Applying for a Child’s British Citizenship When the Parent Gained Settled Status After Birth

It’s very common for parents to feel unsure about their child’s nationality position when the child was born in the UK before the parent obtained settled status. The rules can feel technical, and many parents worry they may have missed a crucial deadline.
Understanding how the British Nationality Act works — and when a child becomes entitled to register — can help you move from uncertainty to clarity.

This guidance explains your child’s eligibility, how section 1(3) of the Act works, and the steps you can take to apply confidently.

Understanding the Issue or Context

A child born in the UK does not automatically become British unless at least one parent is:

  • British at the time of birth, or
  • “settled” (for example, holding ILR or settled status) at the time of birth

If a parent obtains settled status after the child is born, the child may still have a right to British citizenship — but it takes a different legal route.

Many parents are unsure whether they can still apply or whether they must wait. The right pathway depends on understanding the registration process under the British Nationality Act 1981.

The Legal Rules or Framework

Section 1(3) of the British Nationality Act 1981

A child is entitled to be registered as a British citizen if:

  • they were born in the UK, and
  • at least one parent becomes settled in the UK after the child’s birth

This is an entitlement, not a discretionary application.
If the legal criteria are met, the Home Office must register the child.

Who Counts as “Settled”?

For this purpose, “settled” includes:

  • Indefinite Leave to Remain (ILR)
  • Indefinite Leave to Enter
  • Settled status under the EU Settlement Scheme

You obtained settled status in June 2024, which counts.

Timing Rules

The law does not require the parent to have been settled at birth.
Citizenship becomes available once:

  • the child is still under 18, and
  • the parent has obtained settled status

Your child (born March 2023) meets both requirements.

Outcome of Registration

If the application is successful, your child becomes a British citizen and can then apply for a British passport.

Practical Steps to Take (Step-by-Step Guidance)

1. Confirm Eligibility

Based on the facts:

  • Child born in the UK (22 March 2023)
  • You obtained settled status on 19 June 2024
    This meets the requirement under section 1(3).

2. Prepare the Required Documents

You will normally need:

  • Child’s full UK birth certificate
  • Your settled status evidence (e.g., share code or Home Office grant letter)
  • Proof of your identity (passport)
  • Proof the child is living in the UK (GP letter, nursery letter, etc.)

The Home Office sometimes requests additional documents, depending on the circumstances.

3. Apply Using Form MN1

Applications are made online using the MN1 form.
This is the form for children entitled to registration.

4. Pay the Fees

There is a set Home Office fee for registration applications.
The fee does not change depending on how long the child has lived in the UK.

5. Attend a Biometric Appointment (If Requested)

Many children under 5 do not need fingerprints, but a photo is normally required.

6. Receive the Citizenship Certificate

If the application is approved, your child will receive a certificate of registration.

7. Apply for a British Passport

Once registered, they are fully British and can apply for a passport.

Common Pitfalls to Avoid

  • Assuming the child must wait until adulthood
    Section 1(3) applies immediately once a parent becomes settled.
  • Believing that only British parents can pass citizenship
    Settled status is enough, even if you were not settled at birth.
  • Using the wrong application route
    A passport application cannot be made until citizenship is granted.
  • Not providing evidence of your settled status
    The Home Office must confirm your status before approving the child’s registration.
  • Delaying unnecessarily
    The entitlement exists only while the child is under 18.

Frequently Asked Questions

1. Can I apply for my child’s citizenship even though I became settled after they were born?

Yes. Section 1(3) of the British Nationality Act 1981 covers this exact situation.

2. Does the other parent need to be settled or British?

No. Only one parent needs to have become settled after the child’s birth.

3. Does my child need to meet residence requirements?

No. There is no minimum residence period for section 1(3) entitlement.

4. Can my child apply directly for a passport?

Not yet. They must first be registered as British using Form MN1.

5. Will the Home Office refuse the application?

If the legal criteria are met, this is an entitlement application — the Home Office must approve it.

6. What happens if I wait until my child turns 18?

Section 1(3) no longer applies once the child becomes an adult.
A different, discretionary route would then be needed.
