The Arizona Petition To Modify Income Withholding Order (ALAMO) is a legal document used to request a change in the amount of money being withheld from an employee’s wages for child support or spousal maintenance. It is typically filed with the Arizona Superior Court in the county where the employee resides. The ALAMO can be used for either a temporary or permanent modification of the withholding order. The types of Arizona Petition To Modify Income Withholding Orders include: Temporary Modification of Withholding Order, Permanent Modification of Withholding Order, and Voluntary Withholding Order. The Temporary Modification of Withholding Order is used to modify the amount of money being withheld from wages for a specific period of time. The Permanent Modification of Withholding Order is used to change the amount of money being withheld from wages for an indefinite period of time. The Voluntary Withholding Order is used to voluntarily begin withholding money from wages for child support or spousal maintenance.
