In the public service, retirement does not occur automatically. The employee must submit a written request to their employer administration several months before the desired cessation date. This letter, distinct from the pension liquidation request sent to the retirement fund, must adhere to specific rules regarding format and deadlines that vary depending on the sector (State, territorial, hospital).
Differences between the letter to the employer and the liquidation request
Confusion is common: many employees believe that a single letter is sufficient. In reality, two parallel processes are necessary. The first is a letter addressed to the hierarchical authority (establishment director, HR director, secretary general) to inform them of the intention to cease functions on a specific date. The second is the pension liquidation request, submitted to the competent fund (State Retirement Service for State employees, CNRACL for territorial and hospital employees).
The letter to the employer does not have an official required form. It takes the form of a free letter, sent by registered mail with acknowledgment of receipt. The liquidation request, on the other hand, increasingly goes through an online process (ENSAP for State employees, personal CNRACL space for others). Writing a retirement request letter for the public service correctly remains the first step, the one that triggers the administrative processing on the employer’s side.
Once informed, the employer forwards the file with supporting documents to the retirement fund. In the hospital public service, it is explicitly the employee’s responsibility to take the initiative: no automatic reminder is sent by the establishment.
Deadline for sending and retirement date
The minimum deadline to be respected depends on the sector of the public service and the relevant fund. For the hospital and territorial public service, the common rule requires sending at least six months before the desired departure date. The employer then has a deadline to submit the complete file to the CNRACL, usually three months before the departure.
For State employees, the departure request must also be anticipated by several months, allowing time for the State retirement service to process the file and calculate the pension. A late submission can delay the effective liquidation date and create a period without income or pension.
Departure date and birth on the first day of the month
An often-overlooked administrative detail: employees born on the first day of a month reach the legal age the day before, that is, the last day of the previous month. This nuance can shift the date of removal from the payroll by one month and thus the date of pension payment. Checking this point before setting the date in the letter avoids a calendar mismatch.
Mandatory content of the retirement request letter
The letter does not need to be long. However, it must contain a core of information that the administration expects to open the file without unnecessary back-and-forth.
- Full identity (name, first name, date of birth) and social security number, increasingly systematically required by funds and HR services for quick processing of the file
- Grade, step, current assignment, and employer administration
- Desired cessation date, clearly stated (for example: “I wish to exercise my retirement rights starting from September 1, 2026”)
- Explicit mention of the request for removal from the payroll or end of contract for contractual employees
- Contact details (phone, email) for file follow-up
The subject of the letter must be clear: “Request for retirement” or “Request for retirement”. Any vague wording (“I wish to consider my departure”) risks not being treated as a firm request.
Documents to attach with the letter
The letter alone is not sufficient to constitute the file. The employer will generally request a copy of the identity document, an updated career statement (available on the info-retraite.fr portal), and, if applicable, supporting documents related to bonuses (children, military service, periods of secondment). Gathering these documents before sending the letter speeds up processing.
Typical formulation example for a territorial or hospital employee
Here is the structure of a functional letter, without superfluous wording:
At the top: name, first name, address, social security number, grade, and assignment. The recipient is the director of the establishment or the territorial authority. The subject mentions “Request for retirement.”
The body of the letter consists of three paragraphs. The first indicates the intention to exercise retirement pension rights starting from a specific date. The second specifies that the employee is available to provide any additional documents necessary to complete the file. The third formulates the request for removal from the payroll on the same date.
Handwritten signature, date, mention “registered letter with acknowledgment of receipt.” This format meets administrative requirements without falling into the convoluted formulations found in some online templates.
Common mistakes that delay the processing of the retirement file
The first pitfall is sending by regular mail. Without proof of receipt, no administrative deadline runs. Registered mail with acknowledgment of receipt protects the employee in case of disputes over the request date.
The second trap concerns employees who have contributed to multiple schemes (periods in the private sector before entering public service, for example). The letter to the public employer does not trigger the liquidation of rights acquired with the CNAV or Agirc-Arrco. A separate request to each scheme is necessary, even if the info-retraite.fr portal now simplifies this process by allowing a common entry point.
Finally, some employees confuse retirement request and progressive retirement request. Progressive retirement, which allows reducing working hours while receiving a portion of the pension, requires specific eligibility conditions (age, contribution duration, employer agreement on part-time work). The letter and procedure differ significantly from a definitive departure request.
Writing this letter remains a simple administrative act, provided that the deadline is respected, the correct recipient is identified, and the expected information is provided from the first submission. A precise letter, sent at the right time, avoids reminders and delays in liquidation.
