How to Choose the Right Legal Authority Option in Louisiana for a Disabled Adult — Without a Lawyer
If you're trying to figure out which legal authority option your family needs in Louisiana — SDM, mandate, continuing tutorship, or interdiction — without paying $350–$500/hour for a disability attorney to sort it out, here's the framework: the right option depends on two things. First, does your adult child have the cognitive capacity to understand and voluntarily participate in a legal agreement? Second, have they already turned 18? Those two questions eliminate most of the confusion, because Louisiana's legal mechanisms sit on a clear spectrum from least restrictive to most restrictive, and each one has specific eligibility requirements that narrow the field quickly.
The Decision Framework
Louisiana offers five legal authority mechanisms, and they aren't interchangeable. Each one has a specific use case, a specific eligibility window, and a specific cost profile. Here's how they stack up:
| Factor | SDM Agreement | Mandate (POA) | Full Continuing Tutorship | Limited Continuing Tutorship | Interdiction (Full or Limited) |
|---|---|---|---|---|---|
| Age requirement | 18+ only | 18+ only | Must file before 18 | Must file before 18 | Adult or emancipated minor |
| Court involvement | None | None | Yes (petition + coroner) | Yes (petition + coroner) | Yes (district court) |
| Individual's capacity required | Must understand and participate | Must be competent to execute | Intellectual or adaptive functioning below 2/3 average | Intellectual or adaptive functioning below 2/3 average | Incapable of reasoned decisions |
| Cost | Notary fee only | $150–$500 attorney drafting | $300–$600 court deposit + testing | $300–$600 court deposit + testing | $3,000–$10,000+ |
| Rights preserved | All | All (revocable) | None (status of minor) | Selected rights preserved | None (full) or selected (limited) |
| Legal authority | La. R.S. 13:4261.101–.302 | La. C.C. arts. 2989–3032 | La. C.C. arts. 354–362 | La. C.C. arts. 354–362 (Act 123) | La. C.C. arts. 389–390; La. C.C.P. arts. 4541 et seq. |
Start With Two Questions
Question 1: Has your child turned 18?
If no, and they're between 15 and 17, continuing tutorship is available. This is the least expensive court-supervised option, and Act 123 of 2024 now allows limited continuing tutorship — meaning you can preserve specific rights rather than reducing their legal status entirely. This window closes permanently on the 18th birthday.
If yes, continuing tutorship is off the table. Your options are the voluntary mechanisms (SDM, mandate) or court-ordered interdiction.
Question 2: Can your child understand and voluntarily participate in a legal agreement?
If yes — even with support — Supported Decision-Making under the Dustin Gary Act is the starting point. The individual retains all legal rights. A supporter helps them gather information and communicate decisions, but never makes decisions for them. It costs nothing beyond a notary fee, requires no court, and satisfies the legal preference established by the Dustin Gary Act (courts must now confirm that less restrictive alternatives were considered before granting any interdiction).
If your child can understand some agreements but not others — they can handle healthcare decisions with support but can't manage finances — a mandate (Louisiana's term for power of attorney) can cover the specific areas where they need representation while SDM covers the rest. Mandates require the principal to be competent at the time of execution.
If no — your child cannot understand the nature of these agreements and requires constant supervision — interdiction is likely necessary. The Third Circuit Court of Appeal confirmed in In re Anderson (2024) that when an individual lacks the baseline cognitive capacity to understand and participate in an SDM agreement, the court may order interdiction despite the statutory preference for less restrictive alternatives.
The Hybrid Approach Most Families Miss
Most families think of these options as mutually exclusive — you either get SDM or you get interdiction. In practice, many Louisiana families benefit from layering multiple mechanisms:
SDM + Healthcare Mandate + HIPAA Authorization: For an adult who can make daily decisions with support but needs someone authorized to communicate with doctors and access medical records. The SDM agreement covers daily decision-making, the healthcare mandate covers medical authority, and the HIPAA authorization ensures providers actually share information (some providers are skeptical of SDM agreements alone).
Limited Interdiction + Representative Payee: For an adult who can manage personal decisions but genuinely cannot handle finances. Limited interdiction under La. C.C. art. 390 covers state-level financial authority while a free Representative Payee designation through the SSA covers federal benefits management — the two systems don't automatically recognize each other.
