My original documents (e.g. birth registration, marriage registration, and family registration certificate etc.) are already legalized by the Embassy of the Netherlands (in my home country).
I guess my above stated documents should also be recognized by the competent authorities of other Schengen countries as per the agreements between EU/Schengen countries. Hence, I should get exemption of documents legalization in case if I am applying for long-term visas/residence permit in another Schengen country. Or will I need to legalize my documents again and again from the respective embassies wherever I will be applying to long-term visas/residence permits in future.
It would be really big help if anyone can show me any reference (law/regulations) either to prove or disprove my above guess.
