There are two ways to solve the problem: one is to negotiate between the husband and wife, and the other is to sue in the court. These are the two main approaches. In addition, the amount of child support can be determined according to the actual needs of the children, the affordability of both parents and the actual local living standard. If there is a fixed income, alimony may generally be paid at the rate of 20% to 30% of the total monthly income. For those who bear the maintenance fees for two or more children, the proportion may be appropriately increased, but generally shall not exceed 50% of the total monthly income; If there is no fixed income, the amount of alimony may be determined according to the total income of the current year or the average income of the same industry, with reference to the above proportion; In case of special circumstances, the above proportion can be appropriately increased or reduced. The alimony shall be paid regularly, and can be paid in a lump sum if conditions permit. If one party has no economic income or is missing, his or her property can be used to offset the alimony. How to allocate maintenance fees for divorce by agreement If the husband and wife are divorced by agreement, the other party should perform its obligations according to the Divorce Agreement reached by both parties voluntarily, or file a lawsuit to the court according to this agreement to ask for payment of child maintenance fees; If the divorce is mediated by the court, in addition to the Divorce Mediation Statement, there should also be a divorce property division agreement, which should contain provisions on child support. If the party who does not directly support the child refuses to implement the provisions, it can sue again to the court, let the court re adjudicate, and request compulsory implementation; If it is a divorce judgment, it can be required to pay child support according to the divorce child support payment terms in the divorce judgment.