SDM + Representative Payee (No Court at All): For an adult who functions well with support in most areas but needs help managing SSI payments. The SDM agreement is voluntary, and the Representative Payee designation is a free SSA administrative process. No court involvement, no attorney fees, and no annual judicial accountings.

Who This Is For
- Parents approaching their child's 18th birthday who need to choose between continuing tutorship, SDM, mandate, and interdiction — and don't want to pay $350–$500/hour for an attorney to explain the options
- Families who have been told "you need guardianship" (wrong term in Louisiana) and want to understand the full spectrum before committing to the most restrictive option
- Parents whose child falls in the middle — capable of some decisions but not others — and need to understand the hybrid approach
- Families in rural parishes where disability attorneys have 3-6 month waitlists and the 18th birthday deadline is approaching
Who This Is NOT For
- Families dealing with contested custody or family disagreements about who should serve as tutor or curator — those situations require legal representation
- Parents whose child has significant assets (inheritance, structured settlement, trust distributions) that require professional estate planning advice
- Anyone facing an emergency situation where the individual is in immediate danger — emergency interdiction under La. C.C.P. art. 4549 is time-critical; petitioner representation is not legally required, but an attorney is strongly recommended from day one
Tradeoffs
Choosing without a lawyer means you're responsible for accurately assessing your child's capabilities and matching them to the right legal mechanism. The risk isn't choosing the wrong option — it's choosing a more restrictive option than necessary because a more restrictive option feels safer. Louisiana law now actively pushes against this tendency: the Dustin Gary Act requires interdiction petitioners to prove that less restrictive alternatives were considered and found insufficient.
The Legal Authority Blueprint mitigates this risk by walking you through a structured capacity assessment before presenting the legal options. You evaluate your child's abilities across specific domains (healthcare, finances, housing, education, daily living) before deciding which mechanisms to pursue, rather than starting with a legal category and fitting your child into it.
Frequently Asked Questions
What if I'm not sure whether my child can understand an SDM agreement?
This is common, and it's exactly the situation where a capacity assessment helps. The Legal Authority Blueprint includes a domain-by-domain assessment worksheet. If your child can understand the concept of "this person helps me make decisions about money" but not "this person helps me make decisions about medical treatment," that suggests SDM for finances with support, while medical authority should be handled through the statutory surrogate-consent hierarchy in La. R.S. 40:1159.4 or through a court-supervised mechanism if broader authority is needed. The goal is to preserve as much autonomy as possible while providing genuine protection where it's needed.
Can I start with SDM and switch to interdiction later if it doesn't work?
Yes. SDM and mandates are voluntary and can be revoked. If you try SDM and find that your child genuinely cannot participate meaningfully — providers refuse to honor the agreement, or the individual is making decisions that put them in danger — you can file for interdiction at any time. Starting with SDM also strengthens an interdiction petition, because you can demonstrate to the court that you tried the less restrictive alternative and it was insufficient.
Do Louisiana courts prefer limited interdiction over full interdiction now?
The trend is clearly toward limited interdiction. The Dustin Gary Act requires petitioners to demonstrate that less restrictive alternatives were considered, and courts are interpreting this as a preference for limiting interdiction to only the specific capacities where it's necessary. Full interdiction — which strips all civil rights — is increasingly reserved for individuals who genuinely cannot make or communicate any reasoned decisions. The distinction matters: full interdiction is sometimes called "civil death" by Louisiana appellate courts.
How do I handle medical authority specifically?
Medical authority is one of the most common reasons families seek legal mechanisms. In Louisiana, a healthcare mandate under the Civil Code's contract-of-mandate rules (La. C.C. arts. 2989–3032) can designate an agent to make healthcare decisions, and a HIPAA authorization allows access to medical records. These can be executed as standalone documents — you don't need interdiction or tutorship just for medical authority. The catch is that the individual must be competent to execute these documents, which means they need to understand what authority they're granting.
What if my child is 17 — should I file continuing tutorship now or wait to see if SDM works after 18?
If there's any possibility your child will need court-supervised protection, file continuing tutorship now. You can always petition to terminate it later if SDM proves sufficient, but you cannot retroactively file continuing tutorship after the 18th birthday. The window is permanent and non-negotiable. Filing a continuing tutorship petition doesn't prevent you from also setting up SDM and mandates — the mechanisms can coexist.
