It should be noted that after reviewing your inquiry and legal scrutiny we would like to inform you that a travel ban can result from any number of causes.

between borrowers and lenders
landlords and tenants

Or due to their non-payment of fines pertaining to traffic, commerce or municipality offences

If a financial dispute is the basis of the travel ban, it may be possible to get the ban lifted by depositing a sum of money equal to the amount in dispute with the court.
