While renting out their property, landlords/licensors are required by law to get police verification of their tenants/licensees done. It is important to note that this is not optional.
This process is done mainly for security reasons, so as to verify your background and check the details of past residence/family/criminal record (if any) etc.
If they do not comply with this process while making the rent/lease agreement, the owner can be punished jail time and/or fine. However, no action will be taken against the tenant.1
