Thanks. Good question. I think I did imagine that this question would be asked.
Basically because I really doubt that I will be using the estate. That I will even be visiting it. Though it should be taken care of. But in any case, I am liable to pay a tax to the state as an owner (as far as I understand), plus some expenses in connection with the estate. And why have the burden of that IF I won't be using the property ? Plus, after all, I am living in the UK - thousands of kms away from where the estate is located. So even if I choose to visit it, I will have to make a number of long journeys before I get there.
Essentially, the issue with this estate emerged after my father passed away in Russia almost 5 years ago. Before me, he was a joint owner with his sister (my now late aunt) - and after my dad died, after the expiry of a certain period from the event of his passing, I became a joint owner with my aunt, by way of inheritance, in 2017.
Later, that same year, my late aunt and her husband initiated discussions with me about them selling HER share (half) of the estate to me. Yes, initially I intended to BUY rather than sell. So I would have become the owner of the FULL estate or dacha. However, in the process of preparing for my purchase of my aunt's share, I changed my mind and intention, and we switched from me buying, to me SELLING my share - alongside my aunt selling HER share (half) simultaneously. Though not to me, obviously.
My aunt, however, passed away in 2020, before managing to sell. So, if I am correct, I am now a co owner with her husband (in my aunt's place) - so again, we each legally own 50 %. Each owns their half. We still haven't carried out the sale though.
