If your wife was born before 1964 she can take SS benefits at 62 and in addition you can get a check for half her benefits until you start taking your SS benefits. Your taking a check on her benefits does not affect your SS benefits.
Learned this from a retirement plan specialist we are working with. Just so happens we can take advantage of it as I am going to wait until 70. She is thrilled. That knowledge alone was worth the price of admission.
How can I find out the details about this? Thanks.
