Only the parties to a contract can amend it and then, only if they both agree to do so. Standard form listing and buyer agency contracts doesn't contain any provision for an early cancellation. As noted, to cancel or otherwise amend a listing or buyer agency contract the seller/buyer and brokerage must both agree.
If you're set on canceling, send a formal request in writing, either via email or certified letter. Be sure to include your property address, the date, and a clear statement that you're terminating the agreement. If you want to work with a different agent in the future, be clear about the termination timeframe.
Termination clauses can always be customized but standard ones are included in almost every agreement.
A listing agreement should include a termination clause to outline conditions under which the property owner or real estate agent can end the contract early.
Whether you change your mind about selling, have ethical or performance concerns about the agent, or you just don't find a buyer, you can get out of a listing agreement. But before you sign one, you should understand your options for terminating a listing agreement so you don't feel stuck in a bad situation.
First off, without a defined expiration date, you didn't have a ratified listing agreement. Second, in California, as of 2024, you cannot have a listing agreement term for longer than 24 months, and if you essentially had an indefinite listing agreement, this would be unlawful.
If I was wanting to cancel, the first thing I would do is contact the listing agent and explain why you want to cancel. Most of the time the listing agent will release you from the agreement. If they are resistant to releasing you from the agreement contact their Broker/manager and explain.
You can indeed cancel a real estate listing agreement in California. Sellers might be asking themselves, “under what circumstances?” And the answer to that is: almost any. Maybe you changed your mind and you decided you don't want to sell your house after all.
California case law suggests that where the listing agreement has a fixed term, it may not be unilaterally terminated by the agent (though the client may unilaterally terminate). The agent may "renounce" the agency, but if the client is damaged by the renunciation, the client may sue for damages.
Listing agreements are usually cancelled only with the mutual consent of the involved parties. Depending on the terms of the agreement, a Broker may be not required to cancel the listing at the owner's request. The listing agreement may obligate the consumer monetarily after cancellation.
