You must tell the Home Office if you separate or divorce from your partner and you:
- are sponsoring someone for a visa
- are a dependent on your partner's UK visa
- have a 'family of a settled person' visa as a spouse or partner
- have limited leave in the UK because you're the partner of a British citizen, a 'settled person' or someone who has refugee status or humanitarian protection
