CE Laws – Civil Code on Obligations & Contracts: Comprehensive Bullet‐Point Notes
Enumerate core concepts on contracts & obligations.
Apply these rules as bases for professional civil-engineering practice.
Obligation: Definition & Elements
Etymology: Latin "obligatio" = "to tie/bind".
Legal definition: A juridical necessity whereby one (debtor) is bound in favor of another (creditor) to give, to do, or not to do something; courts may compel fulfillment or equivalent economic value.
4 Essential elements (Mnemonic: APOJ):
Active Subject – Creditor / Obligee (holder of the right).
Passive Subject – Debtor / Obligor (bears the duty).
Object / Prestation – Conduct required: give, do, or not do.
Juridical / Legal Tie (Vinculum Juris) – Cause that binds the parties; traceable to the source of the obligation.
Civil vs. Natural Obligations
Civil: enforceable in court.
Natural: based on equity/natural law; no court action, but voluntary fulfillment is irrevocable.
Form: oral, written, or partly both.
Classification by Subject-Matter
Real Obligation – to give (deliver a determinate or generic thing).
Personal Obligation – to do (positive) or not do (negative).
Positive personal = rendering a service.
Negative personal = refraining from an act ("obligation not to give").
Sources of Obligations (Art. )
Law – imposed by statutes; never presumed.
Contracts – arise from parties’ valid agreements; have force of law between parties; must not contravene law, morals, good customs, public order, or public policy; must be complied with in good faith.
Quasi-Contracts – lawful, voluntary, unilateral acts that prevent unjust enrichment.
a. Negotiorum Gestio – voluntary management of another’s property/affairs w/out authority.
b. Solutio Indebiti – delivery/ payment by mistake of something not owed.
Acts or Omissions Punished by Law (Delicts) – civil liability arising from criminal acts (governed by Revised Penal Code & Civil Code).
Quasi-Delicts (Torts) – damage due to fault/negligence without pre-existing contract.
Requisites: act/omission, fault/negligence, damage, causal connection, no contractual relation.
Care & Preservation Duties in Real Obligations
Debtor must care for determinate thing with diligence of a good father of a family (ordinary diligence) unless law or stipulation sets a different standard.
Liability for loss generally excused by fortuitous event unless:
Debtor in delay.
Law or stipulation says otherwise.
Obligation requires assumption of risk.
Fruits (natural, industrial, civil) accrue to creditor from time the obligation to deliver arises.
Remedies of Creditor upon Breach
Action for Performance
Specific performance or performance by third person at debtor’s expense.
Action for Damages
May be demanded with performance or with rescission.
Rescission (Resolution) under Art.
Choice between fulfillment or rescission + damages; choice is alternative & indivisible.
Delay (Mora)
Ordinary delay – failure to perform on time.
Legal delay (Default/Mora) – failure constituting breach; arises when:
Obligation is demandable.
Creditor issues judicial or extrajudicial demand.
Debtor fails to comply.
Kinds:
Mora Solvendi – debtor’s default.
Mora Accipiendi – creditor’s delay in accepting.
Compensatio Morae – reciprocal obligations; both parties in delay.
Demand not required when:
Obligation/law designates time essential.
Time is of the essence by nature.
Demand would be useless.
Debtor expressly waived demand.
Liability for Damages – 4 Sources
Fraud (Dolo) – intentional deception.
Negligence (Culpa) – omission of required diligence.
Delay (Mora) – see above.
Contravention of Tenor – violation of terms/defective performance.
Fortuitous Event (Caso Fortuito)
Event impossible to foresee or inevitable even if foreseen; exempts debtor unless:
Express stipulation / law imposes liability.
Debtor already in delay.
Nature of obligation involves assumption of risk.
Miscellaneous Performance Rules
Delivery of determinate thing includes accessories & accessions even if not mentioned.
If debtor does/omits contrary to obligation to do/not do, creditor may have it undone at debtor’s expense.
Pure obligations (no condition/period) – demandable at once.
Conditional obligations – effect depends on uncertain future/past unknown event.
Obligations with a Period (Day Certain) – demandable when period arrives; obligations take effect immediately but terminate on day certain.
Alternative obligations – debtor must completely perform one prestation; creditor can’t be forced to accept mix.
Joint vs. Solidary Obligations:
Presumption is joint; solidarity only when express, by law, or nature.
Penal Clause – penalty substitutes indemnity/interest unless contrary stipulation; still liable for fraud or refusal to pay penalty.
