A more thorough explanation:

A portable business is a collection of legal clients that an attorney can take with them when they move from one law firm or location to another. This can be done with minimal loss of client relationships. It is also known as a portable practice.

• An attorney who has built up a loyal client base over the years may decide to leave their current law firm and take their clients with them to a new firm.
• A lawyer who specializes in a particular area of law, such as intellectual property, may be able to take their clients with them when they move to a new city or state.

These examples illustrate how a portable business can be beneficial for attorneys who want to maintain their client relationships while transitioning to a new firm or location.
