If you are cross-examined by the other L, be aware that it's his/her job to suggest you are not Dad of the Year, and your job is to not emotionally engage with those falsehoods.
Ive only been on the stand one time and it was for the final order, I had a horrible lawyer and was not prepped at all for the stand. I had never in my life been on the stand and I was a nervous wreck but did very well when my exs lawyer came after me with a bunch of lies by my ex. It was easy because all I did was tell the truth and be honest, in fact he quit asking me questions because it was starting to dig the hole deeper for my ex by punching holes in her claims.
In these types of situations im solid as a rock, I have anxiety issues so im very nervous but once I focus on telling my side I do fine. her lawyer tried to shake me by interrupting me and taking small jabs at my character but that didn't really bother me. It ended on a great note on the stand when I turned the question to him " wouldn't you do the same for your kids as a father? " He agreed and said no further questions
