Missouri Last Will and Testament

Home / Last Will and Testament Templates / Missouri Last Will and Testament

A Missouri last will and testament provide directives for how the testator’s estate will be allocated after their death, including financial accounts, personal property, insurance policies, fiduciary assets, and several other properties or assets.

The beneficiaries typically include the testator’s spouse, children, blood relatives, friends, and charities. However, the testator can choose any beneficiary or charitable organization to inherit their property and assets.

Without a last will and testament, the state’s laws determine who will inherit the assets.

It is required for the testator to sign the legal document in front of two competent witnesses and include both witnesses’ signatures to make it valid.

In Missouri, you do not need to notarize, but the testator may have the will’s legality acknowledged by a state-authorized notary. 

If written by an attorney, it can cost about $100 per last will and testament form. You can also use a template or find a free Missouri document. The will template Missouri must be from a legitimate legal or state website.

If you are 18 years or older, you can write your own will in the state of Missouri.

Emancipated minors are also legally permitted to write their own will. However, it still requires the presence and signatures of two witnesses of sound mind 18 years or older to make it a legal document. As long as it meets all of Missouri’s legal requirements, anyone can create their own. That means it may be handwritten if signed in the presence of two witnesses and includes the signatures of both witnesses.
