In case of separation, where is child custody decided?

Answer

Jurisdiction lies with the court of the child's habitual residence (EU Reg. 2019/1111 «Brussels II-ter») source: Eur-Lex reg. 2019/1111. If the family lives in Italy and the worker commutes to Switzerland, the Italian ordinary court (juvenile tribunal or specialised section) decides. If children reside in Switzerland, the cantonal court applies per LDIP. The 1996 Hague Convention on Child Protection governs cross-border cooperation source: Fedlex SR 0.211.231.011. For cross-border alimony, EU Reg. 4/2009: Italian judgment directly enforceable in CH via certification. The cross-border worker paying alimony can deduct it from Swiss taxable income in NOV (LIFD art. 33). Family mediation is compulsory in Ticino before trial (CPC art. 297).
