So you find an account where she was hiding money, rather than keeping your mouth shut and letting your attorney catch her in a lie in front of a judge, you decide to call her and argue with her about it. You need to STFU and let your attorney do his job.
This.
I mean really. STFU. Do not call her, do not text her. If you have kids, have your parents or hers be the intermediary for visitation.
First advice when found in a hole, quit digging.
Take her threat seriously, she has already "lied to the court" if she submitted financial paperwork and hid assets. Her making claims to the FAA is just around the corner. Make sure your claim above is documented, and have your attorney handle it from here.
Would you let your attorney fly your plane? No.
Then quit trying to be a lawyer and let him do his job and keep your mouth shut.
I have a feeling that none of this advice will be heeded. I got divorced, my lawyer sat me down and told me to shut up. He wasn't even nice about it (he was a friend). I didn't listen, ended up costing me a lot of money and time. For about a decade after the divorce and custody battle were over, he would send me postcards from his condo in the BVI's every winter.
All that was written on the postcard was "THANKS!!!"
I was in court one day fighting over something little, can't remember exactly what it was about. I had him, the child psychologist and a paralegal there. We were nearly through the custody battle, and I wanted to fight over something little that day.
He grabbed me by my shirt collar and drug me to the hallway and dog cussed me. He said this is costing you $1,200 an hour and you are fighting over loose change. Get your act together.
