Florence Griffith Joyner was a famous and highly decorated Olympic athlete. She made a will. She told everyone that she made a will. She figured that she had done what she needed to do.
The problem was, she didn’t tell anyone where that will was.
When she died, no one could find the will. It’s entirely possible that it’s still sitting in a lawyer’s office, or that she locked it away in a safety deposit box at a bank she used for nothing else. And in the end, after a years-long fight between her husband and her mother, a third party was appointed as the executor.
It doesn’t matter whether you’ve made a will if your executor and beneficiaries can’t find it.
