Overview

A “medico-legal certificate” (often called a “medico-legal report” or “medical certificate for legal purposes”) is a written medical document describing injuries, findings, and clinical impressions—prepared specifically to support a legal proceeding (criminal, civil, administrative, labor, insurance, or protective order matters).

In Philippine practice, there is generally no single law that sets a fixed “expiration date” for a medico-legal certificate. Instead, its usefulness and acceptability depend on (1) the purpose for which it will be used, (2) how timely the examination was done, (3) whether it can be properly authenticated in the forum where it is presented, and (4) the time limits for filing the case (prescription and procedural deadlines).

So the more accurate way to think about “validity” is:

The certificate does not typically “expire” by law, but
Your right to use it effectively may be limited by deadlines, and
The evidentiary weight can weaken as time passes, especially if the exam was delayed or injuries have healed.

1) What a Medico-Legal Certificate Is (and Is Not)

What it is

A medico-legal certificate is a medical document intended for legal use, commonly containing:

Patient identifiers and the date/time of consultation/exam
History of the incident (often based on the patient’s narrative)
Physical findings (location, size, nature of injuries)
Ancillary results (imaging, labs, photographs if taken)
Clinical assessment
Opinion relevant to legal classification (e.g., estimated period of treatment/incapacity)—particularly important in physical injuries cases
Physician’s name, license number, signature, facility details

It may be issued by:

Government hospitals
Local health offices
PNP Crime Laboratory / medico-legal units
NBI medico-legal services
Private hospitals/clinics (often used, but may require stronger authentication steps)

What it is not

It is not automatically a “pass” to file a criminal case (a complaint can often be initiated even without it, though proving injuries becomes harder).
It is not the same as a routine “medical certificate” for school/work, though people use the terms loosely.
It is not guaranteed to be accepted by every agency without meeting that agency’s documentary requirements.

2) The Core Answer: Does It Have a Legal Expiration Date?

No universal statutory expiry

In general Philippine legal practice, a medico-legal certificate does not come with a single, nationwide legal validity period (like “valid only for 30 days”). If you see a “valid for ___ days” stamp, it is usually:

An internal administrative rule of a hospital/clinic for document requests, or
A purpose-specific requirement (e.g., employment/insurance processing), not a rule that controls court admissibility.

What actually controls “how long you can use it”

Four practical/legal factors control how “valid” it is in real life:

Case filing deadlines (prescription)
Purpose-specific deadlines (e.g., agency or employer cutoffs)
Evidentiary requirements (authentication, testimony, document rules)
Medical dynamics over time (injuries heal; classification can change)

3) Prescription: The Deadline That Matters Most

If you’re asking “until when can this be used to file a case?”—the key is the prescriptive period of the offense.

Physical injuries cases (Revised Penal Code)

For injuries, the medico-legal certificate often supports the classification (e.g., slight, less serious, serious physical injuries) by stating the period of treatment/incapacity. The prescriptive period depends on how the law classifies the offense and its penalty.

Some minor offenses can prescribe quickly (light offenses can be as short as two months).
More serious offenses have longer prescriptive periods.

Practical implication: Even if your certificate remains “usable,” your ability to file a criminal complaint can be lost if you wait beyond prescription.

When does prescription stop running?

As a practical matter, initiating the complaint in the proper forum (e.g., filing with the prosecutor’s office, filing in court when appropriate, or other legally recognized steps) can affect prescription. Because this area can turn on details (offense, dates, where/how filed), it’s safest to treat deadlines as urgent.

4) “Timeliness” of the Exam: Why People Think It Expires

Many people are told things like “get a medico-legal within 72 hours” or “within 24 hours.” Usually, that is medical and evidentiary practicality, not a legal “expiry.”

Why earlier is better

Bruises, swelling, abrasions, and tenderness can fade.
Some injuries become less visible.
For sexual violence cases, certain findings and samples are time-sensitive.

If you got examined late

A delayed medico-legal certificate can still be valuable, but:

The doctor may document fewer visible signs.
The defense may argue the injuries could be from another cause/time.
The probative value may be challenged.

Bottom line: The certificate doesn’t “expire,” but delay can reduce evidentiary strength.

5) Court Use: Admissibility vs. Weight

There are two separate questions:

A) Can it be admitted as evidence?

