What is an Allotment Letter? Format, Importance, and Provisional Allotment Explained

Buying a property is one of the biggest financial decisions you will ever make, and the allotment letter will be one of the first important documents you will get from a builder or developer in this journey.

Whether one is a homebuyer, a developer, or a real estate agent, the allotment letter and its format are crucial to understand, as is how it differs from a provisional allotment letter, especially in a RERA-regulated environment.

It provides the first legal evidence of owning a property and contains necessary information like:

  • Terms and conditions of the allotment

Why Is an Allotment Letter Important?

  • Acts as a legal record of ownership intent

Under RERA, the issuance of proper documentation is imperative, wherein the allotment letter should correctly reflect the property details promised to the buyer.
