A trust is something done through an attorney, correct? Yes, at the least sounds like I will need to change who the beneficiary is.
I also feel like I need to change my (and hopefully his) will, regarding guardianship. Right now, ex's sister is listed. I had reservations about this from the start, but she won out because she is nearby and it would be the least disruption (same school system, etc). But frankly, she does not treat my children well. Even Ex agrees she does not act like an aunt to them. Ex agreed with me in the will to have the financial executor be different from her, because of these issues (that she might use money paying off her house, or on her kid, than for raising our children).
After everything that has happened, even more so I do not want the chance she would be guardian for my kids. She has always been very chilly to me, but in the months before ex left, she unexpectedly "befriended" me. This wasn't characteristic of her, and she said it was because she had gone through a separation and wanted to be there for me. Instead she actively lied and covered for ex. The only thing I can think, she really detests me. With my kids not far behind.
There are at least 5 people I can think off the top of my head I would rather have raise my kids.
