What is the judicial principle regarding the seller's obligation to transfer the title of the sold property after receiving the full price, and what is the court's position on claims for attorney's fees in such lawsuits?

The judicial circuit rules to obligate the seller to transfer the title of the sold property to the buyer, provided the seller is the rightful owner and has received the full price of the sold property, as the transfer of title is considered one of his fundamental duties. As for the claim for attorney's fees, it is rejected due to the failure to provide sufficient evidence of actually incurring them.
