My ex-wife just called and said that she misplaced her clerk's transcript, and asked to borrow mine so that she can file her appeal brief against me! I said sure. I am a chump.
In reality, it wouldn't make much difference for me to refuse. She would just ask for an extension until she found it, or buy another copy, or just wing it. The legal issue is fairly narrow and the court is probably going to do whatever it wants to do no matter what she says.
