My FIL's name is spelled one way on his birth certificate and a different way on his social security card. When they did their POA and wills prepared it is spelled to match his birth certificate. But everything else he has such as DL, bank accounts is what shows on his SS card. I am their POA as well as their executor and beneficiary. They have added me to their bank accounts already. My question is, once they pass will their will be valid since spelling of names are different? He now has dementia and she has had a stroke but they are both still able to understand most things if we keep it in simple terms.
