Law on Obligations- Chapter 2

Article 1163 dictates that anyone obligated to give something must take care of it with the 'proper diligence of a good father of a family,' unless the law or agreement specifies a different standard. This default standard can be dispensed with, or a higher standard can be required by agreement or by law (e.g., extraordinary diligence in contracts of carriage).

Understanding the difference between specific (determinate) and generic (indeterminate) things is crucial for determining liability in case of loss. A specific thing is uniquely identified, while a generic thing belongs to a class and cannot be pointed out with particularity (e.g., specific: 'the ballpen I am holding'; generic: 'a red Toyota car'). Generic things do not perish, meaning the obligation to deliver them remains even if some are lost due to a fortuitous event.

For a determinate thing, the debtor's duties include preserving it with due diligence, delivering its fruits, accessions, and accessories, delivering the thing itself, and answering for damages in case of breach. For a generic thing, the debtor must deliver an item of the quality intended by the parties and is liable for fraud, negligence, or delay. Fruits are categorized as natural (without human labor), industrial (by cultivation or labor), and civil (derived from juridical relations, like rents).

A personal right is the creditor's right to demand performance from a specific debtor, binding only against that person. A real right, on the other hand, is an interest over a specific thing, enforceable against the whole world (e.g., ownership, possession, mortgage). The video emphasizes the distinction, stating that personal rights are against specific individuals, while real rights are against everyone.

In specific real obligations, remedies include demanding specific performance with damages, or rescission/cancellation with damages, or damages only. For generic real obligations, the creditor can demand specific performance, rescission, or have a third person perform at the debtor's expense. Accessions are fruits or improvements to a thing (e.g., a house on land), while accessories are things joined to or included with the principal for embellishment or completion (e.g., a key to a house). All accessions and accessories are considered included in the obligation to deliver a determinate thing.

If a person fails to perform an obligation to do, or performs it poorly or contrary to the agreement, it shall be executed at their cost, and poorly done work may be undone. The court cannot compel specific performance in personal obligations, as this would amount to involuntary servitude, which is prohibited by the Philippine Constitution (Article III, Section 18). Remedies in a positive personal obligation include having the obligation performed by others at the debtor's expense or seeking damages. In negative personal obligations, the forbidden act can be undone with damages at the debtor's cost.

Ordinary delay is simply failing to perform on time, while legal delay (mora, default) is a failure to perform on time that constitutes a breach. The general rule is 'no demand, no delay' – a formal demand from the creditor is usually required. Kinds of delay include mora solvendi (debtor's delay), mora accipiendi (creditor's delay), and compensatio morae (delay in reciprocal obligations). Requisites for debtor's delay are failure to perform on the agreed date, a demand from the creditor, and the obligation being due and demandable.

In mora solvendi, the debtor is liable for damages (interest for money obligations) from the date of demand and even for fortuitous events if in delay with a determinate thing. In mora accipiendi, the creditor is liable for damages, bears the risk of loss, and the debtor may be released by consignation. In compensatio morae (reciprocal obligations), there is no actionable default if both parties are in delay, and delay of one cancels the delay of the other.

Demand is not necessary when the obligation expressly states it, when the law provides for it (e.g., taxes), when time is of the essence (e.g., wedding gown delivery), when demand would be useless (e.g., object lost due to debtor's negligence, or due to a fortuitous event for which debtor is still liable, or prior refusal to perform), or when a party in a reciprocal obligation performs or is ready to perform their part.

The video details four grounds for liability for damages: fraud, negligence, delay, and contravention of the obligation's tenor. Fraud (dolo) involves intentional evasion or malice; a waiver for future fraud is void. There are two kinds of fraud: causal fraud (dolo causante) which vitiates consent and allows for contract annulment, and incidental fraud (dolo incidente) which occurs during performance and only entitles to damages. Negligence lacks intentional injury and can be culpa contractual (contractual), culpa aquiliana (civil), or culpa criminal (criminal). Waiver of future negligence is generally valid, except when extraordinary diligence is required (e.g., common carriers).

A fortuitous event is an unforeseeable or inevitable occurrence (e.g., acts of man like war, or acts of God like earthquakes) that makes fulfilling an obligation impossible. For a fortuitous event to exempt the debtor from liability, it must be independent of human will, unforeseeable/inevitable, render compliance impossible, and the debtor must not have contributed to the injury. Exceptions where the debtor is still liable despite a fortuitous event include when provided by law (e.g., fraud, negligence, delay), when delivering the same specific thing to multiple people, when the obligation arises from a crime, when the thing is generic, and when stipulated by the parties or the nature of the obligation requires assumption of risk (e.g., insurance).
