As of May 1, 2018, it will no longer be necessary to submit the original of the deed of ownership to prove the accommodation to the Foreign Police. The declaration of the owner/owners on providing the accommodation or a rental agreement is sufficient. The signatures must be notarized and the document must not be older than 90 days.
Nevertheless, we recommend that you provide at least an informative deed of ownership from the Internet.
