In a safe place, keep a list of the items that are stored in your safety deposit box, and tell someone you trust the wherabouts of that list. In times of an emergency, knowing where important papers are stored is vital.
If a person dies suddenly, there will be a need to access important papers stored in the box. Telling someone about the box and its contents will help.
If the death of a loved one is imminent, have that person clear out his/her safe-deposit box.
