This is in no way an official will and I know it would not be valid. But I do want to make clear my intentions if I die before any of my my children are 18. I don't have a lot but I do have a little. I am worried that if something happens to me, while my kids would be my beneficiaries, their fathers would ultimately have control over their portions of my estate.
For that reason I will be creating a trust in my will that holds their portions of my estate until they are 18 or 20. I haven't decided the age. I want the money to go to them and not their fathers. I expect my children will receive nothing from their fathers if they pass because they are both married and would leave it all to their wives and ultimately their wives would leave everything to their own children, and not my and his kids. So this is my way of taking care of my kids' futures.
The Trustee would probably be my sister because I know she won't be bullied to release the money early for any reason to their fathers.
