I LIVE IN HOUSE WHICH WAS BUILD BY MY GREAT GRANDFATHER. MY GRANDFATHER PASSED AWAY AND MY GRANDMOTHER IS STILL ALIVE. THEY HAD TWO SONS. ELDER ONE IS MY FATHER AND YOUNGER ONE IS MY UNCLE. I AM MY FATHER'S ONLY DAUGHTER. THE HOUSE HAD 3 EQUAL SHARES GIVING(MY GRANDMOTHER, MY FATHER AND MY UNCLE). MY GRANDMOTHER GAVE ME HER SHARE OF THE HOUSE ON PAPER. MY UNCLE MARRIED A LADY WHO WAS A WIDOW AT THE TIME OF MARRIAGE AND HAD AN ADULT DAUGHTER FROM HER PREVIOUS MARRIAGE. NOW SHE IS MARRIED AND HAVE A SON OF HER OWN. MY UNCLE AND AUNT HAVE BEEN LIVING SEPARATE FOR LAST FIVE YEARS. MY UNCLE LIVES IN THE ANCESTRAL HOUSE WITH US.
NOW, MY QUESTIONS ARE, WHETHER THIS DAUGHTER OF MY AUNT'S PREVIOUS MARRIAGE WILL INHERIT MY UNCLE'S SHARE OF THE HOUSE AFTER MY UNCLE PASS AWAY FIRST BEFORE MY AUNT?
AND IF MY AUNT PASSES AWAY BEFORE MY UNCLE THEN WHAT WILL HAPPEN TO MY UNCLE'S SHARE OF THE HOUSE?
IF MY UNCLE LIKES TO MAKE A DEED OR A WILL NOW TO GIVE HIS SHARE OF THE HOUSE TO ME, THEN WILL THAT REQUIRE MY AUNT'S PERMISSION/SIGNATURE/ PRESENCE ON PAPER?
