I wouldnt be so sure a female judge is prone to be more sympathetic to your W. Originally we had a male judge (very nice, very fair) and it was my H's attny that actually requested a judge change to another judge who happened to be female (again, very nice and fair).
Considering my H had an affair and the illness I have my H's attny took a HUGE risk in requesting a judge change as there was a good chance the new judge would be female.
Judge's dont rule based on gender. There job is to examine facts and what is in the best interest of the child(ren). And your legal counsel will be able to present that in the best way for you.
Both judges we had (the male and female) didnt seem to handle things any different based on their gender. All I can say is they were both nice, fair, calm and from what I saw there was no bias based on gender.
The man judge was older and the female judge was younger. I dont think gender or age demographic plays a big a role as one would think. Or I should say in *my* experience it did not.
In our family court its about 50/50 with male to female judges.
