Part 2. Nature and Effects of Obligations. Detailed Explanations with Examples on Art. 1165 -1168.

Article 1165, first paragraph, states that if a determinate thing is to be delivered, the creditor can compel the debtor to make the delivery. It also cross-references Article 1170 which makes the debtor liable for damages if they are guilty of fraud, negligence, delay, or contravene the tenor of obligations. The creditor can file for specific performance to compel delivery.

The second paragraph of Article 1165 deals with indeterminate or generic things. In such cases, the creditor can ask for the obligation to be complied with at the expense of the debtor. This is known as substituted performance. For example, if a debtor fails to deliver 100 sacks of rice, the creditor can obtain the sacks from a third party at the debtor's expense.

The last sentence of Article 1165 discusses instances where a fortuitous event does not exempt the debtor from responsibility, specifically if the obligor delays or promises the same determinate thing to two or more persons with different interests. A fortuitous event is an unforeseen or inevitable event, often referred to as an 'act of God' (natural occurrence) or 'force majeure' (man-made). Generally, a fortuitous event can excuse a debtor, but not in these two specific cases.

The video clarifies the difference between ordinary delay (mere failure to perform on time) and legal delay (failure to perform on time which constitutes a breach, often referred to as 'in default' or 'mora'). Legal delay occurs after an extrajudicial or judicial demand is made to perform the obligation. If a fortuitous event destroys a determinate thing while the debtor is in legal delay, the debtor remains liable.

Article 1167 covers obligations 'to do' (positive personal obligations), outlining three scenarios: the debtor fails to perform, performs contrary to terms, or performs poorly. In these cases, the creditor has the right to have the obligation performed by themselves or another at the debtor's cost, and to recover damages. However, if the obligation is too personal, only damages may be claimed.

Article 1168 addresses 'negative personal obligations' or obligations 'not to do'. If the obligor does what was forbidden, it shall be undone at their expense. An example is a breach of contract where a party builds a fence in a forbidden area, which the other party can have removed at the builder's expense.

The video concludes with a summary of remedies: specific performance (performing the obligation itself, not available for 'to do' or 'not to do' obligations due to involuntary servitude concerns), equivalent performance (payment of damages, available for all obligations), and substituted performance (another party performs at the debtor's expense, applicable to obligations that are not personal).
