COHABITATION AGREEMENT
State Of Washington - Living-together Agreement
PARTNER 1
Olivia J. Carter
500 Lakeview Road, Seattle, WA 98101
By: (206) 555-0101, olivia.c@email.com
PARTNER 2
Nathan A. Wright
210 Pine Street, Bellevue, WA 98004
By: (206) 555-0202, nathan.w@email.com
Shared Residence: 500 Lakeview Road, Seattle, WA 98101
Effective April 1, 2026
This Cohabitation Agreement (this "Agreement") is entered into by and between Olivia J. Carter and Nathan A. Wright (collectively, the "Partners") to establish their respective rights and obligations while residing together.
1.
PURPOSE AND RECITALS
Olivia J. Carter and Nathan A. Wright ("the Partners") enter into this Cohabitation Agreement voluntarily and in good faith to establish their respective rights and obligations while residing together at 500 Lakeview Road, Seattle, WA 98101. This Agreement shall take effect on April 1, 2026. The Partners acknowledge the common-law recognition of express and implied agreements between unmarried cohabitants reflected in Marvin v. Marvin, 18 Cal. 3d 660 (1976), and analogous decisions in other jurisdictions; the Restatement (Third) of Restitution and Unjust Enrichment §28 (2011) likewise permits restitutionary remedies between cohabitants in appropriate cases. This Agreement is intended to memorialize the Partners’ express understanding and to displace any implied-contract, quantum-meruit, or unjust-enrichment inference that might otherwise arise.
2.
SHARED RESIDENCE
The Partners agree to reside together at 500 Lakeview Road, Seattle, WA 98101. The residence is: Olivia J. Carter (sole owner/leaseholder). This Agreement does not create any ownership rights in the property for the non-owning partner unless otherwise stated herein.
3.
SEPARATE PROPERTY
Partner 1 retains sole ownership of: 2021 Toyota Prius, personal savings account at Chase (#8821), family artwork.
Partner 2 retains sole ownership of: Vanguard investment account (#4433), laptop and home office equipment, personal bicycle.
Because the Partners are not married, federal tax filing status is determined under IRC §7703, and a non-spouse cohabitant is not a "dependent" absent the support and residency tests of IRC §152. Federal retirement spousal-protection rules — including ERISA §205 / IRC §417 qualified joint-and-survivor annuity rights and ERISA §206(d)(3) QDRO transfers (29 U.S.C. §1055, 29 U.S.C. §1056(d)(3)) — apply only to legal spouses and are not created by this Agreement. Estate rights similarly depend on state intestacy statutes and written estate instruments; each Partner should execute a separate will, beneficiary designation, and healthcare directive to effect any desired transfers at death.

GENERAL PROVISIONS
(a) Non-Marital Status: Nothing in this Agreement shall be construed to create a marriage, common-law marriage, or registered domestic partnership unless otherwise recognized by law. Where state law expressly recognizes registered partnerships (see, e.g., Cal. Fam. Code §§297-297.5), this Agreement is supplemental to and does not by itself effect such registration.
(b) Governing Law: This Agreement shall be governed by the laws of the State of Washington. The Partners acknowledge that state approaches to cohabitation contracts vary — most jurisdictions enforce them following Marvin v. Marvin, 18 Cal. 3d 660 (1976), and Illinois has endorsed such enforcement in Blumenthal v. Brewer, 2016 IL 118781, overruling in relevant part Hewitt v. Hewitt, 77 Ill. 2d 49 (1979).
(c) Severability: If any provision is found unenforceable, remaining provisions remain in effect.
(d) Amendment: This Agreement may be modified only by written instrument signed by both Partners.

What is a Cohabitation Agreement?
A cohabitation agreement is a legally binding contract between unmarried partners or domestic partners who are living together in the United States. It documents how property, finances, and household responsibilities are managed, providing legal clarity and protection for both parties under U.S. contract law.
American unmarried couples, domestic partners, and civil union partners living together benefit from having a cohabitation agreement. Couples who maintain separate finances, own property individually, or want to protect separate assets should consider documenting their arrangement. This is particularly important for same-sex partners and those in U.S. jurisdictions without formal domestic partnership recognition.
A comprehensive cohabitation agreement addresses property ownership, shared and separate property rights, financial contributions to household expenses, debt responsibility, management of joint bank accounts, household responsibilities, pet ownership, and procedures if the relationship ends. In the United States, it can also address inheritance, health care decisions, and tax filing status.
Unmarried U.S. couples do not have the same legal protections as married couples under American law. Without a cohabitation agreement, state law may not recognize shared property rights or provide protections to the surviving partner upon death. A cohabitation agreement creates contractual protections that marriage automatically provides under United States law, ensuring both parties understand their rights and obligations.

How to Create Your Cohabitation Agreement
- 1
Inventory all separate and shared property
Create a detailed list of property each party owned before cohabitation and property acquired together. Include real estate, vehicles, bank accounts, investments, retirement savings, furniture, and personal items. Document separate property clearly to distinguish from jointly owned assets.
- 2
Agree on expense sharing
Determine how household expenses will be divided. Discuss rent, utilities, groceries, insurance, and household maintenance. Decide whether costs will be split equally, proportionally to income, or by specific categories. Document the percentage or amount each party contributes.
- 3
Define ownership of joint purchases
Clarify ownership of items purchased together during cohabitation. For major purchases like furniture, electronics, or vehicles, specify whether they are joint property or belong to whoever paid for them. This prevents disputes if the relationship ends.
- 4
Address separation procedures
Outline what happens if the parties separate. Include how joint property will be divided, how shared expenses will be settled, and timelines for one party to move out. Specify how rent or lease obligations will be handled if one party leaves.
- 5
Sign with witnesses
Both parties should sign the agreement and date it. Having witnesses present when both parties sign strengthens enforceability. Consider having the agreement notarized for additional legal weight, though not always required in every state.

Legal Considerations
Cohabitation agreements vary in enforceability and legal effect depending on your state and the specific terms. Understanding key legal concepts helps ensure your agreement is comprehensive and will be enforced if needed.

Reviewed by legal professionals. The content on this page and the template clauses have been reviewed by licensed attorneys in the United States to ensure accuracy and legal soundness for standard scenarios.
Not a Marriage or Civil Union
A U.S. cohabitation agreement does not create marital status or the legal rights of marriage. It is a contract between two parties under American law. Unmarried partners do not automatically inherit from each other or receive spousal benefits unless specified in a will or other United States estate planning document.
Varies by State
U.S. state laws governing cohabitation agreements differ significantly. Some American states recognize and enforce them readily, while others have restrictions on certain terms. Your state may have specific requirements for enforceability, such as signatures by both parties or independent legal representation.
Property Rights for Unmarried Partners
Without a cohabitation agreement, most U.S. states treat unmarried partners as separate individuals with no presumption of shared property rights. This means property acquired in one partner's name belongs to that partner under American law, even if both contributed. A cohabitation agreement clarifies who owns what.
Palimony Claims
In some states, one unmarried partner can claim support from the other upon separation, similar to alimony in divorce. This is called palimony. Your cohabitation agreement should address whether support payments are expected or waived.
