Quick answer

There is no single prescriptive period for filing a legal case in the Philippines. The correct deadline depends on at least four things: the exact cause of action or offense, the law that creates it, the date the right to sue or prosecute arose, and any event that interrupted or suspended the running of the period.

For civil cases, the starting point is often Articles 1139 to 1155 of the Civil Code. Common periods include 10 years for actions upon a written contract, six years for an oral contract, four years for injury to rights or quasi-delict, and one year for defamation and forcible entry or unlawful detainer, subject to special rules on when the cause of action actually accrued. Special statutes can provide a different period and override the general Civil Code rules. (Lawphil)

For crimes under the Revised Penal Code, Article 90 generally determines prescription according to the penalty, while Article 91 determines when the period begins and what interrupts it. Crimes under special penal laws may instead be governed by the special statute itself or, if it contains no prescription rule, by Act No. 3326. (Lawphil)

The safest method is therefore not to start by asking, “How many years do I have?” Start by identifying exactly what legal claim or offense exists, then identify the controlling statute, determine the legally correct starting date, check for interruption or suspension, and calculate the deadline.

The five questions that determine prescription

A proper prescription analysis usually follows this sequence:

What exactly is the claim, cause of action, or criminal offense?
Does a special law prescribe its own filing period?
If not, what general prescription rule applies?
On what date did the prescriptive period legally begin to run?
Was the period interrupted, suspended, extended, or restarted before it expired?

A mistake at any one of these stages can change the result completely.

For example, two cases arising from the same event may have different deadlines. An employee dismissed from work may generally have four years to contest an illegal dismissal, while particular unpaid wages or benefits may be recoverable only within the three-year period for labor money claims. (Lawphil)

Likewise, the civil action for defamation generally prescribes in one year, and the Supreme Court has now confirmed that criminal cyber libel likewise prescribes in one year, although the criminal period is reckoned according to the rules governing discovery of the offense. (Lawphil)

Step 1: Identify the exact legal basis of the case

Prescription attaches to a particular legal right or offense, not merely to the factual event.

Suppose money was not paid. The case might arise from:

a written loan agreement;
an oral agreement;
unjust enrichment or another quasi-contract;
a judgment that has already become final;
an employer-employee relationship;
a negotiable instrument;
a sale governed by a special statute; or
another statutory obligation.

Those classifications can produce different prescriptive periods.

Similarly, conduct that appears to be “fraud” in ordinary language could potentially involve estafa, falsification, a civil action for damages, annulment of a contract, rescission, a securities violation, a tax offense, or another special-law offense. The label used by the complainant does not determine the period; the actual elements and legal basis do.

This is why a prescription analysis should begin with the statute and the facts necessary to establish the cause of action.

Step 2: Check whether a special law controls

The Civil Code itself recognizes that its general limitation periods are subject to periods established elsewhere in the Code and in special laws. (Lawphil)

Accordingly, never assume that the familiar Civil Code periods automatically apply.

Examples include labor law, tax law, family law, election law, administrative law, intellectual-property statutes, special penal laws, and specialized remedies under the Rules of Court.

A special statute may provide:

a shorter or longer period;
a different starting date;
a discovery rule;
its own interruption rule;
an administrative filing requirement before court action;
a non-extendible protest or appeal period; or
no prescriptive period at all.

For example, Article 39 of the Family Code, as amended by Republic Act No. 8533, provides that an action or defense for declaration of absolute nullity of marriage does not prescribe. By contrast, annulment of a voidable marriage under Article 47 is subject to specific periods depending on the ground—for example, an action based on fraud must generally be filed by the injured party within five years after discovery of the fraud. (Lawphil)

The lesson is simple: look for the special rule before applying a general one.

