The automatic change to SS retirement does not happen until you turn full retirement age, my guess for you is age 67. This is FRA for anyone born 1960 or later. Age 62 is the minimum age both of you must be to claim ex-spouse beneifits. So, you can apply now. I suggest calling SSA now, unless you want it unreduced at age 67. To find out if his is high enough for you to get more money, they (SSA) need to look up his info. Get an appointment to apply.
