Foreign companies doing, or planning on doing, business in California should be aware that a recent decision from the California Court of Appeal for the Fourth District held that under certain circumstances a foreign corporation can be validly served in California by serving such corporation’s California-based subsidiary despite the requirements of the Convention on Service Abroad of Judicial and Extrajudicial Documents in Civil and Commercial Matters (the “Hague Service Convention”). Such decision requires foreign companies to be alert to the receipt of service documentation by their California-based subsidiaries.
