Changes the 2016 Holocaust Expropriated Art Recovery Act to strengthen the right of victims and heirs to recover art and property taken because of Nazi persecution. It bars certain time‑based and procedural defenses, allows suits even when a covered government or its agent was involved, permits nationwide service of process, and makes the changes apply to claims pending when the law is enacted and to claims filed later. The amendments add findings that explicitly allow recovery claims despite delays and remove defenses like laches, adverse possession, act of state, forum non conveniens, and international comity. The bill also treats covered claims as "rights in violation of international law" for jurisdictional purposes and includes a severability clause.
