We really need to make a will...
But yeah, I'd go for equal shares.
My parents want to speak to me and my brother and sister about their wills; no idea why. I imagine they'll give equal shares to us, but there will likely be provision for grandchildren. I have two children, but my brother has none yet and my sister has none and has no intention of having any. There might be some specific provisions for things, like they might give me their piano, because my brother can't play and my sister can but lives in Australia. Who knows. We've all fared reasonably well so I don't think there'll be any ill will with equal shares.
Tangential pain in the bum will story...
My grandma on my mum's side died about ten years ago, leaving just her house in Finland. Looking after a house in Finland isn't easy, due to the snow in winter, and you certainly can't leave it unattended and unheated all that time unless you like shattered pipes and holes in the roof. My mum is one of four children. Of the four:
a) My mum lives in the U.K. and has no real use for the house, though she occasionally travels to Finland so could stay there but likely wouldn't.
b) My uncle hasn't worked in years due to ill health but he lives in the house and can just about look after it, though for how much longer?
c) Aunt number one lives in Finland and she and her children and grandchildren like to use the place as a summer house.
d) Aunt number two lives in the U.K. and has no use for the house, not least because her husband is very ill with Parkinson's and broken vertebrae so can't travel there. They used to own a house in the same town but have sold it due to not being able to get over there.
So we have four people with an equal share in the house. One lives there, one wants it when it's convenient, and two aren't interested. Those who want it can barely afford to clean it and look after it and certainly can't buy the other two out. Those who could afford to look after it don't want it. There were huge rows when this all first came to light and so far as I know it's all still up in the air. My mum lost her rag with everyone expecting her to pay for the upkeep so they could use it. It'll all come to the fore again when my uncle gets too ill to look after it or when he dies.
