To ask whose responsibility it is. LONG

[helpconfused]

I'm trying to be matter of fact below, I'm not being cold and know I should have done more but my family can hold a grudge...

My Nan fell out with her brother in 1989, hasn't spoken to him since.
Her other brother and sister also don't speak to him.
After the fall out he used to my visit my parents house but as he got older the visits dwindled. My dad (it's his uncle) isn't family orientated so didn't visit him at his home and my mum doesn't drive.
A couple of years ago my mum asked me to take her to his house. He wasn't there and a neighbour told us he was in a home. We found out what home it was and visited that xmas. We have always spoken about going again but never made it back.
This morning my dad had a call from
The home to say his uncle passed away today and he was down as next of kin. He didn't understand why and gave my nans number over.
The home contacted my Nan (in her 80s) and told her that she had to arrange the funeral as surviving relative. They can't afford to pay for one and didn't speak to him for 29 years.
The home also informed my Nan that a girl visited him in the home and had control
Of his finances. We do not know who this girl was. They have no details for this person.

Does anyone have experience of this?
Who is responsible?
My parents were the only ones that were in contact with him from 1989 until around 2014 but they cannot afford to pay for a funeral either.
It's so sad :(
Already causing friction.

I have personal experience of a similar situation.
My father died years ago. He had a widowed sister, who had no children.
She estranged herself from my mother, my sister and me.

Last year I had a call to say she had died in a care home. She had told the care Home that she had no family and no next of kin.
A local solicitor had POA and after my aunt died, used a genealogy company to check there really were no next of kin.

I organised the funeral. I had been fond of her when I was younger and she was my dad’s sister!
As it turned out there was enough in her estate to pay for the funeral, but I would have paid myself if not.

It wasn’t hard to organise, I did it all over the phone. My sister and I went to the funeral and were glad we did. It was just us and four staff from the care Home and the solicitor. We didn’t do the tea and sandwiches after though. Just went home.

Why even have a funeral? A funeral is for the family and friends of the person, and sadly he didn't have any.

No one can be forced to pay for anyone else's funeral. The money for a funeral comes from the deceased persons estate. If there's no money in the estate, then the local authority is obligated to provide a basic funeral. Care homes don't want the bother, unfortunately, so will try to pass to responsibilities onto any relative they can contact.

Thanks all.
Things have progressed today and seems my grandparents have softened slightly. They have been to the home to collect his belongings. Talks are going on about a funeral but still can't agree on who should arrange it.
It is so sad and a horrible situation.
They fell out over comments he made to my Nan when my uncle died at the age of 21. That is why they were estranged, so something that cut deep and lasted all these years.
