Consequences for not paying child support include:

 -- Suspension of your Driver’s License-A.R.S. 25-320.01

 -- Suspend or take away Professional, Occupational or Recreational Licenses

A.R.S.25-320 K states boards that issue Professional, Occupational, or Recreational Licenses and/or Certificates will keep social security numbers on file so as to aid the Department of Economic Security in locating parents or to enforce child support orders.

  -- Mandatory wage withholding (keeping part of each paycheck)

  -- Intercept state income tax refund (keeping part of a tax return)

  -- Liens against real and personal property

  -- Non payment reported to credit reporting agencies
