Your Missouri last will and testament is a legal document that helps your loved ones and the probate court to know your wishes. You can declare and express what you want to happen to your estate, who would inherit it, who would take care of your minor kids, and how to handle any debts or bills. All these decisions are something you should make for yourself. You cannot leave it up to chance or in some stranger's hands appointed by the state. That's why you should learn more about estate planning's importance and begin the work.

Every U.S. state has varying requirements for a legal last will and testament. If you live in Missouri state, read more about Missouri will laws.

Frequently Asked Questions

Can I decide who would look after my minor children in my will?

Yes, you should name a person as the guardian of your children in your will. It would help avoid any hassles, and they could look after your kids after you pass away.

Should I update my will?

You should regularly check and update your last will after certain life events. It can be a new marriage, a child, or a divorce. Either way, keep updating your will after some time.

What would happen to my estate if I had no immediate family?

If you create a will before you pass away, your estate will go to the beneficiaries you've mentioned. However, if you die without a will, it could go to your extended family or even the state if there are no relatives.

What would happen if someone passes away without a will?

The state's intestacy laws will be followed if someone dies without a will. The interested parties, like the spouse or children, would have to go through a probate process to get their share in the estate.

Can I write down my wishes and consider them a legal will?

Several states do not allow a self-written will unless you've followed the requirements. It would always be better to create a legal will by following all your state rules.
