Quick answer

There is no single prescriptive period for every Philippine legal case. To determine the deadline, identify the exact civil cause of action or criminal offense, find the law that specifically governs it, establish when the cause of action accrued or the offense was committed or discovered, account for every valid interruption or suspension, and then compute the remaining period under the applicable rules.

Always check a special law before relying on the Civil Code or Revised Penal Code. The same facts may support several claims with different deadlines. Use the earliest legally plausible starting date and file well before the calculated deadline; negotiations, police reports, barangay proceedings, administrative complaints, and demand letters do not automatically stop every prescriptive period.

Why the legal classification matters

Prescription is the loss of the right to sue, prosecute, or enforce a remedy because the period fixed by law has expired. It is different from:

A procedural deadline, such as the period to appeal or seek reconsideration;
A contractual notice requirement;
A mandatory preliminary step, such as barangay conciliation or labor conciliation;
Laches, which concerns unreasonable and prejudicial delay and has no single fixed period; and
Prescription of a penalty after final conviction, which is distinct from prescription of the offense itself.

Do not classify a case solely by its everyday description. A “car accident case,” for example, might be a four-year quasi-delict claim, a ten-year action based on a written contract of carriage, a criminal prosecution, or several legally distinct claims. Courts generally determine the applicable period from the allegations, legal duty violated, and relief sought—not merely the title placed on the complaint.

A five-step method for calculating the deadline

1. Identify every possible claim or offense

Write down:

What happened;
Who violated whose right;
The legal duty allegedly breached;
The remedy sought—payment, damages, recovery of property, possession, annulment, reinstatement, prosecution, or another form of relief; and
Whether the claim arises from a contract, statute, crime, property right, employment relationship, family relationship, or administrative decision.

Analyze each claim separately. A complaint may contain one timely cause of action and another that has already prescribed.

For a criminal matter, identify the exact offense and the law penalizing it. Do not calculate prescription from a generic description such as “fraud,” “harassment,” or “cybercrime.”

2. Find the controlling law in the proper order

Check sources in this order:

The statute creating the right, remedy, or offense;
Its amendments and implementing regulations;
Special procedural rules governing the forum;
Controlling Supreme Court decisions interpreting the period;
Only then, the default provisions of the Civil Code, Revised Penal Code, or Act No. 3326.

A special law may provide its own period, starting point, filing method, or tolling rule. Those specific provisions ordinarily control over general rules.

Also confirm which version of the law applies. Amendments may change the offense, prescribed penalty, remedy, or prescriptive period. Criminal-law amendments favorable to an accused may raise retroactivity issues that require case-specific analysis.

3. Determine when the period began

For civil actions, the general rule is that prescription runs from the day the action may legally be brought. A cause of action ordinarily accrues when all three are present:

A legal right belonging to the claimant;
A corresponding duty on the other party; and
An act or omission violating that right.

The starting date may therefore be:

The maturity date of a loan;
The due date of each unpaid installment;
The date of breach;
The date a demand required by law or contract was received;
The date possession was unlawfully withheld;
The date employment ended;
The date an assessment or final decision was received; or
A date of discovery, but only when the applicable law or controlling doctrine authorizes a discovery rule.

Do not assume that making a demand postpones accrual. In some obligations, demand is needed before a cause of action exists; in others, the right to sue arose earlier. For installment obligations, each missed installment may have its own accrual date, while a valid acceleration clause may change the analysis.

For crimes under the Revised Penal Code, Article 91 generally counts from discovery by the offended party, the authorities, or their agents. Under special penal laws, Act No. 3326 generally counts from commission, or from discovery when the violation was not known at the time. The special law may prescribe a different rule.

4. Identify every interruption, suspension, or excluded period

These concepts are not interchangeable:

Interruption may erase elapsed time and cause a new period to begin.
Suspension or tolling generally pauses the clock and preserves the unused balance.
An excluded period is not counted at all.

The effect depends on the particular statute and jurisprudence. Prepare a timeline showing:

Event	Possible legal effect	Supporting document
Right accrued or offense occurred	Clock may begin	Contract, notice, incident record
Claim or offense discovered	Possible alternative starting point	Email, audit report, affidavit
Written demand received	Possible civil interruption	Demand and proof of receipt
Barangay complaint filed	Limited statutory interruption	Barangay-stamped complaint
Prosecutor’s complaint filed	Possible criminal interruption	Docket stamp or official receipt
Case dismissed or proceedings ended	Clock may resume or restart	Final order and proof of receipt
Intended filing date	Must be before the valid deadline	Court or agency requirements

5. File the correct initiating document in the correct forum

A letter, blotter entry, consultation, settlement proposal, or complaint sent to the wrong office may not constitute legal filing.

