Hi. Me and my partner (unmarried /non civil partneship) have a jointly owned a property which we have rented for the last 6 years. Until now everything has been 50/50, in ownership / profits / tax liability. We would now like to revert to putting the profits (but not ownership share) into my name 100% as per the information on this thread. I would be grateful if you could answer the following: 1. We are registered as joint tenants rather than tenants in common, does this matter? 2. Must the rental proceeds go into a bank account personal to myself (rather than a joint account)? 3. After discovering this thread today, is there any issue with going ahead with this for the previous tax year? Kind regards J
