If your neighbor sells their property or floors, the new owner is not legally bound by a simple NOC issued by the previous owner.

2)  Draft a formal "Mutual Settlement and Reciprocal NOC Agreement".

3)  The agreement must explicitly state that it is binding not only on the current owners but also on their heirs, executors, administrators, and future purchasers/assignees.

4)  For an agreement affecting immovable property rights to be enforceable against third parties (like new buyers), it should be registered at the Sub-Registrar's office. An unregistered NOC may be considered "futile" for future enforcement.

Your concern is completely valid. A simple one-line NOC exchanged casually can create complications later — especially if your neighbour sells the property, transfers floors to third parties, or if a future owner refuses to honour the understanding.

A plain NOC is usually personal between two neighbours, does not automatically bind future buyers, can be misused if not properly worded, and does not protect your future construction rights by default. If your neighbour sells the property after obtaining your NOC, the new owner can later deny giving you any reciprocal right unless it is properly recorded in a binding document. Therefore, you should not give a simple NOC letter.

The safest and most legally accepted method in Gurugram and across Haryana is to execute a Mutual Reciprocal NOC-cum-Settlement Agreement instead of merely exchanging NOC letters. This should be prepared on appropriate stamp paper, signed by both property owners, and preferably notarised or registered for stronger legal protection. Such an agreement will grant your neighbour NOC now for stilt plus four floors while securing your equal right to construct the same in the future, and it will bind future purchasers as well.

The agreement must clearly mention that you will have full and equal rights to construct stilt plus four floors whenever you choose without requiring further consent. It should specify that the NOC and reciprocal rights will run with the property and remain binding on successors, purchasers, transferees, and assigns. It should also clarify that by granting NOC now, you are not waiving your own construction rights, and that neither party nor future owners shall object to construction carried out as per law. Additionally, it must include a clause stating that if the neighbour sells the property or any floors, the buyer will be bound by this agreement.

If you give only a simple NOC letter, there is a significant risk. However, if you execute a properly drafted mutual agreement with binding clauses, your rights remain protected even if the property changes hands. Courts generally uphold such reciprocal development agreements.

Registration of the agreement is not legally mandatory but is highly advisable where property values are high, builder floors may be sold, or long-term protection is desired. A registered agreement offers the strongest legal safeguard, while notarisation is usually sufficient but slightly less robust.

In summary, your rights are not automatically protected by issuing a simple NOC. Exchanging plain NOCs is risky. The best solution is a mutual reciprocal NOC agreement that binds future owners and is preferably notarised or registered.

If you require, I can assist in drafting a proper Mutual Reciprocal NOC-cum-Settlement Agreement with all necessary protective clauses in line with Gurugram/Haryana practice.

The NOCs for additional floors often create disputes later, especially when properties change hands.

You can execute a Mutual / Reciprocal Development Consent Agreement. 

Instead of just exchanging NOCs, both parties should sign a registered agreement.

The agreement may contain mutual rights clause. You may mention  that both the properties have equal right to construct Stilt + 4 floors as per municipal rules. You should ensure that your  consent is based on understanding that your right remains intact.

You may include that the consent shall be binding on present owners and their successors, purchasers, tenants, builders, developers etc.  This will prevent the  future buyer from denying your right.

You can engage the services of an advocate either from this forum or outside for the purpose. 

The noc will not stand for a new owner if same is not stated in the parent document. You need to get it registered and also take indemnity bond from them

Dear client

NOC usually provides municipal approval between you and your neighbour in Gurugram; however, it doesn't automatically transfer ownership rights to the property you're being granted access to, & could result in disputes later if it's not written properly.

First of all, an NOC that you provide to your neighbour will likely still be in effect even if such neighbour sells their home unless there's something in your NOC to the effect that it is personal & not transferable to a new owner; therefore, you should state very clearly in writing that the NOC is both conditional & reciprocal.

In order to protect yourself:

Prepare a written Reciprocal NOC Agreement, which is signed by both parties before a stamp duty pays on each party for the execution of the agreement.

Clearly state in writing that both parties have equal rights to build their respective stilt + 4 floors as per rules. 

State that if either party sells their property, then both parties will keep their construction rights; however, this will not apply to land owned under the jurisdiction of any other company/firm & they will be bound by their deed of conveyance.

Clearly outline that neither party will contest any future construction permitted under municipal law.

For greater protection obtain 3 copies of the agreement, and get at least one copy registered with the Sub-Registrar's office.

If your NOC was executed by your neighbour prior to your purchase of your property, it only binds the property itself, not the previous owner; however, you should read the NOC carefully to see what it says.

Your most important task is to ensure that the Reciprocal NOC Agreement clearly outlines the terms of your future right to construct , before you actually issue an NOC to your neighbour. You will not be able to use an NOC that is nothing more than a letter with no signature. Statements should be made in accordance with the governing statutory law for the laws of Haryana. It is advisable to employ a qualified attorney for assistance in creating these documents.
