(19)In order to be satisfied that UCITS assets and UCITS rights are protected against a third party insolvency, the depositary has to understand the insolvency law of the third country where a third party is located and ensure the enforceability of their contractual relation. Before delegating the safekeeping functions to a third party located outside of the Union, the depositary has to receive an independent legal opinion on the enforceability of the contractual arrangement with the third party under the applicable insolvency law and case law of the country the third party is located in, in order to ensure that the contractual arrangement is enforceable also in case of insolvency of the third party. A depositary's duty to assess the regulatory and legal framework of the third country also includes the reception of the independent legal opinion assessing insolvency law and case law of the third country where that third party is located. Those opinions may be combined, as the case may be, or issued for each jurisdiction by relevant industry federations or law firms for the benefit of several depositaries.
