In this digital age, some folks think the safe deposit box to be a relic. But there are documents that need to be the original and are not accepted in pdf form or photocopies, and items that need to be kept offsite.
The documents and items to keep in the safe deposit include: Social Security Card, birth, marriage, and death certificates, paper stock and bond certificates, personal papers, family photos, collectibles, jewelry, flash drive with home inventory for insurance, property records, and car titles.
A few items not to keep there are: durable power of attorney, original copies of your will, health care directives, and anything you may need when the bank is not open like spare keys or a passport.
