    The Center-of-Life Test: What Documentation Actually Works

    When the 150km rule is contested, the center-of-life test decides it. The practical evidence stack: rentals, registrations, tax residency, schools.

    When the 150km rule is contested, the center-of-life test decides the case. The standard that works is two or three independent documents per period, covering housing, registration, and economic activity.

    What counts as evidence

    • Rental contracts or property deeds with addresses and dates.
    • Utility bills tied to the same address.
    • Municipal or national registration certificates from the country of residence.
    • Employment contracts and payslips showing where you worked.
    • Tax residency certificates for the relevant years.
    • School enrolment letters for children, if applicable.
    • Health insurance enrolment in the country of residence.

    How to present it

    A simple residence timeline at the front of the annex, then the documents grouped by period and country. One PDF per period, named by date range, beats a single 80-page dump. The reviewer's job becomes scanning your timeline and confirming each entry, not reconstructing your life from raw documents.

    What does not work

    Self-declarations, social-media history, photos, and letters from friends carry little weight on their own. They can support a thin file but cannot replace the formal documents.
