How Unmarried Co-Buyers Can Protect Themselves When Taking Title

The Public Deed and the Private Story

I remember sitting at a closing table in Arlington a few years ago with two lifelong friends. They were thrilled, pooling their resources to buy a classic brick townhouse they could never have afforded alone. As they passed the pen back and forth, signing the mountain of documents, one of them looked at me. “So the deed says we’re 50/50 owners,” she said quietly. “But I put down about 70% of the cash to close. How does that work?”

It’s a fantastic question, and it gets to the heart of a common misunderstanding. Many people believe the deed to their property tells the whole story of their ownership. In reality, it only tells the public part. For unmarried co-buyers, learning how to protect themselves means understanding the difference between what the deed says and what a private agreement can, and should, do.

The deed is a powerful legal instrument. It’s the official document that transfers property from seller to buyer. Once recorded in the local land records—whether in Washington, D.C., Montgomery County, or Fairfax County—it serves as public notice of who now owns the home. When multiple unmarried people buy a property, the deed must specify *how* they are sharing that ownership. This is known as their “tenancy.”

Tenants in Common vs. Joint Tenants: A Fork in the Road

In our region, unmarried co-owners generally hold title in one of two ways. Understanding the distinction is the first step toward protecting your interests.

Tenants in Common (TIC) is the default in D.C., Maryland, and Virginia if the deed doesn’t specify otherwise. Think of it like owning shares in a company. Each co-owner holds a distinct, individual percentage of the property. It can be 50/50, but it doesn’t have to be. It could be 70/30 to reflect unequal down payments, or any other split. The crucial point here is that these shares are inheritable. When a Tenant in Common dies, their ownership stake passes to the heirs named in their will or, if there’s no will, according to state law. It does *not* automatically go to the other co-owner(s).

Joint Tenants with Right of Survivorship (JTWROS) operates on a “last one standing” principle. Under this structure, each co-owner has an undivided interest in the *entire* property, not just a specific share. The “right of survivorship” is the key feature: when one joint tenant dies, their interest is automatically absorbed by the surviving joint tenant(s). This transfer happens outside of the probate process, which can be a significant advantage. To create this type of tenancy, the deed must contain very specific language, such as “as joint tenants with right of survivorship, and not as tenants in common.”

While choosing the right tenancy is important, especially for estate planning, it still doesn't answer my client's question from that Arlington closing. What about the money?

Why the Deed Alone Isn't Enough Protection for Unmarried Co-Buyers

The deed is a blunt instrument. It declares who owns the property and what happens if an owner dies. It says nothing about the financial realities of co-ownership or the “what ifs” of life.

Consider these common scenarios:

• Unequal Contributions: Like the friends I mentioned, one person may contribute the bulk of the down payment while the other has a higher income and will cover more of the mortgage. A 50/50 ownership split on the deed doesn't reflect this reality.
• Ongoing Expenses: A new roof on a home in Bethesda or a boiler replacement in a Dupont Circle condo can cost tens of thousands of dollars. Who is responsible for what portion of major repairs versus daily maintenance?
• An Exit Strategy: What happens if, five years down the road, one person gets a job in another state and needs to sell? What if a romantic relationship ends? If one owner wants to sell and the other doesn't, you can find yourselves at an impasse.

Without a clear plan, the only legal remedy for a deep disagreement is often a “partition sale.” This is a court-ordered action to force the sale of the property and divide the proceeds. It is a costly, time-consuming, and emotionally draining process that almost always damages both the financial investment and the personal relationship. It is the last resort you want to actively plan to avoid.

The Co-Ownership Agreement: Your Private Blueprint

The real protection for unmarried co-buyers isn’t found in the public deed, but in a separate, private contract. Often called a Co-Ownership Agreement or a Property Agreement, this document is your shared instruction manual for the investment. Think of it as a pre-nuptial agreement for your property.

Creating this agreement isn’t a sign of distrust; it’s an act of clarity and care. It forces a practical conversation up front, turning ambiguity into a concrete plan. A well-drafted agreement, prepared with the help of an attorney, typically addresses:

• Ownership Percentages: It can state that while the deed may list two owners, their actual equity is split, for example, 70/30 to reflect the down payment.
• Financial Responsibilities: It outlines who pays what percentage of the mortgage, property taxes, insurance, HOA fees, and utilities.
• Repairs and Improvements: It sets a threshold for what constitutes a major repair and how it will be funded.
• An Exit Plan: This is the most critical part. It can establish a “right of first refusal,” giving one owner the first opportunity to buy out the other if they want to sell. The agreement can define the process for getting the property appraised and calculating a fair buyout price that accounts for the initial investment. It provides a clear, predictable path for untangling your shared finances without resorting to litigation.

The deed makes you co-owners in the eyes of the law. A co-ownership agreement makes you partners in a shared financial future. It provides the detailed map for your journey together, anticipating the forks in the road and giving you a peaceful way to navigate them.

Buying a home with someone is an optimistic act. It’s a bet on a shared future. The smartest way to honor that optimism is to prepare for the unexpected with honesty and foresight. By having these conversations and formalizing them, you aren’t planning for failure; you’re building a stronger foundation for success, protecting both your friendship and your investment for whatever comes next.
