In Louisiana, an interdiction is a court proceeding that appoints a legal representative, called a curator, to handle the personal and financial affairs of an adult who can no longer make sound decisions because of an infirmity. It is the state’s equivalent of what most other jurisdictions call guardianship or conservatorship, and it comes out of Louisiana’s French and Spanish civil law heritage. Courts treat interdiction as a last resort and will only grant it when no less restrictive arrangement can protect the person from harm or exploitation.
Full Interdiction and Limited Interdiction
Louisiana recognizes two levels, and the difference is significant.
Full interdiction applies when someone is consistently unable to make reasoned decisions about both their personal care and their property, or cannot communicate those decisions, and no less restrictive option will protect them.1Louisiana State Legislature. Louisiana Civil Code Art. 389 – Full Interdiction A fully interdicted person loses the legal capacity to enter contracts, manage finances, or make binding decisions about their own care. The curator takes over essentially all decision-making authority.
Limited interdiction applies when someone can handle some parts of daily life but not others. The court must spell out exactly which rights the person loses and which they keep.2Justia. Louisiana Civil Code Art. 390 – Limited Interdiction A person under limited interdiction lacks capacity only for the specific acts the judgment places under the curator’s authority.3Justia. Louisiana Civil Code Art. 395 – Capacity to Make Juridical Acts Someone might keep the right to choose where they live, for example, while losing authority over large financial transactions. Judges evaluate functional ability, not just a medical diagnosis, and are required to limit intervention to what the person actually needs.
What Rights an Interdicted Person Loses
An interdiction judgment carries consequences beyond money management. A person under full interdiction cannot register or vote in Louisiana. Someone under limited interdiction keeps their voting rights unless the judge specifically suspends them. If the person is later moved from full to limited interdiction, their voting eligibility is restored unless the new judgment says otherwise.4Louisiana State Legislature. Louisiana Revised Statutes 18:102 – Ineligible Persons
One detail catches people off guard: the judgment is retroactive to the date the petition was filed, not the date of the hearing. Contracts or legal acts the person entered into after the filing date can potentially be challenged. The clerk of court records a notice of the suit in the parish conveyance and mortgage records as soon as it is filed, and every judgment granting, modifying, or terminating interdiction is recorded there as well.5Justia. Louisiana Code of Civil Procedure Art. 4552 – Recordation of Notice of Suit and Judgment
The Curator and the Undercurator
The curator represents the interdicted person in legal matters and manages their personal care, financial affairs, or both.6Louisiana State Legislature. Louisiana Civil Code Art. 392 – Curators Under limited interdiction, the curator receives only the powers the interdict’s specific needs require. The curator owes a fiduciary duty and must act with reasonable care, diligence, and prudence.
Alongside the curator, the court appoints an undercurator to serve as a watchdog.7Louisiana State Legislature. Louisiana Civil Code Art. 393 – Undercurators The undercurator does not handle day-to-day decisions but monitors the curator and has a duty to alert the court to neglect or exploitation. If a conflict of interest arises between the curator and the interdict, the undercurator steps in to protect the interdict’s position.
A curator who manages the interdict’s estate must post a surety bond before taking office and file annual accountings with the court. A curator responsible for personal care files an annual report describing where the interdict lives and their condition.8Louisiana State Legislature. Louisiana Code of Civil Procedure Art. 4569 – Post-Judgment Monitoring and Reporting Missing these filings is the fastest way to draw scrutiny and risk removal.
Who Can File and What the Petition Needs
Any person can file a petition for interdiction of an adult or emancipated minor.9Louisiana State Legislature. Louisiana Code of Civil Procedure Art. 4541 – Petition for Interdiction You do not have to be a family member. A neighbor, social worker, or friend has the same standing as a spouse or child. The petitioner must verify the petition, swearing under oath that its contents are true.
Medical evidence is the backbone of the case. While the statute sets the legal standard as clear and convincing evidence of incapacity, the practical foundation is a physician or psychologist’s documentation describing the nature of the infirmity and how it impairs decision-making.10Justia. Louisiana Code of Civil Procedure Art. 4548 – Burden of Proof Without a credible professional opinion, the petition is unlikely to survive scrutiny.
