You have mistaken statutory residency with domicile.  Those are two totally different legal concepts.

Like I said in my last response, what you told us about your client and her son is that they are statutory residents of CA but that does not indicate in any sense their domicile is also CA.

Yes, you also gave us the spouse's date of relocation.  Again, that is no indication of his domicile.

Suggest you look into these again and come back to us with what you find out.
