Article 1163. Every person obliged to give something is also obliged to take care of it with the proper diligence of a good father of a family, unless the law or the stipulation of the parties requires another standard of care. (1094a)
Article 1164. The creditor has a right to the fruits of the thing from the time the obligation to deliver it arises. However, he shall acquire no real right over it until the same has been delivered to him. (1095)
Article 1165. When what is to be delivered is a determinate thing, the creditor, in addition to the right granted him by article 1170, may compel the debtor to make the delivery.
If the thing is indeterminate or generic, he may ask that the obligation be complied with at the expense of the debtor.
If the obligor delays, or has promised to deliver the same thing to two or more persons who do not have the same interest, he shall be responsible for any fortuitous event until he has effected the delivery. (1096)
Article 1262. An obligation which consists in the delivery of a determinate thing shall be extinguished if it should be lost or destroyed without the fault of the debtor, and before he has incurred in delay.
When by law or stipulation, the obligor is liable even for fortuitous events, the loss of the thing does not extinguish the obligation, and he shall be responsible for damages. The same rule applies when the nature of the obligation requires the assumption of risk. (1182a)
