Summary
Section 13 lets a former British citizen resume citizenship after a formal, registered renunciation. A first resumption can be an entitlement where the person has the required UK connection and renounced to acquire or retain the relevant other citizenship. Other resumptions are discretionary.
Eligibility
The applicant must prove that they were British, made a declaration of renunciation that took effect, and now seek British citizenship again. Entitlement also requires the statutory UK connection described in Guide RS1—through the applicant, their father or paternal grandfather, or a spouse or civil partner and that partner's father or paternal grandfather—and that renunciation was necessary to keep or obtain another citizenship. For a pre-1983 renunciation of citizenship of the UK and Colonies, the statute instead refers to keeping or acquiring citizenship of a Commonwealth country. Entitlement is available only once. The Home Office asks for an official statement from the other country, not only a personal explanation.
Where the renunciation was for another reason, or the entitlement was already used once, the Home Secretary may resume citizenship at discretion after considering the reasons and connections. Good character applies. The current adult registration and ceremony cost is £1,670.
What This Route Allows
Registration restores British citizenship. Whether it is by descent follows the statutory resumption rule and the person's former citizenship; it is not automatically upgraded to otherwise than by descent. There is no residence, language, renewal or settlement requirement.
What This Route Is Not
Letting a passport expire, using another passport or acquiring a second nationality does not renounce British citizenship. A formal declaration had to be registered. Section 13 also does not reverse deprivation or a historic loss of a different British nationality status.
An application made from inside the UK does not extend immigration permission. Current RS1 guidance allows travel while the application is pending, but the applicant must use a valid passport and valid immigration status, complete biometrics on time and remain reachable.
Next Steps
- Obtain the registered renunciation declaration and evidence of former British citizenship.
- Prove the qualifying UK connection, present nationality and why renunciation was required.
- Determine whether this is the first entitlement resumption or a discretionary case.
- Apply using Form RS1, address good character and attend a ceremony if approved.
