Dad doesn't need a lawyer to file contempt on Mom. Dad can - if he's willing to learn the local rules of procedure etc., - file himself.
I honestly cannot see this going in Grandmother's favor. I'm sorry it's not more positive news.
Because unless Mom is found to be unfit, she has a constitutionally protected right to parent her children. Third party custody suits are very, very difficult to win and without a decent attorney the chances are even slimmer.
To help you understand a little bit about what may have happened without mediation:
Judge: Grandma, you are here because you are requesting custody of Child, correct?
Grandma: Yes.
Judge: Mom, do you agree to Grandma having custody?
Mom: Certainly not.
Judge: Ok then. You'll be required to go to mediation before the matter will be heard in my courtroom again.
Next case please.
Grandma wouldn't even get a chance to speak.
See where I'm going?
Just another thought - has your son requested a GAL (guardian ad litem) be appointed?