Common Civil Code prescriptive periods

Subject to special statutes and rules on accrual, the Civil Code provides the following important periods:

Type of civil action	General period
Recovery of movables	8 years
Real action over immovable property	30 years
Mortgage action	10 years
Action upon a written contract	10 years
Action upon an obligation created by law	10 years
Action upon a judgment	10 years
Action upon an oral contract	6 years
Action upon a quasi-contract	6 years
Action for injury to the plaintiff's rights	4 years
Action based on quasi-delict	4 years
Forcible entry or unlawful detainer	1 year
Civil action for defamation	1 year
Other actions whose periods are not fixed elsewhere	5 years

These periods come principally from Articles 1140 to 1149 of the Civil Code. (Lawphil)

The table is only a starting point. The decisive issue is frequently when the right of action accrued.

Written contracts: generally 10 years

Article 1144 gives a 10-year period for an action based upon a written contract. But the period does not necessarily begin on the date the agreement was signed.

Under Article 1150, absent a special rule, prescription runs from the day the action may legally be brought. The Supreme Court has explained that the relevant point is ordinarily the breach or other event that gives the claimant the legal right to sue. (Lawphil)

Thus, if a written loan becomes payable on a later maturity date, the analysis ordinarily focuses on when payment became enforceable or the obligation was breached—not simply when the loan document was executed.

Oral contracts: generally six years

Article 1145 provides a six-year period for an action upon an oral contract. (Lawphil)

The existence and terms of the oral agreement may themselves become evidentiary issues, so messages, receipts, bank transfers, admissions, recordings lawfully obtained, and witnesses can become important.

Injury to rights and quasi-delict: generally four years

Article 1146 generally provides four years for an action based upon an injury to the plaintiff's rights or a quasi-delict. (Lawphil)

This provision is also the basis for the Supreme Court's long-standing rule that a complaint for illegal dismissal generally prescribes in four years, because wrongful dismissal is treated as an injury to the employee's rights. (Lawphil)

Defamation: generally one year

A civil action for defamation generally falls under the one-year period in Article 1147. (Lawphil)

Do not automatically assume that the same starting date applies to the corresponding criminal case. Civil and criminal prescription are governed by different provisions.

Judgments: distinguish prescription from execution by motion

Article 1144 includes an action upon a judgment within the 10-year period, and Article 1152 reckons the period from the time the judgment becomes final. But Rule 39 creates an important procedural distinction.

A final and executory judgment may generally be executed by motion within five years from entry. After that period, and before the judgment becomes barred by prescription, enforcement generally requires an independent action to revive or enforce the judgment. (Lawphil)

Someone holding an old judgment should therefore not simply assume that “there are 10 years” and postpone action.

Step 3: Determine when the cause of action accrued

Knowing the length of the period is only half the analysis. You must also identify the reckoning date.

Article 1150 provides the general Civil Code rule: unless a special provision says otherwise, prescription is counted from the day the action may be brought. (Lawphil)

The Supreme Court has described a cause of action as involving:

a legal right in favor of the claimant;
a corresponding obligation on the defendant; and
an act or omission violating that right or obligation. (Lawphil)

The clock therefore ordinarily starts when the last necessary element exists so that the claimant can legally maintain the action.

The date of the transaction is not always the starting date

A contract may be signed today but become due years later.

An employer may accrue a particular monetary obligation on every pay period.

A fraudulent act may be subject to a statutory discovery rule.

A judgment has its own reckoning rule.

A continuing contractual relationship can involve several obligations accruing on different dates.

Do not choose the earliest date appearing in the documents without first asking what event actually made the claim enforceable.

Step 4: Check whether prescription was interrupted

For many civil actions governed by the Civil Code, Article 1155 is extremely important.

Prescription is interrupted when:

an action is filed before the court;
the creditor makes a written extrajudicial demand; or
the debtor makes a written acknowledgment of the debt. (Lawphil)

The Supreme Court has repeatedly explained that interruption under Article 1155 is more than simply pausing the clock. A qualifying written extrajudicial demand ordinarily wipes out the period already elapsed and causes the applicable prescriptive period to begin anew from receipt of the demand. (Lawphil)

Example

Assume a written contractual claim is subject to a 10-year period and the cause of action accrued on June 1, 2020.

