If you have a prenuptial agreement, you may not need to deal with some of the most frustrating aspects of a divorce, provided that your agreement holds up in court. The act of creating a prenuptial agreement does not protect spouses from surprises in the divorce process, and there are plenty of unexpected obstacles that may pop up before reaching an official divorce decree.
Each prenuptial agreement is different, just as each marriage is different, and if one or both spouses find fault in the agreement, they may choose to challenge it in court. Likewise, even if both spouses agree to the terms of a prenuptial agreement, courts may not approve the agreement's terms if they are illegal or unconscionable.
