the time of Sofia’s birth:

• Neither parent has ILR or settled status

• Neither parent is British

Is the child British at birth?

No.

Under section 1(1) BNA 1981, a child born in the UK is only British at birth if at least one parent is settled or British at the time of birth. This condition is not met here.

What is the child’s immigration position?

Sofia does not automatically have British citizenship. In practice, she will usually be granted immigration permission in line with her parents (for example, as a dependant).

Potential legal solution

If, in the future, one parent becomes settled, Sofia may be eligible to register as a British citizen under section 1(3) BNA 1981 (see Scenario 2 below).

Alternatively, long residence in the UK may open other registration routes depending on circumstances. Children born in the UK who live there for the first 10 years of their life (with limited absences) can register as British citizens under section 1(4) BNA 1981.

Scenario 2: Child Born in the UK – Parents Become Settled Later

Example scenario

Wei (Chinese national) and Ling (Chinese national) are in the UK on student and later Skilled Worker visas. Their son Daniel is born in Manchester on 10 June 2019.

At the time of Daniel’s birth:

• Neither parent has ILR or settled status

  
  

On 1 September 2024, Wei is granted Indefinite Leave to Remain.

Is the child automatically British?

No – but an important option becomes available.

Daniel is not British automatically, because neither parent was settled at the time of his birth.

Daniel can now apply to register as a British citizen under section 1(3) BNA 1981, because:

• He was born in the UK, and

• One parent has since become settled

  
  

This is a discretionary registration application, made using Form MN1.

Once registered, Daniel becomes British from the date of registration (not retrospectively from birth).

Scenario 3: Child Born in the UK to Parents With Settled Status

Example scenario

Anita (Indian national) and Raj (Indian national) both hold Indefinite Leave to Remain.

Their daughter Maya is born in Birmingham on 5 February 2023.

Is the child British at birth?

Yes.

Under section 1(1) BNA 1981, Maya is automatically a British citizen because both parents were settled at the time of her birth (it is sufficient for only one parent to be settled).

Important practical point

Although Maya is British by law, British citizenship is not evidenced automatically. To prove her status, her parents must apply for a British passport.

Proving British Citizenship: The British Passport Application

If a child is automatically British at birth, the correct next step is not naturalisation or registration, but a British passport application.

Key points:

• An online application is made to HM Passport Office

• Evidence usually includes:

  • The child’s UK birth certificate

  • Proof of the parent’s settled status or British citizenship at the time of birth

  • Parents’ identity documents

    
    

The parents need to send original documents to prove the identity of their child, and their immigration status.

A successful passport application confirms and evidences the child’s British nationality.

Scenario 4: Child Born in the UK With One British Parent

Example scenario

James (British citizen) and Lucia (Argentinian national with limited leave) live in the UK.

Their son Oliver is born in Leeds on 12 August 2021.

Is the child British?

Yes, automatically.

Under section 1(1) BNA 1981, a child born in the UK is British at birth if either parent is a British citizen, regardless of the other parent’s immigration status.

What should parents do next?

Oliver is British from birth. His parents should apply directly for a British passport to evidence his citizenship.

Key Takeaway: Settled Status is Crucial

To summarise:

• A child is automatically British at birth only if at least one parent is British or settled at the time of birth

• If parents become settled after the child is born, the child may be able to register as British

• Being born in the UK alone is not enough

  
  

Every family’s circumstances are different, and the correct route depends on timing, immigration status, and future plans.
