How Long Will I Pay or Receive Spousal Support

• The duration of spousal support is thought to be linked to a transition period from married life to single life.
• The duration of support depends on a “rule of thumb.” For marriages that lasted less than ten years, the length of support will equal one half of the time. So for a marriage that lasted 8 years, support will have to be provided for 4 years.
• If you are married for longer than 10 years, the lesser earning spouse will receive alimony for as long as he or she needs to, as long as the other spouse is able to pay.
