To make a field required only in some states, leave it as not required in the Model, and in the form view set the conditions on which the field will be required:

<field
    name="fiscal_position"
    attrs="{'required':[('state','in',['pending','open'])]}"
    />

If you write required=True in .py file then ORM will add not null constrain to that field.

There are multiple ways to do your code.

Make required=True in .py file and set default value for that field.
Make required=False and set required=True in view.xml.
Make required=False and set required=True in view.xml for some state of object.

This may help to solve your problem.
