Domestic partnership in Kentucky has no legal status under state law. Section 233A of the Kentucky Constitution bars the state from recognizing “a legal status identical or substantially similar to that of marriage for unmarried individuals,”1Kentucky Legislative Research Commission. Kentucky Constitution Section 233A which means Kentucky has no statewide domestic partnership or civil union registry. A few cities offer limited local registries, but those don’t substitute for marriage. If you and your partner want legal protection for property, medical decisions, inheritance, and children, you have to assemble it yourself through private documents.
Why Kentucky Has No Statewide Registry
Kentucky voters approved Section 233A in 2004. It defines marriage as between one man and one woman and separately bans any legal status “substantially similar” to marriage for unmarried people.1Kentucky Legislative Research Commission. Kentucky Constitution Section 233A The U.S. Supreme Court’s 2015 decision in Obergefell v. Hodges struck down state bans on same-sex marriage,2Justia. Obergefell v. Hodges, 576 U.S. 644 (2015) but the second clause of Section 233A remains on the books. That’s the clause blocking the legislature from creating a domestic partnership or civil union system. Civil unions fall under the same ban.
One related point worth knowing: Kentucky does not recognize common-law marriage formed inside the state. A couple can live together for decades, share finances, and present themselves as married, and still have no marital rights under Kentucky law. Kentucky will recognize a common-law marriage validly formed in another state that allows it, but you can’t create one by cohabiting here.
Local City Registries
Louisville, Covington, and Berea each operate some form of domestic partnership registry at the city level. These are meaningful as recognition, but their legal reach is narrow. A municipal registry cannot grant inheritance rights, tax benefits, or custody presumptions, because state law controls those. What local registries can do varies by city and typically touches things like benefits for city employees and hospital visitation recognition within that jurisdiction.
If you live in one of these cities, the city clerk’s office handles current forms and requirements. A local registration carries no weight once you cross the city line, and it is not a substitute for the documents below.
The Documents That Fill the Gap
Without state recognition, Kentucky partners build their own safety net one document at a time. These are the pieces that cover most of what marriage would otherwise provide automatically.
Cohabitation or partnership agreement. A written contract covering how you share expenses, divide property if you separate, and handle jointly acquired assets. Kentucky courts treat these as ordinary contracts, so specificity matters. Vague language like “we’ll split everything fairly” invites disputes. Name accounts, describe property, and spell out who gets what. Drafting fees for a comprehensive agreement typically run $500 or more depending on complexity.
Advance directive and healthcare surrogate designation. Kentucky’s advance directive statute (KRS 311.621 through 311.643) lets you name any adult as your healthcare surrogate.3Kentucky Legislative Research Commission. Kentucky Revised Statutes 311.621 – Definitions for KRS 311.621 to 311.643 Without this document, your partner has no automatic authority to make medical decisions for you. Kentucky’s default surrogate priority list favors spouses and blood relatives, and an unmarried partner is not on it.
Durable power of attorney. Kentucky’s Uniform Power of Attorney Act (KRS Chapter 457) lets you appoint your partner as your agent for financial matters, including bank accounts, bills, and real estate transactions. A durable power of attorney stays in force if you become incapacitated, which is precisely when you need it.
Will or trust. Kentucky’s intestate succession rules send a deceased person’s property to a surviving spouse, children, parents, and other blood relatives. An unmarried partner inherits nothing by default. A will naming your partner as a beneficiary is the floor. A revocable living trust goes further by avoiding probate, which keeps the transfer private and faster.
Beneficiary designations. Life insurance, retirement accounts, and payable-on-death bank accounts pass directly to the named beneficiary, bypassing the will and probate. Review these designations whenever your life changes. Kentucky does not allow transfer-on-death deeds for real property, so this shortcut is not available for a house or land.
No single document replaces what marriage provides automatically. Together they cover most of the same ground, but only if you keep them current. When circumstances change (you buy a house together, have a child, one partner becomes seriously ill), revisit every document.
Hospital Visitation and Medical Decisions
Visitation and decision-making are two different things, and the law treats them differently.
On visitation, federal law offers protection regardless of Kentucky’s position. Under Medicare and Medicaid participation rules, any hospital in those programs must let patients designate their own visitors, “including, but not limited to, a spouse, a domestic partner (including a same-sex domestic partner), another family member, or a friend.”4eCFR. 42 CFR 482.13 – Condition of Participation: Patient’s Rights Hospitals cannot restrict visitation based on race, sex, sexual orientation, gender identity, or disability.5HHS.gov. FAQs on Patient Visitation at Certain Federally Funded Entities and Facilities
Decision-making is separate. A hospital must let your partner visit, but staff still need written authorization before your partner can consent to procedures, access medical records, or make end-of-life decisions. That authorization is the advance directive naming your partner as your healthcare surrogate. Keep a copy on your phone, give one to your partner, and file one with your primary care doctor. In an emergency, the document needs to be reachable in minutes, not locked in a filing cabinet.
