James J. Burns, CFP® professional and president and founder of JJ Burns & Company says a safe deposit box might be ideal if you’re storing important papers such as contracts or valuable assets like family heirlooms or expensive jewelry. He adds you should never keep cash or a will inside of a safe deposit box. Burns recommends taking time to develop a concrete plan to solidify what you want to store in your safe deposit box, why you want to store it at a bank, and for how long.
