Dear sir/ma'am,
yes, you can send money to your father that he can buy the property in his name. he can later make a gift deed to you or make a will and transfer the ownership of the land to you by the above declarations. it is advisable to make all the agreements registered and not on the stamp or notary to save few rupees. getting the documents registered will make the agreement legally valid fully and can be used as a form of evidence in the future for whichever reason.
