30 day lease landlord tenant laws in Ohio

[Kevin Bieber]

Hey guys-

I wanted to check if i have any recourse in my current situation.  We were staying in an apartment and decided to extend our lease by 30 days.  We signed the lease and sent in notice 30 days prior to end of the lease term.  Upon turning in the keys, the office said we were required to give a 45 day notice and because of that we would have to pay for it seems like those extra 15 days we didn't give notice on.  So basically we were given a 30 day lease that had a 45 day notice requirement.  I signed it (my mistake missing the 45 day) but i have found some statutes that say only 30 days is required under state law.  What takes precedence here?  Any docuemtnation or experiences would be great!
