i moved to oklahoma & had to establish residency to file for divorce. the divorce was final and i remarried, spur of the moment while on vacation. i was advised the marriage was not legal as oklahoma law states you cannot remarry within 6 months of a divorce. we considered the marriage void and do not live together. we are now advised that we may have to file for annulment. what do we do? is our marriage void? is an annulment necessary?
