I'm Doug, and I'm sorry to hear of the confusion. My goal is to provide you with excellent service today.
While it is technically possible for your wife to switch from a survivor benefit based on her deceased former spouse to a spouse benefit based on your earnings, in most instances doing so will not result in more money to her. Let me explain.
Your wife's survivor benefit pays 100% of the benefit that her former spouse was receiving, or eligible for, at the time of his death. But a spouse retirement benefit is capped at just 50% of the amount of money you were eligible for at your full retirement age.
So unless you are still earning at least 200% more in monthly benefits that she is receiving, then she would not benefit by switching to a spouse benefit at this time.
If you predecease your wife, then she will be eligible for a survivor benefit based on your earnings and that should be higher than what she is presently collecting and so she would want to switch benefits in the event you predecease her. But probably not until then.
