The beneficiary form was completed indicating that the participant was not married. He named his son as beneficiary. After the participant's death, information surfaced that would indicate that the participant was still married, but probably estranged from his wife. She did sign a waiver after the participant's death. Her signature was not notarized. Something like 6 years have gone by since the participant's death. At some point during these intervening years, the spouse returned to her native country. After all this time, the ER would like to distribute the assets to the son. I'm hoping that there is an exception to the spousal beneficiary rule in cases like this. Any thoughts or guidance you can offer?
