I’m sorry this is happening. I’ll share a mistake my sister made when she got divorced 11 years ago. Their son was 10 at the time. During the divorce process her soon to be ex made what seemed to her sincere promises about sharing the financial aspect as their son grew into teenage years. She took him at his word & didn’t address things in writing in the divorce decree. When the kid reached high school the ex reneged on all those financial promises. It was a mess. She admitted later she wished she had been insistent on putting everything into the decree. So, be careful, get a really good attorney. Hoping for brighter days to come your way.
