How much of your paycheck may be garnished to pay child support depends on whether you are currently supporting another spouse and/or child, other than the child who is the subject of the child support order. If so, up to 50% of your disposable income (what's left after mandatory deductions) can be garnished and sent to the child's other parent. If you aren't currently supporting anyone, up to 60% of your disposable income can be garnished for child support. These amounts are higher than the limits set for most other types of wage garnishments (for student loans or lawsuit judgments, for example). For more information on wage garnishments, see Nolo's article If Your Wages Are Garnished: Your Rights.
