Both parents don't need to be physically present; one legal parent can be there in person
http://travel.state.gov/passport/get/minors/minors_834.htmlThe minor and both parents (or guardians) must appear in person to submit Form DS-11 at an acceptance facility or a passport agency.
My sister just went through this last week....
I'm guessing since the OP is accusing the ex of forging signatures, none of this applies.and submit either a consent form from the other parent, or offer proof of why the other parent cannot consent (jail, unfindable, death, living outside of the US).
