According to the UN convention on the law of the sea article 92.[0] Ships in international waters are subject to the exclusive jurisdiction of the state under whose flag they are sailing. It is basically the same situation in regards with the legal subjectivity of an object since usually in international waters local laws do not apply.

There is also the case of the ISS and the intergovermental agreement behind it where in article 5. it is clearly stated that: "each partner shall retain jurisdiction and control over the elements it registers and over personnel in or on the Space Station who are its nationals"

And finally the most iportant is the outer space treaty, signed by most of the states in the world, article 8.:

"State Party to the Treaty on whose registry an object launched into outer space is carried shall retain jurisdiction and control over such object, and over any personnel thereof, while in outer space or on a celestial body"[2]

What is your government if I may ask?
