How to Prepare for SSI Age-18 Redetermination Without a Lawyer

You Can Handle This Yourself — Here's How

The SSI age-18 redetermination is an administrative review, not a legal proceeding. SSA sends your family a packet, you gather evidence, and you submit it. No attorney is required at this stage, and the majority of families navigate it successfully without legal representation. The key is understanding exactly what the adult standard evaluates and submitting evidence that speaks directly to those criteria.

Where legal help becomes genuinely necessary is if you're denied and need to escalate past the first reconsideration — but even then, you have a structured appeals process with built-in protections. Here's the full preparation roadmap.

Understanding the Adult Standard

The childhood SSI standard asks whether your child's disability causes "marked and severe functional limitations." The adult standard is different — it evaluates the adult disability criteria, including whether your child can engage in Substantial Gainful Activity (SGA). The 2026 SGA amount for non-blind individuals is $1,690 per month.

This isn't just a clinical question. For adult disability claims, SSA describes this evaluation as a five-step sequential process:

1. Is the person currently working above SGA? For a new adult claim, work above SGA can preclude disability eligibility. In an age-18 redetermination, earnings above SGA do not automatically end SSI; SSA still evaluates the adult disability criteria.
2. Is the impairment severe? The bar here is low — it must cause more than a minimal limitation in basic work activities.
3. Does the impairment meet or equal a listed condition? SSA maintains a Listing of Impairments (the "Blue Book"). If your child's condition meets a listing, approval is automatic without further analysis.
4. Can the person do their previous work? For most 18-year-olds, this step is moot — they have little or no work history.
5. Can the person do any work in the national economy? This is where most contested redeterminations are decided. SSA considers age, education, and residual functional capacity.

The practical implication: your evidence package should demonstrate either that your child meets a Blue Book listing (step 3) or that their functional limitations prevent any sustained employment (step 5). Evidence that focuses only on diagnosis — "my child has autism" — isn't sufficient. You need documentation of how the condition limits specific functional capacities.

The Evidence Package

Start gathering these documents three to six months before your child's 18th birthday:

Medical records — Recent treatment notes, medication lists, and specialist evaluations. The most useful notes describe current functional limitations. If your child hasn't seen their primary care provider or specialist recently, schedule an appointment specifically to document those limitations. Notes that say "condition stable, continue current medications" are less useful than notes that describe what your child cannot do independently.

Psychological or neuropsychological testing — If your child has an intellectual disability or autism spectrum diagnosis, recent cognitive and adaptive behavior assessments are critical. Adaptive behavior scales (Vineland, ABAS) directly map to SSA's functional-capacity criteria. Testing that is no longer current may be questioned — ask whether updated testing is warranted.

School records — The most recent IEP is a gold mine of functional-limitation documentation, particularly the Present Levels of Academic Achievement and Functional Performance (PLAAFP) section. Transition assessments, functional behavior assessments, and teacher reports all provide third-party evidence of limitations. Request these from the school district before your child exits — once they graduate or age out, getting copies becomes harder.

Employment-related evidence — If your child has had a job (including supported or sheltered employment), document the accommodations required. A job coach's notes showing that your child needed one-on-one supervision, modified tasks, or reduced hours are powerful evidence that unsupported SGA isn't feasible.

Daily living documentation — SSA's Adult Function Report (Form SSA-3373) asks about daily activities, social functioning, and the ability to handle changes in routine. Fill this out with specificity: not "needs help with meals" but "cannot use the stove unsupervised, cannot plan or shop for groceries independently, and needs verbal prompting to eat on schedule."

The Timeline

SSA initiates the redetermination around your child's 18th birthday, but the exact timing varies. You don't control when the packet arrives — you control how prepared you are when it does.

6 months before turning 18: Begin gathering medical records, scheduling updated evaluations, and requesting school records. Ask your child's school to include transition assessment data in the most recent IEP.

When the packet arrives: You typically have 30 days to respond with the initial questionnaire. If you need more time to gather evidence, call your local SSA office immediately and request an extension.

