Hi Kayleb's Mom,
I've never dealt with a custody fight either but would like to offer you support.
Only thing I can think to ask is, is there something in your documentation that makes you think it will be interpreted as vindictive?
If it's full of asides and comments or sarcasm, I can see there might be a problem. But if it's objective, clear recounting of What Happened...I can't see how it could hurt.
If there are any problematic entries, could you photocopy them, and have an objective friend who's good with words look them over, and highlight any areas that seem overemotional, slanted, or sarcastic? Then you could retype or edit those pieces to be calmer, and serve your cause better.
Just a thought, for what it's worth.
I hope others here can help more.
Hopalong
