Ohio Revised Code Title XXI. Courts Probate Juvenile § 2151.43

In cases against an adult under sections 2151.01 to 2151.54 of the Revised Code, any person may file an affidavit with the clerk of the juvenile court setting forth briefly, in plain and ordinary language, the charges against the accused who shall be tried thereon. When the child is a recipient of aid pursuant to Chapter 5107. of the Revised Code, the county department of job and family services shall file charges against any person who fails to provide support to a child in violation of section 2919.21 of the Revised Code, unless the department files charges under section 3113.06 of the Revised Code, or unless charges of nonsupport are filed by a relative or guardian of the child, or unless action to enforce support is brought under Chapter 3115. of the Revised Code.

In such prosecution an indictment by the grand jury or information by the prosecuting attorney shall not be required. The clerk shall issue a warrant for the arrest of the accused, who, when arrested, shall be taken before the juvenile judge and tried according to such sections.

The affidavit may be amended at any time before or during the trial.

The judge may bind such adult over to the grand jury, where the act complained of constitutes a felony.
