Yes. Having a disability, physical or intellectual, does not bar anyone from marrying in Utah. Two things do need to be checked before the wedding, and they are the reasons this question gets asked so often. The first is legal: does each person have the capacity to consent to the marriage, and is there a guardianship order that affects it? The second is financial: marriage can reduce or eliminate needs-based disability benefits, and the effect can be severe. Here is how both work.

Capacity to marry

Marriage in Utah is a contract, and like any contract it requires that both parties understand what they are agreeing to. The standard is low. A person needs to understand, at the time of the ceremony, the nature of marriage and the basic obligations it creates. They do not need to understand tax law or property rights. A person with an intellectual disability, a mental illness, dementia, or a brain injury can have the capacity to marry, and most do. The question is individual, not diagnostic.

Utah does not require a capacity evaluation before issuing a marriage license. The issue comes up afterward, usually in one of two ways: a family member seeks to annul the marriage claiming the disabled spouse could not consent, or the marriage is challenged in a later estate or guardianship dispute. Where capacity is in genuine doubt, a letter from the person’s physician or psychologist confirming they understand the decision, obtained before the wedding, prevents most of those fights.

Guardianship

If a person is under a guardianship in Utah, the guardianship order may limit their right to marry, and the guardian’s consent, or the court’s, may be required. Utah courts are directed to tailor guardianships to the person’s actual needs, and many modern orders leave the right to marry intact. Read the order. If it is silent or restricts marriage, the person, the guardian, or the intended spouse can ask the court to authorize the marriage, and courts grant those requests when the person understands the decision. Marrying in violation of a guardianship order invites an annulment petition.

The benefits question, which is usually the real question

This is where couples get hurt, and it is why some couples with disabilities choose not to marry legally.

Supplemental Security Income. SSI is needs-based. When two SSI recipients marry, they are treated as a couple, and the couple’s maximum benefit is roughly a quarter less than two individual benefits combined. When an SSI recipient marries someone who is not on SSI, the spouse’s income and resources are counted, which often reduces the benefit to zero. The resource limit for a couple is only slightly higher than for an individual.

Medicaid. In Utah, most SSI recipients receive Medicaid through SSI, so losing SSI can mean losing Medicaid, including the home and community based waiver services many people with disabilities depend on. Some Utah Medicaid programs count a spouse’s income; some do not. This has to be checked program by program before the wedding.

Social Security Disability Insurance and Disabled Adult Child benefits. SSDI based on your own work record is not affected by marriage. Disabled Adult Child benefits, paid on a parent’s record to an adult disabled before 22, generally end on marriage unless the spouse is also receiving certain Social Security disability benefits. This catches a lot of families by surprise.

Housing and other programs. Section 8, SNAP, and similar programs count household income, so a spouse’s income can reduce or end eligibility.

The right move is a benefits review before the wedding, ideally with a special needs planner or benefits counselor. Sometimes the answer is to marry and absorb a manageable change. Sometimes it is to marry and restructure finances with a special needs trust or an ABLE account so resources do not count. And sometimes the honest answer is that a legal marriage would cost the couple their care, and they choose a commitment ceremony and a cohabitation agreement instead.

If you choose not to marry

Utah does not recognize domestic partnerships, so an unmarried couple has to build the protections marriage would have given them: a cohabitation agreement covering property and expenses, healthcare directives and powers of attorney so each partner can make decisions for the other, and wills or trusts so each inherits. Note that Utah’s unsolemnized marriage process, which can retroactively treat a cohabiting couple as married, ends for new petitions in May 2027, and that couples who hold themselves out as married risk a benefits agency treating them as married anyway. Be consistent.

If you are the parent or guardian

Your adult child’s right to marry is theirs, and Utah law protects it. Your role is to make sure they understand the decision, that the guardianship order is followed if there is one, and that the benefits consequences have been worked out so the marriage does not cost them their care. Blocking a marriage without a legal basis invites a court fight you will likely lose and damages the relationship.
