Act Governing the Choice of Law in Civil Matters Involving Foreign Elements Article 22

Where a juridical act results in an obligation on a security made payable to order or to bearer, and is not governed by Article 21, the formation and effect of the act are governed by the law of the place where the act was performed; where the place of the act is unclear, by the law of the place of payment.

English translation for reference only; the Chinese text prevails. Not legal advice.
