Dad Convinced Grandma to Cut My Inheritance: Is That Fair?

Imagine finding out that the money you were set to inherit — enough to buy a home and start a family — quietly disappeared because your own father talked your grandmother into cutting you out.

If you're in a similar situation, talking to an estate attorney about whether undue influence could apply is a reasonable first step, even if the bar to prove it is high.
