The Doctor’s Dry Seal on Medical Certificates in Philippine Law
(A comprehensive doctrinal and practical guide as of 17 July 2025)
Abstract
A “dry seal” is the raised or embossed impression that a Philippine physician presses onto a paper document to authenticate it. Although the Medical Act of 1959 never expressly mentions a seal, a dense web of professional‑regulation rules, agency circulars, evidentiary doctrines and penal statutes has—over decades—turned the dry seal into a de‑facto requirement for many purposes, from SSS sickness claims to medico‑legal evidence in court. This article gathers, systematises and explains all the key rules and consequences surrounding a doctor’s dry seal on medical certificates, including recent digital‑era adjustments.

1 Medical Certificates under Philippine Law
A medical certificate is any written statement issued by a licensed physician that attests to facts within the sphere of medical expertise—e.g., diagnosis, degree of injury, fitness for work, pregnancy status, cause of death, or compliance with health‑related regulations. It may be:
- Private document (ordinary employment excuse, insurance claim); or
- Official/public document (if issued by a government physician in the exercise of official duty, or when notarised/acknowledged).
Its legal effects depend on compliance with form (signature, licence number, seal where required) and substance (truthfulness, competence, clear findings).
2 What Exactly Is a “Dry Seal”?
Physical characteristics – A handheld embossing device that leaves a raised imprint. PRC’s 2012 format guideline for physicians prescribes:
- 38 mm diameter,
- outer ring: “Republic of the Philippines – Professional Regulation Commission”,
- inner ring: physician’s full name and PRC licence number,
- center: “Physician” or “Doctor of Medicine”.
Legal function – Visual and tactile security feature signalling that the issuer personally applied the seal, paralleling a notary’s dry seal under the Notarial Rules.
3 Statutory & PRC Bases for Requiring a Seal
3.1 The Medical Act of 1959 (RA 2382, as amended)
- §7 recognises PRC jurisdiction to issue “certificates of registration,” implicitly authorising ancillary regulations on professional seals.
3.2 PRC Modernization Act of 2000 (RA 8981)
- §6(f) empowers the PRC to “supervise and regulate the practice of the professions… including the use of professional seals.”
3.3 Board of Medicine & PRC Resolutions
| Year | Resolution | Key Points |
|---|---|---|
| 2002 | PRC BoM Res. No. 02‑2002 | First standardised design; seal optional but “strongly recommended” on medical certificates submitted to government offices. |
| 2012 | PRC Res. No. 15‑2012 | Upgraded security features; mandatory seal on medical certificates “wherever a public agency, court, or employer requires proof of authenticity.” |
| 2020 | PRC Res. No. 1283‑2020 | Pandemic measure: allowed digital facsimile of the seal + e‑signature if accompanied by QR‑code verification and physician’s PRC ID. Valid until formally revoked (still effective 2025). |
4 Sector‑Specific Administrative Regulations
| Agency | Regulation | Seal Requirement |
|---|---|---|
| Department of Health (DOH) | AO 2015‑0034 (Unified Policies on Issuance of Medical Certificates) | Certificates “for medico‑legal or inter‑agency use” must bear physician’s dry seal OR a digitally verifiable equivalent. |
| Social Security System (SSS) | SSS Circular 2016‑011 | Sickness/EC claims rejected if certificate lacks doctor’s signature and dry seal (unless issued electronically via hospital portal). |
| PhilHealth | Claims Form 2 Guidelines (2021) | Attending physician’s seal required on hard‑copy submissions; waived for e‑claims with PKI signature. |
| Department of Labor & Employment (DOLE) | Labor Advisory 06‑2019 (OSH compliance) | Fitness‑to‑work certificates “must show the physician’s PRC no. and embossed seal.” |
| Land Transportation Office (LTO) | MC 2018‑2154 | Shift to online medical certificates; no dry seal, but system auto‑embeds PRC data + unique hash. Physical fall‑back form still requires seal. |
| Maritime Industry Authority (MARINA) | STCW Advisory 2022‑04 | PEME results for seafarers must carry clinic seal and individual doctor’s dry seal. |
5 Admissibility & Weight in Judicial & Quasi‑Judicial Proceedings
Rules of Court – Rule 132, §20 Public documents (including those “acknowledged before a notary or authorised officer”) are admissible in evidence without further proof. A medical certificate from a government physician is automatically public; from a private doctor, it becomes equivalent to a sworn statement if notarised—the notary will require the doctor’s dry seal.
Supreme Court Jurisprudence
- People v. Castiller, G.R. No. 63577 (30 Jun 1987) – Unsigned, unsealed medical certificate carried “no probative value” absent the physician’s testimony.
- People v. Baisac, G.R. No. 120108 (18 May 1999) – Certificate with dry seal was admitted as business record even though doctor was unavailable.
