Is a Cohabitation Agreement Right for Me?

Marriage isn’t the right choice for every couple. However, couples can face challenges without the legal protections that come with marriage. A cohabitation agreement can spell out how to handle finances, property ownership, or parenting responsibilities.

Cohabitation agreements establish legal protections for couples who live together but aren’t married. If you’re cohabiting and intend to remain unmarried for an extended period of time, talk to a family law attorney for legal advice.

A cohabitation agreement provides crucial protection and clarity for domestic partners. Marilea Lewis, a top-rated attorney representing families at Duffee + Eitzen in Dallas, Texas, explains that there’s a variety of statuses when it comes to relationships. “You can be married, you can be single, you can be divorced, you can be widowed. And there are cohabitation agreements, which are contractual in nature.”

Cohabiting partners don’t automatically have legal rights to shared property, financial support, or decision-making authority. This leaves cohabiting couples without the legal safety nets that marriage provides.

A cohabitation agreement can establish legal protection for couples with an enforceable and binding agreement. It provides a legal framework to address shared responsibilities and protect individual rights.

If you and your partner own property together, it’s important to establish clear guidelines and legal documentation as to who owns what. A cohabitation agreement can protect property ownership. It can define ownership and management rights of real estate, personal property, or other assets. This is especially important for jointly purchased assets acquired during the relationship. Should the couple separate, the cohabitation agreement will outline the property division.

Similarly, spell out all your agreements regarding shared and separate property, including bank accounts, cars, savings and investments, financial support, retirement, health insurance policies, household items, and gifts.

During the relationship, the couple will have an agreement in place for how to handle living expenses. The cohabitation agreement formalizes financial responsibilities, like rent, mortgage payments, and other household expenses. In some situations, the couple may agree to financial support paid by one individual to the other. This is palimony, which is similar to alimony paid when a married couple divorces.

The court often treats cohabitating unmarried partners as non-family members. Cohabitation agreements include estate planning documents. A cohabitation agreement complements wills, trusts, and powers of attorney to provide comprehensive protection.

Financial Considerations Covered by Cohabitation Agreements

For many romantic partners, a cohabitation agreement provides financial protection. The partners can clearly define how to pay bills, whether one person is paying or dividing them between the partners. This agreement can address shared expenses, such as a mortgage, vehicle payments, credit card debt, taxes, and insurance. It can also address daily bills, such as utility bills, groceries, and home maintenance. Having an agreement in writing can reduce the risk of conflict later on.

Individuals come to the relationship with their own financial assets and debts. The cohabitation agreement ensures each party keeps the assets with which they came into the relationship. It also ensures that assets acquired before or during the relationship remain with the rightful owner. The couple can stipulate that certain debts remain the responsibility of one individual. In addition, they may agree that one party provides ongoing financial support to the other in the event of a breakup.

Child-Related Provisions in Cohabitation Agreements

A couple that has children but isn’t married faces a unique challenge. They share the responsibility of caring for and raising their children. A cohabitation agreement can outline parenting responsibilities and schedules, but child custody is determined by the court based on the childrens’ best interests. Agreeing to these terms early can make the separation process easier when the relationship ends.

Common custody details included in a cohabitation agreement include parenting schedules, decision-making responsibilities, and the dispute resolution process. It will also outline financial contributions for the child’s expenses, including education, healthcare, and extracurricular activities. The couple can agree on daily responsibilities and how to handle things like medical care.

Having an agreement in place in advance protects the couple and the children. There is greater stability for the children because there is a clear framework for caregiving and financial support. It reduces uncertainty and stress for children during transitions or disputes.

While couples have broad freedom to create an agreement with terms that work for them, they must abide by the applicable state law. In addition, the court will retain the final say on matters pertaining to the children’s best interests.

How To Proceed with a Cohabitation Agreement

Once a couple decides to create a cohabitation agreement, they should discuss their goals for having the agreement. Determining the primary driving factors can help guide the couple in creating the terms of the agreement. Examples could include protecting property ownership and finances or outlining parenting responsibilities.

With goals in mind, it is time to consult a family law attorney. The lawyer will discuss the couple’s goals and reasons for creating the agreement. The attorney will guide the couple through the drafting process to ensure legal compliance.

You can be married, you can be single, you can be divorced, you can be widowed. And there are cohabitation agreements, which are contractual in nature.

Typically, each individual in the relationship should seek their own legal representation. There is the potential for a conflict of interest if a single attorney represents both individuals. The lawyer’s job is to protect the best interests of their client. This can conflict, as the couple’s best interests could conflict with each other. Having independent attorneys ensures each partner is fairly represented. Independent legal advice helps verify a balanced and legally binding agreement.

Lewis speaks about her time as a judge. Her experience allowed her to see firsthand the potentially expensive and devastating consequences of couples attempting to draft their own cohabitation agreement. “In community property, there’s some language that can really cause you to have real issues. When I was on the bench, I saw couples who had made major mistakes in many areas. There’s not necessarily magic language, but there’s some real ‘gotcha terms.'”
