1. You have mentioned that your husband was divorced from his first wife as he did not turn up to contest the divorce case filed by him. Once a court of law has passed a judgment granting divorce to a person he/she does not require any validation from the church or any other religious institution.
2. Was a copy of your marriage certificate sent by the minister to the registrar for registration? A church marriage certificate has no legal validity if it has not been registered. You can file or divorce any time on the ground of mental and physical harassment meted out to you if a valid marriage has been solemnised. A christian marriage is to be mandatorily registered in accordance with the law. If the marriage certificate was not sent to the registrar then it may be sent now subject to the law, else it will be futile for you to go to court for divorce.
