Adult Guardianship and Conservatorship Petition Requirements in Louisiana

At a glance

Requirements one by one

Proceeding and state terminology

Louisiana calls the ordinary adult proceeding interdiction and calls the appointed decision-maker a curator. Civil Code art. 389 permits full interdiction only when the functional inability reaches decisions about both the person's care and property. Article 390 permits limited interdiction when the inability reaches person, property, or only an aspect of either.

The same petition process is used for full and limited relief. Under C.C.P. art. 4541(A)(4)-(5), a petitioner seeking full interdiction must explain why limited interdiction is inappropriate; a petitioner seeking limited interdiction must identify the capacity to remove and the powers to confer.

Who may file and where

C.C.P. art. 4541(A) begins broadly: "Any person may petition" for interdiction of an adult or emancipated minor. The petition must identify the petitioner's relationship to the adult, but standing is not restricted to a spouse or relative.

Article 4542 uses a three-step parish rule. File where the adult is domiciled; if the adult has no Louisiana domicile, where the adult resides; and if the adult has no Louisiana residence, where the adult is physically present.

What the petition must contain

Article 4541 requires a verified petition and particularized facts. It asks for the parties' identifying and address information, their relationship, the adult's proposed residence, the nature and extent of the alleged infirmities, and why interdiction is necessary. It also requires the spouse and nearest family chain, any legal representative, any signed prior curator designation, and the proposed curator's age, education, domicile, address, and reasons for appointment.

The requested scope must be precise. A full petition explains why limited relief will not work. A limited petition identifies each capacity to be removed and each power requested for the limited curator.

Proof required for appointment

The petitioner bears the burden by clear and convincing evidence under C.C.P. art. 4548. The underlying test is functional. Civil Code arts. 389 and 390 ask whether, because of an infirmity, the adult is unable consistently to make reasoned decisions about personal care or property, or to communicate those decisions.

Full and limited relief differ in reach. Full interdiction requires the statutory inability as to both person and property. Limited interdiction may address one domain or one aspect of a domain. In either case, the adult's interests also must be incapable of protection through less restrictive means.

Alternatives the court must address

Less restrictive means are part of both the substantive standard and the pleading. Civil Code arts. 389 and 390 bar the respective form of interdiction unless the adult's interests cannot be protected by less restrictive means.

C.C.P. art. 4541(A)(11) then requires the petition to describe, with particularity, which alternatives were considered or implemented. If an option was not considered or tried, the petition must explain why. It must also state why less restrictive means are insufficient for this adult's needs.

Notice, service, and hearing timing

The adult must receive personal service of the citation and petition under C.C.P. art. 4543(A). Article 4546 separately requires personal service of the hearing notice in the same manner. The hearing proceeds on "reasonable notice" under the current summary-proceeding rule in art. 2595 rather than a fixed adult-specific day count.

Other named people follow two mailing steps. Within three days after filing, the petitioner must send each a petition copy by certified mail, return receipt requested. At least ten days before the hearing, the petitioner must send each the hearing order by first-class mail.

Counsel and hearing rights

If the adult makes no timely appearance through an attorney, C.C.P. art. 4544 requires the petitioner to seek appointed counsel and requires the court to appoint an attorney. The appointment ends if the adult retains counsel or intelligently and voluntarily waives counsel. Unless excused for good cause, the lawyer must personally visit the adult and, as far as possible, discuss the petition, facts, law, rights, and options.

Article 4547 gives the adult the right to attend, testify, present evidence, cross-examine witnesses, and otherwise participate. The court needs good cause to proceed without the adult and may hold the hearing where the adult is located if courthouse attendance is impossible. The hearing may be closed for good cause. Article 4547 makes interdiction a summary proceeding, and art. 2595(A) says a summary proceeding is tried without a jury.

Medical evidence or court examiner

Louisiana does not make a physician certificate a universal attachment to the ordinary petition. C.C.P. art. 4545 says the court may appoint an examiner with training or experience in the alleged infirmity and may compel an examination.

If appointed, the examiner must deliver the written report to the court, counsel, and unrepresented parties at least seven days before the hearing. The report may address the alleged infirmities, whether interdiction is appropriate, whether a less restrictive intervention is available, and which type of interdiction fits.

Limits on the order

C.C.P. art. 4551 requires the judgment to appoint a curator and ordinarily an undercurator, and to state that the curator's powers begin only upon qualification. For limited interdiction, the order may confer only the powers needed to protect the identified interests and must state that the adult retains every natural-person capacity not expressly limited.

Temporary and preliminary interdiction are separate. Civil Code art. 391 requires a substantial likelihood of interdiction grounds plus imminent substantial harm. Under C.C.P. art. 4549, an ex parte temporary order additionally requires immediate and irreparable injury before a hearing can be held and a preliminary hearing within ten days.

What trips people up

Personal service and family mail do not have the same consequence. Failure to serve the adult personally prevents the court from granting the requested relief. Failure to mail another named person does not invalidate the case, but the petitioner or lawyer may be sanctioned.

Common questions

Does filing the petition immediately transfer decision-making power?

No. C.C.P. art. 4551 requires a judgment appointing the curator and states that the curator's powers begin only after qualification.

Is there a special deadline to appeal an interdiction judgment?

Yes. C.C.P. art. 4555 sets a 30-day appeal period from the applicable art. 2087 date. The judgment is not suspended while the appeal is pending.