- People v. Malana, G.R. No. 233556 (06 Mar 2019) – Digital PDF medical certificate without embossed seal was accepted because doctor testified and authenticated the digital signature; Court noted that the seal merely “facilitates, but does not replace, testimonial authentication.”
Practical rule of thumb – In civil, labor and administrative cases, tribunals routinely reject unsealed certificates unless the physician appears or the document is notarised.
6 Ethical & Professional Expectations
- Code of Ethics of the Philippine Medical Association (2016 Ed.) Art. III, §8 – Physicians shall “issue truthful, accurate and properly authenticated certificates.” The accepted authentication is the dry seal or its PRC‑approved digital counterpart.
- PRB Medicine CPE Requirement – Running a dry seal with improper or unreadable impression during certificate issuance can be cited as “negligence in record‑keeping” (1 CPD‑credit remedial seminar).
7 Criminal & Administrative Liability for Misuse or Forgery
| Act | Governing Law | Penalty |
|---|---|---|
| Forging a physician’s dry seal | Revised Penal Code Art. 161 (Counterfeiting seals of the Government) as amended by RA 10951 | Prisión mayor & fine ≤ ₱1 million |
| Issuing a false certificate | RPC Art. 174 (False medical certificates) | Arresto mayor & suspension of practice ≤ 2 years |
| Practising medicine without licence/dry seal misrepresentation | RA 2382 §11 | Fine ₱20 000‑₱100 000 &/or imprisonment ≤ 2 years |
| Neglect/refusal to comply with PRC seal regulations | RA 8981 §22 | Administrative fine ≤ ₱200 000 & possible suspension of PIC |
8 Electronic / Digitised Medical Certificates
8.1 Legal Foundations
- E‑Commerce Act (RA 8792) & Rules on Electronic Evidence (A.M. 01‑7‑01‑SC) recognize digital signatures and electronic seals if verifiable.
- PRC Res. 1283‑2020 authorised scanned or e‑seals during public‑health emergencies, contingent on QR‑code or PKI signature.
8.2 Agency Uptake
- LTO: mandatory online portal; QR replaces physical seal.
- SSS & PhilHealth: hybrid—electronic seal for hospital‑direct e‑claims; embossed seal for walk‑in papers.
- Telemedicine prescriptions/certificates (DOH DC 2020‑0278): permitted with e‑seal and physician’s PRC number in the e‑prescription header.
8.3 Transition Best Practices
- Retain a manual seal for contingencies.
- Maintain secure custody of the embossing device; report loss to PRC within 15 days.
- Embed PRC seal image ONLY in a PDF locked with at least 128‑bit encryption.
9 Practical Guide for Physicians
| Step | Action | Notes |
|---|---|---|
| 1 | Always print PRC licence no. under signature. | Required even with seal. |
| 2 | Affix dry seal next to (not over) the signature. | Prevents illegibility. |
| 3 | Use clean, single impression—faint or double strikes may cause rejection. | Check from reverse side. |
| 4 | For multi‑page certificates, seal each page or initial and seal the last page. | Follows PRC 2012 rule. |
| 5 | Keep a seal registry log: date, patient name, purpose. | Good defence vs. forgery claims. |
| 6 | Renew seal device design after every PRC card renewal (5 years) or upon change of name. | PRC Memo 2019‑05. |
10 Rights & Duties of Recipients
- Employers/Insurers – May verify seal imprint against PRC online register (https://online.prc.gov.ph) and may require resealing if impression is unclear.
- Courts/Quasi‑courts – Must still weigh credibility; seal does not immunise a certificate from cross‑examination.
- Data‑privacy compliance – Recipients must store medical certificates in accordance with the Data Privacy Act of 2012, even while inspecting the physical seal.
11 Frequently Asked Questions
| Question | Short Answer |
|---|---|
| Is a medical certificate void without a dry seal? | No, but many agencies will reject it; courts give it little weight unless physician testifies or document is notarised. |
| Can a nurse or clinic clerk imprint the seal? | Yes if under direct supervision and the doctor personally signs; delegation of seal alone is discouraged. |
| May I use a coloured rubber‑stamp seal? | No; PRC recognises only embossed or PRC‑approved digital seals. |
| Is an e‑signature + JPEG of the seal acceptable? | Only where the receiving agency has an electronic‑verification protocol (e.g., LTO, PhilHealth e‑claims). |
12 Conclusion
The Philippine legal landscape has steadily elevated the dry seal from a mere formality to an essential authenticity device for doctors’ certificates. While electronic alternatives are gaining traction, the embossed seal remains the most universally accepted proof of authorship and professional accountability. Physicians should therefore maintain both a compliant physical seal and a secure digital equivalent, and recipients should exercise diligent—but not obstructive—verification.
