The state of Louisiana does not recognize irreconcilable differences as a valid reason for granting a divorce. Instead, you must have a recognized ground to file for divorce. You have the option of filing a fault divorce or a no-fault divorce. A no-fault divorce means that neither party is at fault for the divorce. There are two grounds for a no-fault divorce and both require you to live apart for six months prior to or after filing a divorce petition. For example, if you live with your spouse when you file for divorce, the court requires you to live separate and apart for six months after filing for divorce to file a no-fault divorce. In addition, if you have children together, the court may require you to live apart for one year prior to granting the divorce.However, there are several at-fault grounds to file for divorce in Louisiana. For example, if your spouse has a felony conviction or committed adultery, you can select one of these grounds for divorce and not have to fulfill the requirement of living separate and apart. If you select an at-fault reason for divorce, you will need to provide evidence to the court that your spouse is guilty of one of these grounds before the court will grant the divorce.
