Hi, Steve:  I'm from PA, not OH.  I dont' abstact.  I examine.  I expect an abstractor to run all names for a sufficient length of time to cover IRS liens which would attach to after-acquired property.  You have to run the names for 10 years and 30 days.  I agreed with Douglas because his answer would include the IRS liens and also any other lienable items in the same category, leaving open the possibility that OH may have a lien that exceeds the IRS timeline.
