Ohio Rev. Code § 4141.41
Any nonresident employer who exercises the privilege of having one or more individuals perform personal services for the nonresident employer within this state and any resident employer who exercises that privilege and thereafter removes from this state shall be deemed thereby to appoint the secretary of state as the employer's agent and attorney for the acceptance of process in any civil action under this section. The director of job and family services in instituting an action against any such employer shall cause such process or notice to be filed with the secretary of state and such service shall be sufficient service upon such employer, and shall be of the same force and validity as if served upon the employer personally within this state; provided the director shall forthwith send notice of the service of such process or notice, together with a copy thereof, by registered mail, return receipt requested, to such employer at the employer's last known address, and such return receipt, the director's affidavit of compliance with this section, and the copy of the notice of service shall be appended to the original of the process filed in the court in which such civil action is pending. The court in which such action is pending may grant continuances to afford such employer a reasonable opportunity to defend the employer's interests.
The courts of this state shall recognize and enforce liabilities for unemployment contributions imposed by other states which extend a like comity to this state.
The attorney general may commence action in any other jurisdiction by and in the name of the director to collect unemployment contributions, forfeitures, and interest legally due this state. The officials of other states which extend a like comity to this state may sue for the collection of such contributions in the courts of this state. A certificate by the secretary of state under the great seal of the state that such officers of the department as designated by the director have authority to collect the unemployment contributions shall be conclusive evidence of such authority.
No person residing in this state shall willfully make a false statement or representation or knowingly fail to disclose a material fact to obtain or increase benefits or payments under the unemployment insurance law of any other state.
The attorney general may commence action in this state as agent for or on behalf of any other state to enforce judgments and liabilities for unemployment insurance taxes or contributions due such other state if such other state extends a like comity to this state.
