I've decided not to share any of our dad's money with my sister when he passes.
Doesn't you dad's will specify how his assets will be divided?
I think we each get to keep what we work hard for.
You shouldn't turn your back on your sister like that. She's gonna be really upset with you when she finds out.
What's the point of working hard if you don't get the things you want. She can just take over the farm when I'm gone. I do all the work there anyways.
If your dad didn't write this in his will, he's set the stage for a real donnybrook between you and your sister. Expect to hear from your sister's lawyers and be prepared to spend a lot of the money on legal fees.
