Section 4C Citizenship: Registration for Those Born Before 1983
Section 4C of the British Nationality Act 1981 exists to correct a historical injustice. Before 1983, British citizenship could only be passed automatically through the father, not the mother. Section 4C allows those affected by this gender discrimination to register as British citizens.

In short
- Section 4C corrects gender discrimination in pre-1983 nationality law.
- It applies to people born before 1 January 1983 to British mothers.
- Registration is simpler than naturalisation but still requires good character (for applicants aged 10 or over).
- There is no residence requirement and no application fee for Section 4C registration; only the £130 ceremony fee is payable.
Section 4C allows people born before 1983 to register as British citizens if they would have been citizens had the law treated their mother's citizenship the same as their father's. This corrects historical gender discrimination in nationality law. This guide explains who qualifies and how to apply.
The Historical Injustice
Before 1 January 1983, British nationality law discriminated between mothers and fathers. A British father could automatically pass citizenship to his children born abroad, but a British mother generally could not. This meant that thousands of people born abroad to British mothers were denied citizenship that they would have had if their British parent had been their father instead.
Section 4C of the British Nationality Act 1981 was introduced to correct this. It allows affected individuals to register as British citizens. GOV.UK explains the route on its citizenship for people born before 1983 with a British parent page.
Who Is Eligible
You may be eligible for Section 4C registration if:
- You were born before 1 January 1983
- You would have been a citizen of the UK and colonies (CUKC) by descent, or would have had the right of abode, if the law had treated your mother's citizenship the same as your father's
- You would have become a British citizen on 1 January 1983 when the British Nationality Act 1981 came into force, had you been a CUKC
Common scenarios include:
- Born abroad to a British mother and a non-British father before 1983
- Born abroad to a British mother who was married to a non-British father (marriage was particularly relevant under the old rules)
No Residence Requirement
Unlike naturalisation, Section 4C registration does not require you to have lived in the UK. You can apply from anywhere in the world. There are no absence limits to meet, no minimum period of residence, and no requirement to hold settlement (indefinite leave to remain) or any other immigration status.
This makes Section 4C significantly more accessible than the standard naturalisation route for those who qualify.
Good Character Requirement
Applicants aged 10 or over under Section 4C must still meet the good character requirement. This is the same assessment used for naturalisation applications and considers criminal record, immigration history, and general conduct.
The Home Office nationality guidance says the requirement applies to registration applicants aged 10 or over. Because everyone eligible under Section 4C was born before 1983, in practice it applies to every Section 4C applicant.
How to Apply
Applications are made using form UKM, available on GOV.UK. There is no application fee; you pay only the £130 citizenship ceremony fee. GOV.UK says a decision usually takes up to 6 months. You will need to provide:
- Your full birth certificate (one that includes the name of your parent or parents)
- Evidence of your mother's British citizenship or citizen of the UK and Colonies status (for example a naturalisation certificate or an expired passport)
- Your mother's full birth certificate
- Your current passport
- Marriage certificates where family names differ between generations, and evidence of your parents' marriage (the old law treated married and unmarried parents differently)
Documents not in English need certified translations.
The Ceremony
If you are aged 18 or over when the decision is made, you will need to attend a citizenship ceremony after your application is approved, within 90 days of being invited, and pay the £130 ceremony fee. If you are outside the UK, the Guide UKM says ceremonies are held at a British embassy, high commission, consulate, or a Governor's or Lieutenant-Governor's office. Not attending without a valid reason results in the application being refused.
After Registration
Once registered as a British citizen, you have exactly the same rights as any other British citizen. You can:
- Apply for a British passport
- Live and work in the UK without restriction
- Vote in UK elections (if resident in the UK)
- Pass citizenship to your own children (subject to generational limits for those born abroad)
Impact on Your Children
If you register as a British citizen under Section 4C, your children may also have a claim to citizenship, particularly if they were born before you acquired citizenship. The rules on citizenship by descent apply.
Seek specialist advice if you have children who may benefit from your registration, as the generational limits on passing citizenship abroad can be complex.

Questions and answers
What is Section 4C citizenship?
Section 4C of the British Nationality Act 1981 allows people to register as British citizens if they would have automatically become citizens had the law treated mothers and fathers equally. Before 1983, citizenship could generally only be passed through the father. Section 4C corrects this historical gender discrimination.
Who is eligible for Section 4C registration?
You may be eligible if you were born before 1 January 1983 and would have been a citizen of the UK and colonies (or a British citizen) if the law had allowed citizenship to pass through your mother in the same way as through your father. This typically applies to people born abroad to British mothers.
Is there a good character requirement for Section 4C?
Yes. The Home Office applies the good character requirement to Section 4C applicants aged 10 or over (everyone eligible under Section 4C was born before 1983, so in practice all applicants). This is the same assessment used for naturalisation applications, covering criminal record, immigration history, and general conduct.
How much does a Section 4C application cost?
There is no application fee for registration under Section 4C (or Sections 4G to 4I). GOV.UK lists these applications as 'ceremony fee only': you pay £130 for the citizenship ceremony, which applicants aged 18 or over must attend. By comparison, naturalisation costs £1,839 and standard adult registration £1,540 plus the £130 ceremony fee.
