Possession date vs RERA completion date vs occupation certificate: what buyers should know

By the Shortlist team · Published 24 Oct 2026 · 5 min read

A project’s “possession date” is what the developer markets and writes into the sale agreement; the RERA completion date is the deadline the developer declared when registering the project; and the occupation certificate is the local authority’s permission to live in it. Buyers need all three — and they are often different dates.

Three dates, three sources

  • Possession date (developer). Shown on the website and brochure, and — the one that counts — in the agreement for sale.
  • RERA completion date (registration). When registering, the developer declares the time period within which it will complete the project (RERA Act, Section 4). State RERA websites show it, often with a “registration valid up to” date that can be extended.
  • Occupation certificate (local authority). Confirms the building can be occupied. The developer is responsible for obtaining completion and occupancy certificates (Section 11).

Why they differ

Developers usually market a date earlier than the RERA deadline, keeping a buffer. Registration dates can also be extended, and large projects are registered in phases with different dates. In our own catalogue, one project’s developer page gave a 2028 completion while its registration ran to the end of 2031.

What to tell a buyer

  1. Quote the date from the developer, labelled as the developer’s promise.
  2. Give the RERA date too, as the outer limit, with the registration number and the date you checked it.
  3. Point them to the agreement for sale: under Section 18, if the developer fails to give possession as agreed, the buyer can ask for a refund with interest, or interest for each month of delay if they stay in the project.
  4. For ready-to-move homes, ask to see the occupation certificate before booking.

Common mistakes

  • Calling a RERA date the “possession date” — it’s a regulatory deadline, not a promise of handover.
  • Leaving the date blank when the developer hasn’t published one. Write “not published” and ask.
  • Assuming every tower in a project shares one date. Check which phase the unit belongs to.

General information, not legal advice. State RERA rules and individual sale agreements apply.
