You can file for child support once you are living separately. Depending on how much you each earn - since Ohio uses the "shared income" model of calculating child support - he or you could end up paying even with a 50-50 timeshare.
It's very very easy to start the process in Ohio and assuming the child/ren were born during the marriage, he will be considered the legal father and there will be no need for DNA testing (unless he wants to dispute paternity). It could take several months depending on how busy the courts are, and the amount is usually retroactive to the date you file.
