By Whom Made

Nature of Service by an Authorized Server

Summons is a court process, so its service is an act done under the authority of the court and not a private act of the plaintiff. In an action in personam, valid service of summons is the ordinary mode by which the court acquires jurisdiction over the person of the defendant. In actions in rem or quasi in rem, summons primarily satisfies notice and due process, but the service must still be made in the manner and by the persons allowed by the Rules.

The rule on who may serve summons is therefore jurisdictional in effect. A complaint delivered by a person with no authority from the Rules or from the issuing court does not become valid service merely because the defendant actually learned of the case. Actual notice may explain why a defendant appeared, but it does not supply the missing authority of the server when jurisdiction over the person is properly objected to.

The clerk of court issues summons, but the clerk's issuance is distinct from service. Service is ordinarily performed by the sheriff, the deputy sheriff, or another proper court officer. For justifiable reasons, the court issuing the summons may authorize a suitable person to serve it.

Ordinary Servers of Summons

The sheriff and deputy sheriff are the primary officers charged with serving summons because service of process is part of their official ministerial duties. Once summons is issued and placed in their hands, they do not pass on the sufficiency of the complaint, the merit of the claim, or the wisdom of suing the defendant. Their function is to serve the process, observe the required mode of service, and report what was done.

An "other proper court officer" refers to an officer of the court who is legally or officially tasked to serve process, such as a process server or another court employee duly assigned to that function. The phrase does not convert every court employee into a process server. The person's authority must arise from official duty, lawful designation, or a valid direction of the court.

Because summons is coercive court process, a sheriff or proper court officer may not casually delegate service to a messenger, driver, security guard, courier, or party representative. Assistance in locating an address or identifying a defendant is different from the legal act of serving summons. The person who performs the service must himself or herself be authorized.

Authorization of a Suitable Person

The court may authorize a suitable person to serve summons only for justifiable reasons. The exception prevents delay or failure of service when ordinary court channels are inadequate, unavailable, impracticable, or have already failed despite reasonable effort. The exception is not a standing license for a litigant to create a private process-serving system.

A suitable person must be capable of making a reliable, lawful, and accountable service of court process. Suitability involves competence, availability, ability to identify the defendant or proper recipient, willingness to execute a truthful proof of service, and absence of circumstances that make the service inherently unreliable. A person connected with a party is not automatically the server merely because the party prefers convenience; the controlling fact is the court's authorization.

The authority must come from the court issuing the summons. A private instruction by counsel, a request by a sheriff, a notation in a transmittal letter, or the defendant's later receipt of the papers does not by itself create authority. The safer and proper practice is for the authority to appear in the record before service is attempted, identifying the person authorized and the summons or defendants covered.

Special authority is limited by its terms. If the court authorizes a named person to serve one defendant, that person cannot serve other defendants unless the order covers them. If the order authorizes service at a particular address or under a particular mode, the server must obey that limitation. Authority to serve summons is not authority to alter the contents of summons, extend the period to answer, negotiate the claim, or receive pleadings for the court.

Authority Is Separate from the Mode of Service

The person serving summons and the method of service are separate requirements. Service by an authorized sheriff may still be invalid if the sheriff leaves the summons with a person who is not a proper recipient. Conversely, delivery to the correct defendant or corporate officer may still be ineffective if the delivery was made by someone with no authority to serve summons.

For an individual defendant, the authorized server must first follow the rule on personal service unless the Rules permit another mode. If substituted service is used, the server must be the authorized server and must be able to state the efforts made to serve personally, the reason personal service was not completed within a reasonable time, the place where summons was left, and the identity and relation of the person who received it.

For a corporation, partnership, association, or other juridical entity, the server's authority does not dispense with the rule on the proper recipient. Service must be made upon the officers or agents allowed by the Rules. A sheriff's badge does not validate service on a person who is not a designated or legally acceptable recipient, and a proper corporate officer's receipt does not cure service made by an unauthorized private person if jurisdiction is timely challenged.

Where the Rules provide special arrangements for particular defendants, such as prisoners, minors, incompetents, public corporations, foreign private juridical entities, defendants whose identity or whereabouts are unknown, or defendants outside the Philippines, the special rule on the recipient or mode must be read together with the rule on an authorized server. The special mode does not erase the basic requirement that the act of service be traceable to authority granted by the Rules or by the court.

Proof and Return by the Server

The server must make a return or proof of service because the court cannot rely on guesswork to determine whether jurisdiction over the defendant has been acquired. The proof should state the date, place, manner of service, documents served, and the name and relevant capacity of the person who received the summons. These facts allow the court and the parties to test both the authority of the server and the legality of the mode used.

A sheriff's return is an official report of service and is generally accorded weight because it is made in the performance of official duty. That weight is not absolute. A return that is vague, inconsistent, facially defective, or contradicted by competent evidence may fail to establish valid service.

When service is made by a person other than a sheriff or regular court officer, proof ordinarily requires an affidavit or equivalent sworn statement showing that the person was authorized and describing the service made. The affidavit should not merely conclude that service was valid. It should narrate the facts showing the server's authority, the identity of the recipient, the manner of delivery, and the compliance with any limits imposed by the court's order.

The return is not the source of jurisdiction; valid service is. A return can evidence service, but it cannot cure a service that was never authorized or never made in the required manner. At the same time, defects in the wording of a return may be corrected when the underlying service was in fact valid and the correction does not prejudice the defendant's right to contest jurisdiction.

Consequences of Unauthorized Service

Unauthorized service of summons does not bind the defendant to answer, does not start the period to file a responsive pleading, and does not support a valid declaration of default. If the court proceeds without valid service and without voluntary submission by the defendant, its judgment is vulnerable for lack of jurisdiction over the person of that defendant.

The defect is personal to the defendant and may be waived. Voluntary appearance is equivalent to service of summons because the defendant submits to the court's jurisdiction. However, an appearance made precisely to object to jurisdiction over the person, or to seek relief consistent with that objection, does not amount to waiver merely because the defendant came before the court for that limited purpose.

When service by an unauthorized person is discovered, the proper course is not to treat the defective act as harmless notice. The court may direct valid service by the proper officer, issue alias summons when appropriate, or authorize a suitable person upon a showing of justifiable reasons. Jurisdiction over the person is acquired prospectively through valid service or voluntary appearance, not retroactively by treating an unauthorized delivery as if it had been court process.

Operational Distinctions

• Issuance is not service. The clerk issues summons under the seal of the court, while the authorized server delivers it in the manner required by the Rules.
• Authority is not convenience. A party's difficulty in arranging service does not by itself authorize private service; the court must find a justifiable reason and authorize a suitable person.
• Receipt is not always valid service. The defendant's physical receipt of papers matters, but the court still asks whether the person who delivered them had authority and whether the mode used was allowed.
• Official status is not unlimited power. A sheriff must still serve the proper person, at the proper place, and through the proper mode.
• Special authorization is case-specific. A person authorized in one case, for one defendant, or for one attempt does not acquire general authority to serve summons in other cases.

The controlling principle is that service of summons must be both official in source and lawful in execution. The server must be one recognized by the Rules or specifically authorized by the issuing court, and the service must be proved by facts showing that the defendant was reached through a valid exercise of court process.
