A divorce settlement with a special needs child has to do work an ordinary settlement never does: it has to protect the child’s eligibility for Supplemental Security Income and Medicaid, fund care that will likely outlast childhood, and set decision-making rules for medical, educational, and eventually adult-guardianship questions. Get any of those pieces wrong and a well-meaning support order can knock the child off benefits worth far more than the payment itself. The SSI resource limit for an individual is $2,000, and even a modest cash transfer or a poorly named beneficiary can push a child over it.
Why Benefits Eligibility Changes Everything
The Social Security Administration treats child support paid for a child on SSI as unearned income to that child. One-third of each payment is excluded; the remaining two-thirds reduces the child’s SSI dollar-for-dollar after other exclusions.1Social Security Administration. Child Support Payments (POMS SI 00830.420) The 2026 federal SSI benefit tops out at $994 per month, so even a middling support order can wipe the check out.2Social Security Administration. SSI Federal Payment Amounts for 2026 Lose SSI and Medicaid may follow, taking with it the therapies, medications, and specialist care that private insurance often covers poorly.
The fix isn’t to cut support. It’s to route money in ways that don’t count as income to the child. Payments a noncustodial parent makes directly to a third party for something other than food or shelter — a therapy provider, a health insurance carrier — aren’t counted as income to the child at all.1Social Security Administration. Child Support Payments (POMS SI 00830.420) A settlement that directs those payments to providers can deliver more real value to the child than a bigger cash transfer that triggers SSI cuts. Every line of the financial section should be tested against this rule before anyone signs.
Custody Built Around Medical Care
Courts decide custody on the child’s best interests, but a disability adds factors that rarely surface in typical cases: each parent’s familiarity with the condition, ability to manage medical appointments and therapies, proximity to specialists, and willingness to follow treatment plans. A guardian ad litem may be appointed to evaluate both households and represent the child directly.
Joint custody can work, but it needs a parenting plan far more specific than the standard form. Spell out who takes the child to appointments, who manages medications, who communicates with the school, and how the plan gets revisited as the child’s needs shift, without a court hearing every time.
Consider a right of first refusal clause. If the parent on duty needs someone to cover, they offer the time to the other parent before hiring a sitter. Most sitters aren’t trained on feeding tubes, seizure protocols, or behavioral plans; the other parent already is.
Visitation That Fits the Child’s Schedule
A standard every-other-weekend rotation often collapses under a child’s therapy calendar and sensory needs. Build visitation around the child’s existing routines, not the other way around. Ask the child’s therapists and teachers what they see: some children regress after frequent transitions, and longer, less frequent stays serve them better; some need duplicate equipment at both homes to hold onto gains. Where one parent is still learning the daily care routine, supervised visitation early on can build competence without putting the child at risk.
Child Support and Medical Expenses
Courts start with the state child support guidelines and adjust upward for the extra costs a disability generates. Bring documentation: therapy invoices, equipment costs, prescription records, and projections from the child’s medical team about future needs. Expert testimony can be the difference between a support figure that holds and one that fails within a year.
Medical expense allocation deserves its own section of the settlement. Most jurisdictions split uninsured medical costs in some ratio, but for a special needs child, “medical” runs well past copays. It covers speech, occupational, physical, and behavioral therapies; adaptive equipment; home modifications; specialized transportation; and treatments an insurer may label experimental. Define what counts as a shared expense, set a process for adding new costs, and include a dispute mechanism for when the parents disagree on whether something is necessary.
Then decide how each dollar moves. Direct-to-provider payments for non-food, non-shelter expenses protect SSI; a lump sum landing in the custodial parent’s account may not.
Special Needs Trusts
A special needs trust holds assets for the child without those assets counting against the $2,000 SSI resource limit.3Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Federal law recognizes two categories, and the choice matters.
A first-party (self-settled) trust is funded with the child’s own assets: a personal injury recovery, an inheritance, or other funds legally belonging to the child. When the child dies, whatever remains must first reimburse the state for Medicaid paid during the child’s lifetime.4Office of the Law Revision Counsel. 42 US Code 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets The child must also be under 65 when the trust is set up.
A third-party trust is funded by someone other than the child, most often parents or grandparents. This is the type usually created in a divorce, funded through property division or ongoing contributions from one or both parents. It carries no Medicaid payback obligation; remaining assets pass to whoever the trust names.4Office of the Law Revision Counsel. 42 US Code 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets
The settlement should name which parent funds the trust, in what amount, on what schedule, who serves as trustee, and who serves if that trustee cannot. Because income inside the trust may be taxed at trust rates, ongoing management by a qualified trustee or advisor matters.
Life Insurance Named to the Trust, Not the Child
Life insurance is a reliable way to keep the trust funded if a parent dies. Beneficiary designations are where families get this wrong. Naming the child directly sends the money to the child (or, for a minor, to a court-supervised arrangement) and can wipe out benefits. Name the special needs trust as beneficiary, spell that out in the decree, and verify it on the insurer’s own paperwork. The beneficiary form on file with the insurance company overrides whatever the divorce agreement says.
