Issues building Business Rules for creating vs editing records.

Summary:

We are struggling with creating validation rules when creating vs editing records. We creating/editing a new contact we want a warning to appear if someone is a spouse or child and no national identifier is added.

The below code works for Creating New

This code does not work when editing a contact. The National ID field is only populated when editing the national identifies region. The Relationship (field values) are only populated when editing the relationship region. I'm going to have to play with comparing initial values with field values, it is going to get messing.

Has anyone had any luck defining rules based on Creating vs Editing any easier?
