Garnishment is a legal process that is only available after you obtain a judgment. So, you must sue your son first (or have him sign a consent judgment) before you can garnish any wages. It is possible for your son to authorize automatic withholding on each paycheck of a certain percentage or dollar amount. This would be voluntary and could be stopped any time by your son. But it would also have the features of a garnishment... that is, money taken out of each paycheck.
