Someone breaches a real estate contract when they fail to perform a duty they’re required to perform under the contract. For instance, if the buyer has 30 days to obtain financing and then on the 32nd day informs the seller that they cannot obtain the financing, they’ve breached the contract because they have not obtained the financing within the 30 day period they were allowed under the contract. When a party breaches a contract, the other party may be entitled to damages or other remedies available under the law.
