The two causes of action turn on whether a pre-existing contract connects the parties. Under Article 1170 of the Civil Code, a person who is guilty of fraud, negligence, or delay in performing an existing obligation — or who contravenes its tenor in any way — is liable for damages for breach of contract. Under Article 2176, when someone causes damage to another through fault or negligence, and there is no pre-existing contractual relation between them, that fault or negligence is called a quasi-delict. The distinction is not academic: it changes how long you have to sue. Under Article 1144, an action on a written contract prescribes in ten years. Under Article 1146, an action based on a quasi-delict prescribes in only four years.
Same harm, two different legal theories
It is common for a single set of facts to look, at first glance, like it could support either a breach-of-contract claim or a quasi-delict (tort) claim. A passenger injured in a bus accident has a contract of carriage with the bus company — but the driver's reckless driving also independently caused the injury through negligence. A contractor who damages a neighboring property while doing agreed-upon work has a contract with the property owner who hired them — but the physical damage caused to a third party's fence next door did not arise from any contract with that third party at all. Philippine law does not force these situations into a single box; it recognizes both categories, and which one applies (or whether both apply, to different aspects of the same facts) changes the rules that govern the case.
What breach of contract actually requires
Article 1170 of the Civil Code provides: “Those who in the performance of their obligations are guilty of fraud, negligence, or delay, and those who in any manner contravene the tenor thereof, are liable for damages.” This provision presupposes an existing obligation — typically a contract — between the parties. The liability arises because one party failed to perform what they had already bound themselves to do, whether through outright fraud, ordinary negligence in performance, delay (mora), or any other way of not honoring the agreement's actual terms. The Civil Code goes on, in Articles 1171 and 1172, to make clear that liability for fraud in performing an obligation cannot be waived in advance, and that liability for negligence in performance is likewise demandable, though courts have some latitude in regulating that liability according to the circumstances.
What quasi-delict actually requires
Article 2176 provides: “Whoever by act or omission causes damage to another, there being fault or negligence, is obliged to pay for the damage done. Such fault or negligence, if there is no pre-existing contractual relation between the parties, is called a quasi-delict.” The defining feature is right there in the text: quasi-delict is specifically the label for fault or negligence causing damage when the parties are not already bound to each other by a contract. This is the legal foundation for most everyday negligence claims that do not involve a prior agreement between the person harmed and the person at fault — a driver hitting a pedestrian, a property owner's failure to maintain safe premises injuring a visitor with no contractual relationship to them, or one stranger's careless act damaging another's property.
Article 2177 draws an additional, important line: liability for quasi-delict is entirely separate and distinct from civil liability arising from a crime under the Penal Code — meaning the existence of criminal proceedings over the same act does not by itself determine or foreclose a separate civil quasi-delict claim.
Quasi-delict liability can extend beyond the person who acted
Article 2180 extends quasi-delict liability beyond the person who directly caused the damage, to certain people responsible for them. The obligation under Article 2176 is demandable “not only for one's own acts or omissions, but also for those of persons for whom one is responsible.” The article specifically makes parents responsible for damages caused by minor children living in their company, guardians responsible for wards under their authority who live with them, and (continuing in the same article) extends similar vicarious responsibility to owners and managers of establishments for their employees, among other relationships. This is why, for example, an employer can be held civilly liable under quasi-delict principles for an employee's negligent act committed in connection with their duties, separately from any contract claim.
Why the distinction changes your deadline to file
This is where the difference stops being theoretical and starts affecting real deadlines. Article 1144 sets a ten-year prescriptive period for actions: (1) upon a written contract; (2) upon an obligation created by law; or (3) upon a judgment. Article 1145 sets a shorter six-year period for actions upon an oral contract or upon a quasi-contract. Article 1146, by contrast, gives only four years for: (1) an action upon an injury to the rights of the plaintiff; and (2) an action upon a quasi-delict.
In practice, this means the same harmful event can carry two different deadlines depending on which cause of action is pursued. If a written service contract was breached, the injured party generally has ten years to sue on that contract claim. But if the same facts are framed as a negligence (quasi-delict) claim, the window is only four years. Someone who waits past four years, assuming they can still sue because “it’s only been a few years,” may find that their quasi-delict claim has already prescribed even though a related contract claim on the same underlying transaction has not.
Choosing (or combining) the right theory
Because Philippine procedure generally allows a plaintiff to plead alternative causes of action, a case with facts that could support both theories is often framed to preserve both, where the underlying facts genuinely support each element. But the choice is not purely tactical — it depends on whether a contract actually existed between the specific parties in the specific claim being made. A passenger suing the bus company they had a ticket with is on contract ground; a bystander hit by that same bus, who never had any agreement with the bus company, can only proceed on quasi-delict grounds against it, because Article 2176's requirement of no pre-existing contractual relation is, for that plaintiff, literally true.
Given how much the applicable prescriptive period can vary — four years versus six versus ten, depending on the theory and whether a contract was written or oral — anyone who believes they have a valid claim for damages should have the facts reviewed promptly rather than assuming the longer contract-based deadline necessarily applies to every angle of the case.
Frequently Asked Questions
What is the main difference between quasi-delict and breach of contract? Breach of contract (Article 1170) applies when a party fails to properly perform an obligation under an existing contract between the parties. Quasi-delict (Article 2176) applies when fault or negligence causes damage and there is no pre-existing contractual relation between the specific parties involved.
How long do I have to file a quasi-delict (negligence) claim in the Philippines? Four years, under Civil Code Article 1146. This is shorter than the ten-year period for actions on a written contract (Article 1144) or the six-year period for an oral contract (Article 1145), which is why correctly identifying the cause of action matters.
Can an employer be sued for an employee's negligence under quasi-delict? Yes. Article 2180 extends quasi-delict liability to certain persons responsible for the person who caused the damage, including employers for their employees' negligent acts connected to their duties, separately from any contract claim that might also exist.
If someone is also facing a criminal case for the same act, does that affect a separate quasi-delict claim? No. Article 2177 makes quasi-delict liability entirely separate and distinct from civil liability arising from a crime under the Penal Code. A pending or resolved criminal case does not by itself determine a separate civil quasi-delict claim.
