Legal Risks in International Art Transactions

This study develops a conceptual and operational framework designed to bridge the structural gap between the normative requirements of international cultural heritage law and the compliance infrastructure servicing cross-border transactions on the global art market, whose annual turnover approximates sixty-five billion US dollars. Within this paradigm, the proposed Continuous Legal Sufficiency Framework integrates a canonical transactional graph, a jurisdictional vector computation module, a multidimensional Evidentiary Sufficiency Index, and a lifecycle controller that dynamically revises stage-transition permissions as the evidentiary configuration evolves. Empirical validation on a corpus of two hundred forty modelled transactional cases and one hundred eighty multi-jurisdictional scenarios yielded a classification precision of 0.87 and recall of 0.83, reducing the omission rate of mandatory legal regimes by 88.6 per cent relative to the governing-law baseline. Sensitivity analysis establishes that transfer authority operates as a threshold variable consistent with the nemo dat quod non habet doctrine, while freeport opacity and correspondent banking chains delimit the framework's operational boundaries.