Property, Inheritance, and What Happens at Death
Married couples in Kentucky get a detailed statutory framework for dividing property. Under KRS 403.190, a court divides marital property “in just proportions” based on each spouse’s contribution, the length of the marriage, and economic circumstances.6Justia Law. Kentucky Revised Statutes 403.190 – Disposition of Property Domestic partners get none of that. If an unmarried couple separates and only one partner’s name is on the deed, the other may have no legal claim to the property no matter how much they put into mortgage payments or improvements.
Joint ownership closes part of the gap. Two unmarried people can hold title as joint tenants with right of survivorship, so if one dies, the other automatically takes full ownership outside probate. Tenancy in common is the alternative, where each partner owns a defined share that passes through their estate. For most couples who want the survivor to keep the home, joint tenancy is the safer choice. Because Kentucky does not allow transfer-on-death deeds for real property, joint tenancy or a trust are the primary tools for keeping a shared home out of probate.
For bank accounts, investment accounts, and retirement funds, payable-on-death and transfer-on-death designations do the same work. Name your partner as the beneficiary and the account passes directly. Without those designations, intestate succession controls, and those rules send assets to legal spouses, children, parents, and siblings. An unmarried partner receives nothing.
Taxes, Social Security, and Employer Benefits
Unmarried partners cannot file a joint federal return. The IRS sets filing status by marital status on the last day of the tax year, and domestic partnership does not count as marriage for federal purposes.7Internal Revenue Service. Filing Status Each partner files single, or head of household if they paid more than half the cost of maintaining a home for a qualifying dependent.
One benefit couples sometimes miss: if your partner has little or no income and lives with you for the full year, you may be able to claim them as a qualifying relative dependent. The IRS requires that the person’s gross income fall below a threshold adjusted annually for inflation, that you provide more than half their support, and that they live with you as a member of your household all year.8Internal Revenue Service. Dependents Kentucky has no law against cohabitation, so the local-law requirement is not a barrier. Check the current year’s income threshold before claiming.
Other federal advantages reserved for marriage stay out of reach. You cannot make tax-free gifts to your partner under the unlimited marital deduction. The federal estate tax exemption applies individually, with no portability between unmarried partners. Employer-provided health insurance covering a domestic partner is treated as taxable income to the employee unless the partner qualifies as a tax dependent.
Social Security is the sharpest gap. Spousal and survivor benefits are available only to legally married spouses. An unmarried partner cannot draw benefits on their deceased partner’s record, no matter how long the couple lived together, owned property jointly, or raised children together. There is no exception for long-term partnerships. A surviving spouse can receive up to 100% of the deceased spouse’s benefit; an unmarried partner receives zero. For couples where one partner earns significantly more, the higher earner should plan around this gap with life insurance or other tools so the surviving partner is not left without income.
On the employer side, Kentucky law does not require private employers to extend benefits to domestic partners. Some do, many don’t. Ask your HR office what the policy actually says before you assume coverage.
Children of Unmarried Parents
When unmarried partners have children, parentage drives custody and support, not partnership status. The birth mother is automatically a legal parent. For a father, establishing legal paternity through a voluntary acknowledgment at the hospital or a court order is the first step. Without legal paternity, a father has no automatic right to custody or visitation.
Once parentage is established, Kentucky courts decide custody using the same best-interests factors they apply in divorce cases. Unmarried parents file separate petitions for custody and child support instead of folding them into a dissolution. Child support guidelines are the same regardless of whether the parents were ever married.
Same-sex couples face a sharper issue. If only one partner is the biological or adoptive parent, the other may have no legal relationship with the child at all unless they complete a second-parent or stepparent adoption. A co-parenting agreement alone is risky, because Kentucky courts are not bound to enforce such agreements the way they would enforce a legal parent’s rights. Adoption is the most reliable way to protect the non-biological parent’s relationship.
If the Relationship Ends
Because Kentucky has no formal dissolution process for domestic partnerships, ending one looks more like unwinding a business arrangement than ending a marriage. If you have a written cohabitation agreement, that document controls. It should spell out how jointly owned property gets divided, who takes which debts, and how shared accounts are handled. A well-drafted agreement makes separation straightforward, if not painless.
Without an agreement, it gets messy. You cannot file for divorce because you were never married. Disputes over shared property or finances end up in civil court under general contract and property law. The court looks at whose name is on the title or account, whether there was an oral or implied agreement, and what each person contributed. The outcome is far less predictable than divorce, where statutory guidelines give courts a clear framework. Judges in these cases are improvising within contract law, and results vary widely.
If you registered with a local domestic partnership registry in Louisville, Covington, or Berea, check that city’s procedure for dissolving the registration. It’s usually a simple administrative step, but skipping it can create confusion about your status with the city and any benefits tied to the registration.
Custody and support run on their own track. Either parent can petition family court regardless of the parents’ relationship status, and courts apply the same best-interests standard they use in divorce. Without a divorce case to bundle everything together, you may need to file separate actions for property disputes and custody, potentially in different courts.
