The Philippine judicial system vests judicial power in one Supreme Court and in such lower courts as may be established by law under Article VIII of the 1987 Constitution. The principal statutes governing court structure and jurisdiction are Batas Pambansa Blg. 129 (Judiciary Reorganization Act of 1980), as amended by Republic Act No. 7691 and Republic Act No. 11576, together with the Rules of Court (1997, as amended) and special procedural rules. Filing a case requires strict compliance with rules on jurisdiction, venue, parties, cause of action, pleadings, and pre-filing conditions. Non-compliance commonly results in dismissal.

The Court Hierarchy and Subject-Matter Jurisdiction

Courts are organized in tiers. The Supreme Court exercises appellate and certain original jurisdiction. The Court of Appeals, Sandiganbayan, and Court of Tax Appeals occupy the second level. Regional Trial Courts (RTC) serve as the primary trial courts of general jurisdiction. First-level courts comprise Metropolitan Trial Courts (MeTC) in Metro Manila, Municipal Trial Courts in Cities (MTCC), Municipal Trial Courts (MTC), and Municipal Circuit Trial Courts (MCTC).

Civil jurisdiction (primarily Rule 2 and Section 19 of Batas Pambansa Blg. 129, as amended):

First-level courts exercise exclusive original jurisdiction over civil actions where the amount of the demand or claim (exclusive of interest, damages of whatever kind, attorney’s fees, litigation expenses, and costs) does not exceed Two Million Pesos (₱2,000,000.00). For real actions involving title to or possession of real property, jurisdiction depends on the assessed value of the property: first-level courts handle cases where the assessed value does not exceed ₱2,000,000.00 outside Metro Manila and ₱5,000,000.00 within Metro Manila.
RTC exercises exclusive original jurisdiction over all other civil actions, including those incapable of pecuniary estimation, real actions exceeding the above assessed-value thresholds, and cases involving admiralty, maritime, and intellectual property matters not otherwise assigned.
Family Courts (designated RTC branches under Republic Act No. 8369) have exclusive jurisdiction over annulment of marriage, legal separation, adoption, guardianship, custody, support, and other family-related matters.
Special Commercial Courts (designated RTC branches) handle intra-corporate controversies, rehabilitation, and liquidation cases.

Criminal jurisdiction (Section 32 of Batas Pambansa Blg. 129):

First-level courts have exclusive original jurisdiction over all offenses punishable by imprisonment not exceeding six (6) years, irrespective of the amount of fine and regardless of accessory penalties.
RTC exercises jurisdiction over offenses punishable by imprisonment exceeding six (6) years, and over certain special laws cases.
Sandiganbayan has jurisdiction over graft and corrupt practices cases involving public officers with Salary Grade 27 and above, or involving higher amounts.

Special proceedings (Rules 72–109) such as settlement of estate, guardianship, adoption, and habeas corpus are generally filed in the RTC, with limited exceptions for MTC in small estates or habeas corpus applications.

Venue

Venue determines the geographic location of filing and is governed by Rule 4 of the Rules of Court for civil actions and Rule 110 for criminal actions. Venue is procedural and may be waived by failure to object timely.

Real actions (title to or possession of real property): filed in the court where the property or any part thereof is situated.
Personal actions (recovery of personal property, sum of money, or damages): filed in the court where the plaintiff or defendant resides, at the plaintiff’s election. If both parties are non-residents, venue lies where the plaintiff resides or where the defendant may be found.
Criminal actions: generally filed in the court of the municipality or city where the offense was committed or where any of its essential ingredients occurred. For offenses committed on a vessel or in transit, specific rules apply under Rule 110, Section 15.

Parties, Capacity, and Real Party in Interest

Every action must be prosecuted and defended in the name of the real party in interest (Rule 3, Section 2). A real party in interest is the party who stands to be benefited or injured by the judgment. Juridical persons (corporations, partnerships) sue and are sued through authorized representatives. Minors, incompetents, and estates act through guardians or administrators. Indispensable parties must be joined; failure to implead them may result in dismissal. Permissive joinder of parties is allowed when there is a common question of law or fact and the claims arise from the same transaction (Rule 3, Section 6). Misjoinder or non-joinder is not ground for dismissal; the court may order joinder or drop parties at any stage.

