My first husband turns 62 on December 17th of this year (2017). My second husband (who will get far more than my first for social security) won't turn 62 until 2021. First marriage lasted 23 years, second lasted 13. I am 60. I had planned to start collecting on my second husbands SS in 2024 when I am 67 years old. Would I be able to start collecting on my first husbands SS next month and change it to my second husbands in 2024?
