When the divorce negotiations start, one of the sticking points is often alimony. Maybe it was addressed in your prenup. If so, good for you. It's one fight that won't have to play out. However, if you and your soon-to-be ex-spouse are miles apart when it comes to agreeing on the amount and duration of alimony payments, you could be in for a longer divorce.
For some exes, it seems very unfair that once the marriage is over, they have to pay at least a portion of the lifestyle choices and daily living costs for their ex-spouses. Even though the divorce is final, sometimes those alimony payments can go on indefinitely.
