Generally, a minimum duration of 11 months is advised as per the provisions of the Indian Registration Act, 1908. This is because rental agreements for a duration of less than 12 months do not require compulsory registration.

Typically, rental agreements include clauses specifying the conditions under which either party can terminate the agreement before its expiry. These conditions may include providing a notice period to the other party, payment of penalty or compensation for early termination, or any other mutually agreed-upon terms.

As per Indian law, it is not compulsory to register a rental agreement if the duration of the agreement is less than 12 months. 

Its important to clearly mention the rent amount, due date, acceptable payment methods, and consequences of late payments. Don’t forget to  allocate responsibilities for property maintenance and repairs, including regular upkeep and any specific obligations of the landlord and the tenant. Lastly, define who will bear the costs of utilities (water, electricity, gas, etc.) and any other services associated with the property.