Before the deadline, confirm:

The court, prosecutor, tribunal, or agency with jurisdiction;
Venue;
Whether barangay conciliation, SEnA, administrative review, or another condition precedent applies;
The required complaint, petition, information, or request for assistance;
Verification, certification against forum shopping, affidavits, annexes, and service requirements;
Filing fees and when they must be paid; and
The currently authorized paper or electronic filing method.

Keep the stamped receiving copy, electronic acknowledgment, docket number, payment receipt, and proof of service. A document merely drafted or emailed through an unauthorized channel is not necessarily filed.

Common prescriptive periods for civil actions

The following are general Civil Code periods. A special law, a more specific Civil Code provision, the nature of the remedy, or controlling jurisprudence may produce a different result.

Type of civil action	General period
Recovery of movable property	8 years from loss of possession, subject to applicable acquisitive-prescription rules
Real action over immovable property	30 years
Foreclosure or other mortgage action	10 years
Written contract	10 years from accrual
Obligation created by law	10 years from accrual
Action upon a judgment	10 years from accrual
Oral contract	6 years
Quasi-contract, such as certain claims for payment made by mistake	6 years
Injury to the plaintiff’s rights	4 years
Quasi-delict	4 years
Forcible entry or unlawful detainer	1 year under the applicable ejectment rules
Civil action for defamation	1 year
Action without another period fixed by law	5 years

These periods appear in Articles 1140 to 1150 of the Civil Code.

Important civil-law qualifications

Ejectment: The one-year period does not mean every possessory remedy disappears after one year. Depending on the facts, an ordinary action to recover the right to possess may remain available. The starting point also differs between forcible entry and unlawful detainer and may depend on discovery, expiration of the right to possess, or the last valid demand to vacate.

Judgments: Although the Civil Code provides a ten-year period for actions upon judgments, Rule 39, Section 6 generally allows execution by motion only within five years from entry. Afterward, and before the judgment becomes barred, an independent action to enforce or revive it is ordinarily required. Do not wait for the ten-year point.

Registered land: Section 47 of the Property Registration Decree states that title to registered land cannot be acquired against the registered owner through prescription or adverse possession. That does not make every related action automatically imprescriptible. Personal actions involving fraud, contracts, trusts, damages, reconveyance, or particular transactions may still have deadlines. The Supreme Court has expressly distinguished protection from acquisitive prescription from the possible extinctive prescription of a related action. See P.D. No. 1529, Section 47.

Void marriages: An action or defense for declaration of absolute nullity of a void marriage does not prescribe under Article 39 of the Family Code, as amended by Republic Act No. 8533. This does not eliminate standing, pleading, evidence, and procedural requirements.

Labor claims: Article 306 of the Labor Code generally gives employees three years from accrual for money claims arising from employer-employee relations. An illegal-dismissal claim is generally treated as an injury to rights and prescribes in four years; backwages consequent to illegal dismissal follow that four-year period. Different periods may govern unfair labor practice, overseas employment, social-security benefits, or claims under special legislation.

What can interrupt a civil prescriptive period?

Article 1155 of the Civil Code recognizes three general modes:

Filing the action before the court;
A written extrajudicial demand by the creditor; and
A written acknowledgment of the debt by the debtor.

Preserve proof that the demand or acknowledgment was actually received, including registry receipts, courier tracking, signed receiving copies, authenticated email records, or message metadata.

Do not rely on an oral demand, an unsigned payment, or informal negotiations. Do not assume Article 1155 applies to every special statutory period. Some special laws impose strict periods that a demand letter cannot extend. A demand made after the action has already prescribed also does not ordinarily revive the expired claim by itself.

Criminal cases under the Revised Penal Code

Article 90, as amended by Republic Act No. 4661, generally provides:

Penalty prescribed by law	Prescriptive period
Death, reclusion perpetua, or reclusion temporal	20 years
Other afflictive penalties	15 years
Correctional penalties generally	10 years
Arresto mayor	5 years
Libel or similar offenses	1 year
Oral defamation or slander by deed	6 months
Light offenses	2 months

When the penalty fixed by law is compound, the highest penalty is used for the Article 90 calculation. Use the penalty prescribed by the statute—not an estimate of the sentence a court might eventually impose. The consolidated rule is reflected in Article 90 of the Revised Penal Code and Republic Act No. 4661.

Under Article 91:

The clock generally begins upon discovery by the offended party, authorities, or their agents;
Filing the complaint or information interrupts prescription;
The period may begin running again when the proceedings terminate without conviction or acquittal, or are unjustifiably stopped for a reason not attributable to the accused; and
The period does not run while the offender is absent from the Philippines.

The effect of absence, dismissal, delay, or termination must be established from the record and applicable jurisprudence.

Cyber libel

The Supreme Court has held that cyber libel prescribes in one year from discovery of the allegedly defamatory publication by the offended party, authorities, or their agents. Publication is the starting date only when it coincides with discovery. The Court abandoned the earlier view that cyber libel carried a much longer period. See Causing v. People, G.R. No. 258524, as affirmed by the Supreme Court En Banc in 2026.

