What is an Interdiction?
An interdiction is a civil court proceeding asking a judge to determine that an adult lacks sufficient capacity to manage personal or property affairs and to appoint a curator to protect that person and their assets.
The goal is protective — to ensure the person’s health, safety, and property are managed — but it also removes certain legal rights and must be pursued only when less-restrictive alternatives are inadequate.
Types of Interdiction
Limited Interdiction:
Removes only specific capacities (for example, managing money or consenting to medical care). The interdict retains other legal capacities not removed by the judgment. (Louisiana Civil Code Art. 390 and Art. 395)
Full Interdiction:
The person is determined to lack capacity to perform juridical acts, and a curator is given authority over the person’s care and property.
Who Can File a Petition?
Family members, interested persons, and certain public entities can file a petition for interdiction in the civil district court where the person (the “defendant”) lives.
The petition must meet statutory requirements, including:
-
Identifying relatives
-
Stating alleged infirmities
-
Naming a proposed curator
What Does the Petition and Process Look Like?
-
Filing the Petition. The petition is filed in the parish civil district court where the defendant is domiciled. It must include statutory information and may request limited or full interdiction.
-
Court May Appoint an Examiner. The judge often appoints a qualified examiner (medical or other expert) to evaluate the defendant and file a written report before the hearing.
-
Hearing and Rights of the Defendant. Interdiction hearings are summary and afforded preference. The defendant has the right to notice, counsel, present evidence, and confront witnesses. The hearing can be held at the defendant’s location if they cannot attend.
-
Burden of Proof. The petitioner must prove incapacity by clear and convincing evidence. Recent statutory reform clarified that this standard applies in interdiction proceedings.
Emergency/Temporary Interdiction
When immediate danger or substantial likelihood of harm exists, a court can order a temporary or preliminary interdiction (sometimes called a temporary emergency interdiction) to protect the person until a full hearing can be held.
-
Requirements: Emergency affidavits and physician statements are typically required.
-
Duration: Temporary orders are limited in duration and subject to a prompt adversarial hearing.
Less-Restrictive Alternatives the Court Will Consider
Louisiana law and court practice require consideration of less-restrictive options before removing capacity, including:
-
Powers of attorney
-
Representative payees
-
Supported decision-making
-
Targeted limited interdiction
-
Community supports
The court’s examiner report should address whether less-restrictive means are available.
Choosing a Curator (Guardian)
The petitioner often nominates a curator, but the court evaluates suitability, including:
-
Ability to manage finances
-
Avoiding conflicts of interest
-
Filing required reports to the court
Curators have statutory duties, including annual reports and accountings, and they are subject to court supervision.
Typical Timeline & Costs
-
Timeline: Summary preference applies, but a contested proceeding with examiner reports and hearings usually takes weeks to months depending on complexity. Emergency temporary orders may be issued immediately but require quick follow-up hearing.
-
Costs: Court filing fees, attorney fees, costs for examiner evaluations, and ongoing administrative costs (curator bond, reports) vary by parish and case complexity.
Frequently Asked Questions
Q: How long does an interdiction last?
A: An interdiction continues until the court terminates it (for example, if the interdict regains capacity) or the interdict dies. Limited interdictions can be tailored to specific functions and revisited by court order.
Q: Can an interdict still vote or marry?
A: It depends on the judgment. A full interdiction removes juridical capacity broadly, while limited interdiction removes only specified capacities. The specific judgment controls which acts the interdict may still perform.
Q: Are medical opinions required?
A: Courts commonly rely on examiner or medical reports. For emergency petitions, physician affidavits supporting imminent harm are often required.
Q: What if family members disagree?
A: Interdiction is adversarial when contested. The court will hold a hearing allowing parties to present evidence. The petitioner must still meet the clear-and-convincing standard, and the court may appoint counsel for the defendant.

