Your first post/thread is closed.....don't know why. I don't know AR law, but your ex could be right......my ex's wages are garnished and on the bottom of the order to withold, after it specifies the exact amount to withold each payday, it says: "The total withheld amount cannot exceed 50% of the employee's/obligor's aggregate disposable weekly earnings". I believe this is protection for the employee so if for some reason his earnings decrease, he will still get paid at least half his earnings after the garnishment.
New baby: This will not affect your current order unless he gets it modified to include the extra expsenes of another child to support. If he does this, unless his income has increased, your CS will probably decrease.
