Family law covers the paperwork that shapes divorce, custody, child support, adoption, guardianship, and other family matters. These filings are emotional and high-stakes, and they also have to meet strict procedural rules for service, financial disclosure, and parenting plans. Clean, accurate paperwork keeps the focus on getting a workable outcome for the family instead of getting derailed by technical problems that delay hearings or force amended filings.

Checked against the law it cites

A reviewer verified this template's legal citations against the official source on August 23, 2026.

La. R.S. 9:311(A)(1), (C)(1), (C)(3)(a)(i) (checked August 23, 2026): "An award for support shall not be modified unless the party seeking the modification shows a material change in circumstances of one of the parties between the time of the previous award and the time of the rule for modification of the award. The material change in circumstances must be substantial and continuing since the last award for support. For purposes of this Section, in cases where the Department of Children and Family Services is providing support enforcement services, there shall be a rebuttable presumption that a material change in circumstances exists when a strict application of the child support guidelines would result in at least a twenty-five percent change in the existing child support award. If appropriate, the court may modify the amount of the existing child support award every three years if the existing award differs from the amount which would otherwise be awarded under the application of the child support guidelines."

La. C.C.P. art. 74.2(C) (checked August 23, 2026): "A proceeding for modification of support may be brought in any of the following: The parish where the person awarded support is domiciled if the award has been registered in that parish pursuant to the provisions of Article 2785 et seq.; the parish where the support award was rendered if it has not been registered and confirmed in another court of this state; the parish where the support award was last registered if registered in multiple courts of this state; or, if the person awarded support is no longer domiciled in the state, the parish where the other person is domiciled, the parish where the support award was rendered if not confirmed in another court of this state, or the parish where the support order was last confirmed."

La. R.S. 9:315.1(A)-(B) (checked August 23, 2026): "There shall be a rebuttable presumption that the amount of child support obtained by use of the guidelines set forth in this Part is the proper amount of child support. The court shall give specific oral or written reasons for the deviation, including a finding as to the amount of support that would have been required under a mechanical application of the guidelines and the particular facts and circumstances that warranted a deviation from the guidelines."

La. R.S. 9:315.20 (checked August 23, 2026): "Obligation Worksheet A (The worksheet for calculation of the total support obligation under R.S. 9:315.8 and 315.10). Obligation Worksheet B (The worksheet for calculation of the total child support obligation under R.S. 9:315.9)."
