Lesson from this story -- don't trust that your spouse / partner / family will remember all of the various assets you own. Don't even count on you remembering all of them! One easy solution is to create a simple one sheet overview of assets, and keep it with your financial papers. Include savings accounts, CDs, bonds, stocks, insurances, etc.
A little leg work now may save your heirs hundreds of thousands of dollars!
