If you are over the age of 18 and of sound mind, you are legally entitled to make a will in Kansas. You can also make a will if you are under 18 but “emancipated” by marriage.
There are some legal requirements to make a will valid. It must be in writing and:
Signed by the person making the will or by a representative of this person
Signed by two or more competent witnesses present at the signing of the will
