Medical certificates, also commonly called sick leave certificates, may seem just like another simple administrative task for doctors. However, there are many legal, ethical and professional issues you need to consider when issuing one to a patient. 

A medical certificate is most commonly issued to an employee to show absence from work due to illness or medical condition, or because of carer obligations. Under the Fair Work Act, the certificate can be requested by an employer as evidence to support the issuance of sick leave payment to an employee. 

Doctors can face challenges with their dual role as an advocate for the patient and assessor for an employer. Medical certificate rules are outlined in the Australian Medical Association’s (AMA)’s Guidelines for Medical Practitioners on Certificates Certifying Illness .

According to the Medical Board of Australia, for notifications received between 1 July 2023 and 16 June 2026, when regulatory action was taken, the concerns raised typically related to:

Inadequate clinical assessment and issuing certificates without appropriate consultation (including telehealth contexts);Accuracy and integrity issues.Doctor’s responsibilities when issuing a medical certificate

Nerissa Ferrie, Senior Manager, Medico Legal Advisory at MDA National Insurance says, “Doctors should act in accordance with the Medical Board of Australia’s Code of Conduct and respect the trust with which the public views the medical profession. Doctors should only put their signature to documents they believe to be true and accurate, and the clinical notes should support the certification.”

A medical certificate must be based on a medical examination and assessment of patient history, information provided by the patient, and on facts known to the doctor. 

Doctors also need to remain impartial. As AMA’s guidelines specify, doctors who deliberately issue a false, misleading or inaccurate certificate could face disciplinary action under the Health Practitioner Regulation National Law. Doctors may also expose themselves to civil or criminal legal action. 

The patient trusts that the GP will maintain confidentiality, and only disclose personal information related to the medical certificate to a third party with the patient’s express consent or where required by law. A certificate should also not be forwarded to a third party without the patient’s consent.

What information should appear on a medical certificate?

AMA’s guidelines outline medical certificate requirements:

Name and address of medical practitioner issuing the certificate;Patient name;Date of medical examination;Date of issue of certificate: Under no circumstances can this be breached and the certificate can not be backdated; Date(s) the patient is or was unfit for attendance. Dr Rudge says, “The period you certify can reach into the past — but only as far as you can clinically justify and have documented;”Specific details of the condition that is being certified; andAddress the certificate to the party requiring the certificate.

The certificate should also be legible so that a non-medical member can read and understand it. 

Document clinical findings in patient record

As Ferrie says, “The clinical notes are the best source of truth, so anything that relates to a doctor writing a certificate should be evidenced in, and supported by, the patient’s clinical notes.” Keep a copy of the certificate in the patient’s medical record.

The University of Sydney’s Dr Christopher Rudge is Lecturer and Deputy Director of Sydney Health Law (Law School). He refers to a case that underlines the importance of accurate, clear and thorough documentation. “Doctors have been sanctioned over a certificate that was entirely honest and accurate. 

“In Fitzpatrick [2023] VCAT 517 the Board alleged no dishonesty and no false certificates, yet a well-regarded rural GP was found guilty of professional misconduct, reprimanded, and placed under two years of record-keeping audits, for taking ‘unacceptable shortcuts.’ These included issuing certificates that included no documented assessment or clinical justification, undated certificates, dates reaching months into the past, one filled in by the patient themselves, certificates for a relative without a recorded consultation, and one running six months into the future without planned follow-up or review.”

Challenging medical certificate scenarios GPs may face

There are a variety of situations whereby a doctor may need to balance the requests between employees and employers.

Employee requests a medical certificate for dates different to visit 

Patient says they have been unwell before visit 

A doctor may issue a certificate with dates prior to the examination visit, only if after careful patient examination and in their careful and professional clinical judgement can conclude that the patient was unwell for the symptoms they present or say they had. 

Patient informs of condition that has resolved before visit

According to Avant, certificates that purport to confirm an illness or period of incapacity that has resolved before the consultation are a common cause of complaints to regulatory bodies.

It is not legitimate to provide a certificate for that period as there is no condition for which the doctor can examine and provide findings on. 

