How should a church build a medical release form for a child, parents, and emergency contact in Planning Center People?

Answer

Make the submitting parent the top-level Profile fields and the child a Household Members field entry (not the reverse); route the second parent as a second household adult, emergency contact and medical/insurance details as Basic fields or custom fields on the child, and use a required checkbox + typed name as the signature since Planning Center Forms has no native e-signature field.
