15 June 2025 Dear Sir
Builder has provisionally allotted an under construction shop to me and I have paid less than 10% amount of total consideration money.
As per builder's terms and Conditions allotte can transfer in full or in part, the provisionally allotted shop to his close relative without any charges.

Accordingly, I have applied to transfer 50% of share of this allotted shop in favour of my son and builder has transferred the same in favour of my son. And now we are joint allottes of this shop

Sir pls guide, if any further documentation required or not between me and my son under any law? If required, which one.

Sir further after that some payment made to builder by me (i.e. my share and my son share) and builder given joint receipt of the same.

Pls guide, if any further documentation required or not between me and my son under any law? If required, which one.
Regards
K M Goyal.
