I don' think so as the insurance companies would have probably asked for documentation before writing large checks.Did he get payouts because he claimed she fell at different properties he owned that were insured with different insurance companies?
Instead, I think he had multiple high dollar insurance policies from different companies. In the end, he had been in the "sue'em game" his entire life and his family had been in it for generations.
I am thinking that he kept multiple polices as, well, "insurance" in the event that the tables were ever turned on him one day and he was targeted by a lawsuit.
Then again, the multiple high dollar policies may reflect something far more sinister than just extra insurance against lawsuits.
