Kentucky does not offer a domestic partnership in the way many other states do. The state constitution blocks any statewide registry or civil union, so unmarried couples cannot sign up for a legal status that carries marriage-like rights. A few Kentucky cities run their own limited registries, and every couple can build protection through private legal documents, but there is no state-level equivalent to marriage available to unmarried partners.
That gap matters more than it sounds. Without paperwork in place, an unmarried partner in Kentucky has no automatic say in medical decisions, no inheritance rights, and no claim on shared property beyond what their name is on. The good news is that most of those protections can be assembled document by document. You just have to do it yourself.
Why Kentucky Has No Statewide Registry
In 2004, Kentucky voters added Section 233A to the state constitution. It does two things: defines marriage as between one man and one woman, and bars recognition of 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 ruling in Obergefell v. Hodges made same-sex marriage legal nationwide, but it did not touch that second clause.2Justia. Obergefell v. Hodges, 576 U.S. 644 (2015)
That second clause is the reason the legislature cannot create a domestic partnership or civil union registry. Doing so would take a constitutional amendment or a federal court ruling that Section 233A is unenforceable. Neither has happened.
City Registries in Louisville, Covington, and Berea
A few Kentucky cities have set up their own domestic partnership registries. Louisville, Covington, and Berea each offer some form of local registration. These are meaningful as recognition, but their legal reach is narrow. A city registry cannot override state law to grant inheritance rights, tax benefits, or custody presumptions.
What a local registration typically does cover is limited to certain city employee benefits and hospital visitation recognition within that municipality. It carries no weight once you leave the city’s jurisdiction, and it does not substitute for the private legal documents below. If you live in one of these cities and want to register, the city clerk’s office has the current forms and requirements.
The Documents That Do the Work
Without a state status to fall back on, unmarried couples in Kentucky have to build their own protections. These are the tools that matter most:
- Cohabitation agreement. A written contract covering how you share expenses, divide property if you separate, and handle jointly acquired assets. Kentucky courts treat these as regular contracts, so specificity matters. Vague language like “we’ll split things fairly” invites disputes. Name accounts, describe property, and spell out who gets what. Attorney fees 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. Without this document, your partner has no automatic authority to make medical decisions for you. The state’s default surrogate priority list favors spouses and blood relatives.3Kentucky Legislative Research Commission. Kentucky Revised Statutes 311.621 – Definitions for KRS 311.621 to 311.643
- Durable power of attorney. Kentucky’s Uniform Power of Attorney Act lets you appoint your partner to handle financial decisions, including bank accounts, bills, and real estate. A “durable” designation means the authority survives your incapacity, which is when you need it most.
- Will or living trust. Kentucky’s intestate succession laws send a deceased person’s property to a surviving spouse, children, parents, and blood relatives. An unmarried partner inherits nothing by default. A will naming your partner is the minimum. A revocable living trust goes further by keeping the transfer out of probate.
- Beneficiary designations. Life insurance, retirement accounts, and payable-on-death bank accounts each let you name a beneficiary directly, bypassing the will. Review them regularly. Kentucky does not allow transfer-on-death deeds for real property, so this shortcut is not available for a house or land.
None of these individually replaces what marriage provides automatically. Together, they cover most of the same ground. When circumstances change (you buy a home together, have a child, one partner becomes seriously ill), revisit every document.
Hospital Visitation and Medical Decisions
Federal rules give unmarried partners a floor of protection here that state law cannot take away. Any hospital participating in Medicare or Medicaid 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
Visitation is not the same as decision-making authority, though. A hospital has to let your partner in the room, but staff still need written authorization before your partner can consent to treatment, see your records, or make end-of-life decisions. That authorization comes from an advance directive naming your partner as your surrogate. Keep a copy accessible. In an emergency, a document in a filing cabinet at home is a document that does not exist. File one with your primary care doctor, keep one in your wallet or on your phone, and make sure your partner has one.
Property and Inheritance
Married couples in Kentucky get court-supervised property division under KRS 403.190, which splits marital property “in just proportions” based on each spouse’s contribution, the length of the marriage, and each spouse’s economic circumstances.6Justia Law. Kentucky Revised Statutes 403.190 – Disposition of Property Unmarried partners get none of that framework. If a couple separates and only one partner’s name is on the deed, the other may have no claim regardless of how much they paid toward the mortgage or improvements.
Joint ownership fixes part of this. Two unmarried people can hold real property as joint tenants with right of survivorship, meaning the surviving partner automatically takes full ownership if the other dies, outside probate. Tenancy in common is the other option, where each partner owns a defined share that passes through their estate. For a couple who wants the survivor to keep the home, joint tenancy is usually the safer pick. Because Kentucky does not permit transfer-on-death deeds for real property, joint tenancy or a trust are the main 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 similar work. Name your partner, and the account passes directly. Without those designations, Kentucky’s intestate rules send assets to legal spouses, children, parents, and siblings, and an unmarried partner receives nothing.
Children and Parenting Rights
When unmarried partners have children together, parentage rather than partnership status controls custody and support. The birth mother is automatically a legal parent. A father needs to establish legal paternity, either through a voluntary acknowledgment at the hospital or through a court order. Without it, he has no automatic right to custody or visitation.
Once parentage is established, Kentucky courts apply the same best-interests factors they use in divorce cases. Unmarried parents file separate petitions for custody and child support rather than folding those issues into a dissolution. Child support obligations follow the same guidelines whether the parents were married or not.
Same-sex couples face an added layer. If only one partner is the biological or adoptive parent, the other may have no legal relationship with the child unless they complete a second-parent or stepparent adoption. A co-parenting agreement alone is risky, because Kentucky courts are not bound to enforce it the way they would enforce a legal parent’s rights. Adoption is the reliable path.
Taxes, Social Security, and Employer Benefits
Federal benefits reserved for married couples stay out of reach no matter what documents you sign. Unmarried partners cannot file a joint federal return. The IRS uses marital status as of 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 as single, or as head of household if they paid more than half the cost of a home for a qualifying dependent.
One overlooked option: if your partner has little or no income and lives with you the entire year, you may be able to claim them as a qualifying relative dependent. The IRS requires that their gross income fall below a threshold (adjusted annually), 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 prohibiting cohabitation, so the local-law piece of that test should not be an obstacle. Check the current year’s income threshold.
Unmarried partners also miss the unlimited marital deduction for gifts and estate transfers, and employer-provided health insurance covering a 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 legal spouses. An unmarried partner receives nothing based on the other’s earnings record, regardless of how long they lived together, whether they owned property jointly, or whether they had children. There is no exception for long-term partnerships. For couples where one partner earned significantly more, this is often the single most consequential financial difference between marrying and not marrying. If marriage is off the table, life insurance or other planning can help close the gap.
On the employer side, Kentucky does not require private employers to extend benefits to domestic partners. Some do, many do not. Check your specific plan.
If the Relationship Ends
Kentucky has no dissolution process for domestic partnerships, so 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 specify how jointly owned property gets divided, who takes on which debts, and how shared accounts are handled.
Without an agreement, disputes over shared property or finances land in civil court under ordinary contract and property law. A court looks at whose name is on the title, whether there was an oral or implied agreement, and what each person contributed. The outcome is less predictable than a divorce, where statutory guidelines give judges a clear framework.
If you registered locally in Louisville, Covington, or Berea, check that city’s procedure for ending the registration. It is usually a simple administrative step, but skipping it can create confusion about your status and any city-linked benefits.
Custody and support run on their own track. Either parent can petition family court for orders regardless of the couple’s relationship status. Without a divorce case to bundle everything together, you may need separate actions for property and custody, potentially in different courts.