After submission: SSA forwards the case to Delaware's Disability Determination Services (DDS), which reviews the medical evidence and may schedule a consultative examination. These exams are conducted by SSA-contracted providers, not your child's own doctors. If a consultative exam is scheduled, attend it; if you cannot, contact DDS promptly to explain and reschedule.

If You're Denied: The Appeals Ladder

Roughly one-third of childhood SSI recipients lose benefits at the age-18 redetermination. If your child is denied, you have four levels of appeal:

1. Request for Reconsideration (60 days to file) — This is the step you should absolutely handle yourself. File within 60 days of the denial notice. If you want payments to continue during review, request benefit continuation within 10 days of receiving the notice.

The reconsideration is an independent review of the determination. Submit any additional evidence you've gathered since the initial filing — new medical records, updated testing, a more detailed function report.

2. ALJ Hearing — If the reconsideration is also denied, you can request a hearing before an Administrative Law Judge. This is the stage where hiring an attorney or representative becomes genuinely worthwhile. You'll testify about your child's functional limitations, and the ALJ may question a vocational expert. Many attorneys and representatives work on contingency for SSI cases (they're paid from back-benefits if you win, with fees subject to SSA approval and capped at the lesser of 25% of past-due benefits or $9,200).

3. Appeals Council Review — A paper review of the ALJ decision. Rarely overturns findings of fact, but can remand for procedural errors.

4. Federal Court — Filing in U.S. District Court. This is uncommon; people often seek an attorney or legal-aid help at this stage.

The critical point: the first-level reconsideration is designed for self-representation. The ALJ hearing is where professional help makes a meaningful difference.

What Most Families Miss

The financial rules change in your favor. At 18, SSA stops counting parental income and assets. If your family was previously denied SSI because of household income, your adult child may now qualify based solely on their own (likely minimal) income and assets. The $2,000 resource limit applies only to the individual — not the household.

Medicaid doesn't depend on SSI. If SSI is denied, your child doesn't automatically lose Medicaid in Delaware. The CCADP (Katie Beckett pathway) evaluates only your child's personal income and assets. A separate Medicaid application through DMMA is worth filing regardless of the SSI outcome.

Continue benefits during appeal. If you file the Request for Reconsideration within 10 days of the denial notice and request continued payment, your child keeps receiving SSI and Medicaid while the appeal is pending. If the appeal fails, you may owe an overpayment — but the continuity of benefits during review is usually worth the risk, especially for Medicaid coverage.

Who This Is For

• Parents preparing for the SSI age-18 redetermination who want to handle the evidence gathering and initial filing themselves
• Families who were denied childhood SSI due to parental income and want to re-evaluate under the adult financial rules
• Parents who received a denial and want to understand whether the first-level reconsideration is something they can manage without an attorney

Who This Is NOT For

• Families whose child has already been denied at reconsideration and needs ALJ hearing representation
• Parents seeking someone to handle the entire process on their behalf
• Situations involving concurrent guardianship proceedings or special needs trust complications

Frequently Asked Questions

How long does the SSI age-18 redetermination take?

The timing varies by caseload and by the stage of review. An initial review, reconsideration, and ALJ hearing can each add substantial time, with hearings often taking longer than earlier stages.

Can I submit evidence after the initial packet is filed?

Yes. You can submit additional medical records, testing, and documentation during the review process, subject to any deadline SSA gives you. If you receive new evidence after filing — updated assessments, a new specialist evaluation — send it directly to your local SSA office with your child's Social Security number referenced.

What if my child is working part-time?

Working doesn't automatically disqualify your child. During an age-18 redetermination, earnings above SGA do not automatically end SSI, but wages can reduce the SSI payment under SSI income rules. If your child earns above SGA but only with substantial support (a job coach, modified duties, employer accommodations), SSA considers that information — but document the supports thoroughly.

Should I hire a disability advocate instead of an attorney?

Non-attorney representatives (often called disability advocates or claim representatives) can represent you in SSA's administrative appeals, but not in federal court, and are often less expensive than attorneys. They must be registered with SSA. For the initial redetermination and reconsideration, self-preparation is usually sufficient. For an ALJ hearing, either a registered representative or an attorney adds meaningful value.
