Commingling (commingled), in securities, is the mixing of customer-owned securities with brokerage-owned securities.

2. In trust banking, it is the pooling of individual customer accounts into a fund, a share of which is owned by each contributing customer. This is similar to a mutual fund.

BREAKING DOWN 'Commingling (Commingled)'

In all contexts, commingling is mixing funds so that they are considered the same material fund. For example, if you deposit a paycheck into an inheritance fund, the paycheck would not be considered separate funds but part of the inheritance fund. Thus, the paycheck is no longer considered separate property from the inheritance.
