Legal Question in Wills and Trusts in Nevada

My guess is that the "gambler" and his ex are doing more for your aunt than you or your sister. If that is the case, your aunt may rationally be happy to have them in her life and may rationally include them in her estate plans. If she creates new estate plans that include the "gambler" and his ex, you might challenge the documents after she dies as being due to "undue influence" but such a challenge would be tough unless you could prove she was not mentally competent. If you could prove she is not now mentally competent you could seek to have a court appoint a guardian for her, but she would likely resist. Either of these two courses of legal action would involve your paying upfront legal fees with no assurance of success.

Assuming your aunt is mentally competent, you could speak frankly to her about whether she intends to include gambler and his ex in her estate plans or whether she is giving him present gifts of money. She might welcome a frank discussion if your position is other than that you and your sister are entitled to 100% of the money and she is a 75 year old sucker if she thinks otherwise. Or she might think you are just waiting for her to die so you can collect. Or she might tell you that she has no plans to change the present will just to get you off her back. You should know better than anyone else whether you can have such a frank discussion with your aunt and whether it will likely be productive.

It's her money, not yours, and it is her right to do with it as she pleases as long as she is mentally competent. See my web page http://probatenevada.net/WillContests.aspx at www.probatenevada.net
