My dad died before I could pay him back $20,000 that he lent me.
My dad had a Will that left 50/50 to my sister and myself. $1,000,000 each.
My sister changed my dad's Will when he had dementia and he had no idea what he was doing.
My sister ended up with all the money being $2,000,000 in total.
Do I have a moral obligation to give me sister half of the $20,000 that my dad lent to me that I never repaid to my dad?
