Thanks for the clarification.
Whoever told you about being eligible to collect a benefit based on being married 10 years was probably getting ahead of themselves a bit---because the 10 year rule applies to people who have been divorced after being married at least 10 years.
As a spouse, you are eligible to make a spouse claim after only 12 months of marriage, and so long as you make the benefit claim before your divorce is final, and so long as your husband is already collecting his own benefit, then you are all set.
However, keep in mind that a spouse benefit is a substitute benefit for your own retirement benefit. You will only get the spouse benefit if it turns out that it provided you more money each month than your own retirement benefit.
And because a spouse benefit, as well as an ex-spouse benefit (the 10 year rule), can be at most 50% of the amount the other spouse is receiving, this benefit may not be of any use to you if you are already collecting more than half of what your husband is collecting.
