What are conditions for grant of Petition for probate?

Under  a  petition for  grant  of  probate  to succeed there  must be a will.  See  section  24(1)  of  the Probate and  Administration  Act, Cap,  352  provides  that; 

24(1) “Probate  may be  granted  only to an executor  appointed by the will”  and Rule 33  of the Probate Rules requires, inter  alia that;                                        

a).  The last  will  of the deceased and  all  codicils thereto shall accompany the petition for  grant  of probate.  Discussing the two provisions the Court  of Appeal  of Tanzania in Hansund  Ghikas vs. Ludiuma G.  Ghikas [1992] TLR  288  said at  pg  259  thus;   

“  the reading  of both provisions  makes it  abundantly clear  that the petition for, and grant  of probate presuppose the  existence  of a will" 

Note:  The term  codicils means instruction that  is added  later  to a will, usually to change part  of it.
