I was digging into the rules for last week's Medicaid and marriage piece when I fell into a different hole entirely. Buried in Social Security’s policy manual is a provision I'd never heard of, and I'm guessing I'm not the only one. It has nothing to do with a wedding and everything to do with what Social Security considers married to be. It’s called holding out, and it means Social Security can treat your adult child as married for Supplemental Security Income (SSI) purposes, even if no license was ever filed and no ceremony ever took place. Crazy right?!
If your child lives with a partner, a roommate, or anyone Social Security could (reasonably or unreasonably in your mind) read as a partner, this is worth twenty minutes of your attention. Not because it’s rare or because Social Security is looking to catch anyone. Rather, the evidence that triggers it is ordinary, easy to create by accident, and may be easier to avoid once you know what it looks like.
What Holding Out Means
Social Security treats someone as married for SSI purposes in three situations.
Your child is legally married.
Your child is married for Title II1 purposes, which covers certain long-term relationships recognized under state law.
Or your child and another unrelated adult are living together and presenting themselves to the community as a married couple, even without a legal marriage.
Title II is the part of the Social Security Act covering disability and retirement benefits for people who've paid into Social Security through their own work, or who qualify as a dependent of someone who has. If Social Security has already decided your child's partner counts as a spouse for one of those programs2, often based on your state's marriage laws, that same married status carries over automatically to SSI, without a separate holding out review.
That third category is holding out, and it’s spelled out in POMS SI 00501.152. Social Security’s own language describes it as leading people in the community to believe the two of you are a married couple. Using words like spouse, husband, or wife to describe each other. Adopting the same last name. The policy specifically notes that terms like partner, girlfriend, or fiancé point the other direction, away from holding out.
How Social Security Checks
This is where it may get uncomfortable. When your child applies for or renews SSI and reports living with another unrelated adult, Social Security asks directly whether they hold themselves out as married. If your child says no and nothing contradicts that, the file gets a note and nothing more happens.
But if either person says yes, or if there’s evidence pointing the other way, a caseworker starts asking harder questions.
What name do you go by?
How do you introduce this person to friends and family?
How does your mail get addressed?
Are there any bills, tax returns, or contracts that list you both as spouses?
Who owns or rents the home you live in?
If those answers raise a flag, the caseworker moves to documents. Mortgages, leases, bank accounts, insurance policies, tax returns, and credit cards carry the most weight. Records from other government programs come next. Then things like magazine labels addressed to both names, or statements from neighbors and relatives who assumed the two were married.
None of this requires your child to have done anything deceptive. A joint checking account was opened for convenience. A landlord who only offered one lease and both names ended up on it. Filing taxes together because a friend said it would save money, without anyone checking whether that was actually true for their situation. Each of these, on its own, is a normal decision two adults sharing a home might make. Stacked together, they can add up to a caseworker deciding the relationship reads as marital.
The reason this matters isn’t abstract. Once Social Security determines two people are holding themselves out as married, it applies deeming rules, meaning both people’s income and resources get counted together when calculating SSI eligibility.3 For a lot of families, that’s enough to shrink the benefit substantially or end it outright. And because Medicaid eligibility is tied to SSI status in many states, a change here can ripple into healthcare and Waiver coverage too, which is exactly the ground the Medicaid and marriage piece walks through in more depth.
Why This Isn’t as Bleak as It Sounds
I want to call your attention to something the policy itself makes clear. Holding out isn’t a trap that springs shut on people who did nothing wrong. It takes real evidence, and it takes both people’s conduct pointing in the same direction. Social Security’s own examples show this plainly.
In one, two roommates split rent with no shared finances, and no development for holding out was needed at all. In another, one partner told Social Security they considered themselves married while the other explicitly said they didn’t, and because only one side presented it that way, no holding out was found.
The pattern underneath all of it is presentation, not private feelings or living arrangements alone. Two people can share a home, share expenses, and love each other without Social Security treating them as married, as long as the way they present that relationship to the world, on paper and in conversation, doesn’t say otherwise.
What to Watch Before It Becomes a Problem
If your adult child is living with someone who isn’t a legal spouse, building a few habits early on goes a long way. Keep finances separate where you can. Be intentional about how leases, tax filings, and mail get set up, and understand what each choice signals before making it. If a caseworker ever asks the direct question about holding out, answer it honestly rather than guessing at what sounds safer.
If your family is navigating a living situation that already involves some of these markers, a work incentives counselor or benefits planner should be able to walk through your specific paperwork before anything gets flagged, not after. That conversation is worth having early. You know about this now. That's the difference between a rule that catches your family off guard and one you saw coming.
