Unmarried Couples and Joint Property: Ouster and Partition Actions in New Jersey

Current as of: September 25, 2026 Real Estate Law New Jersey
💔
When unmarried couples split up in New Jersey, they cannot use family court to divide joint real estate. Instead, they must file a partition action in the Chancery Division to legally force a property sale or a buyout.

Buying a house with a domestic partner is a major financial commitment, but if the relationship ends, untangling that joint property can be legally complicated. Because New Jersey does not recognize common law marriage, unmarried couples do not have the right to 'equitable distribution' through the family court system. If both of your names are on the deed and your ex refuses to sell or buy you out, your only legal remedy is to file a partition lawsuit. We highly recommend using our US Lawyers Directory to find a real estate attorney experienced in unmarried property disputes to secure your financial future.

Step-by-Step Process: Why Family Court is Not an Option

In New Jersey, family court exclusively handles divorces. Unmarried property disputes belong in the General Equity Part of the Chancery Division. Whether you share a condo in Jersey City, a townhome in Camden, or a house in Freehold, your attorney must file the partition complaint under N.J.S.A. § 2A:56-1. You will start the process by filing Form CN 10517, New Jersey, Superior Court, Civil Case Information Statement alongside your lawsuit at venues such as the Superior Court of New Jersey, Chancery Division, General Equity Part, Jersey City, the Superior Court of New Jersey, Chancery Division, General Equity Part, Camden, or the Superior Court of New Jersey, Chancery Division, General Equity Part, Freehold.

Proving Ouster When One Partner Stays in the Home

A common scenario occurs when one partner is forced to move out (due to a breakup or a restraining order) while the other remains in the joint home. In legal terms, if your ex changes the locks or makes it impossible for you to live there, this is called an 'ouster.' As established in the precedent Baird v. Moore, 50 N.J. Super. 156 (NJ App. Div. 1958), if you can prove ouster, you are legally entitled to charge your ex for half of the fair market rental value of the property for the entire time they lived there alone, which is deducted from their share of the final sale.

Accounting for Mortgage Payments and Upgrades

When the judge orders the partition sale, the court will conduct an equitable accounting phase. If you moved out but continued paying half of the mortgage, or if you solely funded a $30,000 kitchen renovation before the breakup, the court will adjust the final payout to reflect these financial realities. Conversely, if your ex stayed in the house and paid the full mortgage and property taxes alone, they will seek a credit for your half of those expenses.

Mediation vs. Litigation Costs

Because taking a partition action all the way to a trial can cost each partner upwards of $10,000 to $15,000 in attorney fees, mediation is highly encouraged in New Jersey. Many Chancery judges will order the unmarried couple into mediation early in the process. During mediation, an independent legal professional helps the partners negotiate a buyout amount or agree to a voluntary listing with a real estate agent. Settling in mediation can slash your legal bills in half and give you direct control over the timeline, rather than leaving the decision up to a judge.

How Long Does It Take?

If the couple cooperates during early mediation, a voluntary buyout or agreement to sell can be finalized in 3 to 6 months. However, if there are bitter disputes over who paid for what, or claims of ouster requiring a full accounting hearing, a partition lawsuit in the New Jersey Chancery Division will generally take 12 to 18 months from the initial filing to the final distribution of cash.

Frequently Asked Questions (FAQ)

What happens if only my ex's name is on the deed, but I paid half the mortgage?

If you are not on the deed, you cannot file a standard partition action. Instead, your attorney must file a different type of Chancery lawsuit, such as a claim for a 'constructive trust' or unjust enrichment, to prove you have an equitable interest in the home.

Can I force my ex to buy me out?

The court cannot force your ex to secure a new mortgage to buy you out if they do not qualify for a loan. If a buyout is financially impossible, the judge will simply order the house to be sold on the open market.

Do we split the proceeds 50/50?

Not necessarily. While the starting presumption is a 50/50 split if you are joint tenants, the judge will adjust the final numbers based on the 'accounting' phase, looking at who paid for taxes, repairs, and the initial down payment.

What if my ex is destroying the property before the sale?

Your attorney can file an emergency motion in the Chancery Court asking the judge to appoint a receiver to take control of the house, or seek an injunction to physically remove your ex from the premises to preserve the property's value.
