My dad wants to add my children to his Will and is requesting the names a SSN''s. What is required information to add a beneficiary to a Will?

Your dad can make a gift to the children of [your name], without naming your children's names. "I give the sum of $10,000 to each living child of my daughter, [your name]."  He can either do a new will, or a codicil to his existing will. He could also make a gift of money or property to your children as a class, listing their names, or to each one of them individually, specifying their names. It is also common to specify the relationship: "I give the sum of $10,000 to the children of my daughter, [your name], in equal shares." "I give the sum of $2,000 to Jane Doe, my granddaughter. I give the sum of $2,000 to John Doe, my grandson." Social security numbers are not needed to make a gift to grandchildren in a will or codicil, or in a trust or trust amendment. Social security numbers should never be listed in will, codicil, trust, or trust amendment. I hope that helps!
