A little boy sang it. It was about his parents getting a divorce... says. Daddy don't sign the papers..

Think it could be called 'Daddy Don't You Sign The Papers' by Six Shooter. I couldn't find it on YouTube, but you can listen to a clip of it on Amazon.com, just call up six shooter and use the mp3 option then at least you'll know if it's what you're looking for :)

Here are a few more lyrics from it

Don't know what to do I'm so afraid
Daddy don't you sign the papers
Daddy put down that pen
Why won't you and Mamma be in love again.