A document generally needs to be identified and authenticated according to evidentiary rules. In practice:

If the doctor testifies, the certificate is usually straightforward to present.
If the doctor is unavailable, admission can be more complicated (depending on whether it qualifies under exceptions like official records, business records, etc., and depending on court rulings and objections).

Government-issued medico-legal documents are often easier to treat as official/regular records, but litigation still turns on objections and proper foundation.

B) How much will the court believe it?

Even if admitted, the judge will weigh:

How soon after the incident the exam occurred
Completeness and clarity of findings
Consistency with other evidence (photos, witness accounts, CCTV, messages)
Whether the examiner was credible and available for cross-examination

So a medico-legal certificate can remain usable years later in a long-running case, but the court may ask: Was it timely? Is it reliable? Is it corroborated?

6) Special Contexts Where “Validity” Is Commonly Misunderstood

A) VAWC (R.A. 9262) and protection orders

For protection orders, immediate safety is the focus. A medico-legal certificate can help show harm, but protective relief often doesn’t depend solely on it. Agencies may still request recent medical documentation for certain actions, but that’s procedural rather than a fixed nationwide “expiry.”

B) Sexual violence cases

Time matters because:

Some physical findings heal quickly
Forensic collection windows may exist in practice

A medico-legal report made later can still support the narrative, but it may not capture time-sensitive findings.

C) Employment, school, and HR requirements

Some institutions impose “valid only for X days” rules for administrative processing. That does not automatically bind courts or prosecutors, but it can affect whether HR/benefits will accept the document without re-issuance.

D) Insurance claims

Insurers often impose reporting and submission deadlines in policies. A medico-legal certificate might be requested within a certain window, not because it “expires,” but because the claim process does.

7) Initial vs. Final Medico-Legal Certificate (and Why It Matters)

In injury cases, it’s common to have:

Initial certificate: documents findings at first consult and gives an initial estimate of treatment/incapacity.
Follow-up / final certificate: issued after healing or re-evaluation, sometimes adjusting the number of days of treatment/incapacity.

Why this matters:

The legal classification of physical injuries can hinge on the final period of incapacity/treatment.
If complications arise, the initial estimate may change.
Prosecutors and courts often prefer a final/updated medical assessment when classification is contested.

Tip: If your injuries required continued treatment, ask whether a final medical certificate is appropriate before formal case classification is locked in.

8) Practical Guidance: What To Do So Your Certificate Stays “Usable”

Act quickly on filing
- If you intend to pursue a case, treat it as time-sensitive because of prescription and evidentiary decay.
Keep the original and request certified copies
- Preserve the original document in good condition.
- If issued by a facility, ask for certified true copies if you need to submit to multiple offices.
Gather corroborating evidence
- Photos of injuries (dated, ideally taken over several days)
- Receipts, prescriptions, imaging results
- Messages, CCTV leads, witness details
Document continuity
- Follow-up consultations create a clearer medical timeline and can support credibility.
Consider where you get examined
- Government medico-legal units (PNP/NBI/government hospitals) can be more standardized for legal proceedings.
- Private physicians’ certificates can still work, but authentication and testimony logistics matter.

9) Common Questions

“My medico-legal is more than a month old. Is it still valid?”

Usually yes, in the sense that it remains a document of what was found on the exam date. What may change is:

whether an agency will accept it without re-issuance, and
how persuasive it is if the exam was not close in time to the incident.

“Police said it’s valid only for 3 days—is that true?”

Commonly this refers to recommended timing for examination (for better documentation), not a universal legal expiry rule.

“Can I file a complaint without a medico-legal certificate?”

Often yes, but it may be harder to prove injuries and classify the offense properly. Many complainants still obtain it early to strengthen the case.

“Do I need the doctor to testify?”

It depends on how the document is offered, what objections are raised, and what evidentiary pathway is used. As a practical matter, having the examining doctor available generally reduces risk of exclusion or diminished weight.

Key Takeaways

No single Philippine law sets a universal “expiration date” for medico-legal certificates.
The real time limit is usually case filing deadlines (prescription) and purpose-specific administrative requirements.
The longer the delay between incident and examination, the more the evidentiary weight may be challenged.
For injuries, an updated or final medical certificate may be important because legal classification can depend on the ultimate period of treatment/incapacity.
Preserve the document, act promptly, and support it with other evidence.

If you want, share the context (e.g., physical injuries, VAWC, workplace incident, school requirement, insurance claim), and the date of the incident versus the exam date—and I’ll map out the most relevant deadlines and the most practical next steps for that specific scenario.