Patient with ongoing illness 

For illnesses that started prior to the doctor visit and is ongoing, the date should show the period for which the patient was unfit for work, with Avant advising wording such as, “Based on the history provided and my examination…”.

Employer or third party seeks further information or verification 

When a doctor is approached by an employer:

Verify the party’s identity. Ask for a copy of the certificate, view it and confirm if the certificate is genuine and was completed by the doctor. No other information should be provided to the third party without patient consent. 

A medical certificate cannot be clinically justified

Explain to the patient the reasons and document this in their medical record. If appropriate, the doctor may offer alternative options, as Avant suggests, such as issuing a certificate for a shorter period than requested or offering to review the patient again if their condition persists. 

Vagueness to get around this can constitute misconduct, as Dr Rudge explains, “In the recent case of Foong[2026] NSWCATOD 29 the GP wrote “confidential medical condition” not to protect privacy but, on the practitioner’s own admission, because the real basis fell outside the exemption criteria for COVID-19 mandates and would have been rejected for the specific purpose the certificate was issued for if the truth was disclosed.”

Telehealth medical certificate services

Doctors providing online medical certificate services must be honest, ethical and trustworthy, only signing documents they believe to be accurate. As the Medical Board of Australia Telehealth consultations with patients guidelines state, issuing a medical certificate requires medical judgement and is providing healthcare. 

The Medical Board of Australia strongly recommends against providing medical certificates where there has been no examination or real-time discussion with the patient. In most of these cases, their indemnity insurance will not cover doctors. 

Conclusion 

Issuing a medical certificate is an administrative task as much as it is providing a medical service. To abide by the Medical Board’s Code of Conduct, doctors should only issue one if after careful clinical examination, judge that the medical certificate is true and clinically justifiable. However, it also requires honest, accurate, clear and complete documentation. 

As Dr Rudge says, “You can do everything honestly and still be sanctioned. The risk in issuing a certificate isn’t whether the patient was sick — it’s whether you can show the assessment and the record behind it.”

Summary of Key Points A medical certificate is a legal document and doctors need to base their decision to issue one only after they have conducted a clinical examination, together with information from the patient, and in their professional, clinical judgement deem the patient was unfit for work due to a medical condition. Doctors should only put their signature to documents they believe to be true and accurate, and the clinical notes should support the certification.Doctors may need to balance the competing requests between employers and third parties with those of employees. It’s important to maintain confidentiality and not release information to third parties without patient consent. Clear, accurate, complete, truthful documentation can help protect doctors against the risk of notifications, complaints, legal action or professional conduct proceedings.FAQs 

What if patient alters medical certificate?

Discuss this with the patient, although this may affect their ongoing relationship with the patient.

Under what circumstances can a doctor decline to issue a medical certificate?

Ferrie says a GP can refuse to provide a certificate if they don’t genuinely believe the reason for the certificate is truthful, or if it’s outside their scope of practice. 

Can a doctor write a medical certificate for family and friends?

As per the Code of Conduct , doctors should not be in a treating relationship with anyone close to them, including friends, family, or anyone they work with. 

How should a doctor handle conflicts between patient confidentiality and employer requests?

Do not release any information to the employer without the patient’s consent, and the doctor can explain this to the employer.

The third party should recognise the right of individuals to keep details of their medical condition confidential. For example, employers should not expect to see a diagnosis on the employee’s certificate unless in certain circumstances where it’s legally required.

Still, some patients may request doctors withhold other types of information on a certificate. The Medical Council of NSW recommends that the doctor explain to the patient that the information provided may not be sufficient for the employer to accept the certificate for sick leave. 

What are a doctor’s obligations if an employer or patient disputes a certificate they have issued?

First check the identity of the third party, ask for a copy of the certificate they have received, and then confirm if the certificate is genuine and completed by themselves.

If a patient disputes the certificate, refer to AMA’s guidelines. The RACGP recommends referring to the Australian Medical Board of Australia’s Code of Conduct and contacting their MDO when in doubt.
