The length of a divorce is contingent on four things: each state's mandatory waiting period, whether the divorce is uncontested or contested, how quickly both sides can come to an agreement, and how quickly a judge is able to hear or review the case and sign off. The best-case scenario is an uncontested divorce in a state with a short waiting period which could see a divorce finalized in a matter of weeks. For divorces with highly combative parties, long discovery periods, and other complications, a decision could take months or even years.
