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.
Termination clauses can always be customized but standard ones are included in almost every agreement.
Simply send them a letter or email stating that you are no longer working with them effective immediately. You are not obligated to work with any realtor you don't like. Cut contact after sending the message and contact the new realtor.
The easiest way out is to sit down with the real estate brokerage the realtor works for and discuss breaking the agreement. Many reputable brokerages who wish to keep a favorable relationship with your business will agree to peaceful contract termination.
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.
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.
A federal law allows consumers to cancel contracts made with a door-to-door salesperson or anywhere other than the seller's normal place of business within three days of signing. The three-day period is called a "cooling off" period.
To cancel the contract, you must notify the seller in writing no later than midnight of the third business day after you signed the contract.
