Confirm you meet residency requirements that will allow Louisiana courts to assert jurisdiction over your divorce. At least one spouse must have resided in Louisiana for at least 12 months prior to the filing of the divorce petition. Although you don't have to prove residency before filing a divorce petition, your case could be thrown out of court if neither spouse is a resident of Louisiana and one spouse brings this fact to the attention of the court.
Seek marriage counseling if your spouse opposes the divorce. Although marriage counseling is not required to obtain a divorce, your spouse may sue you for breach of the Declaration of Intent -- a document both spouses must sign before entering into a covenant marriage -- for failure to take "all reasonable steps" to preserve the marriage. Your participation in marriage counseling must be in good faith -- you cannot protect yourself from a lawsuit by simply "going through the motions."
Identify grounds for dissolution of your marriage. Possible grounds include adultery, imprisonment, a death sentence, abandonment for at least one year, physical or sexual abuse, substance abuse, habitual cruel treatment, living apart for at least two years and living apart for at least one year after a legal separation.
Complete a Louisiana divorce petition. Your petition must list and explain your asserted grounds for the divorce. It may not simply allege grounds for divorce -- it must state specific facts that, if proved, will entitle you to a divorce. It must also address issues such as property division, child custody, child support and alimony. If you and your spouse have reached agreement on these issues, you may sign a marital settlement agreement with your spouse and file it along with your divorce petition. Since the requirements for a divorce petition are quite formal, it is best to seek outside help preparing your petition.
Prepare a summons and a proposed order. A summons is a document that formally notifies your spouse that you have filed a divorce petition and a proposed order is a divorce decree that requires only the judge's signature to enforce it. Both of these forms are standardized and "fill in the blanks" versions can be obtained from some Louisiana courts.
File your divorce petition and accompanying documentation in a Louisiana parish where either spouse resides, along with the appropriate filing fee. The filing fee varies by jurisdiction. A Louisiana state official will deliver a copy of your petition and summons to your spouse.
