AIBU that her ashes can be divided?

[Flowerseverywhere]

My sister has recently died after a long illness. She was 52 and had no husband or kids of her own. It was incredibly sad of course but it wasn’t a shock and so her remaining family had time to come to terms with it before she died. Her remaining family are principally me and our brother (and our families). My sister was the eldest then it’s me in the middle (48) and our brother is 46.
Our sister stated in her will that she wanted to be cremated but did not provide any details about where she wanted her ashes scattered. The Norfolk coast always meant a lot to her, she spent lots of idyllic holidays there, childhood and otherwise and so I think she should be scattered there. Our brother thinks that she should be scattered under a tree in the woods near our childhood home where our parents ashes are also scattered. We are in conflict about this and my solution, which I see as pragmatic, is that half of the ashes are scattered under the tree and the other half in Norfolk. My bother thinks that is not acceptable and that she should be scattered in her entirety, as it were. I see my solution as a practical compromise whereas he thinks I’m heartless and cruel. So AIBU to suggest we divide up my sister’s ashes?

My DP and his DS split and shared their mum's ashes. His half are in an urn in our sitting room and the rest were interned with their grandmother overseas.

My mum and aunt did this with their mums ashes, half in the UK, half abroad.

I've said to dp do not scatter me at all or split them up, I just don't like the thought of it for me, but I understand why it happens. I'm sorry for your loss.

I wouldn’t want my ashes split. Neither would I split the ashes of any of my loved ones. But that’s my personal choice.
I can understand your brother’s view.

I hate the thought of ashes being split.

Thanks, everyone. This is all very helpful. I’ll suggest to my brother that we wait a while then come back to the decision. Thanks for all your input.
