Legal Definitions - comingle

Definition: Comingle (also spelled commingle) means to mix together different funds or properties into one mass. This can happen when a spouse mixes their separate property with marital or community property, or when a fiduciary mixes their personal funds with those of a beneficiary or client.

• A husband and wife have separate bank accounts, but the husband decides to transfer money from his account into their joint account. This is an example of comingle.
• A financial advisor manages the investments of several clients. Instead of keeping each client's funds separate, the advisor puts all the money into one account. This is an example of comingle.

These examples illustrate how comingle involves mixing different funds or properties together. In the first example, the husband's separate property (his money in his account) is mixed with the marital property (the joint account). In the second example, the clients' funds are mixed together instead of being kept separate.
