Summary of "Obligations 6: Pure & Conditional Obligations"

Main ideas and concepts (Pure & Conditional Obligations)

1) Types of obligations: Pure vs. Conditional

Pure (unconditional) obligation
- Has no condition and no specific date for fulfillment.
- Effect: The creditor may demand performance immediately/at once.
Conditional obligation
- Depends on a condition (a future and uncertain event).
- Effect of the condition:
  - If the condition happens: it creates rights or extinguishes rights already acquired (depending on the kind of condition).
  - If it does not happen: the obligation fails to come into existence or remains ineffective.

2) Definition: Condition vs. Period

Condition: future and uncertain event; may create rights or extinguish acquired rights.
Period: future and certain event/date.

Example contrast:

Death (certain) → treated like a period.
Death due to a specific cause (e.g., “dies of coronavirus”) is uncertain → treated like a condition.

3) Rule distinguishing “means enable/permit” from period vs. condition

If X binds himself to pay when his means enable/permit him:

It is treated as a period, not a condition.
The uncertainty is only the duration (when his means will permit), not whether the event will exist.

Remedy / procedure mentioned

Article 1197 (as cited by the speaker):
- The creditor may ask the court to set a period for compliance.
- After the court sets the period:
  - The creditor can sue/collect only after demand is made and the debtor fails to pay.

Potestative (potestate) conditions: types and validity

A) Simple/positive potestative conditions (from one party plus external act)

Generally described as valid when structured as “will of one party + some other external act”.

B) Purely potestative conditions (dependent solely on one party’s will)

Core rule given:

If the condition depends solely on the will of the debtor, the obligation is void.
Reason: performance/validity is left entirely to the debtor’s choice, so it cannot be demanded.

Valid case for potestative condition depends on which party:

If the condition depends solely on the creditor’s will:
- The obligation is valid, because the creditor is interested in fulfillment and can enforce it (framed as obligation “on demand of the creditor”).

C) Resolutory vs suspensory effect (brief positioning)

When the potestative condition is of a type that extinguishes rights (resolutory context), the treatment differs (speaker indicates more to follow later).

D) Casual condition

Casual condition: depends on chance or the will of a third party.
Effect: stated as valid.

E) Mixed condition

Mixed condition: depends partly on one party’s will and partly on chance/third party will.
Effect: stated as valid, but both elements must be complied with.

Example given:

X promises payment of 500 as soon as he receives funds from the sale of his house in Makati:
- Labeled a mixed condition (partly debtor-related and partly dependent on external sale factors).

Example of potestative-only “sole will of debtor” leading to void:

If the promise is “as soon as he decides to sell” (solely his choice):
- Labeled purely potestative → void (creditor cannot demand because debtor can simply refuse).

“Purely potestative condition void” vs. pre-existing obligation

General rule stated:
- Potestative condition dependent solely on the debtor’s will → void.
But if the underlying obligation is already pre-existing:
- the condition is void while the obligation remains valid.
- The speaker suggests it can be treated like a period, and courts may be asked to set one unless parties agree.

Suspensive vs. Resolutory conditions (major distinction)

A) Suspensive condition (rights arise only upon happening)

When it happens: rights arise.
Before it happens:
- demandability/performance is held in suspense (creditor generally cannot demand performance).
- creditor may take protective actions, such as:
  - preventing debtor from transferring/concealing the thing, and/or
  - annotating the claim on the title (as described).
If debtor already paid by mistake before the condition occurs:
- debtor may recover under solutio indebiti.
After it happens: creditor can demand performance; debtor can be compelled.

B) Resolutory condition (rights are extinguished upon happening)

When it happens: acquired rights are extinguished.
Effect after happening: parties must do mutual restitution (return what they received).
If condition does not happen: rights consolidate and become absolute.

Retroactive effects (for conditional obligations to give vs other types)

Obligation to give

Conditional effects are said to be retroactive to the date the parties first constituted the obligation.
Rights of action counted from that day (as stated).