Payment & Extinguishment
Payment = delivery of money or performance of prestation.
Application of Payment (Art. ): debtor with several similar debts may designate which one is paid at payment time; rules:
Cannot apply to debts not yet due (unless agreed).
Acceptance of receipt with application bars debtor from protesting.
Dation in Payment (Dación en Pago) – debtor assigns property to creditors; releases up to net proceeds unless agreed otherwise.
Consignation – deposit of thing/sum with court when creditor unjustly refuses to accept.
Loss of Determinate Thing without debtor’s fault & before delay extinguishes obligation; exceptions noted earlier.
Condonation / Remission – creditor’s gratuitous waiver; needs debtor’s acceptance; may be express or implied.
Confusion / Merger – creditor and debtor become same person ⇒ obligation extinguished.
Compensation – parties mutually debtor & creditor extinguish to concurrent amount.
Novation – modifies obligation by (a) changing object/principal terms, (b) substituting debtor, or (c) subrogating third person as creditor.
Contracts – Definition & Three Stages
Contract: Meeting of minds between two persons whereby one binds himself to give something or render some service.
3 Stages (Consent-Perfection-Consummation framework):
Conception / Generation – preliminary negotiations; ends at agreement.
Perfection / Birth – meeting of minds on object & cause; contract becomes binding.
Consummation / Fulfillment – performance, leading to termination when obligations complete.
Freedom to Stipulate
Parties may set any terms not contrary to law, morals, good customs, public order, public policy.
Essential Requisites (Art. )
Consent – manifested by offer and absolute acceptance.
Offer must be certain; acceptance must be unqualified (qualified ⇒ counter-offer).
Acceptance by letter/telegram binds offeror when knowledge reaches him; place of contract = where offer was made.
Object Certain – determinable subject-matter; may be future thing.
Cause / Consideration – essential, licit, and true reason obligating party.
Form & Proof of Contracts
General rule: binding regardless of form if requisites present.
Exception: Law requires special form for validity, enforceability (Statute of Frauds), or proof; parties may compel each other to observe form after perfection.
Reformation vs. Annulment
Reformation – instrument fails to express true intention due to mistake, fraud, inequitable conduct, or accident after meeting of minds.
Annulment – vitiated consent prevented meeting of minds.
Cardinal interpretation rule: clear terms control; words presumed in their primary/general meaning; extrinsic evidence allowed if terms ambiguous/technical/local sense proven.
Defective Contracts
Rescissible – valid but rescinded due to lesion/damage to party or third persons (e.g., contracts by guardian causing > lesion).
Voidable / Voidable (Nullable) – valid until annulled; defects = incapacity or vitiated consent (mistake, violence, intimidation, undue influence, fraud); susceptible of ratification.
Unenforceable – cannot be sued upon unless ratified.
Acts without authority or beyond power.
Those covered by Statute of Frauds (sale of land >, representation of debt, marriage settlement, longer-than-1-year services, etc.) lacking written memorandum.
Void / Inexistent – produce no effect; cannot be ratified.
Illicit object/cause (contrary to law, morals, customs, public order/policy).
Absolutely simulated/fictitious.
Object/cause did not exist or is outside commerce of men.
Impossible service; indeterminable principal object.
Expressly prohibited or declared void by law.
Defense of illegality cannot be waived.
Practical & Professional Connections for Civil Engineers
Contract drafting: ensure clear description of works (object), proper consideration, lawful purpose to avoid void or voidable status.
Project delays: understand mora concepts for liquidated damages, extensions, or rescission.
Quasi-contracts: site manager taking emergency measures to protect adjacent property may later claim reimbursement under negotiorum gestio.
Tort liability: defective design or negligent supervision can give rise to quasi-delict claims even without contract with injured third party.
Fortuitous events (e.g., typhoons, earthquakes) & force-majeure clauses must align with statutory definitions to validly excuse performance.
Solidary vs. joint obligations: joint-venture partners liable only pro-rata unless contract/law says otherwise; critical in surety arrangements.
Penal clauses: common in construction contracts as liquidated damages; know that proof of actual loss unnecessary unless clause deemed iniquitous.
Ethical & Philosophical Implications
Emphasis on good faith in compliance and negotiation.
Equity & unjust enrichment doctrines (quasi-contracts) reflect moral expectation of fairness.
Natural obligations honor moral duties beyond legal enforceability – aligning professional ethics with jurisprudence.
