Death. Let's talk about it.
I know...I know. You don't want to.
I get it. I'm right there with you. But, it is inevitable for EVERY SINGLE ONE OF US.
If you have kids, you need to talk about it. You need to have a will and a plan in place for your children. If you don't, do you know the state rules for how your children will be taken care of? Will they go to family members? If so, which ones? Your parents, if they're still alive? If not, sibling(s)? What if there's drama in your family? Then what?
Even if you don't have kids, what about any remaining assets you have. If you want the assets to go to a certain individual or distributed amongst people, where is that written? Is it a legally-binding document? If not, then your wishes may not be carried out the way you want.
Point is, please address it now while you're here and healthy and of sound mind. Take the time. Be uncomfortable. Invest the effort to think about and document what you want to have done upon your death. DO NOT make assumptions. In the end, your "heirs" (those that you want to have some part of you or your estate when you pass) may not get what you intend...and it won't be their fault.
Be open what comes.
