Seller's Performance Not Condition Precedent to Buyer's Obligation to Complete Property Sale

A contract for the sale of property was executed, requiring the buyer to pay a portion of the price upon signing and the remainder upon completion of administrative formalities, but the buyer subsequently refused to sign the final deed, arguing the seller had not performed all required preliminary actions. The court rejected the buyer's appeal, reasoning that the administrative formalities were not conditions precedent to the buyer's obligation to complete the sale, but rather obligations resting on the seller that, even if unfulfilled, did not legally justify the buyer's unilateral refusal to proceed with the final formal act of transfer required under the initial agreement.
