The Will you have found is for a married person with minor children from a prior marriage. It provides for the appointment of a personal representative or executor, designation of who will receive your property and other provisions. It also provides for the appointment of a trustee for assets left to the minor children.
This Will must be signed in the presence of two witnesses, not related to you or named in your Will. If your state has adopted a self-proving affidavit statute, a state specific self-proving affidavit is also included and requires the presence of a notary public to sign the Will.