This does not mean every later viewing, sharing, or online appearance automatically creates a new publication or restarts the period. That conclusion depends on the charged act and evidence.

Criminal offenses under special laws

First read the special law itself. If it supplies its own prescriptive period, that provision controls. If it does not, Act No. 3326 generally provides:

Maximum imprisonment under the special law	General period
Fine only, or imprisonment not exceeding 1 month, or both	1 year
More than 1 month but less than 2 years	4 years
At least 2 years but less than 6 years	8 years
At least 6 years	12 years
Municipal-ordinance violation	2 months

The amended statutory text is available from the Supreme Court E-Library.

These defaults do not apply where another statute provides a different rule. Examples include:

Tax offenses under the National Internal Revenue Code, generally governed by the Code’s own five-year provision;
Trafficking offenses, for which the special law provides ten- or twenty-year periods depending on the circumstances;
Enforced or involuntary disappearance, which is treated as a continuing offense and generally does not prescribe while the victim remains missing; and
Crimes under Republic Act No. 9851 involving international humanitarian law, genocide, and crimes against humanity, which do not prescribe.

What filing interrupts criminal prescription?

Under Rule 110, a criminal action is instituted, depending on the offense, by filing the complaint with the proper prosecutor or by filing the complaint or information in the proper first-level court. Institution generally interrupts prescription unless a special law provides otherwise.

In its 2025 En Banc decision in People v. Consebido, the Supreme Court clarified prospectively that filing a criminal complaint with the proper prosecution office interrupts prescription even for offenses covered by the Rules on Expedited Procedures in the First Level Courts. The decision also confirmed that preliminary investigation interrupts prescription, while emphasizing that the complaint must be filed before the offense has already prescribed. See G.R. No. 258563, April 2, 2025.

Because older cases applied different rules to municipal ordinances and summary-procedure offenses, the dates of the offense and filing—and the prospective effect of Consebido—must be checked carefully.

A police blotter, report to an employer, social-media report, or administrative grievance is not necessarily the criminal complaint contemplated by the Rules. File with the proper prosecution office or court and retain proof of docketing.

Barangay conciliation and other preliminary proceedings

When a dispute falls within the authority of the lupon, barangay conciliation is ordinarily a condition before filing in court or another adjudicatory office. Under Section 410(c) of the Local Government Code:

Filing the complaint with the punong barangay interrupts the prescriptive period while mediation, conciliation, or arbitration is pending;
The period resumes when the complainant receives the appropriate certificate or complaint after repudiation; and
The statutory interruption cannot exceed 60 days from filing with the punong barangay.

The law also permits direct resort to court in specified situations, including when the action may otherwise become barred by prescription. See Republic Act No. 7160, Sections 410 and 412.

Do not wait automatically for the full barangay process when the deadline is imminent. Obtain immediate advice on whether the dispute is within lupon authority or qualifies for direct filing.

Labor disputes are generally subject to mandatory conciliation-mediation under Republic Act No. 10396. Current labor rules may give a duly filed Request for Assistance a tolling effect, but coverage, exclusions, endorsement, and the correct adjudicatory forum still matter.

Ordinary private negotiations, mediation conducted without statutory authority, complaints to regulators, and internal company investigations do not automatically suspend prescription. Confirm the legal effect of each proceeding rather than assuming that “a complaint has already been filed somewhere.”

How to count the period

As a general computation guide:

Exclude the day of the act or event from which the period begins.
Include the last day.
Treat a “year” as 12 calendar months under Section 31 of the Administrative Code of 1987.
Under Rule 22, if the last day of an applicable court-filing period falls on a Saturday, Sunday, or legal holiday where the court sits, filing on the next working day is generally timely.

For example, if a ten-year civil cause of action unquestionably accrued on June 15, 2021 and no special rule or interruption applies, the ordinary endpoint would be June 15, 2031.

This is only a calendar illustration. The real dispute is often the correct accrual date, legal classification, or tolling effect. Special statutes and tribunal rules may also use working days, calendar days, receipt dates, publication dates, or nonextendible periods. File before the final day whenever possible.

Practical steps to take now

Build a dated chronology. Include the transaction, breach, discovery, every demand, every response, preliminary proceeding, dismissal, reconsideration, and prior filing.
List all possible legal theories. Ask which statute creates each right and which forum has authority to decide it.
Calculate three dates. Compute from the earliest plausible starting date, the most likely date, and any later date you believe is legally supportable. Act on the earliest.
Verify tolling with documents. A claim that the clock stopped should be supported by a docket stamp, receiving copy, proof of receipt, certificate to file action, or official order.
Complete mandatory pre-filing steps promptly. Tell the barangay, conciliator, prosecutor, or lawyer in writing if prescription is near.
Prepare the initiating pleading while preliminary steps continue. Do not wait for the final week to identify parties, obtain addresses, secure records, calculate fees, or determine venue.
Confirm actual filing. Keep the case number, stamped copy, electronic acknowledgment, official receipt, and proof of service.
Continue preserving evidence. Filing on time prevents prescription; it does not prove the merits.

