My question involves estate planning in the state of: Wisconsin
About 12 years ago when my grandmother was of sound mind, I took her to get her will created. At that time she made it very clear that 50% would go to my mother and 50% would go to my uncle (her only 2 children). My grandfather has been deceased for a long time. My grandmother also put in the will that if my mother would pass away before her, that my mom's 50% would get divided up among her 4 children (me and my siblings). My mother passed away 10 years ago (so she did pass away before my grandmother).
My grandmother is now in a nursing home with alzheimers/dementia and isn't doing too well. My uncle made it clear to my siblings and I recently that "the will has been changed" and won't give us any more information. My siblings and I think that my uncle had the will changed and had my grandmother sign it (which she wouldn't know what she was signing because of alzheimers).
Is there any way that we can look at the will before grandmother passes away - is it public record? Do my siblings and I have a case against my uncle because he changed the will after my grandmother got alzheimers?
Please advise. Thanks.
