The only thing that has changed is our address

No new kids, spouses, division of assets, but we live in an another state and like I said, we no longer are in contact the people who were the witnesses. I can’t really imagine needing the witnesses to ever come forward to testify on anything since my family and hubby’s immediate family all know our wishes, but I could see the possibility of my hubby’s aunts, uncles, or cousins challenging our wishes when it comes to guardianship for our kids.