Evidence to preserve

Keep original or reliable copies of:

Contracts, promissory notes, checks, invoices, receipts, and account statements;
Demand letters and complete proof of sending and receipt;
Notices of dishonor, termination, assessment, denial, or final decision;
Barangay complaints, minutes, certificates, and dates of receipt;
Prosecutor, court, labor, and administrative docket records;
Emails, chat exports, text messages, call logs, and attachments;
Online posts with URLs, account details, timestamps, screenshots, and downloaded files;
Photographs, videos, CCTV footage, and unedited original files;
Medical records, police reports, and incident reports;
Payroll, time records, payslips, employment contracts, and company notices;
Land titles, deeds, tax declarations, surveys, and registry records; and
Names, addresses, and current contact details of witnesses.

Do not crop, alter, overwrite, or delete the only copy of digital evidence. Preserve metadata and record how and when each item was obtained.

Common mistakes

Counting from the date a lawyer was consulted instead of the legally relevant event;
Assuming all cases have four- or ten-year periods;
Relying on the Civil Code without checking a special law;
Treating every demand letter as a new starting point;
Assuming an oral demand, partial payment, or settlement discussion stopped the clock;
Believing a police blotter or agency complaint necessarily commenced a criminal case;
Waiting for barangay proceedings beyond their limited tolling effect;
Confusing a one-year ejectment period with all possible actions concerning possession;
Assuming registered land makes every related claim imprescriptible;
Counting from discovery where the law does not recognize a discovery rule;
Ignoring separate deadlines for appeal, reconsideration, protest, or administrative review;
Filing in the wrong forum or through an unauthorized channel;
Omitting a necessary party or the correct offense from the timely filing;
Failing to pay required filing fees or preserve proof of payment; and
Waiting for perfect evidence before protecting the deadline.

When legal help is urgent

Consult a Philippine lawyer immediately if:

Any possible deadline is within 30 days;
The matter involves detention, an arrest warrant, violence, threats, abuse, trafficking, or a missing person;
A dismissal, eviction, foreclosure, tax assessment, government claim, or administrative decision has just been received;
A court or agency order has a period for appeal or reconsideration;
The opposing party is leaving the country, disposing of property, or destroying evidence;
A required demand, barangay proceeding, or administrative remedy remains unfinished near the deadline;
The case was previously dismissed or filed in another forum;
Several laws could apply; or
The claim involves old, concealed, continuing, or repeated conduct.

The Public Attorney’s Office may assist qualified indigent persons. The Integrated Bar of the Philippines and accredited legal-aid organizations may also provide referral or assistance, subject to eligibility and availability.

Frequently asked questions

Does sending a demand letter always extend the deadline?

No. Article 1155 recognizes a written extrajudicial demand as an interruption for applicable civil actions, but special statutory periods may not be interruptible that way. The demand must also concern the right being enforced, and receipt should be provable.

Does filing at the barangay stop prescription?

Only within the scope and limits of the Local Government Code. The interruption generally begins upon filing with the punong barangay and cannot exceed 60 days. Some urgent or nearly prescribed cases may go directly to court.

Does a police report stop criminal prescription?

Not necessarily. A police report or blotter is not automatically the complaint or information that legally institutes the criminal action. Secure proof of filing with the proper prosecution office or court.

Can the deadline run before I discover the wrongdoing?

Yes, unless the governing law or controlling jurisprudence applies a discovery rule. Discovery is expressly relevant to many criminal offenses, but it is not a universal rule for civil claims.

What if several causes of action arise from the same incident?

Calculate each separately. A contractual claim, quasi-delict, civil liability arising from a crime, administrative complaint, and criminal prosecution can have different periods and filing rules.

Do negotiations suspend prescription?

Usually not by themselves. A written demand, written acknowledgment, statutory mediation, or formal filing may have an effect, but ongoing discussions alone are unsafe grounds for delaying suit.

What if the last day falls on a weekend or holiday?

Rule 22 generally moves an applicable court-filing deadline to the next working day when the last day falls on a Saturday, Sunday, or legal holiday where the court sits. Confirm that the particular statute or tribunal follows that rule and avoid relying on the extension unnecessarily.

Can a prescribed claim be revived by a new demand?

Ordinarily, a demand made after prescription has completed does not revive the expired action by itself. A new written undertaking, acknowledgment, novation, or promise may create different issues, but its validity and effect depend on the document and circumstances.
