People think their last will and testament controls where their money goes. It doesn't. Not most of it. Your money goes 3 places when you die. Anything you own jointly is going to go to the survivor, the other person, like a bank account, piece of property.

Most of what you have probably goes in the first 2 categories, which means your will controls the smallest pile. So if you spend all your time making your will and not on checking your beneficiary forms, you plan for the thing. Follow me, I know this stuff.
