commingle

1. In securities, it 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.

3. In real estate, it is the illegal act of a broker combining clients' funds with personal funds because, by law, a broker is required to use a separate trust or escrow fund to temporarily hold a client's funds.

Investopedia Says:
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.

Send two pieces of mail of different classes through the postal system together. Commingled mail might be subscriber and nonsubscriber copies of a periodical or machinable and irregular parcels. If the mailer wants both pieces to receive the same level of service, postage is charged on both pieces at the rate of the higher of the two classes. A comingled mailing can also be charged at each class rate as if the mail pieces were mailed separately and receive the service level of the lower class. However, invoices must be mailed at First-Class rates regardless of the class of the partner mailing piece and the level of service desired by the mailer. U.S. Postal Service approval may be required before commingling. For example, an invoice might be enclosed with a magazine in a poly bag. The magazine will mail at periodicals class rates, but the invoice will mail at First-Class rates. A renewal notice, which normally mails Standard Mail (A), may be attached with adhesive to the cover of a magazine and mailed at Periodicals class rates along with the magazine. In both cases, service will be at a level equal to the lowest class.
