How do you sue a landlord in another state?

You sue a landlord in which ever state you signed the lease and retained the property in. If the landlord resides in Toledo, Ohio and you rent a property and signed your lease in Monroe, Michigan, you sue in Monroe, Michigan.

However, if your lease specifies that any civil proceedings must take place in the landlords state of residency, you're bound by the contract to file suit in the landlords state of residency.
