A sum given by the buyer to the seller in connection with a contract to sell is regarded to be a deposit on account of the price, unless the parties have expressly provided otherwise.
If the parties stipulate that a sum given by the buyer to the seller is earnest money, either party may recede from the contract, but the buyer who chooses to recede must forfeit the earnest money, and the seller who so chooses must return the earnest money plus an equal amount.
When earnest money has been given and a party fails to perform for reasons other than a fortuitous event, that party will be regarded as receding from the contract.
