They will say the docs don’t exist.
My sister did this with my father’s will.
She was the executor of the estate and pretended it was lost forcing us other through probate.
All siblings should have a copy of the will.
No, it wasn’t filed with the probate office.
We had to pay to get our money.
You can force people into perjury if you know the docs exist (and where they exist) and they don't produce them. Jus' sayin'...
