I was remitted from a debt by my father, but he bequeathed before passedaway that I should defray it. Am I obliged to fulfill his bequest?

Am I permitted to transfer all of my properties during my lifetime to my dutiful wife and sons and exclude my 3 daughters due to their rebellious attitude, bad manners, unveiling their Hijab and finally abandoning me? 

After my father had passed away, the estate was divided according to the provisions of the Jordanian Law although some of the heirs have unlawfully seized a large portion of it. Since things weren`t going alright between my brothers and my mother, she-with the consent of her big brother, my sisters, and her son in law who is a lawyer-decided to register the house in my name so that I keep it as a continuous charity after her death. After four years, things have changed a lot. My brothers forced her to take the house back. She claimed that she wanted to register it in the name of all the heirs. Should I give it back to her although it is likely that she gives it to my sisters? Or, should I register it in the name of the heirs and hers? This is because I don`t wish to incur Allah`s wrath or my mother`s for all I want is my lawful share.

My father passed away four months ago. Ten years earlier, he had given me the sum of 20.000JDs, and told me that he didn`t want it back and Allah is my witness that I am telling the truth. However, my brothers keep telling me that our father had no right to give that sum to me and that he should have treated all his children fairly when it comes to gift giving. They also say that he is being tortured for that. Should I give that sum back to my brothers? Is that money lawful or not? Is my father liable for anything before Almighty Allah?