If a legally sufficient written demand interrupting prescription is received on June 1, 2025, Article 1155 jurisprudence may cause a new 10-year period to run from the receipt of that demand.

But do not generalize this rule to every legal deadline. A special statute may have its own exclusive rules for interruption, and some procedural deadlines cannot be restarted simply by sending a demand letter.

Preserve proof of receipt

If relying on a written demand to interrupt prescription, preserve:

the signed demand;
proof of delivery;
registry receipts and return cards;
courier tracking;
authenticated email records, if applicable;
acknowledgments of receipt;
replies from the recipient; and
any written acknowledgment of the obligation.

The date a letter was prepared is not necessarily the legally significant date. Receipt can matter.

Barangay conciliation can affect prescription

For disputes within the authority of the Katarungang Pambarangay system, barangay conciliation may be a statutory precondition before filing in court.

Section 410(c) of the Local Government Code provides that, while a dispute is under mediation, conciliation, or arbitration, the applicable prescriptive periods for offenses and causes of action are interrupted upon filing the complaint with the punong barangay.

The period resumes upon receipt of the appropriate certificate allowing further action, but the statutory interruption cannot exceed 60 days from the filing of the barangay complaint. (Lawphil)

This rule is especially important for claims already close to their deadline. Filing at the barangay does not provide unlimited additional time.

Barangay conciliation also does not apply to every dispute. Section 412 and Supreme Court guidance recognize statutory exceptions and limitations. (Lawphil)

Prescription in criminal cases under the Revised Penal Code

For offenses punished under the Revised Penal Code, Article 90 generally provides:

Classification under Article 90	Prescriptive period
Crimes punishable by death, reclusion perpetua, or reclusion temporal	20 years
Crimes punishable by other afflictive penalties	15 years
Crimes punishable by correctional penalties, generally	10 years
Crimes punishable by arresto mayor	5 years
Libel or similar offenses	1 year
Oral defamation and slander by deed	6 months
Light offenses	2 months

If the penalty prescribed by law is compound, Article 90 directs that the highest penalty be used for purposes of the applicable general classification. (Lawphil)

The penalty must be examined under the statute actually in force and applicable to the offense. Do not calculate prescription simply from the penalty that a complainant expects the accused ultimately to receive after mitigating or aggravating circumstances.

When does criminal prescription begin?

Article 91 of the Revised Penal Code provides that prescription generally begins from the day the crime is discovered by the offended party, the authorities, or their agents.

It is interrupted by the filing of the complaint or information and may begin to run again if the proceedings terminate without conviction or acquittal or are unjustifiably stopped for a reason not attributable to the accused. Article 91 also provides that the period does not run while the offender is absent from the Philippines. (Lawphil)

The discovery date can therefore be a factual issue requiring evidence.

Cyber libel: the Supreme Court has confirmed a one-year period

A particularly important recent development concerns cyber libel.

In Causing v. People, G.R. No. 258524, with the Court's April 2026 resolution denying the motions for partial reconsideration with finality, the Supreme Court confirmed that cyber libel under the Cybercrime Prevention Act prescribes in one year under Article 90's specific rule for libel. (Lawphil)

The Court also held that the one-year period is reckoned from discovery of the alleged defamatory material by the offended party, the authorities, or their agents, rather than automatically presuming discovery on the date a social-media post was uploaded. Whether and when actual discovery occurred may require evidence. (Lawphil)

This illustrates why merely knowing the number “one year” is insufficient. The starting date may decide the case.

Criminal offenses under special laws

When a special penal statute expressly states its own prescriptive period, that provision controls.

