Please read: general information only. This guide explains in general terms what changes in California when a son or daughter with a developmental disability turns 18. It is not legal, benefits, or tax advice for any particular person, and it does not create an attorney-client relationship. It does not tell you whether your family needs a conservatorship, and it does not help with forms. Social Security, the Regional Center, or the court decides your case. For your own situation, contact your Regional Center, Social Security, a court self-help center, or legal aid. We can't answer questions about your own case, but the groups under Where to Get Help can.
The Short Answer
At 18, your son or daughter becomes a legal adult, and several systems change at once. For SSI, Social Security stops counting the parents' income and resources and reviews disability under adult rules (SSA: Benefits for Children with Disabilities). California presumes adults with developmental disabilities can make their own decisions (DDS: Conservatorship). Families can look at several kinds of decision support, from a supported decision-making agreement to a court-ordered limited conservatorship. The Regional Center keeps planning services through the IPP.
In Taglish — Sa madaling salita: "Ano ang nagbabago pag 18 na ang anak ko?"
Adult na po siya sa batas. Ang SSI ay buwanang tulong na pera mula sa Social Security para sa may kapansanan na mababa ang kita. Sa SSI, hindi na binibilang ang kita at ari-arian ng magulang. Kung naka-SSI na siya bago mag-18, may "age-18 review" gamit ang adult rules. Ang conservatorship ay kaso sa korte kung saan may ibang tao na binibigyan ng power na magdesisyon para sa kanya. Hindi ito awtomatiko, at may mga alternatibo tulad ng supported decision-making. Ang Regional Center ay nonprofit na ahensya na pinopondohan at binabantayan ng estado (DDS), at nag-aayos ng services para sa may developmental disability. Tuloy pa rin ang IPP (Individual Program Plan, ang plano ng services) sa Regional Center.

1. SSI at 18: The Age-18 Review
- Adult rules apply. At 18, SSA generally counts only your adult child's income and resources (and a spouse's), not yours (SSA: Benefits for Children with Disabilities).
- The review. If your child already gets SSI, SSA must review the medical condition under adult rules. This usually happens in the year that starts on the 18th birthday (SSA: Benefits for Children with Disabilities).
- Denied before because of your income? A child who could not get SSI before 18 because of the parents' income or resources may qualify at 18 (SSA: Benefits for Children with Disabilities).
- Work limit. In 2026, SSA treats earnings over $1,690 a month ($2,830 if blind) as substantial work (SSA: Benefits for Children with Disabilities). For how wages change the SSI amount, see SSI at home: work and other income.
- Living at home can change the amount. See How does SSI work when my adult child lives with us?

2. Check for Disabled Adult Child (DAC) Benefits
Some adults with a disability that began before age 22 can get Social Security on a parent's record. SSA calls this a "child's" benefit. A parent must be getting retirement or disability benefits, or must have died after working enough (SSA: Benefits for Children with Disabilities).
- Your adult child must be unmarried and 18 or older. They do not need a work history (SSA: Who Can Get Disability Benefits).
- SSA says a child on SSI should be checked for DAC at 18 (SSA: Who Can Get Disability Benefits).
- You can't apply online for DAC. Call 1-800-772-1213 for an appointment (SSA: Who Can Get Disability Benefits).

3. Representative Payee
A representative payee is a person or group SSA picks to receive and manage benefits for someone who can't manage them (SSA: Representative Payee FAQ).
- SSA presumes adults can manage their own benefits. The law requires a payee for adults found "legally incompetent," which is SSA's term (SSA: Representative Payee FAQ).
- A power of attorney, an authorized representative, or a joint bank account is not a payee (SSA: Representative Payee FAQ).
- You apply at a Social Security office, usually in person (SSA: Representative Payee FAQ).
- A payee manages SSA money only. It does not let them sign other legal papers (SSA: Representative Payee FAQ).
- Parents who live with their adult child and serve as payee don't file the yearly payee report, but they must keep records (SSA: Representative Payee FAQ).

4. Conservatorship and Its Alternatives
Since January 1, 2023, a conservatorship petition must list the alternatives that were considered and say why they won't work (Leginfo: Probate Code 1821; DDS: Conservatorship). Alternatives named by DDS and the law include:
- Supported decision-making (SDM). Your adult child picks trusted supporters who help them understand choices. Your adult child still makes the decision. The agreement is voluntary, in plain language, and can be ended at any time (Leginfo: Welfare and Institutions Code 21001; DDS: Supported Decision-Making FAQ).
- Power of attorney and advance health care directive (Leginfo: Probate Code 1821). California's Attorney General has an advance care planning page with checklists and information on advance health care directives (California Attorney General: Advance Care Planning).
- Representative payee for Social Security, and an authorized representative for some programs (DDS: Conservatorship).
Some of these, like a power of attorney, need your adult child to be able to understand and sign. Whether that is true is a question for a lawyer, not this guide. If your adult child can understand and sign, they may also be able to sign a form that lets doctors share medical records with you. (Not yet confirmed by an official source. Please check with your adult child's doctor's office or a legal aid office.)
A limited conservatorship is the court process for adults with developmental disabilities. The court gives only the powers that are needed (Leginfo: Probate Code 1801; Leginfo: Probate Code 2351.5). See How does a limited conservatorship work?
In Taglish — Sa madaling salita: "Kailangan ba talaga ng conservatorship?"
Hindi po ito awtomatiko o required pag-18. Kailangang ipakita sa korte kung anong mga alternatibo ang tiningnan ninyo, tulad ng supported decision-making, power of attorney, o rep payee (ang taong pinili ng SSA na humawak ng SSI o Social Security ng anak ninyo), at bakit hindi ito sapat. Nagpapaliwanag lang ang guide na ito. Hindi nito sinasabi kung ano ang dapat ninyong piliin.