Understanding Louisiana Interdiction: Court-Supervised Protection for Incapacitated Adults
Interdiction is Louisiana’s legal proceeding for the court-supervised protection of an adult who can no longer manage their own affairs due to mental or physical incapacity. It is functionally equivalent to what other states call guardianship or conservatorship. Through an interdiction proceeding, a court appoints a curator — and in some cases a separate undercurator — to manage the personal and financial affairs of the person who has been interdicted. The interdicted person loses some or all of their legal capacity, depending on the type of interdiction ordered, and the curator assumes authority over decisions the person can no longer make for themselves.
Louisiana law recognizes two types of interdiction: full interdiction and limited interdiction. Full interdiction applies when a person lacks the capacity to make any civil acts — financial, medical, or otherwise — and the curator steps into that role comprehensively. Limited interdiction is a more targeted remedy, appropriate when the person retains some capacity but lacks the ability to manage specific types of decisions. A person might be placed under limited interdiction for financial matters only, for example, while retaining the right to make personal decisions about where they live and receive medical care. Louisiana courts are instructed to prefer the least restrictive form of interdiction that adequately protects the person.
A petition for interdiction may be filed by the person’s spouse, any other family member, the person themselves if they anticipate future incapacity, or the state of Louisiana through its appropriate agencies. The petition must be filed in the district court of the parish where the person resides and must allege specific facts establishing the nature and extent of the incapacity. The court will appoint an attorney to represent the person proposed for interdiction, conduct a hearing, and typically require medical or psychological evidence before ordering interdiction. The process is deliberately formal because interdiction is a significant restriction on a person’s civil rights.
Once appointed, the curator has a fiduciary duty to manage the interdicted person’s finances honestly and in the person’s best interest. The curator must typically post a bond, file an inventory of the person’s assets, and provide annual accountings to the court. Depending on the interdiction order, the curator may also have authority to make healthcare decisions, arrange for the person’s housing and care, and manage ongoing financial obligations such as paying bills and managing investments. Every significant transaction may require court approval. The ongoing court supervision that makes interdiction a protective mechanism also makes it an expensive and administratively burdensome one.
Succession is required to transfer a deceased interdicted person’s assets to their heirs — the curator’s legal authority over the interdicted person’s estate ends at death, at which point a separate succession proceeding must be initiated to distribute the property. The interdiction proceeding and the succession proceeding are distinct legal matters. When the interdicted person dies, the curator’s role terminates and the succession representative — executor or administrator — takes over. If the interdicted person left a valid will executed before their incapacity, that will governs the distribution. Louisiana’s intestate succession laws determine who inherits the estate of a person who died under interdiction if that person left no valid will — the same intestate succession rules that apply to any other Louisiana decedent govern the distribution of an interdicted person’s estate.
Alternatives to Interdiction: Planning Tools That Avoid Court-Supervised Management
A durable power of attorney is the most effective tool for avoiding interdiction. In a durable power of attorney, a person — called the principal — designates another person — called the agent or attorney-in-fact — to manage financial and legal affairs on their behalf. The word “durable” is critical: a durable power of attorney remains effective even if the principal later becomes incapacitated. An ordinary power of attorney terminates automatically at incapacity, which is precisely when it is most needed. A properly drafted durable power of attorney, executed while the principal still has full legal capacity, allows the agent to pay bills, manage bank accounts, handle real estate transactions, file tax returns, and conduct other financial business without any court involvement.
A healthcare power of attorney designates someone to make medical decisions on behalf of the principal if the principal becomes unable to make or communicate those decisions independently. In Louisiana, this document may be called a healthcare proxy or may be incorporated into a broader mandate document. The designated agent can communicate with physicians, authorize treatments, and make end-of-life decisions to the extent the principal’s document grants that authority. Unlike interdiction, which gives the curator comprehensive authority imposed by a court, the healthcare power of attorney gives the agent exactly the authority the principal chose to grant — no more and no less.
A living will — also called an advance directive or declaration — allows a person to state their own healthcare wishes in writing while they have full capacity. Rather than delegating the decision to an agent, the living will speaks directly to physicians and healthcare providers about what the person wants if they are in a terminal condition, permanently unconscious, or in an end-stage medical condition and cannot communicate. Louisiana has a specific statutory form for advance directives. Having a living will in place alongside a healthcare power of attorney ensures that a person’s own preferences govern their end-of-life care, regardless of whether family members might disagree.