If the special statute does not provide a period, Act No. 3326 generally supplies the following framework:

Penalty under the special law	General period under Act No. 3326
Fine only, or imprisonment not exceeding 1 month, or both	1 year
Imprisonment exceeding 1 month but less than 2 years	4 years
Imprisonment of 2 years or more but less than 6 years	8 years
Imprisonment of 6 years or more	12 years
Municipal-ordinance violation	2 months

Act No. 3326 applies only when the special law does not itself provide a different rule. (Lawphil)

For special-law offenses, the exact rules concerning commission, discovery, investigation, and interruption must be read together with the particular statute and current Supreme Court jurisprudence.

A major 2025 Supreme Court ruling on criminal interruption

Older cases produced complications over whether filing a complaint with the prosecutor, rather than filing the information in court, interrupted prescription for offenses subject to summary procedure.

The Supreme Court addressed that problem en banc in People v. Consebido, G.R. No. 258563, April 2, 2025. The Court prospectively ruled that filing the criminal complaint before the prosecution office tolls the running of the prescriptive period, including offenses that may be covered by the 2022 Rules on Expedited Procedures in the First Level Courts. It expressly abandoned contrary rulings on that issue for purposes of the new rule. (Lawphil)

Because the Court made the rule prospective, older criminal cases can require careful examination of the date of the offense, the filing history, and the jurisprudence then applicable.

Current prosecution practice is also governed by the DOJ's 2024 rules on preliminary investigations and inquest proceedings and its rules on summary investigation and expedited preliminary investigation for offenses carrying lower penalties. (Department of Justice)

Labor cases have their own periods

Labor disputes provide a good example of why the nature of the claim matters.

Illegal dismissal: generally four years

The Supreme Court treats illegal dismissal as an injury to the employee's rights under Article 1146 of the Civil Code. The complaint must generally be filed within four years from accrual of the cause of action. (Lawphil)

Money claims: generally three years

Article 306 of the renumbered Labor Code provides that money claims arising from employer-employee relations must generally be filed within three years from accrual, otherwise they are barred. (Department of Labor and Employment)

This can apply to claims such as unpaid wages, differentials, or particular statutory benefits, subject to rules governing when each benefit becomes demandable.

For recurring obligations, some installments may already have prescribed while later ones remain recoverable. In a 2025 decision involving 13th-month pay, the Supreme Court limited recovery according to the three-year period under Article 306. (Lawphil)

Certain benefits also have special accrual rules. The Supreme Court has, for example, treated service incentive leave differently because its monetary equivalent may accrue upon the employer's refusal to pay after demand or upon termination, depending on the circumstances. (Lawphil)

Tax prescription is a separate legal system

Tax cases should not be analyzed using ordinary Civil Code periods.

Under Section 203 of the National Internal Revenue Code, the BIR generally has three years to assess internal revenue taxes, counted from the statutory filing deadline or the actual filing of a late return, as applicable. (Lawphil)

Section 222 provides important exceptions. In the case of a false or fraudulent return with intent to evade tax, or failure to file the required return, an assessment or qualifying collection proceeding may generally be undertaken within 10 years after discovery of the falsity, fraud, or omission. (Lawphil)

Criminal violations of the NIRC have a different rule. Section 281 provides a five-year criminal prescriptive period, with its own rules on commencement and interruption. The Supreme Court discussed those provisions extensively in People v. Consebido. (Lawphil)

Taxpayers and government agencies therefore must distinguish:

prescription of an assessment;
prescription of tax collection;
protest and appeal deadlines; and
prescription of a criminal tax offense.

They are not interchangeable.

Do not confuse prescription with appeal or procedural deadlines

A prescriptive period determines how long a substantive claim or offense may generally be pursued.

A reglementary or procedural period may govern a different step, such as:

answering a complaint;
filing a motion for reconsideration;
appealing a judgment;
protesting an administrative determination;
seeking judicial review; or
complying with a mandatory administrative remedy.

These periods can be dramatically shorter.

