Thanks for your patience
I am afraid that you will have a capital gain on the sale on that second property as it remained in your name as well, even if you did not (which you indicate) receive anything from its sale.
Unless the transfers had taken place within the actual tax year in which you seperated - this would always have been the case.
Your ex husband will also have a consideration for capital gains on the sale of the marital home - if it remained in joint names and was sold more than 18 months after he moved out.
But it up to him to establish his side of matters - lets deal with your position with this second rental property
Can you advise
1) how much as it purchased for
2) the month and year of purchase
3) What the legal etc costs to buy were
4) the costs of any capital improvements such as new kitchen etc
5) the date of sale
6) how much sold for
7) The costs to sell (legal and estate agents)
8) The dates it was rented from and to
9) confirm that you declared your share of the rental income to HMRC for the dates relevant at question 8
10) What your annual income is so I can advsie the correct capital gain rate
I can then advise your capital gain position, which ideally would have been dealt with as part of the divorce settlement -
