Ohio Code § 2105.15

§ 2105.15.

A person of sound mind and memory may appear before the probate judge of the person's

county and in the presence of the judge and two disinterested persons of that person's

acquaintance, file a written declaration declaring that, as the person's free and

voluntary act, the person did designate and appoint another, stating the name and

place of residence of the other person specifically, to stand toward the person in

the relation of an heir at law in the event of the person's death.  The declaration shall be attested by the two disinterested persons and subscribed

by the declarant.  If satisfied that the declarant is of sound mind and memory and free from restraint,

the judge shall enter that fact upon the judge's journal and make a complete record

of the proceedings.  From then on the person designated will stand in the same relation, for all purposes,

to the declarant as the person designated could if a child born in lawful wedlock.  The rules of inheritance will be the same between the person designated and the

relations by blood of the declarant, as if so born.  A certified copy of the record will be prima-facie evidence of the fact stated in

the record, and conclusive evidence, unless impeached for actual fraud or undue influence.  After a lapse of one year from the date of the designation, the declarant may have

the designation vacated or changed by filing in that probate court an application

to vacate or change the designation of heir;  provided that there is compliance with

the procedure, conditions, and prerequisites required in the making of the original

declaration.
