A medical certificate in Chennai is issued by a registered doctor who has examined you, in a set format, and it must carry the doctor’s registration number. For sick leave or a fitness-to-rejoin note, any registered medical practitioner can issue it. For a driving licence, the certificate is Form 1A, which a registered medical practitioner now issues electronically on the Sarathi portal. For a first government job, the appointing department names the grade of doctor or medical board it will accept.
There is no single office that issues all of these. You get them from your own doctor, a government hospital OP, or the medical board your employer names. The rules on what a valid certificate must contain come from the national code of medical ethics, which the Tamil Nadu Medical Council enforces for doctors registered in the state.

How to get the certificate
- Find out which certificate you need. Ask the employer, college or RTO for the exact format and who may sign it. A sick-leave note, a job fitness certificate and Form 1A are different documents.
- Choose the right doctor. For leave and general fitness, your treating doctor or a government hospital OP doctor. For Form 1A, a registered medical practitioner who has a Sarathi login. For a government post, the officer grade or medical board named in your appointment order.
- Go for the examination in person. Carry ID and reports. At government hospitals, OP runs from 7.30 am to noon on all days, according to the health department citizen charter.
- Let the doctor record your identity. The 2002 regulations require your signature or thumb impression and at least one identification mark on the certificate, and the doctor keeps a copy in a register.
- Check the details before you leave. A leave certificate should state the illness, the period of absence and the date it starts; a fitness certificate should say you are fit to resume. Check spelling, dates and the doctor’s registration number.
- For a driving licence, confirm the upload. Form 1A is to be issued electronically on the portal with your photograph, under rule 5 of the Central Motor Vehicles Rules, as a state transport order explains. Note the date: it is valid for six months.
- Keep a copy. Submit the original and keep a scan. Employers sometimes ask again at confirmation.
Which certificate, which doctor
| Certificate | Who issues it | Key rule |

| Government job joining | Doctor or medical board named by the department | Check the appointment order for the grade required |

A doctor who signs an untrue or misleading certificate can be removed from the medical register, under the 2002 professional conduct regulations.
Common mistakes
- Asking for a certificate without an examination. The doctor is putting their registration on the line, and the certificate can be rejected.
- Using a generic form when the employer has its own. Ask first; it saves a second visit.
- Getting Form 1A too early. It is valid for six months, so time it with your licence application.
- Accepting a certificate without a registration number. Clause 1.4 of the regulations requires it on every certificate.
If it goes wrong
If an employer rejects a certificate, ask in writing what format or signatory it needs. If a doctor refuses to give a certificate after examining you, ask why; a doctor can decline if you are not ill. If you are offered a certificate for money without an examination, do not take it: both the doctor and the user can face action. Complaints about a doctor’s conduct go to the Tamil Nadu Medical Council, Poonamallee High Road, phone 044-26265678. For general health information, the state’s 104 helpline runs round the clock.
If you have an ongoing condition that affects driving or work, discuss it frankly with the doctor; they are certifying your safety as well as your paperwork.
