Colorado divorce - inheritance question
Hello all. Looking for advice. Let me start by stating the facts.
My father passed away in 2016. My grandma pulled my aunt and I aside and explained that since my dad was gone, she wanted their assets to be split between my aunt and me when they passed (verbal only).
Married in 2017
My grandma passed away in 2019
My grandpa passed away in December 2022
My grandparents did not change their will so it still stated that assets would be split 50/50 between my aunt and my dad
My grandpa's investment accounts and retirement accounts listed my aunt and dad as beneficiaries.
My aunt was the executor of my grandpa's will
The retirement accounts and investment accounts all moves to my aunt's name at the time of my grandpa's death
My aunt and I worked with the financial planner responsible for the accounts to split them 50/50 and put half under my name in February 2023
The accounts have remained in my name only
They have certainly grown since then and I understand that the amount of growth is considered marital assets and I agree it is absolutely fair to split the growth
Now that I am getting divorced, my wife is questioning the validity of my inheritance and demanding half of the full amount if I can't prove that it is an inheritance. I have asked my aunt for a copy of the will which she will send me on the 12th. I have asked the financial planner for any communications and statements that he might have which he will send me tomorrow. I am also speaking with my divorce attorney for his opinion/recommendation on the 8th.
What is the best way to prove it to her and her lawyer and protect my assets?
Thank you for reading.
