Raising a teenager often costs more than raising a younger child. As a parent in Washington, you might be paying or receiving child support that was calculated years ago. When your teenager’s costs go up, you have options to address these changes without turning your family life into a courtroom battle.
How does Washington calculate child support?
Washington uses the Economic Table Schedule to set baseline child support amounts. The state looks at both parents’ combined monthly income and the number of children who need support. This creates a basic support obligation, which both parents then split proportionally based on what they earn.
The standard calculation covers ordinary expenses like food, housing and clothing for children of all ages, including teenagers. However, certain extra or specialized expenses often require separate treatment by the court.
What additional expenses can modify support orders?
Washington law lets courts adjust child support amounts for certain extra expenses. These may include costs for education, activities and special needs. When your teenager plays sports, takes music lessons or enrolls in advanced courses, these expenses might justify a change. Healthcare costs beyond basic insurance also count as possible adjustments to the support amount.
When should you consider requesting a modification?
If your teenager’s expenses have gone up since the original support order, you may have grounds for modification. To modify a child support order in a Washington court, you must generally show a substantial change in circumstances that was not anticipated when the original order was entered.
Common situations include private school enrollment, ongoing medical treatments or competitive sports programs. Gather documentation of these expenses before filing a modification request. Bank statements, receipts and invoices can help show the financial impact.
Supporting your child’s development
Your teen’s growing needs deserve proper financial consideration. The state recognizes that raising older children often requires more resources. By staying informed about modification options, you can work toward an arrangement that helps your teen thrive during these important years.
