Rent agreements in India are often structured to be 11 months long primarily to avoid the registration process required for agreements that are 12 months or longer. Here’s why this practice is common:
1. Stamp Duty and Registration Costs: If the possession of the rented property is less than a year, registration is not required. A lease agreement with less than a year duration is not needed to be registered under section 17 of the Registration Act, 1908.
2. Convenience: By keeping the agreement to 11 months, landlords and tenants can avoid the hassle and expense of registration. This is particularly advantageous when either party is unsure about the long-term commitment or wants flexibility.
3.Legal Considerations: Rental agreements of 12 months or more must be registered to be legally valid and enforceable in case of disputes. Shorter agreements (like those for 11 months) are still legally binding but don’t require registration, making them more convenient for temporary arrangements.
4. Renewal Flexibility: After the initial 11-month period, the agreement can be renewed with mutual consent of both parties. This flexibility allows adjustments to rental terms, conditions, or termination clauses based on the experience during the initial period.
5. Local Practice: The 11-month duration has become a customary practice in many parts of India due to the above reasons. It's a balance between legal compliance, convenience, and flexibility for both landlords and tenants.

It’s important to note that while an 11-month agreement does not require registration, it still needs to be properly drafted to clearly outline terms such as rent amount, duration, responsibilities of both parties, and conditions for renewal or termination.
