A. The signatures must be placed at the end of the will. If

the will consists of several sheets, each sheet must be signed by

the testator or, if the testator is unable to sign, by the person

signing on behalf of the testator or, if there is no such person, by

the authorized person. In addition, each sheet must be numbered.

B. The date of the will must be the date of its signature by

the authorized person. The date must be noted at the end of the

will by the authorized person.

C. The authorized person shall ask the testator whether the

testator wishes to make a declaration concerning the safekeeping of

the will. If so and at the express request of the testator, the

place where the testator intends to have the will kept must be

mentioned in the certificate provided for in Section 6 of this act.

D. A will executed in compliance with Section 4 of this act is

not invalid merely because it does not comply with this section.