The petitioner should also compile an inventory of the proposed interdict’s assets, including real estate, bank accounts, and retirement funds. That inventory shapes the bond the curator will need to post. The petition names the proposed curator and undercurator, with full legal names, addresses, and relationships to the defendant. Petition forms are available through the local Clerk of Court.
Service, Hearing, and Cost
After filing, the petition must be personally served on the defendant. Domiciliary service and long-arm service are not enough. A sheriff’s deputy delivers the papers in person. If the defendant lives in Louisiana but is physically located elsewhere, anyone over eighteen can hand-deliver a certified copy of the petition, citation, and attachments, with service becoming effective once a notarized affidavit confirming delivery is filed. Without proper personal service, the court cannot grant any relief.11Louisiana State Legislature. Louisiana Code of Civil Procedure Art. 4543 – Service Upon Defendant and Notice to Interested Persons
Filing costs vary significantly by parish, from advance deposits of a few hundred dollars to $1,000 or more. Attorney fees add to the total and range widely depending on case complexity.
If the defendant does not already have a lawyer, the court appoints one. The appointed attorney meets with the defendant, investigates the claims in the petition, and reports to the court on whether interdiction appears warranted and whether the proposed curator is suitable. At the hearing, the judge reviews the evidence, hears testimony, and decides whether the petitioner has met the clear-and-convincing-evidence standard.10Justia. Louisiana Code of Civil Procedure Art. 4548 – Burden of Proof If so, the judge signs a judgment that grants the curator authority and defines its scope.
Temporary and Emergency Interdiction
When someone faces immediate danger, waiting months for a full hearing is not realistic. A court can grant a temporary interdiction without advance notice to the defendant and without a hearing if waiting would cause immediate and irreparable harm to the person or their property.12Louisiana State Legislature. Louisiana Code of Civil Procedure Art. 4549 – Temporary and Preliminary Interdiction
To get an emergency order, the petitioner must file an affidavit from a licensed physician or psychologist attesting to facts showing all grounds for temporary interdiction exist; a verified petition or affidavit explaining why waiting would cause immediate and irreparable injury; and a notice affidavit describing efforts to notify the defendant or explaining why notice should not be required.
Once a temporary interdiction is granted, the court must schedule a preliminary hearing within ten days, extendable by one additional ten-day period if the defendant requests it or extraordinary circumstances justify the delay. The court also appoints an attorney for the defendant unless the defendant already has counsel.
Changing or Ending an Interdiction
An interdiction is not necessarily permanent. Anyone, including the interdicted person, can ask the court to modify or terminate the judgment. The court will grant the request if it finds by a preponderance of the evidence that the interdict’s abilities have changed enough to justify a different arrangement, or that the current terms are too broad or too narrow.13Justia. Louisiana Code of Civil Procedure Art. 4554 – Modification or Termination of Interdiction That standard is lower than for the original interdiction, which requires clear and convincing evidence.
The court generally follows the same procedures used for the original petition, so expect a hearing with updated medical evidence and testimony about the person’s current condition. Full interdiction can be stepped down to limited interdiction if the person has recovered some decision-making ability, and limited interdiction can be lifted entirely if full capacity returns.
Less Restrictive Alternatives
Because the law requires courts to order interdiction only when no less restrictive means will protect the person, petitioners should expect judges to ask what else has been considered.
A power of attorney, called a “mandate” in Louisiana law, lets a person voluntarily authorize someone else to handle financial or legal matters. Louisiana mandates are durable by default and remain effective even after the signer loses capacity. The limit is timing: a mandate only works if it was signed while the person still had capacity. Once capacity is gone, the mandate option is gone with it, and interdiction becomes the available path.
Louisiana also recognizes supported decision-making under the Dustin Gary Act.14Louisiana State Legislature. Louisiana Revised Statutes 13:4261.101 – Supported Decisionmaking Agreement Act Instead of transferring decision-making authority, this arrangement lets adults with disabilities choose trusted supporters who help them understand information, weigh options, and communicate their own decisions. The person remains the decision-maker. A supported decision-making agreement can be formalized through a notarized written plan identifying the supporters, the types of decisions covered, and the kind of help the person wants. For many people with intellectual or developmental disabilities, this is enough structure to avoid interdiction entirely.
