Co-Mingled Property in Divorce: What It Is and How to Handle It
Dividing assets during a divorce can be a complicated process, especially when it comes to co-mingled property. Co-mingling happens when separate assets, like property you owned before your marriage, are mixed with marital assets during the marriage. This can happen with bank accounts, businesses, real estate, and more. Understanding how to handle co-mingled property is important to make sure assets are divided fairly through a divorce.
What is Co-Mingled Property?

Co-mingled property refers to assets that are mixed between you and your spouse. For example, you may have started a marriage with a car, a bank account, or a business that you owned before you were married. Over time, however, you might have added joint deposits or shared expenses, which creates a mix of separate and shared property.
A common example of co-mingled property is a joint bank account. If you or your spouse deposit both pre-marital and marital funds into the same account, it becomes difficult to tell how much belongs to whom. This same idea applies to homes, cars, retirement accounts and even businesses that may have started as individual assets but became mixed over time. As a result, determining what belongs to whom can become complicated when it’s time to divide assets in a divorce.
How Do You Deal with Co-Mingled Property During Divorce?
When it comes to dividing property in a divorce, dealing with co-mingled assets can get tricky. Since the property is mixed, it can be difficult to figure out how much of it is considered marital (belonging to both spouses) and how much remains non-marital (belonging to one spouse.
In many cases, you may need to hire a forensic accountant to review records and determine the value of the non-marital portion of the asset. For example, if one spouse had a bank account before marriage but continued to add money during the marriage, an accountant can help separate the two types of funds.
It’s important to note that co-mingling doesn’t only apply to physical assets like property and bank accounts—it can also apply to student debt. Some states treat student loans as marital debt if one spouse paid them off during the marriage, while others may classify them as a non-marital debt if the loan was incurred before the marriage. This can create confusion, especially if the other spouse has contributed toward paying off the debt. In such cases, a legal professional may be needed to help clarify the situation and determine the fair division of responsibility for the debt.
How to Avoid Co-Mingling Assets
If you want to avoid the hassle of co-mingling, there’s a simple rule: keep individual assets in your own name. If you don’t want something to become marital property, don’t add it to joint accounts or put it in both names. If you’re unsure about how to protect your assets, consider a prenuptial agreement. This can give you peace of mind knowing your individual property will remain separate.
