Every Indian company issues HR documents throughout the employment cycle. Some are statutory requirements. Others are standard practice that courts and labour tribunals expect to see. Most employers know the obvious ones. This reference covers all twenty, what each document is for, what it should contain, and where it sits in the employment timeline.

These four documents carry the employment into existence. Each has a distinct legal function. They are not interchangeable, and issuing one without the other leaves the employment relationship incompletely documented.
The offer letter is the first formal document in the hiring process. It conveys the proposed terms: job title, compensation, start date, and basic conditions. It is not yet a binding contract. The candidate can accept, negotiate, or decline. Once accepted, it becomes the basis on which the appointment letter and employment contract are drawn up. Inconsistencies between the offer letter and subsequent documents are a frequent source of expectation disputes during the first few months of employment.
The appointment letter is issued after the candidate accepts the offer. Unlike the offer letter, it is a binding document. It sets out the salary structure, working hours, leave entitlement, notice period, applicable policies, and the start of probation if relevant. Under the New Labour Codes effective November 2025, all employers are required to issue appointment letters. An extant practice in many SMEs of issuing only an offer letter is no longer sufficient to meet this requirement.
The employment contract is the governing legal document for the employment relationship. It covers everything the appointment letter addresses but in greater detail, and adds clauses on intellectual property, non-solicitation, dispute resolution, and termination conditions. For senior roles or roles involving access to sensitive information, the employment contract is the principal document both parties can rely on if a dispute reaches a tribunal or court. It should be signed on or before the first day of work.
Issued after the employee successfully completes their probation period, this letter confirms their transition to permanent status. The confirmation date is material: it is the reference point for tenure-based benefits that are conditional on confirmed status. Without a formal confirmation letter, the employee's standing is ambiguous, and the employer cannot later dispute claims that the probation was effectively concluded by conduct. Most companies set probation at three to six months.
These documents record the financial side of the employment relationship, from the regular payslip to the final settlement when an employee leaves. Each one feeds into the employee's tax filings, loan applications, or statutory benefit claims at some point.
A payslip is issued each month and is a legal requirement under the Payment of Wages Act for employees within its coverage. It must show gross salary, each deduction individually (PF, ESI, professional tax, income tax), and net pay. Employees use payslips for loan applications, rental agreements, and income tax filings. Errors here create downstream problems that are time-consuming to correct, particularly during TDS reconciliation and Form 16 issuance at year end.
An increment letter documents a salary revision. A promotion letter documents a change in designation, and often comes with a revised salary as well. Both should be issued in writing and retained in the employee's file. The revised figure in the letter must match what is reflected in subsequent payslips. Inconsistencies between the letter and the payslip are a recurring cause of background verification queries and, in some cases, tribunal claims.
The full and final settlement document is prepared when an employee leaves. It covers every outstanding financial obligation: salary for days worked in the last month, leave encashment, any unpaid bonus, pending reimbursements, and gratuity if the requisite years of service have been completed. Recoveries such as advances or notice pay shortfall are also recorded here. Both parties should sign and retain a copy. This is the financial quittance of the employment relationship.
Employees who have completed five years of continuous service are entitled to gratuity under the Payment of Gratuity Act, 1972. The nomination form (Form F under the Act) is collected at the time of joining. The claim form is filed at exit. The calculation uses the last drawn basic salary plus dearness allowance and the number of completed years of service. Under the New Labour Codes, fixed-term employees accrue proportional gratuity after one year of service.
These four documents close the employment relationship on paper. How promptly and accurately a company issues them is one of the more visible signals of how it treats its people at the point of departure. For a full walkthrough of the exit process, see the employee exit guide.
The resignation letter is the employee's formal notification of their intent to leave. It states the date of submission and the intended last working day, which together define the notice period being served. Employers should acknowledge receipt in writing and issue a formal acceptance letter confirming the last working day. Without both, the exit timeline is open to dispute if the notice period or final working date becomes contentious.
The relieving letter is issued on the employee's last working day. It confirms they have been formally relieved of duties and that all exit formalities are complete. It is not the same as the experience letter. Most companies and background verification agencies ask for both. An employee who does not receive a relieving letter on time often cannot complete onboarding at their new employer, which reflects poorly on the former company.
The experience letter certifies the duration of employment and the designation held. It is a factual document, not a character reference or appraisal. It should state the joining date, the last working date, and the role. Future employers and background verification agencies use it to confirm tenure. It should be accurate and issued without delay. Some employers combine the relieving and experience letters into a single document, though keeping them separate is the cleaner practice.
The exit interview form collects feedback from the departing employee on their reasons for leaving, their view of management, and any observations they want on record. The data is useful for identifying retention issues and recurring problems that line managers may not surface upward. The form is an administrative document, but the information it captures has practical value if it is actually reviewed rather than filed and forgotten.
These documents govern conduct, protect company information, and create the paper trail a company needs if a disciplinary decision is challenged. Their value is largely invisible until something goes wrong.
A show cause notice is issued when an employee is alleged to have violated a company policy or committed a disciplinable act. It asks the employee to explain their conduct in writing within a defined timeframe. This is the first step in a fair disciplinary process. Moving directly to termination without a show cause notice is one of the more common grounds on which a dismissed employee succeeds in a wrongful termination claim before a labour tribunal.
A warning letter is issued after the employee's explanation has been considered and the employer determines that the conduct warrants formal censure. It records the nature of the misconduct, the employer's finding, and the consequence of recurrence. Warning letters sit within a progressive discipline chain: verbal warning, written warning, and termination if the conduct continues. Keeping these letters in the employee's file is important if the matter escalates to a tribunal.
An NDA commits the employee to confidentiality regarding company information they access in the course of their work. It should define what constitutes confidential information, the duration of the obligation, and the consequences of breach. NDAs are typically signed at the time of joining. For roles with access to client data, financial records, or proprietary processes, an NDA is a standard precaution rather than an unusual imposition.
The employee handbook sets out workplace policies: leave rules, working hours, acceptable conduct, grievance procedures, and the company's expectations around ethics and compliance. Employees should sign an acknowledgment confirming they have received and read it. This acknowledgment is material if the employer later disciplines or terminates an employee for violating a policy the employee claims they were unaware of.
Leave application forms, attendance records, employment verification letters, and grievance forms are the operational layer of HR documentation. They do not typically feature in employment disputes, but they are the records an employer is most likely to need at short notice during an audit, a loan verification query, or a workplace complaint investigation. For a full breakdown of what goes into an employee record across the entire employment lifecycle, see the employee database guide.
The leave application form creates the paper trail for approved absences. It records the leave type, the dates, and the approving manager. Without it, leave balances and encashment calculations at exit rest on unverifiable estimates, which creates room for disputes. The attendance register is the parallel record for days actually worked, and is a legal requirement under the Payment of Wages Act.
The employment verification letter is issued on request, usually when an employee needs to confirm their employment status for a loan, a rental agreement, or a visa application. The grievance form gives employees a structured way to raise workplace complaints formally, and its existence helps the employer demonstrate that a redressal channel was available if the matter is later examined by a tribunal or the POSH committee.