For example, appeals from many final court judgments are generally subject to a 15-day period, although the applicable rule, type of case, tribunal, and post-judgment motion must always be checked. (Lawphil)

A person may therefore have filed the original case well within prescription but still lose the right to appeal by missing a later procedural deadline.

How to count the final day

Once the correct starting event and length of time have been established, count carefully.

Rule 22 of the Rules of Court provides that, when computing a period prescribed by the Rules, a court order, or an applicable statute:

the day of the event from which the period begins is excluded;
the final day is included; and
if the last day falls on a Saturday, Sunday, or legal holiday in the place where the court sits, the period ordinarily extends to the next working day. (Lawphil)

For statutory periods expressed in years, Section 31 of the Administrative Code of 1987 defines a “year” as 12 calendar months. The Supreme Court has applied that definition in computing legal periods. (Lawphil)

Still, a special statute or procedural rule can provide a different method, so the controlling provision must always be checked.

A practical prescription worksheet

Before concluding that a case is timely or prescribed, write down the following:

1. Exact legal claim or offense: Do not use a broad description such as “fraud,” “harassment,” or “unpaid debt.” Identify the statute and legal theory.

2. Applicable provision on prescription: Record the exact article, section, rule, or special law.

3. Length of period: For example: one year, three years, four years, 10 years.

4. Accrual or discovery event: State exactly what happened that legally started the clock.

5. Starting date: Use a specific calendar date.

6. Interrupting or suspending events: Examples may include a written demand, acknowledgment of debt, court filing, prosecutor filing, or barangay proceeding, depending on the governing law.

7. Evidence supporting each date: Identify documents, receipts, emails, affidavits, official records, court stamps, prosecutor stamps, or certificates.

8. Adjusted deadline: Recalculate only after determining the legal effect of each interruption.

9. Correct forum and pre-filing requirement: Check whether the case belongs before a court, prosecutor, labor tribunal, administrative agency, barangay, tax tribunal, or another forum.

Evidence to preserve when prescription may become disputed

Prescription frequently turns on dates. Preserve evidence showing:

the date a contract was signed;
the due date or maturity date;
invoices and billing statements;
dates of partial payments;
written acknowledgments of debt;
demand letters and proof of receipt;
emails and authenticated electronic communications;
termination letters and payroll records;
incident reports;
medical records where relevant;
screenshots together with information showing when online material was actually discovered;
original URLs, metadata, and archived copies of online material;
police or barangay records;
complaint-affidavits;
prosecutor receiving stamps;
court filing receipts;
barangay certificates to file action;
administrative decisions and proof of receipt;
tax returns and electronic filing confirmations; and
judgments, entries of judgment, and notices of receipt.

Do not alter electronic evidence or rely only on cropped screenshots if the original data can be preserved.

Common mistakes when calculating prescription

Counting from the wrong event

The transaction date, discovery date, maturity date, breach date, last demand, dismissal date, registration date, and date of filing can all be different. The law determines which one matters.

Applying the Civil Code when a special statute controls

Special laws frequently contain their own limitation periods.

Assuming every written demand restarts every deadline

Article 1155 is powerful in qualifying civil cases, but it does not override a special law that supplies its own prescription regime.

Treating criminal and civil prescription as identical

A single act can produce both criminal and civil liability, but the periods and reckoning rules may differ.

Waiting for negotiations to finish

Settlement discussions do not automatically suspend prescription. Unless the governing law recognizes an interrupting event, the clock may continue while the parties negotiate.

Assuming a barangay complaint gives unlimited extra time

The Local Government Code limits the statutory interruption arising from barangay conciliation to 60 days. (Lawphil)

Ignoring proof of receipt

A deadline may run from notice or receipt rather than issuance. Keep envelopes, electronic acknowledgments, registry cards, and receiving copies.

Treating all recurring claims as one claim

Periodic salaries, rentals, installments, benefits, or similar obligations can accrue separately. Older installments may prescribe even while newer ones remain actionable.