5. The Regional Center IPP
The Individual Program Plan (IPP) is the plan you make with the Regional Center for services and supports (DDS: Individual Program Plan). California has 21 regional centers (DDS: Regional Centers).
- The IPP centers on your adult child and includes the family as appropriate. Decisions are made by agreement at the meeting (Leginfo: Welfare and Institutions Code 4646).
- You can ask for a meeting when needs change, such as around age 18 or when school ends (DDS: Individual Program Plan).
- You can ask to hold the meeting remotely (the law says "by remote electronic communications"). If there has been no in-person meeting or visit in the past 12 months, the Regional Center must hold one. The law says this rule is pending the department's review (Leginfo: Welfare and Institutions Code 4646). (Whether it applies now is not yet confirmed by an official source. Please check with your Regional Center.)
- DDS started a standard IPP on January 1, 2025. All IPPs move to it by the end of 2027. DDS also has a "Your Youth's Plan" tool for ages 14 to 22 (DDS: Individual Program Plan).
- You can invite anyone. You can record the meeting if you give 24 hours' notice (DDS: Individual Program Plan).
- If you disagree with the plan, the Regional Center must send written notice of your appeal rights (Leginfo: Welfare and Institutions Code 4646).
- IHSS is listed among the services on the IPP Agreement form (DDS: Individual Program Plan). See our IHSS family caregiver guide.
Important: If the Regional Center reduces, changes, or stops a service, or denies one you asked for, it sends a Notice of Action (NOA). To keep current services the same during an appeal, your appeal must be postmarked or received by DDS within 30 days of getting the NOA and before the change takes effect. All appeals must be filed within 60 days. Clients' Rights Advocates can help: (800) 390-7032 for Northern California, (866) 833-6712 for Southern California (DDS: Appeal Information Packet; DDS: Appeals and Complaints).

6. Getting Help in Tagalog
- The Regional Center must talk with you in your preferred language during IPP planning. It must provide language help (the law calls it "alternative communication services") and give you the IPP and the list of agreed services in that language (Leginfo: Welfare and Institutions Code 4646).
- DDS posts IPP forms in Tagalog (DDS: Individual Program Plan).
- The IHSS application (SOC 295) comes in Tagalog (CDSS: IHSS Program).
- Courts generally provide interpreters at no cost (California Courts: Help at Your Court).
Ask for a human interpreter for meetings and hearings. Automatic translation apps can miss important details.
In Taglish — Sa madaling salita: "Puwede bang Tagalog ang IPP meeting?"
Opo. Ayon sa batas, dapat makipag-usap ang Regional Center sa wikang gusto ninyo, magbigay ng tulong sa wika, at ibigay ang IPP sa wikang iyon. May IPP forms din sa Tagalog. Humingi ng totoong interpreter (tao, hindi app).

7. Respite and Caring for Yourself
Caring for your adult child is a long job, and your health matters too. Signs of caregiver stress include feeling exhausted or overwhelmed, getting angry or impatient easily, trouble sleeping, feeling sad or lonely, and frequent headaches or pain. Caregivers are also less likely to get their own checkups (NIA: Taking Care of Yourself). These are signs you need help, not signs you are failing. Some families worry what relatives will think. Asking for respite is not failing.
- Respite is a short break while someone else safely cares for your adult child. In-home respite is temporary non-medical care and supervision at home. Out-of-home respite happens in a licensed facility (DDS: Support Services).
- No state cap since 2018. The old state limits (90 hours of in-home respite per quarter and 21 days of out-of-home respite for a family) ended on January 1, 2018 (DDS: Repeal of Respite Restrictions).
- How families ask. Ask your service coordinator to add respite to the IPP. Explain how much you need and why. If the Regional Center says no, it must send a Notice of Action, and you can appeal (see the deadlines in Section 5) (DDS: Appeal Information Packet).
- Support for you. For your adult child's care, ask the Regional Center about respite first. The California Department of Aging lists caregiver supports such as training, counseling, support groups, and short breaks (respite care) (California Department of Aging: Caregiver Resources). (Not yet confirmed by an official source. Please check with the California Department of Aging.) Caregiver Resource Centers mainly serve caregivers of adults with conditions like dementia or brain injury. Whether they serve parents of an adult with a developmental disability was not confirmed, so ask your local center. (Not yet confirmed by an official source. Please check with your local Caregiver Resource Center.)
Important: If you are in crisis, call or text 988, any time, day or night. It is free and confidential (988 Suicide & Crisis Lifeline). In an emergency, call 911.
In Taglish — Sa madaling salita: "Pagod na pagod na ako. Normal ba ito?"
Opo, maraming nag-aalaga ang nakakaramdam nito. Ang sobrang pagod, madaling magalit, hirap matulog, lungkot, at madalas na sakit ng ulo ay senyales na kailangan ninyo ng tulong, hindi senyales na nabibigo kayo. Humingi ng respite (pahinga habang may ibang nag-aalaga) sa Regional Center at ipasama ito sa IPP. Kung krisis, tumawag o mag-text sa 988.
Your next step: Ask the Regional Center for an IPP meeting around age 18 or when school ends.
