Bilateral Contract for Land Sale Sufficient for Transfer Without Final Deed

A contract for the sale of land was signed, but the final deed was not executed before the seller died, leading the heir to refuse to finalize the transfer despite the initial agreement. The court ruled that the preliminary sales agreement, being a bilateral contract imposing obligations on both parties, was sufficient to establish a definitive transfer of ownership upon the signing of the agreement, even without the formal execution of the final deed, and thus the heir could not unilaterally refuse to uphold the obligation.
