Seller Refuses Down Payment After Final Deed Execution

A party entered into a contract to purchase land with a promise to remit the price in installments upon signing a final deed, but after the final deed was signed, the seller refused to remit the stipulated down payment, arguing the contract was void due to a purported prior agreement that modified the payment terms, a claim the buyer opposed by asserting that the final deed represented the complete and definitive agreement. The court ruled that the final deed, as a bilateral agreement concluded between the parties, superseded any prior arrangements regarding payment terms, and therefore, the seller was definitively obligated to remit the down payment as stipulated therein, leading to the dismissal of the seller's appeal.
