At present, it is a simple and convenient choice to divorce foreigners by agreement. If both parties can reach an agreement on divorce through consultation, including children, property and debts, they can choose litigation mediation or divorce registration. If the foreign-related agreement divorce is considered, it should also consider whether each country or region has set up a registration divorce system, that is, an administrative divorce system. Some countries can only divorce through litigation, such as Germany, the United Kingdom, France, the Netherlands, including Hong Kong. Some countries or regions adopt both litigation divorce and administrative registration divorce, such as Japan, Portugal, Romania, Cuba, Haiti, Mexico and Taiwan. Even in some countries and regions where administrative procedures are allowed to register divorce, there are certain restrictions. Generally speaking, if the registration method is adopted, the parties shall be present in person. For the marriage between mainland residents and Hong Kong, Macao and Taiwan that can be handled in China, both parties must also be present in person to handle the divorce by agreement. If the party concerned is not present and entrusts others to register the remarriage through agreement, only the overseas students or working abroad of both parties, or the overseas Chinese living abroad of both parties (only if the local authority does not accept their divorce) can entrust lawyers to register the divorce in their original marriage registration place.
