Am I entitled to any portion of my ex husband's retirement benefits?

In North Carolina, you are typically entitled to one half of all retirement accounts that were earned during the marriage. There are some exceptions to this rule, and a Court can always distribute differently than just a straight 50/50 split depending on the circumstances, but the general answer is yes. Keep in mind that just as you would be entitled to a portion of his retirement, he is also entitled to a portion of your retirement.
