The establishment of an EUTF needs to be justified namely by EU added value (its objectives can be better met at EU than at national level), and complementarity (the trust fund should not duplicate already existing and similar instruments).
Ustanovitev tovrstnega sklada mora opravičevati zlasti dodana vrednost EU (njegove cilje je mogoče bolje izpolniti na ravni EU kot na nacionalni ravni) in komplementarnost (skrbniški sklad ne sme podvajati že obstoječih in podobnih instrumentov).
