Can my target be deceased when using spelled candles?

Hi there! I’m going through it y’all but I will keep it as short as possible! Basically my parents passed when I was younger & have just recently learned that BOTH my fathers parents have also recently passed... with that being said, I am the last of our bloodline to carry on their last name...(my dad was an only child) & I feel entitled in a sense....My grandparents & I didn’t have much of a relationship due to how shitty my grandma was with my dad (she was judge mental AF), in turn kept me away. Although given our separation I without a doubt knew the love they had for me & my children & overall my father.... I recently found a will that was dated 2 weeks before my grandpa passed leaving everything to my dads cousin....cars, money, & paid off estate. it look sketchy as fuck...& knowing my grandparents, they were always fully prepared....this was had written, 2 weeks before his death. it is very hard for me to believe or except that everything including MY FATHERS baby memorabilia is being handed to someone else. There has to be another will of some sort & im having a difficult time getting answers. I have loyalty, obsession, DA, power, domination. Is there any way I can use those to possibly sway things my way? If so how?
