A buyer is at liberty to nominate any person in his place for registration of sale deed. Draft an affidavit on stamp paper of 100 directing the seller to register property in name of your son. If you are abroad, you can get the affidavit attested by Consular Office which  they will ready will do and send it the you son, marking a copy to seller with a covering letter. That is sufficient for the seller to register the property in the name of your son. If you are in India you can get the affidavit notarized.

It is very much possible. What you need to do is to fully transfer the allotment rights in favor of your son.

Contact your builder for the formalities in involved in the transfer of allotment. A bit of paperwork will be needed; but this can be very much done. 

Approach builder in this regard 

builder would insist on affidavit from you and also indemnity bond to indemnify him in case any claims are made 

1. Art the time o registration you can put yur son;s name as the buyer and your's as the c informing party .

2. This would save lakhs of your money.

 The seller is not authorized to transfer his rights or interest in a property to a buyer and only the builder can do so.

 In Direct Transfer of Under Construction Property, there is no agreement between buyer and the builder.

The entire transaction is based on NOC issued by the builder.

Here the seller is the father and the buyer is the son.

the best way to transfer the under construction property is by entering into a tripartite agreement or an assignment deed.  

You can inform the builder about it and can enter into a tripartite agreement with the builder involving your son as the third party and new buyer to buy the proposed party.

In this agreement the builder would register the property to your son's name on the basis of the agreed terms and conditions.

- As per law, without Registration a buyer has no legal right over the property even he has cleared all the dues with the builder, and further cannot sell it to anyone under the Transfer of Property Rights Act.

- Since, you have entered into an agreement with the builder in your name , then you should approach the builder and request him to make changes in the Builder-Buyer Agreement and transfer the ownership rights in the name of your son. 

- As per rule the builder after collecting processing charges , can register the property in your son name. This processing fee is charged to change the Builder-Buyer Agreement.

-   Builders charge fees if buyer wants to sell to someone else.
but in your case, you only want to change to your son.
So it is very much possible.
Contact your builder for the formalities in involved in the transfer of allotment.

-   If builder asks lot of money which they will try then you can add son as joint buyer.
After registration, you can do Relinquish Deed of your share for your son.
Fees for Relinquish Deed is very less.

-   If builder asks lot of money to add son as joint buyer.
Then also dont pay to builder.
After registration, you can do Gift Deed to your son.
Fees for Gift Deed is very less.

No further additional documents would be required

1. Since the Registration of the property has not yet been done, the said change can be made by the builder.

2. Talk to the builder in this regard and he will ask for a letter from you to make the said change in the allotment letter and also the agreement. In worst case, the builder might ask for fees for substituting the allottees name (which they do in case of pre registration sale).

OCI Card no. is required for the registration of properties in favour of  an OCI.

- OCI card holder can buy residential or commercial property in India.

- If he is in India for registration then no problem.
But if he is not in India then he have to give POA to you/someone.

1. Just give a simple letter in writing to builder asking him to execute sale deed in favour of your son.

2. There is always a clause in the agreement to sale that seller will execute the sale deed in favour of either the buyer or anyone else at the desire of buyer.
