Amendment History
Amended by Acts 1961, No. 23, §1; Acts 2000, 1st Ex. Sess., No. 25, §3, eff. 7/1/2001; Acts 2003, No. 1008, §2.
Plain-English Summary
Article 4548 is short, but it sets the tone for the entire hearing: the petitioner carries the burden of proving interdiction is warranted, and clear and convincing evidence is the standard that proof must meet. That sits above the preponderance-of-the-evidence standard used in most civil cases, though below the beyond-a-reasonable-doubt standard reserved for criminal cases.
The heightened standard is deliberate. Interdiction removes a legally competent adult's authority to manage their own person and property, so the law demands more than a bare tip of the scales before a court takes that step. The petitioner's evidence has to leave the court with a firm belief, not just a slight edge, that interdiction -- and, where relevant, the specific scope of interdiction requested -- is justified.
This standard works alongside the other safeguards built into Title VIII: the examiner's report Article 4545 authorizes, the least-restrictive-means showing Article 4541 requires in the petition, and the participatory rights Article 4547 gives the defendant at the hearing all feed into whether the petitioner has met this clear-and-convincing bar.
