Me and my wife got married here in the UK and then she was successfully granted ILR for 2.5 years. Our relationship started to break down about a year ago, so we decided to take a break and things did not improve. We have been living apart ever since We only just found out a few days ago, that we should have informed the home office of this update, and she has roughly 3 months left on her visa before it expires. As a result of finding out this information we intend to write to the home office straight away to inform them that we have separated and that the visa should be cancelled. my wife is happy with this and understands she will need to leave the country and will do so when instructed by the home office. my question is as we have not realised until now that we need to inform the home office will either of us face any sanctions or punishment?
