British Citizenship by Marriage
Married to a British citizen? Our immigration solicitors guide you through the 3-year route, good character rules and the citizenship ceremony — so your application gets it right first time.
If you are married to, or in a civil partnership with, a British citizen, you can apply for British citizenship after just three years’ continuous UK residence — two years earlier than the standard five-year route — provided you have held Indefinite Leave to Remain (ILR) or settled status for at least 12 months and meet the other naturalisation requirements. Marriage or civil partnership to a British citizen does not grant citizenship automatically or speed up your immigration status on its own; it accelerates the residence requirement for naturalisation once you already hold ILR. Adam Bernard Solicitors advises spouses and civil partners across London and internationally through every stage of this route, from the initial spouse visa through to the citizenship ceremony
Am I eligible for the 3-year marriage route?
You qualify for the accelerated three-year route if you are legally married to, or in a civil partnership with, a British citizen and meet six conditions. You must:
- Be aged 18 or over
- Be married to, or in a civil partnership with, a British citizen (civil partnerships qualify on exactly the same terms as marriage — same-sex and opposite-sex couples are treated identically)
- Have held Indefinite Leave to Remain (ILR) or EU Settled Status for at least 12 months before applying
- Have lived continuously in the UK for three years, with no more than 270 days outside the UK during that period and no more than 90 days in the 12 months immediately before applying
- Meet the English language requirement at CEFR level B1, unless exempt, and pass the Life in the UK Test
- Satisfy the “good character” requirement
If you’re not yet married to a British citizen but are considering the spouse or partner visa as a first step, this three-year naturalisation route is generally the fastest realistic path to full British citizenship available to a foreign spouse.
What if the marriage ends, or my spouse dies, before I apply?
If your marriage or civil partnership ends, or your sponsoring spouse dies, before you complete the three-year qualifying period, you generally lose eligibility for the accelerated route and fall back to the standard five-year residence requirement — but existing time spent in the UK still counts. Specifically:
- Divorce or dissolution before the 3-year point: you can still apply once you reach the standard 5-year continuous residence requirement (measured from when your qualifying leave began, not restarting from zero), provided you otherwise meet the eligibility criteria in your own right
- Death of the sponsoring spouse: the Home Office retains discretion to continue treating a case sympathetically where the marriage was genuine and subsisting until death, but this is assessed case by case — early legal advice matters here, since the standard guidance doesn’t set out a fixed rule
- Separation without divorce: a marriage must be subsisting for the 3-year route to apply; if you are separated but not divorced, the Home Office may query whether the relationship is genuinely ongoing
If your relationship has changed since you obtained ILR through your spouse or partner, get advice before submitting Form AN — applying under the 3-year route when the marriage has in fact ended can itself raise a good character or deception concern.
What is the "good character" requirement — and how does it interact with a marriage-based application?
You must satisfy the Home Office that you are of good character, and on the marriage route this includes specific scrutiny of whether the marriage itself is genuine. Under Home Office good character guidance, applications are normally refused where an applicant has:
- Been sentenced to four years or more in prison (an effectively permanent bar)
- Been sentenced to between 12 months and four years, where the sentence ended within the last 15 years
- Been sentenced to under 12 months, where the sentence ended within the last 10 years
- Committed an immigration offence — including facilitating or entering into a sham marriage under section 24 or 24A of the Immigration Act 1999 — which is assessed under its own lookback period and can affect both the applicant and, in some cases, the sponsoring spouse
- Concealed or refused to disclose relevant convictions, cautions or immigration history
How much does it cost to apply for citizenship by marriage in 2026?
The application fee is the same £1,839 naturalisation fee that applies to every adult Form AN application — the 3-year marriage route is not a separate or discounted fee category.
| Fee | Amount | Notes |
|---|---|---|
| Naturalisation (Form AN) | £1,839 | Non-refundable even if refused; same fee whether applying via the 3-year or 5-year route |
| Life in the UK Test | £50 | Paid to Pearson VUE, separately |
| Citizenship ceremony | Included in the £1,839 fee for a standard group ceremony | Many local authorities charge attendees an additional administrative fee (typically £80–£150) to attend – this is set by the council, not the Home Office, so check with the authority named in your invitation |
| Reconsideration of a refused application (Form NR) | £513 | See below |
(Figures confirmed against the GOV.UK fee schedule current at the time of writing; the Home Office periodically revises fees, so always check GOV.UK’s fee page or ask us to confirm the live figure before you pay.)
The citizenship ceremony: format, exemptions and the "Zoom" question
There is no general option to attend a UK citizenship ceremony remotely by video call — almost everyone approved for citizenship must attend an in-person ceremony at their local council within three months of being invited. The only people exempt from attending in person are those registering as a British Overseas Territories citizen, a British Overseas citizen, or a British subject — and even they must still take the oath or affirmation of allegiance by an alternative method the Home Office specifies to them directly; there is no generally available Zoom or online ceremony for standard naturalisation applicants. If you have a genuine medical or exceptional circumstance that prevents you attending, contact the local authority named on your ceremony invitation directly, as some authorities can arrange a private ceremony (usually at extra cost) or, in limited cases, a home or bedside ceremony — this is decided locally, not by the Home Office.
What documents do I need, specifically for the marriage route?
In addition to the standard naturalisation documents (identity, immigration history, absences, Life in the UK Test pass, referees), the marriage route typically also requires:
- Your marriage certificate or civil partnership certificate
- Evidence the marriage or civil partnership is genuine and subsisting (particularly if you and your spouse have ever lived apart for any period, or if your ILR was granted some time before this application)
- Your spouse’s proof of British citizenship (passport or naturalisation certificate)
Why Choose Adam Bernard Solicitors for a marriage-based citizenship application?
Marriage-based applications carry a specific risk that generic naturalisation guidance doesn’t cover: the good character assessment includes explicit scrutiny of the genuineness of the marriage itself, and a relationship breakdown or bereavement during the qualifying period changes your position in ways the standard guidance doesn’t spell out clearly. Our immigration solicitors advise on the full pathway — from the initial spouse or partner visa, through Indefinite Leave to Remain, to naturalisation — and can review your case before you commit to the fee.
What if my application is refused?
There is no statutory right of appeal against a refused naturalisation application; your options are reconsideration, a fresh application, or judicial review. See our full guide on the Naturalisation as a British Citizen page for the general refusal process, reconsideration fee (£513) and time limits — the same rules apply whether you applied via the standard 5-year or the 3-year marriage route. If your refusal related to a sham marriage allegation or a good character finding specific to your relationship, tell us this directly, as it changes the strength of a reconsideration request versus Judicial Review.
