Under Oregon law, there's no such thing as "main" lease holders. Either your roommate's on the lease, or she isn't. Either way, though, you can't legally evict her at all. That's a right only the landlord maintains. And, depending on what the landlord advised you to do, there's really no easy/clean way to "remove" her from the lease and thus there really is no set procedure for giving her time to vacate, etc. You can hope she acquiesces, but if she doesn't and otherwise attempts to enforce her rights to occupancy of the unit under the lease, she'll likely be able to. In addition, I'd be wary of trusting your landlord's advice on how to go about this process, as they're not necessarily a disinterested party. The easiest way to go about the process, of course, is if your roommate simply agrees to move out, brings her past due rent up to date, and then all is well. Failing that, your landlord may have to go through the process of securing an eviction, via the court's FED procedure (something you cannot do). Depending on the terms of the lease and other facts, you can have all parties to the lease (landlord and all tenants) sign a amendment that changes the parties to a lease, but if there's any potential for a problem or an issue, you might be best served to terminate the current lease, if you can, and then sign a new lease with the landlord for the property.
