Indiana Disability Turning 18: Legal Documents You Need

The Legal Cliff No One Prepares You For

On your child's 18th birthday, every legal authority you've exercised for their entire life vanishes. You can't access their medical records. You can't talk to their doctor. You can't manage their bank account. You can't make decisions about their IEP. Indiana law doesn't care about the diagnosis — at 18, the presumption of full legal capacity applies to everyone.

The good news: you don't have to accept either extreme — total loss of authority or the sledgehammer of plenary guardianship. Indiana law provides a spectrum of legal instruments that let you maintain necessary oversight while preserving your adult child's autonomy. The key is having the right documents planned before and executed on or after the 18th birthday.

The Document Stack, In Priority Order

Think of these instruments as layers. Start with the least restrictive and add only what your child's specific situation requires.

Layer 1: Supported Decision-Making Agreement

What it does: Your adult child retains all legal rights and decision-making authority. They designate you (and potentially other supporters) to help them gather information, weigh options, and communicate decisions to third parties. The supporters advise — they don't decide.

Indiana law: IC § 29-3-14, effective since July 1, 2019. The agreement must be signed by the adult in the presence of a notary public (required since the 2021 amendment). Each named supporter must separately consent in writing.

Capacity needed: Low. The adult must enter the agreement voluntarily and understand the general nature of what they're signing. Critically, IC § 29-3-14-4 states that signing an SDM agreement cannot be used as evidence of incapacity — so this document doesn't undermine your child's legal standing.

Cost: $0 to $50 (notary fee only).

Layer 2: Healthcare Representative Appointment

What it does: Designates a person to make medical decisions if a physician certifies that the patient can't make or communicate their own healthcare choices. Unlike the SDM agreement (which is advisory), this grants actual decision-making authority over medical treatment.

Indiana law: IC § 16-36-7. The appointment must be signed by the declarant before either a notary public or two disinterested adult witnesses. Important: since January 1, 2023, healthcare authority cannot be included in a general power of attorney — it must be a separate document.

Capacity needed: Moderate. The person must understand that they're designating someone to make medical decisions on their behalf.

Cost: $0. The Indiana Department of Health distributes the official planning forms for free.

Layer 3: HIPAA and FERPA Releases

What they do: HIPAA authorization lets you access medical records and talk to healthcare providers. FERPA release lets you access educational records if your child is still in school or attending college. Neither grants decision-making authority — they're information-access documents.

Indiana law: Federal statutes (HIPAA and FERPA) apply nationwide. No court filing needed.

Capacity needed: Low. The adult must understand they're permitting information to be shared with named individuals.

Cost: $0.

Layer 4: Durable Financial Power of Attorney

What it does: Delegates authority over financial transactions — bank accounts, bill payments, investment management, tax filing — to an agent who can act on the adult's behalf. "Durable" means it survives the principal's subsequent incapacity.

Indiana law: IC § 30-5. Must be signed by the principal; Indiana also permits witness-based execution under IC § 30-5-4-1, although notarization is recommended for institutional acceptance. Indiana POAs are durable by default (IC § 30-5-10-3) unless the document says otherwise.

Capacity needed: Moderate to high. The person must be of "sound mind" — they need to understand that they're granting someone else the power to handle their money.

Cost: $0 to $500 depending on whether you self-draft or hire an attorney.

Layer 5: Educational Representative

What it does: Lets a parent continue making special education decisions after the student turns 18, including IEP development, placement decisions, and Case Conference Committee participation.

Indiana law: 511 IAC 7-43-6. Can be initiated up to 60 days before the 18th birthday. If the student is choosing to delegate, they submit a written request. If the student cannot provide informed consent, two qualified professionals must certify in writing that the student lacks the capacity for rational educational decisions.

Capacity needed: Low (if student-initiated) or none (if based on professional certification).

Cost: $0. Administered entirely through the school district.

Layer 6: Representative Payee

What it does: Authorizes someone to receive and manage the adult's Social Security benefits (SSI or SSDI). This is a federal administrative designation — completely independent of anything an Indiana court does.

Important: A state-court guardianship does not give you authority over federal benefits. Even a plenary guardian must apply separately to the Social Security Administration to become the representative payee.

Cost: $0. Applied for through the SSA.

When Guardianship Becomes Necessary

If your adult child cannot understand the concept of delegating authority to another person — they can't sign an SDM agreement, can't execute a power of attorney, can't meaningfully consent to a healthcare representative appointment — then court-ordered guardianship may be necessary for domains not covered by administrative alternatives.

Even then, push for limited guardianship targeting only the domains where the person genuinely needs court-imposed authority. A limited guardian might have authority over medical decisions and financial management while the individual retains the right to choose where they live, who they associate with, and whether they vote.

Plenary guardianship — full authority over the person and/or estate, stripping most civil rights — is the last resort. Indiana courts are required to consider and exhaust less-restrictive alternatives before granting it.

The Timeline

Eight months before the 18th birthday: Begin evaluating which instruments your child can participate in. Start person-centered planning. Attend the school's transition planning meeting where SDM and alternatives must now be discussed.

Sixty days before the 18th birthday: Initiate the educational representative process if needed. Schedule the Physician's Report evaluation if you're pursuing guardianship.

On the 18th birthday: Execute the SDM agreement, healthcare representative appointment, HIPAA release, FERPA release, and power of attorney. File for guardianship if none of the alternatives are sufficient.
