An annulment classifies a marriage as void, and the marriage is treated as though it never existed between the two parties. In Ohio, an annulment may be granted by the court for several reasons. For example, a court will grant an annulment if one of the spouses was married to another person at the time of marriage or if the spouse seeking the annulment was a minor at the time of marriage. In addition, an annulment may be granted if the marriage was obtained by fraud, force or if either spouse is determined to be mentally incompetent. If the marriage was never consummated, an annulment may also be available to you. For more information about the grounds for an annulment in Ohio, see http://codes.ohio.gov/orc/3105.31.If you can show that you are eligible for an annulment due to one of the preceding circumstances you can ask the court for an annulment even if your husband is currently incarcerated. However, your husband’s incarceration on its own is not a valid ground for an annulment. In addition to the difficulty of proving an annulment is necessary, you may also have a difficult time serving your husband with a copy of your request for an annulment due to his status. Therefore, you should contact an experienced family law attorney to determine the best way to proceed with your case.
