http://www.schaarbeek.be/site6/plone/demarches-administrativ...there is now way i can help you to get that death record as it is prohibited by law , only relatives may get it and they must ask it themselves ...sorry for it , i can t change the law.As these records are private and less than a century old ; it s considered as private by law ; yu are the only one able to get it ..It just is so
Best regards