ABLE Accounts
ABLE accounts (Achieving a Better Life Experience) are tax-advantaged savings accounts for people with disabilities. Contributions grow tax-free, and withdrawals for qualified disability expenses — education, housing, transportation, health care, assistive technology — come out tax-free.5Internal Revenue Service. ABLE Accounts – Tax Benefit for People With Disabilities
Starting January 1, 2026, eligibility widened: the disability must have begun before age 46, up from age 26.6ABLE National Resource Center. The ABLE Age Adjustment Act Fact Sheet The 2026 annual contribution limit is $20,000.7ABLE National Resource Center. ABLE Account Contribution Limits for the Calendar Year
The SSA disregards the first $100,000 in an ABLE account for SSI purposes. Only amounts above $100,000 count as a resource, and Medicaid continues without interruption even then.8Social Security Administration. Spotlight on Achieving a Better Life Experience (ABLE) Accounts That makes an ABLE account a natural companion to a special needs trust. The settlement should say whether one or both parents contribute, how the contribution is split, and who manages the account.
Taxes: Who Deducts, Who Claims, Who Pays
Child support is neither deductible to the payer nor taxable to the recipient.9Internal Revenue Service. Alimony, Child Support, Court Awards, Damages Alimony depends on timing. For divorce agreements finalized after December 31, 2018, alimony is neither deductible by the payer nor taxable to the recipient. Agreements executed before that date generally follow the older rules unless the parties later modified the agreement to adopt the new treatment.10Internal Revenue Service. Topic 452, Alimony and Separate Maintenance
The Dependency Claim
Only one parent claims the child in a given tax year. The default rule gives the claim to the custodial parent — the parent with whom the child spent more nights. The custodial parent can release the claim to the other parent by signing IRS Form 8332, for a single year or for multiple future years, and can revoke the release effective no earlier than the tax year after the other parent receives notice.11Internal Revenue Service. Form 8332 (Rev. December 2025)
The claim unlocks real money. The Child Tax Credit is worth up to $2,200 per qualifying child, and depending on income the family may also qualify for the Earned Income Tax Credit.12Internal Revenue Service. Child Tax Credit Other credits tied to the dependency claim include the Child and Dependent Care Credit and education credits.13Internal Revenue Service. Dependents A special needs child usually generates higher deductible medical expenses, so the parent who can use the medical deduction may benefit most from the claim. Decide who takes the child each year, or alternate, based on which arrangement gives the two households the most combined benefit, and put it in the settlement.
Education and Therapy Decision-Making
Federal law guarantees every child with a disability a free appropriate public education under the Individuals with Disabilities Education Act, including an Individualized Education Program with measurable annual goals tailored to the child.14Individuals with Disabilities Education Act. 34 CFR 300.320 – Definition of Individualized Education Program Parents have the right to participate in every meeting and challenge decisions they disagree with.15Office of the Law Revision Counsel. 20 US Code 1400 – Short Title; Findings; Purposes
In a divorce, decide who attends IEP meetings, who has final say on placement, and who pays for private schooling or supplemental services when the public option falls short. Joint legal custody gives both parents equal weight, which can produce deadlock when they disagree on a new school, a new therapy, or a revised IEP. Courts can grant one parent primary decision-making authority over education and therapy when shared decisions aren’t working. Address that possibility in the settlement rather than waiting for the first disagreement to escalate.
Therapy costs run for years and shift as the child grows. The settlement should cover current therapies and set a process for evaluating new ones, including how costs are shared and what happens when the parents disagree on necessity.
What Happens at 18
When the child turns 18, parents lose legal authority to make medical, financial, and educational decisions on the child’s behalf. The law presumes adults can decide for themselves, and a diagnosis alone doesn’t rebut that presumption. If the child cannot manage their own affairs, a parent has to petition for guardianship or conservatorship, which involves a court proceeding, an evaluation, and ongoing court oversight.
The settlement should address who will seek guardianship, how the costs are shared, and whether one or both parents will serve. If only one parent is appointed, define the other parent’s role in decision-making. A power of attorney is an alternative, but only if the child has enough capacity to sign one voluntarily; for children with significant cognitive disabilities, guardianship is usually the only route.
Support After 18
Child support does not always end at 18 when the child has a disability. Most states allow courts to extend child support into adulthood for a child who cannot support themselves because of a physical or mental disability. Courts generally ask whether the adult child can earn enough to meet basic living expenses and whether the disability is why they cannot. In most of these states, the obligation continues as long as the disability prevents self-sufficiency. Some states require that the disability arose before the age of majority; others allow support for disabilities that develop later. A minority of states do not authorize post-majority support for disabled adult children at all.
Because the answer varies so much by jurisdiction, the settlement should say specifically what happens at 18. A vague reference to “child support as required by law” leaves both parents guessing and often forces expensive post-divorce litigation.
Estate Documents and the Letter of Intent
Update the estate plan immediately after the divorce. Wills, beneficiary designations on retirement accounts and life insurance, and any trust documents all need to reflect the new family structure. The most common mistake is leaving an outdated beneficiary form in place; that form overrides the will, and an old designation naming the ex-spouse will send the payout to the ex regardless of what the will says.
Both parents should name a successor guardian in their wills — the person who will care for the child if both parents die or become incapacitated. Have that conversation during the divorce, not after, because the parents’ choices may differ and the court will need clear guidance.
The Letter of Intent
A letter of intent is not a legal document, and it may be the most practically useful thing either parent creates. It’s a detailed written guide for whoever takes over the child’s care: daily routines, medication schedules, dietary needs, sensory preferences, behavioral strategies, communication methods, contact information for doctors, therapists, teachers, and friends. Describe what a good day looks like and what a bad day looks like, what calms the child and what triggers distress. No legal document captures that, and a future caregiver will need it.
Both parents should keep their own copy and update it as routines change. The settlement can require both parents to maintain a current letter and share updates with each other and with the named successor guardian.
