That is EXACTLY what I answered. The method I outlined for you is the same whether you are trying to put a lien on someone else's property (and I knew that is not the case) or someone else is trying to put a lien on your property.
The State of California can't just apply a lien from their state to property in another state since they are a separate entity. So, what they have to do is get their lien made into a Georgia lien. Some states have specific "interstate compacts" that provide a method for this but I didn't see one of those that exist between Georgia and California regarding liens. Therefore, the method I gave you before is how they would go about it. There is a different interstate compact called the Uniform Enforcement of Foreign Judgments Act (UEFJA) that provides the basis for doing this.
California takes their lien or judgment, either one, and takes it through a Georgia Court and domesticates it. That is covered by O.C.G.A. § 9-12-131 and the other statutes after that.
By this becoming a Georgia lien or judgment at that point it can then be enforced against all of the Georgia property including real estate, wages, etc.
So, that is how California can put a lien against your property/income in Georgia.
Please ask any follow ups in this thread. I hope I clarified the way that this California can move their lien to Georgia.
