Life`s situations are constantly changing. When these changes occur, support agreements and contracts often need to be changed. This is necessary to ensure that support agreements and orders remain fair. You still have to pay family allowances, even if you don`t see your children. Also check your written agreement to check the end date of the assistance to the children. In most cases, the cessation of payments occurs when the child reaches a certain age or level of education. This agreement allows parents to amend an existing support agreement or establish a new child support agreement. Family allowances are usually based on a calculation that will assess the time each parent spends with the child and the parents` income and wealth. You will find a number of family allowance calculators online. .
