My father lives in my home country (Russia) and he would inherit 1/4 of my assets if I die before him, and same in reverse, if he passes away first. He abandoned me and my mom when I was 5 to go into a cult, hasn't helped in any way since and communicated only to ask me to forgive his child support debt.
So far I haven't had much in my name there except a very modest bank account. Unfortunately, my grandma is not doing well and wishes to write me into her will for a country cabin we have.
I told my grandma that because he would automatically get a portion if anything were to happen to me, I do not want anything in my name in my home country, to give it to my mom. She is very offended and thinks she's giving me this big gift.
Another consideration is that I would have to take leave from work without much notice and go and accept the inheritance, which would be mega stressful. My mom is all but retired so shed be fine to go.
