How to get a medical certificate in Portugal

A medical certificate in Portugal (atestado médico) is an official document issued by a registered doctor confirming that you are ill, injured, or medically unfit for work, study, travel, or physical activity.

Medical certificates are commonly required for:

  • Employer sick leave approval under Portuguese labour law
  • Subsídio de Doença claims through Segurança Social
  • School or university absences and exam deferrals
  • Fitness clearance for gyms, sports clubs, or work duties
  • Travel purposes such as fit-to-fly certificates
  • Insurance or legal verification

Confusion often arises because:

  • Some employers ask for certificates from Day 1
  • Segurança Social requires certificates from Day 4
  • Doctors decide how much medical detail is disclosed

GetMedicalCertificate.com simplifies the entire process by providing fast, legally compliant medical certificates from Ordem dos Médicos (OM)-registered doctors, without long public health (SNS) waiting times that can delay pay or benefits.

What Is a Medical Certificate in Portugal?

In Portugal, a medical certificate (atestado médico) is a formal medical document issued by a doctor registered with the Ordem dos Médicos (OM). It explains how a health condition affects your ability to work, study, or carry out activities.

It may state:

  • “Not fit for work”
  • “Fit for work with restrictions”
  • “Fit to return from a specific date”

Unlike informal doctor’s notes, a valid medical certificate must include:

  • OM registration number
  • Doctor’s signature
  • Consultation date and duration of incapacity

GetMedicalCertificate.com provides printable and e-submittable PDFs that meet the same standards as in-person certificates, issued through secure online consultations.

  • Employees must notify absence on Day 1

Self-Certification vs Doctor-Issued Certificate

Self-Certification

  • Covers short absences (1–3 days)
  • No medical proof initially
  • Not valid for Segurança Social
  • Can be challenged if patterns appear

Doctor-Issued Certificate

  • Required from Day 4
  • Mandatory for subsídio de doença
  • Strong legal protection
  • Prevents pay disputes

GetMedicalCertificate.com ensures a smooth transition when self-certification ends.

Medical Certificates for Illness Benefit (Segurança Social)

To receive subsídio de doença, you must submit a medical certificate from Day 4 of incapacity.

Key points:

  • Daily payment approx. €0.55–€0.80 (based on contributions)
  • Maximum duration up to 1095 days in severe cases
  • Certificates must be renewed weekly or fortnightly
  • Missing documents cause payment suspension

GetMedicalCertificate.com issues Segurança Social-compatible certificates, helping maintain uninterrupted benefits.

Statutory Sick Pay (SSP) and Medical Certificates

Portuguese statutory sick pay works in stages:

  • Day 4–30: ~75% of salary
  • Later stages: employer + Segurança Social split (60–90%)

A valid medical certificate is the trigger for all payments.
Without it, benefits stop.

Fitness-to-Work & Return-to-Work Certificates

After illness or injury, doctors may certify you as:

  • Fully fit
  • Fit with restrictions (reduced hours, no lifting, lighter duties)
  • Still unfit

Phased returns are common and legally supported.