Cause of Action

A cause of action exists when there is (1) a legal right in favor of the plaintiff, (2) a correlative obligation of the defendant, (3) an act or omission by the defendant violating that right, and (4) resulting damage or injury to the plaintiff (Rule 2, Section 2). A complaint that fails to state a cause of action is dismissible under Rule 16. Multiple causes of action may be joined in one complaint provided they arise from the same transaction or series of transactions and do not require separate trials (Rule 2, Section 5). Splitting a single cause of action is prohibited and may bar subsequent actions.

Pleadings and Initiatory Requirements

Pleadings are the written allegations of the parties (Rule 6). The initiatory pleading is the complaint (ordinary civil action) or petition (special civil action or special proceeding).

Mandatory contents of a complaint (Rule 7, Section 1):

Designation of the court;
Names and addresses (residence or business) of the parties;
Body containing the ultimate facts constituting the cause or causes of action and the relief prayed for;
Date of the pleading.

The pleading must be signed by the party or counsel (Rule 7, Section 3). A verification is required for all complaints and most initiatory pleadings. It must be based on personal knowledge or authentic records and state that the allegations are true and correct (Rule 7, Section 4). A Certificate of Non-Forum Shopping (CNFS) is mandatory in every initiatory pleading. It is a sworn statement that the party has not commenced any other action or proceeding involving the same issues in any court, tribunal, or agency; that to the best of knowledge no such action is pending; and that if any is subsequently filed, the party will report it within five days (Rule 7, Section 5). Failure to attach a proper verification or CNFS is ground for dismissal, although the court may allow amendment in the interest of justice.

When the cause of action is based on a written instrument or document, the original or a copy must be attached to the complaint; otherwise, the reason for non-attachment must be stated (Rule 8, Section 7). Supporting affidavits or documents are not required at filing except in specific proceedings (e.g., small claims, summary procedure, or petitions with provisional remedies).

Small Claims Cases (Revised Rules on Small Claims, A.M. No. 08-8-7-SC, as amended): For money claims not exceeding ₱1,000,000.00 (current threshold), a simplified Statement of Claim on a prescribed form is used. No lawyers are permitted to appear for parties (except when the party is a juridical entity). Filing is directly with the first-level court.

Pre-Filing Conditions

Katarungang Pambarangay (Republic Act No. 7160, Sections 399–422; originally Presidential Decree No. 1508): Mandatory conciliation is required before filing any civil action or criminal complaint for offenses punishable by imprisonment not exceeding one year or fine not exceeding ₱5,000.00, when all parties reside in the same city or municipality. The Lupon Tagapamayapa conducts mediation; if unsuccessful, a Certificate to File Action is issued. Exemptions include cases involving government, provisional remedies, habeas corpus, and certain family or criminal matters. Filing without the certificate renders the action premature and dismissible.

Exhaustion of administrative remedies: Required where a law provides an administrative forum (e.g., labor cases to NLRC, tax cases to BIR or CTA, certain government claims). Failure bars judicial recourse.

Prescription and laches: Actions must be filed within periods prescribed by the Civil Code (e.g., 10 years for written contracts, 4 years for quasi-delicts, 1 year for forcible entry) or special laws. Laches may bar stale claims even within prescriptive periods.

Demand: Not always required, but a prior demand is necessary in certain actions (e.g., rescission, specific performance) and advisable in collection cases to start the running of interest or to prove default.

Procedure for Filing a Civil Action

Preparation: Draft the complaint or petition, verification, and CNFS. Prepare the required number of copies (original for the court, one copy each for all defendants, plus extra copies). Attach copies of actionable documents where applicable.
Payment of docket and other fees (Rule 141, as amended): Fees are based on the amount claimed for money actions or are fixed for other actions. Indigent litigants may file a motion to litigate as pauper with supporting documents (latest income tax return, affidavit of indigency, etc.). If granted, the party is exempt from payment of docket, sheriff’s, and other lawful fees.
Actual filing: Present the pleadings and proof of payment (or pauper order) to the Office of the Clerk of Court of the proper court. The clerk dockets the case, assigns a docket number, and raffles it to a branch if multiple branches exist. The date of filing is the date of payment of fees or granting of pauper status.
Issuance and service of summons (Rule 14): Upon filing, the court issues summons directing the defendant to answer within 15 days (or 30 days if served outside the Philippines). Summons and a copy of the complaint are served by the sheriff or other authorized person. Substituted service, service by publication, or extraterritorial service follows specific rules when personal service fails.
Subsequent steps (for completeness): Defendant files an answer (Rule 11). The court sets pre-trial (Rule 18). Trial follows if issues remain. Provisional remedies (preliminary attachment, injunction, receivership, replevin, support pendente lite) may be applied for simultaneously with or after filing (Rules 57–61).

