What is the legal term for the sale of a property under a certain agreement?

The legal term for the sale of a property under a certain agreement is known as a listing agreement. A listing agreement is a contract between a property owner and a real estate agent, granting the agent the authority to market and sell the property on behalf of the owner.

In this context, the listing agreement outlines the terms and conditions under which the agent will represent the seller, including aspects such as the sale price, commission structure, and the length of time the property will be listed for sale. This agreement is essential because it formalizes the relationship between the seller and the agent, ensuring both parties understand their rights and obligations throughout the sale process.

The other options, while related to real estate, do not specifically pertain to the sale of property under an agreement in the same way a listing agreement does. Joint tenancy refers to a type of ownership arrangement between two or more persons. An agency relationship denotes the broader concept of a legal relationship where one party (the agent) acts on behalf of another (the principal), but it does not specify the sale agreement context. A lease option is a type of agreement that gives a tenant the right to purchase property at a predetermined price after a certain period, rather than immediately selling it.
