There are two ways within which you can "cancel" the listing of your house . . .. a conditional and an unconditional withdrawal (at least these are the options here in Monmouth/Ocean County).
The conditional withdrawal is designed to protect the real estate company from sellers who may be negotiating direct with a buyer and wishing to avoid the commissions despite the marketing efforts (and monies spent) of the listing company that may have produced the buyers. Most often the original listing contract will hold a seller liable for 30 days to 6 months after the original listing date for commissions due (the depends on the specifics of the contract) should the property be shown to the buyer by either the listing agent or a buyers agent while active. Again, in place to protect those of us who invest oodles of time and energy in procuring a sale.
An unconditional withdrawal with most agencies is more difficult to acquire as this releases the realtors from future commission liability.
