When the other person lives outside of Nova Scotia and you would like to establish or change support (child or spousal support), there may be a cross-border process available to you. This process is forms-based and may be referred to as the interjurisdictional support order (ISO) process. There are two laws that deal with this process: Nova Scotia’s provincial Interjurisdictional Support Orders Act or “NS ISO” and the federal Divorce Act or “Divorce Act ISO”.
