Can i file for an annulment in ohio if married for less than a year and have no children and no property together

You cannot file for an Annulment just because you have  been married  less  than a year and have no children or property.  You must meet one of the conditions of the statute to file and be successful in your filing. For example, one of the conditions is "no-consumation of the marriage."  You should consult  with an attorney regarding your  situation and goals.