Waiting until the calculated last day

A complaint can still encounter problems involving jurisdiction, venue, barangay conciliation, filing fees, verification, supporting affidavits, electronic filing requirements, or the correct prosecutorial office. Filing well before the deadline is safer.

When legal help is urgent

Seek prompt legal assistance when:

the possible deadline is within the next few weeks or months;
the date of accrual or discovery is disputed;
there have been several written demands or acknowledgments;
a case was previously dismissed and may need to be refiled;
the dispute passed through barangay proceedings;
the matter involves cyber libel or another short-prescription offense;
the accused was outside the Philippines for part of the period;
a prosecutor's office received a criminal complaint near the deadline;
the claim involves recurring labor benefits;
an old judgment has not been executed;
an administrative decision has already been received;
a tax assessment, protest, or collection deadline is involved; or
more than one statute could plausibly govern the same facts.

Where prescription is close, determining the correct legal theory before filing can be as important as calculating the number of days remaining.

Frequently asked questions

Does sending a demand letter stop prescription?

For civil actions governed by Article 1155 of the Civil Code, a written extrajudicial demand by the creditor can interrupt prescription. Supreme Court jurisprudence states that a qualifying interruption causes the period to begin anew from receipt of the demand. (Lawphil)

But special statutes may use different rules. A demand letter should not be assumed to extend every statutory deadline.

Does an oral demand interrupt a Civil Code prescriptive period?

Article 1155 specifically refers to a written extrajudicial demand and a written acknowledgment of debt. An oral conversation should therefore not be relied upon as the statutory interruption contemplated by that provision. (Lawphil)

If negotiations are ongoing, does prescription stop?

Not automatically. Settlement discussions alone are not one of Article 1155's listed grounds for interruption. Examine whether the negotiations produced a written acknowledgment, written demand, agreement, or another legally recognized event.

If I filed in the wrong court, is prescription automatically saved?

Do not assume so. Philippine jurisprudence recognizes circumstances in which a judicial filing can interrupt prescription even when the first action is later dismissed, but the effect depends on the governing law and procedural history. A 2025 Supreme Court decision reiterated Article 1155's interruption rule in a case involving an earlier action dismissed on procedural grounds. (Lawphil)

Because jurisdiction, good faith, the type of claim, and special statutory rules may matter, a defective filing should never be used deliberately as a prescription strategy.

When does a debt prescribe?

It depends on the legal basis. A written contract generally falls under the 10-year rule; an oral contract generally falls under the six-year rule. The clock ordinarily begins when the creditor has a legal right to enforce payment, subject to maturity, acceleration provisions, written demands, acknowledgments, partial performance, and any special statute. (Lawphil)

How long do I have to file an illegal-dismissal case?

Generally four years from accrual of the cause of action. Separate monetary claims arising from the employment relationship are generally subject to the Labor Code's three-year period. (NLRC)

How long do I have to file cyber libel?

The Supreme Court has confirmed that criminal cyber libel generally prescribes in one year from discovery by the offended party, the authorities, or their agents, subject to the rules on interruption and the particular evidence concerning discovery. (Lawphil)

Does filing a criminal complaint with the prosecutor interrupt prescription?

Under the Supreme Court's prospective ruling in People v. Consebido in 2025, filing the criminal complaint before the prosecution office tolls prescription, including for offenses covered by the 2022 expedited procedures. Older cases may require analysis of the rules and jurisprudence applicable when the relevant filings occurred. (Lawphil)

Can some legal actions be filed at any time?

Yes. Some rights are expressly imprescriptible. For example, Article 39 of the Family Code provides that an action or defense for declaration of absolute nullity of marriage does not prescribe. The Civil Code also identifies certain rights, including the right to demand a right of way and to seek abatement of a public or private nuisance, as not extinguished by prescription. (Lawphil)

That does not mean every remedy connected with those matters is automatically free from all procedural deadlines.