Exceptions to retroactivity

Retroactivity does not apply in:

Real contracts (perfected by delivery)
- Since rights arise only upon delivery, nothing is retroactively pulled back beyond delivery.
Successive/in intervals performance
- e.g., lease paid monthly → no retroactive effect.

Personal obligations (to do or not to do)

Speaker’s rule:
- Courts determine whether there is retroactive effect and what it is.

Reciprocal obligations

If things bear fruits and price bears interests:
- treated as mutually compensated/set-off to avoid mutual accounting.

Unilateral obligations

Generally no retroactive effect.
One party may retain fruits until delivery, unless the parties stipulate otherwise.

Conditions fixed to determinate time: positive vs. negative (timing rules)

Positive condition: must happen by a determinate time

If event happens before/at the time → obligation becomes effective.
If event does not happen and the time expires → obligation extinguished.
If it becomes certain the event cannot occur before the time expires → obligation still extinguished.

Example used:

Pay 10,000 if B marries C before B reaches age 23:
- marries at 21 → X liable
- marries at 24+ → X not liable
- if C dies while B is 20 → X not liable (impossible for C to marry)

Negative condition: must NOT happen by a determinate time

If event occurs on/before the time → obligation not effective.
If time passes and event did not happen → obligation becomes effective.
If it becomes certain the event cannot occur → obligation becomes effective.

Example used:

Pay 10,000 if B is not yet married to C by Dec 30:
- marries on or before Dec 30 → X not liable
- still not married after Dec 30 (e.g., Dec 31) → X liable
- if C dies (marriage cannot occur) before Dec 30 → X liable

Doctrine of constructive fulfillment

Under this doctrine, a condition is deemed fulfilled if:
1. The condition must be possible.
2. The debtor actually prevents fulfillment.
3. The debtor’s act is voluntary.
Effect: the obligation becomes pure and becomes demandable by the creditor.

Loss, impairment, improvement, or deterioration of the thing

Applies only under specific conditions (as stated).

Scope/requirements (as mentioned)

Applies only if:

It’s a real obligation to give,
involving a determinate thing (physically segregated/identified),
under a suspensive condition already fulfilled,
and loss/deterioration/improvement occurs while the condition is still pending (before happening).

Rules given

Loss
- Lost without debtor fault → obligation extinguished.
- Lost due to debtor fault → debtor liable for damages.
Deterioration
- Deterioration without debtor fault: creditor bears impairment.
- Deterioration due to debtor fault:
  - creditor may choose rescission (recession) or specific performance with damages.
  - creditor may still want the thing even if deteriorated (per speaker).
Improvement
- Improvement due to nature of the thing or passage of time: benefits the creditor.
- Improvement due to debtor’s expense: debtor gets a right described as luxury/expenses (speaker references another concept and points to a prior episode).

Resolutory vs suspensive recap and final classification

Pure obligations and obligations subject to a suspensive/resolutory period or condition are described as those where the obligation is immediately demandable, “subject to threat of extinction upon happening of the condition” (speaker’s wrap-up wording).

Impossible conditions

Types of impossibility

Physical impossibility: cannot be done.
Legal impossibility: contrary to law, morals, customs, public policy/public order.

General rule

If the obligation is subject to an impossible condition:
- the obligation is void.
The impossibility must exist at the time of creation.

Exception / nuance: when there is also a period

Speaker says:
- An impossible event with a time period for performance can be treated as valid (because feasibility might exist during the period).
- Without a period, “ridiculous” events imply perverse intent to avoid performance.

Additional “negative condition” handling

Example:
- “Pay 500 if you do not sprout wings and fly.”
Treatment described:
- the condition is disregarded and obligation treated as pure because the “impossible” aspect is framed negatively.

Pre-existing obligation exception

If there is a pre-existing obligation and later payment is conditioned on something impossible:
- only the impossible condition is disregarded,
- the underlying obligation remains valid (speaker’s statement),
- payment may be treated as unconditional/pured (speaker phrasing somewhat inconsistent, but takeaway: pre-existing debt prevents voiding the entire obligation).

Divisible obligation exception

If the obligation is divisible:
- only the part subject to the impossible condition is void;
- the rest remains valid.
