Learn about the differences between getting a divorce and a legal separation and why you might choose one over the other. 

Fast facts

This type of court case can give you everything that a divorce does, except for ending the marriage. You’ll stay legally married. Filing for separation instead of divorce may be a good option for you if, for example, your religion keeps you from getting a divorce, but you want the other relief available, such as a parenting planchild support, and property and debt division

If you just want to get divorced, you don’t need to file for legal separation first. 

The process for getting a legal separation is much like divorce and uses many of the same court forms. 

Answer a few questions on Get Family and Safety Forms to get the right forms for your situation.

Here’s how legal separation is different from divorce: 

A legal separation is different from being physically separated. Being physically separated just means that you no longer live together. You don’t need to file for legal separation to live apart. 

It depends on where you’re at in the process. 

  • If your case isn't final (a judge hasn't signed a Legal Separation Order yet): You can file a new summons and petition for divorce and have them delivered to your spouse (served on your spouse). You can file this as an "amended petition" in the same case number as your legal separation case. 

If your spouse said they wanted a divorce in their Response to your legal separation petition, you don't need to file a new summons and petition for divorce. Your spouse's response should be enough to change the case to a divorce. 

Probably not. If you file for legal separation, but your spouse puts in their Response that they want a divorce, the judge will probably grant the divorce. To get a divorce, one spouse only needs to show the marriage is irretrievably broken. This means there’s no hope of you getting back together.

Sort of. 

You can file a Petition to Invalidate Marriage (FL Divorce Form 205) and related forms. In this type of case, you ask the judge to grant you an Invalid Marriage Order. This Order declares that your marriage could not legally exist (was void) from the day it started. The Invalid Marriage Order cancels the marriage and makes it as if it never happened. 

Only a very few cases will fit the legal definition of an invalid marriage. The judge will give you a declaration of invalidity if you can prove at least one of these: 

  • One or both of you were under age 17 when you got married.
  • You were both under age 18 when you married. You didn’t have parental or court approval to get married.
  • One or both of you were already married to someone else when your marriage took place.
  • You’re too closely related by blood (closer than second cousins).
  • One of you couldn’t consent to the marriage, because of mental incapacity or alcohol or drugs.
  • One of you used force or threats (called duress) or fraud to make the other marry you. In this situation, only the spouse who was the victim of the duress or fraud can ask the judge to declare your marriage invalid. Try to talk to a lawyer if you want to file this kind of case, or if you’ve been served with such a petition.
  • You haven’t chosen to keep living together as spouses after turning 18, or becoming able to consent, after the duress stopped, or after you discovered the fraud.
