I've found the grave of my dad's dad and he's buried with his parents.
There was no will as they were all poor so I'm guessing ownership if the plot goes to the next of kin.
My Dad has one elder sibling. Does the plot belong to her? If so, once she passes, does the plot go to my dad or to one of her children? She won't be getting buried in it as she lives at the other end of the country.
There isn't even a grave marker, never mind grave stone so it's obviously been left and nobody is interested in it.
