Service of summons is how a court acquires jurisdiction over the person of the defendant (in an action in personam), and it notifies them of the case so they can respond. The preferred mode is personal service — handing the summons to the defendant in person. If, for justifiable reasons, personal service cannot be made within a reasonable time, substituted service is allowed, such as by leaving copies at the defendant's residence with a person of suitable age and discretion residing there, or at their office with a competent person in charge, following the requirements strictly. For a domestic corporation, summons is served on specific officers (such as the president, managing partner, general manager, corporate secretary, treasurer, or in-house counsel). For a defendant who is a non-resident and not found in the country, extraterritorial service is allowed only in certain actions (such as those affecting the personal status of the plaintiff or property in the country), by court leave, through personal service abroad, publication, or other means the court directs. Defective service means the court does not acquire jurisdiction over the defendant, and any judgment against them may be void, although voluntary appearance can cure the defect.
A court cannot bind a defendant it has no jurisdiction over. In most cases, that jurisdiction is acquired through valid service of summons — and defective service can void a judgment.
Why Summons Matters
Service of summons serves two functions in an action in personam (against a person):
- It vests the court with jurisdiction over the person of the defendant; and
- It notifies the defendant of the action so they may respond.
Without valid service (or voluntary appearance), the court cannot render a valid personal judgment.
Personal Service (Preferred)
The preferred mode is personal service — handing the summons to the defendant in person. This is the most reliable form of notice.
Substituted Service
If, for justifiable reasons, personal service cannot be made within a reasonable time, substituted service is allowed, such as by:
- Leaving copies at the defendant's residence with a person of suitable age and discretion residing there; or
- Leaving copies at the defendant's office or regular place of business with a competent person in charge.
The requirements are strictly construed, and the sheriff's return must show the diligent efforts at personal service first.
Service on a Corporation
For a domestic corporation, summons is served on specific officers, such as the president, managing partner, general manager, corporate secretary, treasurer, or in-house counsel. Service on the wrong person may be ineffective.
Extraterritorial Service
For a defendant who is a non-resident and not found in the country, extraterritorial service is allowed only in certain actions — such as those affecting the personal status of the plaintiff or property in the Philippines — and only by leave of court, through:
- Personal service abroad;
- Publication (with a copy sent to the defendant's last known address); or
- Other means the court directs.
Defective Service and Voluntary Appearance
If service is defective, the court does not acquire jurisdiction over the defendant, and any judgment against them may be void. However, the defendant's voluntary appearance (for example, seeking affirmative relief without objecting to jurisdiction) generally cures the defect and submits them to the court's jurisdiction.
Practical Takeaways
- Valid service of summons gives the court jurisdiction over the defendant — personal service is preferred;
- Substituted service (at the residence or office, strictly) is used only if personal service fails; corporations are served on specific officers;
- Extraterritorial service (for non-residents) is limited to certain actions by court leave — and defective service voids the judgment unless cured by voluntary appearance.
Frequently Asked Questions
Why is service of summons important? Because it vests the court with jurisdiction over the person of the defendant in an action in personam and notifies them of the case. Without valid service or voluntary appearance, the court cannot render a valid personal judgment.
What is the difference between personal and substituted service? Personal service is handing the summons to the defendant in person, which is preferred. Substituted service, used only if personal service cannot be made within a reasonable time, leaves copies at the defendant's residence or office with a qualified person, strictly following the rules.
How is a corporation served with summons? For a domestic corporation, summons is served on specific officers such as the president, managing partner, general manager, corporate secretary, treasurer, or in-house counsel. Service on the wrong person may be ineffective.
What happens if service of summons is defective? The court does not acquire jurisdiction over the defendant, and any judgment against them may be void. However, the defendant's voluntary appearance generally cures the defect and submits them to the court's jurisdiction.
