Not everyone who is entitled to British citizenship needs to go through the naturalisation route. Some people are already British citizens without realising it, and others have a legal right to be registered as British citizens based on their parentage, their circumstances at birth, or the way they were treated by previous nationality laws. These cases are often less straightforward than they first appear, but with the right advice, it is usually possible to establish exactly where someone stands.
Whether your entitlement comes through a British parent, a correction of historical nationality law, or another specific route under the British Nationality Act 1981, we are here to help you work through it clearly.

How Reeds Solicitors Can Help
Nationality by descent and registration cases involve a detailed assessment of parentage, dates of birth, the immigration status of parents at relevant times, and, often, the interpretation of historical nationality law. Small details can make the difference between entitlement and no entitlement, and an incorrect or incomplete application can result in a refusal that is difficult to challenge.
At Reeds Solicitors, we approach these cases methodically. We trace through the relevant nationality law, identify the correct route for your circumstances, advise on the evidence needed to establish each condition, and prepare a thorough application.
Our clients can expect:
- Entitlement assessment
We start by assessing whether you or your child is already a British citizen by descent or has a registration entitlement. We carefully work through the relevant parentage, dates, and immigration history. In some cases, this establishes that citizenship was already acquired automatically, in which case the next step is often to obtain evidence of citizenship, such as a British passport.
- Identifying the correct registration route
If registration is needed, we identify the correct route under the British Nationality Act 1981. There are multiple routes, each with different conditions, and choosing the wrong one can lead to unnecessary delays and costs. We make sure the application is targeted correctly from the outset.
- Evidence preparation
Registration applications require thorough documentary evidence covering the applicant’s birth, the parents’ nationality and immigration status at the relevant times, and, sometimes, the grandparents’ citizenship history. We advise on which documents are needed, help you obtain them, and ensure the evidence clearly establishes each required condition.
- Historical unfairness and discretionary applications
For applicants pursuing registration based on historical legislative unfairness, or on a discretionary basis, we advise on how the Home Office is likely to approach the application and how to present the case most effectively. These applications benefit significantly from careful legal preparation.
- Application management
We complete and review all application forms, compile the evidence bundle, advise on biometric enrolment, and manage communications with the Home Office throughout the process.

Nationality by Descent and Registration as a British Citizen
In many cases, a person born outside the UK on or after 1 January 1983 will automatically acquire British citizenship if, at the time of their birth, one parent was a British citizen otherwise than by descent. This means the parent was British by birth in the UK, through naturalisation, or through registration, but not themselves a British citizen by descent.
If a person is born outside the UK and their parent is also a British citizen by descent, the automatic transmission of citizenship stops at that generation. In those circumstances, registration may be available, but it is not automatic. The requirements depend on the applicant’s age, date of birth and the specific registration route available.
Children born before 1st July 1983 who may have missed out on citizenship because of rules that applied at the time may also have registration entitlements, including those born to British mothers before the law treated maternal and paternal citizenship equally.
Citizenship law depends heavily on the date of birth of both the applicant and their parents. Small differences in dates and family circumstances can produce different outcomes, which is why individual legal assessment is often necessary.
Registration is the process by which certain people who are not automatically British, or who have a specific entitlement under the British Nationality Act 1981, can apply to become British. It is different from naturalisation, which is the general route for settled residents.
The main registration routes include: children born in the UK who are not automatically British but whose parent became British or settled before the child’s 18th birthday; children born outside the UK to a British citizen by descent, where registration requirements relating to residence in the UK are met; adults who hold another form of British nationality such as British Overseas citizenship, British Overseas Territories citizenship, British National (Overseas) status, or British protected person status; people who were born in the UK before 1st July 2006 to a British or settled father and a mother who were not married, and who missed out on citizenship as a result; and people who renounced British citizenship in order to acquire or retain another nationality and wish to resume it.
Some registration routes are entitlements, meaning that if the conditions are met the application must be granted. Others are discretionary, meaning the Home Office retains discretion to refuse even where the conditions appear to be satisfied. Understanding which route applies to you, and how to evidence the conditions, is important.
UK nationality law has changed significantly over the decades, and there are a number of people who missed out on British citizenship because of rules that have since been widely criticised as unfair which Parliament has subsequently sought to address through changes to nationality legislation.
These include people who were born to British mothers before 1983, when citizenship passed only through the father; people born outside marriage whose British father was not recognised at the time; and those affected by the legacy of British colonial nationality law.
Recent legislative changes, including the Nationality and Borders Act 2022, created additional routes intended to address certain historical anomalies and unfairness in British nationality law. These are complex areas, and the eligibility criteria can be difficult to navigate without legal advice.
From 8 April 2026, the fee to register as a British citizen is £1,540 for adults. The fee for registering a child is £1,000, reduced from £1,214 as of the same date. A citizenship ceremony fee of £130 applies to adults following a successful registration application. The fees are non-refundable.
Frequently Asked Questions
It depends on how your parent became British and where you were born. If you were born outside the UK on or after 1st January 1983, and at the time of your birth, one of your parents was a British citizen other than by descent, subject to the nationality law applicable at the time of your birth, citizenship does not pass automatically to you, and you may need to apply to register. There are also rules relating to births before 1983 that work differently.
Citizenship by descent is acquired automatically at birth, where the conditions under the British Nationality Act 1981 are met. It does not require an application, though you will need to apply for a British passport to use it. Registration is a process by which certain people who are not automatically British apply to become British citizens. Registration can be an entitlement (granted if conditions are met) or discretionary (subject to the Home Office’s judgment).
Possibly, depending on the circumstances. If one of your child’s parents is a British citizen by descent, registration may be available before the child’s 18th birthday, provided the relevant residence or connection requirements are met. We assess the eligibility in each case individually, as the rules differ depending on the parent’s status and the child’s date of birth.
Possibly. Before 1st January 1983, British citizenship passed through the father only in most cases. Changes to nationality law have since introduced registration routes for some people who missed out as a result. The eligibility criteria are specific and depend on your individual circumstances, so this is an area where legal advice is particularly important.
From 8 April 2026, the fee to register as a British citizen is £1,540 for adults and £1,000 for children. A citizenship ceremony fee of £130 applies to adults following a successful registration. The fees are not refunded if the application is refused.
Important: Registration fees and Home Office policies may change. Applicants should check the latest GOV.UK guidance before making an application.
Processing times vary. Straightforward registration applications are generally processed within several months. More complex cases, including those involving historical nationality law or discretionary registration, can take longer. We advise on expected timescales at the time of your application.
The good character requirement applies to applicants aged 10 or over. The Home Office will consider criminal history, immigration record, financial matters, and honesty in previous dealings with the Home Office. For children under 10, the requirement does not apply.
The documents needed depend on the specific route, but typically include:
- Your full birth certificate
- Your parents’ birth certificates, naturalisation or registration certificates establishing their citizenship
- Passports covering the relevant periods
- Evidence of any relevant marriage certificates
- Documentary evidence of residence in the UK if a residence requirement applies
We advise in detail on the evidence needed once we have assessed your specific circumstances.
