I've seen a lot of replies in this thread with a lot of interpretations. All with good intentions, but many contain incorrect or ill advised information. Your friend should NOT contact the landlord to find out what this notice means; he/she absolutely should NOT contact the court to see what this notice means. Your friend should contact an attorney in the area who practices in landlord/tenant law or if there is a local legal aid society, contact them as they likely handle a lot of eviction cases from the tenant's side.
In Ohio, a landlord can give a three day notice to leave the premises ONLY IF the tenant has failed to pay rent. If the tenant promptly pays the back rent and the landlord accepts payment (he does not have to), the landlord may choose not to file an eviction action in court. If the tenant fails to pay the back rent within three days, the landlord may then file a complaint to evict in the local court after three days have passed since providing the notice. Consistent with the individual court's procedures and scheduling, the matter will be scheduled for an eviction hearing at some later date and the tenant will receive official notice from the Court of that hearing date. It will not be set immediately, but will likely be within a few weeks or less. The judge or magistrate will then hear both sides and decide if the tenant violated the lease. At that point, a move out date will be established (most courts will give the tenant a reasonable amount of time after the hearing date to move out).Again, in Ohio, an eviction for any leave violations other than non-payment of rent requires the landlord to provide a 30 day notice to the tenant -- explaining the violation and giving the tenant 30 days to cure that violation. If the tenant fails to fix the problem, an eviction complaint can be filed after that 30 days has passed and the matter proceeds in the same manner as above.
Have your friend contact an attorney to take a look at the notice and give an opinion on the legalities of it.
