Form validation for hidden fields

Hi,

I have a form with multiple child panels like -

MainPanel

Name, MaritalStatus and Province

ChildPanel_one (Only visible if MaritalStatus is true in MainPanel)

Spouse Name, Spouse DOB, Spouse Salary 

I have set a validation expression for ChildPanel fields. 

My problem is, even if the ChildPanel is not visible- AEM form validates the  childPanel fields and gives me the validation error.

Right now to avoid this, for every child panel field I have to set validationDisable=true in initialization expression and make it false when MartialStatus is true (Value commit script).  

This is becoming a pain since I have so many fields and so many child panels (Child panels inside child panels as well). 

Any help ??
