32.2 Kinds of Obligations

Kinds of Obligations

Obligations are classified by the presence of conditions or periods, the number of objects and parties, divisibility, and penal clauses. This section covers pure, conditional, and period obligations, alternative and facultative obligations, joint and solidary obligations, divisible and indivisible obligations, and obligations with a penal clause, with a worked problem on solidary debtors.

1. Kinds of Obligations

Pure and Conditional Obligations (Articles 1179 to 1192)

• Pure Obligation: Its fulfillment does not depend upon a condition or a period. It is demandable at once (Article 1179).
• Conditional Obligation: An obligation whose efficacy depends upon the fulfillment or non-fulfillment of a future and uncertain event, or upon a past event unknown to the parties.
  • Suspensive Condition (Condition Precedent): The happening of the condition gives rise to the obligation. Prior to fulfillment, the creditor has an expectancy right.
  • Resolutory Condition (Condition Subsequent): The happening of the condition immediately extinguishes the obligation and restores the parties to their status quo.

Potestative Conditions (Article 1182)

A condition is potestative when its fulfillment depends upon the sole will of one of the contracting parties:

                               Potestative Conditions (Article 1182)
                                                │
         ┌──────────────────────────────────────┴──────────────────────────────────────┐
         ▼                                                                             ▼
Suspensive Potestative Condition                                              Resolutory Potestative Condition
• Sole will of DEBTOR: BOTH condition and obligation are VOID!               • Sole will of DEBTOR: VALID (e.g., right of repurchase)
• Sole will of CREDITOR: Entirely VALID (promissory note payable on demand)   • Sole will of CREDITOR: VALID

• Casual Condition: Depends upon chance or the will of a third person (VALID).
• Mixed Condition: Depends partly upon the will of a party and partly upon chance or a third person (VALID).

Obligations with a Period (Articles 1193 to 1198)

A period consists of a day certain which must necessarily come, although it may not be known when. If the uncertainty consists in whether the day will come or not, the obligation is conditional.

• Benefit of the Period (Article 1196): Whenever in an obligation a period is designated, it is presumed to have been established for the benefit of both the creditor and the debtor, unless from the tenor of the same or other circumstances it should appear that the period has been established in favor of one or the other. If for the benefit of both, the creditor cannot demand payment before the due date, nor can the debtor compel the creditor to accept premature payment.
• Loss of Right to Make Use of the Period (Article 1198): The obligation becomes immediately demandable as if it were a pure obligation when the debtor:
  1. Becomes insolvent, unless he gives a guaranty or security for the debt;
  2. Fails to furnish the guaranties or securities which he promised;
  3. Impairs said guaranties or securities by his own acts, or when through a fortuitous event they disappear, unless he immediately gives new ones equally satisfactory;
  4. Violates any undertaking in consideration of which the creditor agreed to the period;
  5. Attempts to abscond.

Alternative and Facultative Obligations (Articles 1199 to 1206)

Joint and Solidary Obligations (Articles 1207 to 1222)

The Presumption of Joint Obligation

Under Article 1207 and 1208, an obligation involving two or more debtors or creditors is presumed to be JOINT (Mancomunada). Solidarity exists only when:

1. The obligation expressly so stipulates (using words like solidary, in solidum, jointly and severally, individually and collectively);
2. The law expressly mandates solidarity (e.g., liability of partners for torts under Art. 1822; liability of directors for unlawful acts under Revised Corporation Code Sec. 30); or
3. The nature of the obligation requires solidarity.

Operational Mechanics

• Joint Obligations (Mancomunada): The credit or debt is divided into as many equal shares as there are creditors or debtors. Each debtor is liable only for their proportionate share, and each creditor can collect only their proportionate share. The insolvency of one joint debtor does not burden the others.
• Solidary Obligations (In Solidum): Each creditor has the right to demand, and each debtor is bound to render, entire compliance with the prestation.
  • Passive Solidarity (Solidary Debtors): The creditor may proceed against any one of the solidary debtors or some or all of them simultaneously (Article 1216). Payment made by one solidary debtor extinguishes the obligation (Article 1217).
  • Right of Reimbursement: The paying solidary debtor can demand reimbursement from co-debtors only for their respective proportionate shares, plus interest from the date of payment. If one co-debtor is insolvent, their share is borne proportionally by all the other co-debtors, including the paying debtor.

$\text{Reimbursement per Solvent Co-Debtor} = \text{Their Base Share} + \left(\frac{\text{Insolvent Debtor's Share}}{\text{Number of Remaining Solvent Debtors}}\right)$

Defenses Available to a Solidary Debtor (Article 1222)

A solidary debtor sued by the creditor may plead three types of defenses:

1. Defenses derived from the nature of the obligation (Complete Defense): Total nullity, prescription, illegality, or prior payment. Exonerates all solidary debtors completely.
2. Defenses personal to the debtor sued (Complete Defense for that debtor): Minority, insanity, or vitiated consent of the defendant debtor. Exonerates that specific debtor completely.
3. Defenses personal to co-debtors (Partial Defense): Minority or incapacity of a co-debtor. Operates as a defense only to the extent of that specific co-debtor's proportionate share in the debt.

2. Worked Problem: Solidary Debtors and Insolvency Allocation

Scenario: Alvin, Brenda, and Carlos are solidary debtors bound to pay Diana the sum of PHP 900,000 on October 1, 2026. On the due date, Diana files an action against Alvin for the entire amount of PHP 900,000. Alvin pays the full PHP 900,000 to Diana. When Alvin seeks reimbursement from Brenda and Carlos, it is judicially established that Carlos is completely insolvent and has zero assets. How much can Alvin collect from Brenda?

Analysis and Computation:

1. Base Internal Shares: In the absence of contrary stipulation, the internal liability among solidary debtors is equal: $\text{PHP }900{,}000 / 3 = \text{PHP }300{,}000$ per debtor.
2. Effect of Payment to Creditor: Alvin's payment of PHP 900,000 extinguished the debt with respect to Diana pursuant to Article 1217.
3. Insolvency Rule under Article 1217 par. 3: The share of the insolvent debtor (Carlos's PHP 300,000) must be borne proportionately by all the other co-debtors, including the debtor who made the payment.
4. Allocation of Carlos's Insolvency:
   • Solvent debtors: Alvin and Brenda (2 equal shares).
   • Insolvent debtor's share absorbed: $\text{PHP }300{,}000 / 2 = \text{PHP }150{,}000$ each.
5. Total Claim of Alvin against Brenda:

$$\begin{aligned} \text{Brenda's Share} &= \text{Base Share } (\text{PHP }300{,}000) + \text{Share of Carlos's Insolvency } (\text{PHP }150{,}000) \\ &= \text{PHP }450{,}000 \end{aligned}$$

Alvin bears the remaining PHP 450,000 himself (PHP 300,000 base + PHP 150,000 insolvency share).
