Consultant Appointment Letter on Retainership - Updated India Format

A modern appointment-letter specimen for engaging an independent professional, adviser, specialist, retired professional or consultant on a retainership, fixed-term or assignment basis.

Current drafting position: the legal character of the relationship depends on the actual working arrangement, not merely on the words "consultant" or "retainer". India's four Labour Codes came into force on 21 November 2025. Where the engagement functions in substance as employment, mandatory labour-law rights and obligations may apply despite contrary labels.

Current legal framework

Indian Contract Act, 1872Consultancy and retainership arrangements should satisfy the ordinary requirements of a lawful contract, including competent parties, free consent, lawful consideration and lawful object.

Professional statusThe letter should identify scope, autonomy, reporting interface, availability and fee structure without disguising an employment relationship where one exists in substance.

Labour Codes from 21 November 2025The Code on Wages, Industrial Relations Code, Code on Social Security and Occupational Safety, Health and Working Conditions Code are in force. Their application depends on the statutory definitions and actual facts.

Confidentiality and dataIf the consultant handles digital personal data, the engagement should allocate data-security and confidentiality responsibilities consistently with the DPDP Act, 2023 and the phased DPDP Rules, 2025.

GST and invoicingWhere GST registration and taxability apply, professional fees should be invoiced in accordance with the CGST Act and applicable invoice rules.

Regulated professionsAdvocates, chartered accountants, doctors, architects and other regulated professionals may be subject to separate statutory or professional-conduct restrictions.

For advocates: do not use a generic employee-style clause such as unrestricted transfer, compulsory exclusivity, or complete managerial control without checking the Advocates Act and Bar Council rules. The engagement must preserve professional independence and comply with applicable professional conduct requirements.

Important checks before issuing the letter

Use consultant/retainer terminology only where the actual relationship is genuinely independent.
Avoid employee-style control, transfer, exclusivity and benefits clauses unless intended and legally appropriate.
Check applicable Labour Codes where the individual works under substantial control or resembles an employee/worker.
For advocates and other regulated professionals, tailor the appointment to applicable professional-conduct rules.
State whether the fee is plus GST and subject to TDS/other statutory withholding.
Define deliverables, ownership of work product, confidentiality and data-security obligations.
Use a post-termination restraint only to the extent valid under Indian law; Section 27 of the Indian Contract Act restricts agreements in restraint of trade.
