Ohio Code § 2117.42

§ 2117.42.

If, in the cases specified in section 2117.41 of the Revised Code , more than one person is liable for the debt, the creditor shall proceed by one action

to recover the debt against all so liable, or as many of them who are within the reach

of process.  By the verdict of a jury if either party requires it, the court shall determine

what sum is due to the plaintiff.  The jury also, according to the equities of the case, shall decide how much each

of the defendants is liable to pay toward the satisfaction of the debt and the court

shall render judgment accordingly. No suit shall be dismissed or debarred for not making all the persons defendants who

might have been included as defendants.  In any stage of the cause the court may award process to bring in other parties

and allow amendments necessary to charge them, as defendants, upon the terms that

it considers reasonable. If any of the persons who were originally liable for the debt is insolvent or unable

to pay the person's proportion, or is beyond the reach of process, the others nevertheless

shall be liable to the creditor for the whole amount of the debt;  except that no

one shall be compelled to pay more than the amount received by the person from the

decedent's estate. If, in consequence of insolvency, absence, or other cause, any of the persons liable

for the debt fails to pay the person's just proportion to the creditor, the person

shall be liable to indemnify all who, by reason of that person's failure, have paid

more than their just proportion of the debt, such indemnity to be recovered by all

of them jointly or in separate actions, by any one or more of them for their respective

parts, at their election.
