British Citizenship by Marriage

Last reviewed: 9 October 2026. Fees and requirements checked against GOV.UK.

Can you become a UK citizen by marriage?

Not automatically. Marrying a British citizen, or entering a civil partnership with one, does not make you British, and it does not give you a British passport. You normally need indefinite leave to remain or settled status first, and then a successful naturalisation application of your own.

What marriage does is shorten the route. Under section 6(2) of the British Nationality Act 1981, the spouse or civil partner of a British citizen can apply after three years' residence instead of five, as soon as they hold indefinite leave to remain or settled status. The sequence looks like this:

1. Marry or enter a civil partnership with a British citizen.
2. Get indefinite leave to remain, settled status or indefinite leave to enter, if you do not already have it.
3. Apply to naturalise on the spouse route once you meet the three-year residence and absence rules.
4. If the application is granted, attend a citizenship ceremony. You must attend within 3 months of receiving your invitation, and you receive your certificate of British citizenship at the ceremony.
5. Only then apply for your first British passport, using your naturalisation certificate.

Marriage does not start a three-year clock to citizenship. The three years only help once you also meet the settlement or immigration status requirements. If you came to the UK on a spouse or partner visa, you will generally need to complete that five-year route and get indefinite leave to remain before you can apply to naturalise (GOV.UK, Family visas: partner and spouse).

If you have been granted and are waiting for the ceremony, our guide to your British citizenship decision letter explains what happens next.

The three-year spouse route in 2026

If you are married to or the civil partner of a British citizen, you do not have to wait as long as most applicants. The three-year route is shorter, has no waiting period after settlement, and drops one requirement entirely.

It is also widely misunderstood. People assume marriage makes them British, or that it removes the need for settled status. It does neither. It changes the timetable, and for many couples that saves a year or more.

Three ways the spouse route differs

Everything else is the same as the standard naturalisation route. These are the differences that matter:

The last row is the one almost nobody mentions. The future intentions requirement, that you intend your principal home to be in the UK, applies to applicants under section 6(1). It does not apply to spouses and civil partners applying under section 6(2). In practice, you will not be asked whether the UK will be your principal home after you naturalise. That does not mean time abroad stops mattering. The residence and absence requirements still apply in full: you must have been in the UK exactly three years before the Home Office receives your application, and your time outside the UK is counted against the limits below.

On absences, the yearly rate is the same on both routes: roughly 90 days a year. The difference is that you reach the finish line two years sooner.

Who qualifies

You can apply on this route if, on the date the Home Office receives your application, all of the following are true:

• You are 18 or over.
• You are married to, or the civil partner of, a British citizen.
• You hold indefinite leave to remain, settled status or indefinite leave to enter (some people with pre-settled status may also qualify; see below). There is no minimum period you must have held it.
• You have lived in the UK for at least three years before the date of application.
• You were physically in the UK on the day exactly three years before the Home Office receives the application.
• You have not spent more than 270 days outside the UK in those three years, or more than 90 days in the last twelve months. These are the standard limits; the Home Office can accept more in some cases (see Counting your absences).
• You are of good character.
• You meet the English language requirement and have passed the Life in the UK test.

If you have pre-settled status rather than settled status, you may still be able to apply in some cases. GOV.UK says this can apply if you are from the EU, Norway, Iceland or Liechtenstein (or are the family member of someone who is), you started living in the UK by 31 December 2020, and you have lived in the UK for 5 years in a row, working (or looking for work for up to 3 months), studying or being self-sufficient during that time.

Your spouse must be a British citizen, not just settled

This is the misunderstanding we see most often. Your partner must actually hold British citizenship. If they have indefinite leave to remain but have not naturalised, the three-year route is not open to you. You fall back on the standard five-year route, with its twelve-month wait after settlement.

Where both partners are eligible, it can make sense for one partner to naturalise first, which then opens the shorter route to the other. Whether that is quicker overall depends on your own dates, so it is worth working through before either of you applies.

The marriage must be valid, and it must still exist

The Home Office needs a marriage or civil partnership recognised under UK law. Religious ceremonies that were not registered under the law of the country where they took place cause regular problems, as do divorces from earlier marriages that were never properly finalised.

