Can I Get Social Security for My Granddaughter if I Have Custody?

Yes, you can get Social Security for a grandchild in your custody, but only if specific conditions are met. Legal custody by itself doesn’t qualify her. The Social Security Administration will pay dependent benefits on your record only when your granddaughter’s biological or adoptive parents are deceased or disabled, and when you provide at least half of her financial support. If both conditions apply and you’ve earned enough work credits, she can receive up to 50% of your benefit amount while you’re living, or 75% if you’ve passed away.

The Three Conditions She Has to Meet

Grandchildren face a higher bar than biological or adopted children. The SSA has to be satisfied on three points before it will pay.

Her Parents Must Be Deceased or Disabled

This is the requirement that stops most grandparents. Your granddaughter’s biological or adoptive parents must have been either deceased or disabled at the time you became entitled to retirement or disability benefits, or at the time of your death for a survivor claim.¹ A parent who is alive, not disabled, and simply absent, uninvolved, or incarcerated does not satisfy this rule, even if that parent contributes nothing. The SSA applies its own definition of disability under 20 CFR 404.1501(a), which generally means a severe medical condition expected to last at least 12 months or result in death.

There is one way around this condition: legally adopt your granddaughter. Once she’s your adopted child, she’s treated as your child rather than your grandchild, and the parental-status requirement no longer applies.¹

You Must Provide at Least Half Her Support

You need to be paying at least half of your granddaughter’s ordinary living costs: food, housing, routine medical care, and similar necessities. Contributions can take the form of cash, goods, or services. At the same time, income available to her from any other source, including child support, government assistance, or her parents, must add up to no more than half her living costs.²

The SSA usually reviews the 12 months immediately before you became entitled to benefits. If you started supporting her partway through that period because of a permanent change, such as a parent’s death, the SSA looks at the period from that change forward. If you provided half her support for at least three months and then had to stop for reasons beyond your control, such as your own illness, the SSA can still count that in your favor as long as nobody else has permanently taken over.²

Her Age and Marital Status

Your granddaughter must be unmarried and under 18. Two exceptions extend eligibility past 18:

She is a full-time student at an elementary or secondary school. Benefits continue through the month before she turns 19, or end earlier if she stops attending full time. College doesn’t count.³
She has a disability that began before age 22. Benefits can continue indefinitely as long as the disability persists.³

Marriage at any age ends benefits. The narrow exception: a granddaughter who is 18 or older, disabled, and marries another Social Security beneficiary who is also receiving disability or certain other benefits can keep her payments.⁴

How Much She Can Receive

Your granddaughter isn’t earning her own benefit. She’s drawing from yours as a dependent, and the amount depends on which type of benefit you have.

If You’re Getting Retirement Benefits

She can receive up to 50% of your primary insurance amount, meaning the full benefit you’d receive at your full retirement age.⁵ There’s a ceiling on the total paid on any one record. The family maximum for retirement benefits usually falls between 150% and 180% of your primary insurance amount.⁶ If a spouse and multiple dependents are all drawing on your record, each payment gets reduced so the total stays under the cap.

If You’re Getting Disability Benefits

The rate is the same: up to 50% of your monthly benefit.⁵ The family maximum is tighter, though. It’s calculated as 85% of your average indexed monthly earnings and cannot exceed 150% of your benefit amount.⁷ That leaves less room for multiple dependents to draw full amounts.

If You’ve Passed Away

Your dependent granddaughter can receive 75% of your primary insurance amount as a survivor, higher than the 50% while you’re alive.⁸ The family maximum sits in the same 150% to 180% range as retirement.⁶

Any of these payments assume you have enough work credits on your own record. Retirement benefits generally require 40 credits, about 10 years of work; disability requires fewer, depending on your age.⁹

If the Dependent Route Doesn’t Work: SSI

If you don’t have enough work credits, or you haven’t filed for retirement or disability yourself, your granddaughter may still qualify for Supplemental Security Income. SSI is a separate, needs-based program that doesn’t run through anyone’s work history. It’s for people with very limited income and resources, including children with disabilities.

Grandparents catch a real break here. The SSA “deems” a parent’s income and resources to a child living in the same household, which can disqualify children in higher-income families. This deeming rule applies only to natural or adoptive parents, not to grandparents.¹⁰ If your granddaughter lives with you and you haven’t adopted her, the SSA doesn’t count your income or assets against her. Only her own resources matter.

For 2026, the SSI resource limit for an individual is $2,000, and the maximum federal monthly benefit is $994.¹¹¹² To qualify as a child, your granddaughter must have a medically determinable disability causing marked and severe functional limitations, expected to last at least 12 months.¹³

What to Gather Before You Apply

The SSA needs proof of identity, relationship, and eligibility. Pull these together first:

Social Security numbers for you and your granddaughter
Her original birth certificate
Adoption decree, if you’ve legally adopted her
Court-issued custody or guardianship papers
Death certificates for one or both parents, if applicable
Medical evidence of a parent’s disability, if either parent is alive but disabled
Financial records showing you provide at least half her support: bank statements, rent or mortgage receipts, grocery receipts, utility bills, medical expense records, ideally covering the 12 months before you became entitled to benefits

The SSA reviews originals and returns them. This information goes onto Form SSA-4, the Application for Child’s Insurance Benefits.¹⁴

How to File the Application

Applications for grandchild benefits can’t be completed entirely online. The SSA needs to review original documents and verify the dependency relationship in a way the website portal doesn’t support. That leaves two options: apply by phone, or apply in person at a local Social Security office.

Call 1-800-772-1213, Monday through Friday, 8:00 a.m. to 7:00 p.m. local time, to start the process or schedule an appointment.¹⁵ A representative walks through the application, reviews your documents, and tells you what else is needed. You’ll get a determination by mail.

File early. If your granddaughter was eligible before you filed, the SSA can pay up to six months of retroactive benefits, or up to 12 months if the claim involves disability.¹⁶ Delay costs money. Start the application even if you’re still tracking down some documents.

You’ll Be the Representative Payee

When benefits are approved for a minor, the SSA sends the money to a representative payee rather than to the child. That will be you. The funds come with a legal obligation to spend them on your granddaughter’s needs: housing, food, clothing, medical care, and education. Anything left over must be saved for her.

Misusing a child’s benefits is a federal offense. A representative payee who diverts payments to personal use faces fines, up to five years in prison, or both.¹⁷ The SSA will also revoke your payee status and demand repayment.

Most representative payees have to file an annual accounting report (Form SSA-623 or a related form).¹⁸ If you’re the legal guardian of a minor child and you live in the same household, you’re exempt from that annual reporting requirement.¹⁹ Keep records anyway. Receipts and bank statements protect you if questions arise.

When Payments Will Stop

Certain events end benefits, sometimes with little notice from the SSA. Plan for them:

She turns 18, unless she’s a full-time secondary-school student or has a qualifying disability. Payments end the month before her 18th birthday.
She turns 19 while still in secondary school. Payments end the month before her 19th birthday.
She marries. Marriage at any age ends benefits, with limited exceptions for disabled beneficiaries marrying other Social Security recipients.
Her disability ends, if benefits continued past 18 on that basis. Payments end in the second month after the disability ceases.
An adoption you relied on for eligibility is annulled. Payments end when the annulment takes effect.⁴
