How do I change the Primary Point of Contact between Parent 1 and Parent 2?
There is a button on the User Parent tab to switch the Primary Point of Contact.

This is for when a parent detail is not being changed. e.g. when a parent is being made the Primary User for the purpose of completing documentation within EnrolHQ.
You can also switch Parent 1 and Parent 2 ( always know that the parent with head and shoulders it the Primary User Parent)
How do I change the user parent/switch Parent 1 and Parent 2?
There is a button on the User Parent tab to switch.

You would use this button if you wanted a particular parent as Parent 1, ie Father as Parent 1 and Mother as Parent 2
Please note, if you switch, Non-User parent will be able to see all information the User Parent has completed. This may be important if this is a split family with court orders in place.
