In the end, not much matters in life other than your family. To safeguard and maximize the distribution of your estate (i.e., those things you own at your death, regardless of size or value) to your family or charities, you will need to spend some time planning for how your estate and your business and personal affairs will be managed if/when you become incapacitated, as well as upon your death.
Fail to plan and it is very likely that a probate attorney will be needed to 'probate' much of your estate. And inevitably, that attorney will be paid a sizeable fee out of your estate before anything is passed to your children or other beneficiaries. What's more, the probate process ties up assets for months, sometimes years, delaying distribution to your children and beneficiaries. It is also a public matter, sometimes amounting to an 'invitation' for people to challenge or otherwise aggravate your wants and wishes. There is simply no reason to allow any of your assets (or your family) to fall subject to probate and the pitfalls that come with it.
And beware, a Last Will & Testament, alone,
is your 'Plan' for probate!