You must still be married or in the civil partnership on the date of application. There is no minimum length of marriage. A marriage that has broken down, or one the Home Office believes was entered into for immigration purposes, raises issues under good character rather than under the relationship rules.

If your British partner has died, you cannot apply on the spouse route, but you may be eligible another way, for example on the standard route with indefinite leave to remain.

Counting your absences

The 270-day limit is the requirement that most often trips people up on this route, because it is tighter in absolute terms than the 450 days allowed over five years.

Count every trip: weekend breaks, family visits, work travel. The 270-day and 90-day figures are the standard limits, not automatic cut-offs. Going over them does not automatically mean your application will be refused. The Home Office has discretion to disregard excess absences in appropriate circumstances, looking at how far over you are, your ties to the UK and why you were away (GOV.UK, Form AN guidance: absences from the UK). Even so, if you are close to the limit, waiting a few months is often safer than relying on that discretion.

If a naturalisation application is refused, the £1,709 application fee is not refunded, but the £130 citizenship ceremony fee is (GOV.UK, Fees for citizenship applications).

Check the last twelve months separately. You can be comfortably inside 270 days over three years and still go over the 90-day limit in the final year. The Home Office looks at that limit on its own, so it needs its own explanation.

Good character, English and Life in the UK

These are identical to the standard route. Marriage to a British citizen gives you no extra leeway on any of them.

Good character covers criminal convictions and cautions (including spent ones, which must still be declared for nationality purposes), fixed penalty notices, driving offences, immigration breaches, unpaid tax and any deception in an earlier application. Having one of these on your record does not automatically mean refusal. Each is assessed against the Home Office's good character guidance, which looks at what happened, when, and how serious it was. Fixed penalty notices for things like speeding or parking, for example, must be declared but are not normally taken into account unless you failed to pay and there were criminal proceedings, or you received several in a short space of time (GOV.UK, Form AN guidance: good character).

Declare everything and explain it. A disclosed issue can often be dealt with. The same issue found by the Home Office after you left it out can be treated as deception. See GOV.UK, Good character: caseworker guidance.

English must be shown at CEFR B1 or above, for example through an approved English language qualification, a degree taught or researched in English, or nationality of a majority English-speaking country. Exemptions apply if you are 65 or over or have a qualifying long-term physical or mental condition.

The Life in the UK test has 24 questions and you need 75% to pass. If you passed it for your settlement application, that pass still counts. Keep the reference number.

What it costs

The fee is the same as on the standard route. According to the Home Office immigration and nationality fees, 8 October 2026 (updated 10 September 2026):

• £1,709 naturalisation application fee
• £130 citizenship ceremony fee
• £1,839 in total

GOV.UK's spouse route page quotes the same total of £1,839. Fees change, so check the current figure on GOV.UK before you pay.

GOV.UK says you will usually get a decision within 6 months, though some applications take longer. If you want to understand decision times in more detail, see our guide to the timeline for British citizenship application decisions.

What you will need to provide

• Your passport and any previous passports covering the three-year period
• Your marriage or civil partnership certificate
• Evidence that your spouse is a British citizen, such as their British passport or certificate of naturalisation or registration
• Proof of your own indefinite leave to remain or settled status, including your eVisa or UKVI account details
• Your Life in the UK test reference and English language evidence
• A complete list of absences with dates, using your own records such as boarding passes and emails
• Evidence of residence across the three years, such as employment, tax, tenancy or mortgage, council tax or GP records
• Details of two referees who have each known you for at least three years. One must be a professional person; the other must hold a British passport and be either a professional person or over 25. Neither can be related to you or to each other, or be your representative on the application (GOV.UK, Form AN guidance: referees).

You can apply online and give your fingerprints and photo at a UKVCAS appointment (GOV.UK, How to apply).

Where these applications go wrong

• The spouse has ILR, not citizenship. The route is simply not available, and the application fails.
• Absences over 270 days with no good explanation. Often by a small margin, and usually because short trips were not counted.
• The 90-day rule in the final year. Overlooked because the three-year total looked comfortable.
• A marriage not recognised under UK law, or an earlier divorce that was never properly completed.
• Undeclared minor matters. A fixed penalty or a spent caution left out as irrelevant and then treated as deception.
• Not being in the UK on the qualifying date exactly three years before the application is received.
