MyIn 1994, my father received a three-room apartment in Chita for four people: he,mother , me andbrother . Father died. Recently my brother got his two two-room apartments for himself and his family, I also recently got a two-room apartment at work.

My mother wanted to move closer to us and sold her three-room apartment to buy an apartment with this money.money . My brother offered me one of his two-room apartments. She gave him all the money and settled in a two-room apartment that was not privatized. Then my brother privatized the apartment. They wanted to register a deed of gift to my mother, but for some reason someone allegedly said that they had to wait 5 years for this (I consulted with Rosreestr, there is no such law).

My brother invested all the millions given to him by his mother into a mortgage for a future three-room apartment. Three years have passed. Now my mother is very ill. No one even mentions a deed of gift. Everyone is happy with everything. We live quietly and peacefully. But in the long term, I have no inheritance at all. What should I do?
