Hi Larry iam 58 can I file for my ex husband retirement he's remarriage now

Hi. No. The earliest that you can potentially qualify for divorced spousal benefits on the account of a living ex-spouse is at age 62, and if you start drawing divorced spousal benefits prior to full retirement age (FRA) your benefit rate will be reduced for age. The requirements for divorced spousal benefits are outlined in the following section of Social Security's handbook: https://www.ssa.gov/OP_Home/handbook/handbook.03/handbook-0311.html.

Best, Jerry
