A more thorough explanation:

A brokerage contract is an agreement between a principal and a broker, where the broker is authorized to make contracts on behalf of the principal. The broker receives a commission for their services.

For example, if a homeowner wants to sell their house, they may sign a brokerage contract with a real estate agent. The agent will then market the property, find potential buyers, and negotiate the sale on behalf of the homeowner. Once the sale is complete, the agent will receive a commission based on the sale price.

Another example is a stockbroker who is hired by an investor to buy and sell stocks on their behalf. The investor signs a brokerage contract with the broker, who then executes trades based on the investor's instructions. The broker receives a commission for each trade made.

These examples illustrate how a brokerage contract allows a principal to delegate the authority to make contracts to a broker, who acts as their agent. The broker is compensated for their services through a commission, which is typically a percentage of the transaction value.