Louisiana community property rules affect interdiction proceedings when the incapacitated person is married — the curator’s authority over finances extends only to the interdicted person’s separate property and their undivided interest in community property, while the other spouse retains full authority over their own half of community property. This distinction matters practically. The curator cannot unilaterally sell community property without the other spouse’s concurrence or court approval. The other spouse’s financial independence over their own separate property and their share of community property remains intact. This division of authority can create coordination challenges when the interdicted person’s assets and the marital community are intertwined, making careful legal counsel essential in any interdiction proceeding involving a married person.
The proactive planning tools — durable power of attorney, healthcare power of attorney, and living will — work best when they are executed well before incapacity arrives. Once a person lacks the legal capacity to execute a power of attorney, the window for avoiding interdiction is closed. Interdiction becomes necessary when no valid power of attorney exists at the time of incapacity, when the existing power of attorney is legally defective or too narrow to cover the person’s needs, when financial institutions refuse to honor an older power of attorney, or when family members contest the agent’s authority. In all of these situations, the only remedy is a court proceeding. The clear advantage of advance planning is that it keeps the family out of court during an already difficult time.
How Interdiction Interacts With Succession and Estate Planning
One of the most critical intersections between interdiction and estate planning is the loss of testamentary capacity. A person who has been placed under full interdiction lacks the legal capacity to execute a valid will. Louisiana law requires that a testator have testamentary capacity at the time the will is signed — meaning the person must understand the nature of a will, know what property they own, and recognize who their natural heirs are. A person under full interdiction is presumed to lack this capacity. If a will is executed after interdiction is ordered, it is subject to challenge and may be nullified. This is why estate planning documents must be completed while the person still has capacity — waiting until incapacity arrives means the will may never get written at all.
When an interdicted person is a beneficiary of a succession — meaning they stand to inherit property from a deceased family member — the curator receives that inheritance on their behalf. The curator steps into the interdicted person’s legal shoes for purposes of the succession proceeding: signing heir declarations, accepting or renouncing the succession, and receiving the Judgment of Possession distributions on the interdicted person’s account. The inherited property then becomes part of the interdicted person’s estate, subject to the curator’s ongoing management and court oversight. This intersection of an active interdiction and a concurrent succession proceeding adds administrative complexity to both matters.
A Judgment of Possession must be obtained to transfer assets of a deceased person’s estate to an heir who was under interdiction at the time of death — the curator of the interdicted heir’s estate participates in the succession proceeding on the heir’s behalf. The Judgment of Possession names the heirs and their respective interests. When one of those heirs is interdicted, the judgment will reflect the curator’s role, and the transfer of assets to that heir’s estate will be coordinated through the curator rather than directly to the heir. The recording of the Judgment of Possession in the conveyance records of the appropriate parish is what gives the transfer legal effect — and that requirement applies regardless of whether the heir is under interdiction.
A curator who is managing the affairs of an interdicted person who is also an heir in a pending succession should work closely with the succession attorney to protect the interdicted heir’s interests. This includes verifying that the inventory of the deceased person’s estate is accurate and complete, reviewing the proposed distribution for consistency with the decedent’s will or with Louisiana’s intestate succession laws, and ensuring that the interdicted heir’s proportionate share is correctly calculated and received. If there are disputes among the heirs about the succession — which are not uncommon — the curator has both the authority and the obligation to assert the interdicted heir’s rights aggressively. Passivity in a contested succession can result in the interdicted heir receiving less than they are entitled to under the law.
Careful advance estate planning is the most powerful tool available for preventing both the need for interdiction and the complications interdiction creates during succession. A person who executes a durable power of attorney, healthcare power of attorney, living will, and a properly funded revocable trust while they have full capacity has addressed every major contingency. The durable power of attorney handles financial management during incapacity without court involvement. The healthcare documents address medical decisions. The trust ensures that assets pass at death without a succession proceeding. And the will — backed by a pour-over provision — catches any remaining assets. Families who do this planning early face none of the crises that interdiction and contested successions create. Families who delay often face all of them at once.
