What are a daughters rights when mum dies

Were I the ailing grieving daughter & I knew which FD had my parents body, I'd show up.

The FD may well be in the employ of my disagreed-with sister, but is also used to meeting a lot of distressed folk & could probably sneak me a quiet few minutes if I was calm, cooperative & seriously not looking to pick any kind of quarrel.

A mate might go ahead & set that up for me if they thought the FD could be cooperative, but if they have a compassionate moment you need to be ready to act on it in seconds & also to have a getaway vehicle sorted. (And destination. Somewhere where an ill woman can have a weep in relative comfort & peace. Oddly, the M&S cafes can be ideal once you've got into them but they're rarely easily accessible. McDs rather less with the comfort & peace but what odds potentially irate sis would go looking there?!.)

Meanwhile, who the executors are & if there's a credible copy of the will would be useful information for later on.
