From the contents of your post it can be understood that you had transferred the property to your son by a registered gift deed, but the problem in this is that you do not have title or interest in the property, hence the transfer made by the donor without any title to the property is legally invalid and null and void.
Besides, when the property was on your mother's name, there was no necessity for your sister and brother to involve in this and execute a partition deed in your favor.
The transfer of revenue records to your name based on the said non maintainable partition deed is also invalid and illegal.
Thus as per law,. the property still lies on your deceased mother's name alone.
In this situation, the next option before you is to execute a cancellation deed cancelling the gift deed executed in favor of your son, if it is within three years period and ask your siblings to execute a registered lease deed in your favor relinquishing their rights in the proeprty.
Once you become an absolute owner of the property you can transfer the same properly as per law to your son or anyone of your choice.
