This is not a bad idea! After having to deal with a couple of estates (and realizing what a total pain the in the rear it can be if not organized) you should do some planning for your heirs otherwise they will wish you were dead! 😉
You should try to tie up all the loose ends you can so that you don’t dump everything onto a poor spouse’s lap, child, or other family member. Remember, wills, trusts, estates, etc. are for the survivors not you! If you truly care about the one’s you love ease their burden in a time that will surely be difficult enough!
