Louisiana Special Needs Turning 18: What Happens and What to Do Before the Deadline

Everything Changes at Midnight

On your child's 18th birthday, Louisiana civil law presumes them fully competent — regardless of any disability, IQ score, or adaptive functioning level. Every parental right you've exercised for 18 years terminates automatically. No court filing is needed for the transfer itself, and the transfer can occur even if a family has not received a reminder.

This means you can no longer rely on parental status alone to:

• Access their medical records or sign consent forms
• Communicate with their doctors without written authorization
• Manage their bank accounts or government benefits
• Sign their IEP or make educational decisions
• Choose where they live

This isn't a gradual phase-out. It's a hard legal cutoff that applies identically to a teenager with mild ADHD and a young adult with profound intellectual disability. Louisiana law makes no exceptions.

The Two Windows: Before 18 and After 18

The legal options available to your family depend entirely on whether your child has turned 18 yet.

Before 18 (ages 15–17): You can file for continuing tutorship, a streamlined court process that extends parental authority into adulthood. It requires a petition, the parish coroner's written concurrence, and evidence of intellectual or adaptive functioning below two-thirds of average peers. Since 2024's Act 123, you can request a limited continuing tutorship that restricts authority to only the domains where your child needs help. Attorney fees typically range from $500 to $1,500, plus parish filing deposits — dramatically less than adult interdiction. The family does not pay the coroner's evaluation fees.

After 18: The tutorship window closes permanently. Your remaining options are:

• Supported Decision-Making (SDM) — preserves all of your child's rights; requires no court involvement; your child must be able to understand choices with support
• Contract of Mandate (Power of Attorney) — your child must have the cognitive capacity to understand and sign the document
• Interdiction — full adversarial court proceeding; $3,000–$7,000+ in attorney fees plus court and examiner costs; typically takes 3–6 months

What This Looks Like for Specific Disabilities

Autism spectrum: Many adults with autism can participate meaningfully in an SDM agreement. If your child communicates reliably — verbally, through AAC devices, or in writing — SDM combined with a contract of mandate often provides sufficient legal coverage without court involvement.

Down syndrome: Capacity varies widely. Adults with Down syndrome who can understand explained choices typically do well with SDM paired with a mandate. For those with more significant intellectual disability who cannot understand the nature of a contract, filing for continuing tutorship before 18 is critical.

Profound intellectual disability: When your child cannot communicate reasoned decisions with any level of support, continuing tutorship (before 18) or interdiction (after 18) is the appropriate path. Louisiana courts in In re Anderson (2024) confirmed that SDM requires baseline cognitive participation — it's not available when the individual cannot understand the agreement itself.

The Timeline to Follow

12 months before turning 18: Schedule a comprehensive psychological and adaptive functioning evaluation. Request a copy of the most recent school psychoeducational evaluation and IEP from your child's school.

Age 15–17: File for continuing tutorship if your child's functioning qualifies. Contact the coroner's office in your parish of domicile to initiate the concurrence process. Act 123 prohibits the coroner from charging the family for this evaluation.

6 months before turning 18: If your child may have capacity to sign legal documents at 18, work with a Louisiana attorney or notary to draft a Louisiana-specific SDM agreement and contract of mandate. Prepare the documents before the birthday, but execute them once your child is 18 and has the required capacity.

At 18: If you have continuing tutorship, file the certified letters with the school district, medical providers, and banks. If using SDM, provide copies to all relevant institutions. Apply separately to the SSA for Representative Payee status to manage SSI benefits — the federal government doesn't recognize state mandates or tutorship for benefit management.