Procedure for Filing a Criminal Action

Criminal actions are generally commenced by the State through the public prosecutor, although private offended parties play a significant role.

Cases requiring preliminary investigation (penalty of at least four years, two months, and one day of imprisonment):

The offended party executes a Complaint-Affidavit with supporting evidence and files it with the Office of the City or Provincial Prosecutor (or Ombudsman for certain cases).
The prosecutor issues a subpoena to the respondent, who files a Counter-Affidavit within the prescribed period.
A clarificatory hearing may be conducted.
The prosecutor issues a Resolution: dismiss the complaint or find probable cause and file an Information in the proper court.
The court, upon filing of the Information, may issue a warrant of arrest or a summons, depending on the penalty and circumstances. Bail may be applied for.

Cases not requiring preliminary investigation (lower penalties):

The complaint may be filed directly with the first-level court. The court conducts a preliminary examination or proceeds to issue summons or warrant.

Private crimes (adultery, concubinage, seduction, abduction, acts of lasciviousness): The complaint must be filed by the offended party, or in specified cases by the spouse, parents, or grandparents.

Inquest proceedings: When a person is lawfully arrested without a warrant, the inquest prosecutor conducts an inquest within the prescribed periods (12/18/36 hours depending on distance) to determine whether the person should remain in custody or be released.

Filing of Information: Once filed in court, the case is docketed and raffled. Arraignment follows (Rule 116), then pre-trial and trial (Rule 119).

Special Civil Actions and Special Proceedings

Special civil actions (Rules 62–71) such as declaratory relief, interpleader, certiorari, prohibition, mandamus, quo warranto, expropriation, foreclosure of mortgage, and partition have specific initiatory requirements, often including verification and, in some instances, a CNFS. Petitions under Rule 65 (certiorari, prohibition, mandamus) must be verified, filed within 60 days from notice of the assailed act, and accompanied by certified true copies of relevant documents.

Special proceedings (Rules 72–109) are commenced by verified petition. Examples include:

Settlement of estate of deceased persons;
Guardianship of minors or incompetents;
Adoption (governed also by Republic Act No. 8552 and the Rule on Adoption);
Habeas corpus (Rule 102), which may be filed in any court and may be made returnable before any judge.

Supporting documents (death certificates, birth certificates, medical reports, etc.) are attached as required by the specific rule.

Additional Considerations

Electronic filing and e-Court: Many courts, particularly in urban areas, utilize the e-Court system or electronic filing platforms introduced by the Supreme Court. Requirements for electronic signatures, scanned documents, and online payment apply where implemented. Traditional paper filing remains available.

Amendment of pleadings (Rule 10): A complaint may be amended once as a matter of right before a responsive pleading is served, or with leave of court thereafter. Amendments that introduce new causes of action or change the theory of the case are allowed if not prejudicial.

Consolidation and transfer: Related cases pending in different branches or courts may be consolidated for joint trial to avoid multiplicity of suits.

Dismissal for technical defects: Courts are liberal in allowing amendments to cure defects in form, but substantive defects (lack of jurisdiction, no cause of action, prescription, lack of real party in interest) may result in outright dismissal.

Costs and attorney’s fees: Docket fees are assessed at filing. Attorney’s fees may be recovered as damages when stipulated or when the defendant acted in gross and evident bad faith (Civil Code, Article 2208).

This article sets forth the fundamental rules and procedures derived from the Constitution, statutes, and the Rules of Court. Specific cases may involve additional requirements under special laws (e.g., environmental cases under the Rules of Procedure for Environmental Cases, A.M. No. 09-6-8-SC; election contests; agrarian disputes). Practitioners must always verify the latest amendments and Supreme Court circulars applicable to the particular action and court.
