The value of co-broking is simple: your buyer gets access to stock you do not have, and your listing reaches buyers you have never met. The risk is just as simple: you hand a client to someone you cannot hold to their word. Finding a co-broker is easy. Finding one you can trust takes a few checks.

Where to look

Check them before you share a client

1. RERA registration

If the property is in a project registered under RERA, a broker who facilitates its sale needs an agent registration under section 9 of the Real Estate (Regulation and Development) Act, 2016, and section 9(5) requires the agent to quote that registration number in every sale they facilitate.[1] Section 34(d) requires each state Authority to keep a public database on its website of real estate agents who have applied and registered, including those whose registration was rejected or revoked.[1]

So ask for the registration number, then look it up yourself on your state RERA authority's website. Do not rely on a screenshot of a certificate. A registration that was rejected or revoked should show up in the Authority's own records.

2. Who they are

3. Their mandate

If a broker says they have the property, ask what authority they have from the owner. A broker who has only "seen" a property cannot deliver it, and a deal built on that is a deal that falls apart at the seller's door.

Red flags

Agree first, share second

The order matters. Share the requirement first and the client last:

  1. Share the requirement or the listing without the client's identity.
  2. Agree the total brokerage, the split and the payment trigger: see how to split commission between two brokers.
  3. Put it in writing: see what to put in a written co-broking agreement.
  4. Get your own client's consent to bring in another broker.
  5. Only then share the client's name and number.

The Brokers99 network is built around the same order: the split is agreed and locked before you share a client, network posts carry no client name, and client numbers stay hidden until you reveal one with your PIN.
