It's another inheritance one!
My sibling and I had a verbal agreement that I would take DF's whole estate when he died (as I'm the only one named in his will, sibling isn't as they don't get on, they keep saying he was abusive when they were a child etc. which is stupid as he's pleasant now) and my sibling would take DM's.
DM died earlier this year somewhat unexpectedly and didn't leave any legal will. We then found a draft will naming sibling as taking the bulk of the estate and leaving me a small remainder. This tallies with what DM told me i would be left, as she phoned me up before she died and told me she was trying to 'make it fair' between us.
Initially I told sibling to sort out all the administrative stuff for DM's estate as I was about to have my first DC and was too busy to take it on. Sibling initially was communicative, let me know what was happening. Involved me in the funeral etc.
After a few weeks I told sibling I wanted 50% of mum's estate as per the law since there was no valid will and that i would buy sibling out of their share of the house. Sibling then mostly stopped talking to me, I couldn't find out what was happening with the estate etc. and we argued several times. Sibling was insisting I was doing the wrong thing for pushing for my 50% and they kept mentioning DF's will, which is unreasonable IMO and I find it sad they are talking about this before he's even passed. Sibling wanted to put DM's house up for auction and said they'd be in touch when the estate admin was sorted and would follow the intestacy rules. Then they started selling off assets e.g. the car without consulting me.
I went and got a solicitor to send a letter to my sibling as I wasn't getting any detail about the estate and they were refusing to have me buy out 50% of their share of the house. The solicitor sent a few letters and eventually now sibling has agreed I can buy out their share.
They're now not talking to me though and have refused to see me over Christmas etc. until I 'acknowledge what I've done'. I don't see that I've done anything wrong, I've just pushed for my legal inheritance, and sibling cut contact first. So AIBU?
