When drafting a deputation letter for a domestic client, it is crucial to include specific clauses to protect the interests of both parties involved. Between the two parties, key clauses should cover details such as the purpose of deputation, duration, compensation, roles and responsibilities, confidentiality, termination terms, and dispute resolution mechanisms. For the new joiner and the parent company, clauses should focus on compliance with company policies, reporting structure, performance expectations, confidentiality agreements, non-compete clauses, and any specific terms related to the deputation. It is advisable to seek legal counsel to ensure all clauses are legally sound and protect the rights of both parties. Prioritize clear communication and mutual understanding to facilitate a smooth deputation process.
