payment to builder from blood relatives account

I have purchased a new under construction property in Mumbai on self funding basis. property is registered on my name only. while making payment 90% payment is made by me from my account but around 10% money paid by my younger brother to directly builder wrongly instead of sending to my account bcoz of lack of knowledge in us. And all the money which was paid by brother to builder that I have returned to brother account with heavy interest and also have taken NOC. Can my brother claim share in future in said property as some money he had directly paid to builder bt property register just my name only.
