The letter should also indicate a date on which the child support agreement will be reassessed. The letter should accurately represent the decision of both parents and both parents should sign the letter before it is approved by a judge. Party 1 shall not be required to pay family allowances retroactively to Part 2 for the period preceding this Agreement. The nature of the information required varies according to the sources of income. The field examples apply to situations where the payer is an employee. Any adjustment of the child`s support in accordance with this clause does not apply retroactively, but applies from the date of verification. The modalities of maintenance of any children are decided by the judge during the divorce proceedings. However, some people may not want to go to court and are willing to voluntarily pay family allowances and grant an amount. Each of us must immediately inform the other as soon as we become aware of a substantial change in circumstances that could affect the child`s maintenance obligations. Although, as you see above, there are several ways to establish a child custody agreement, it must ultimately be in writing and signed by both parties in order for it to be implemented. . . .
