In Washington state, child support generally ends when a child turns 18 or graduates from high school, whichever comes later. However, for adult children with special needs, the situation can differ. Parents may still qualify for support if the child cannot support themselves due to a disability.
Requesting support for an adult child with special needs
State law allows parents to request continued support if their adult child has a disability that prevents them from becoming self-sufficient. Courts may extend child support past the usual age limit under these circumstances. Parents must provide evidence that the child’s condition significantly impacts their ability to work and live independently.
How the court determines eligibility
When deciding whether to continue child support for an adult child with special needs, the court considers several factors. These include the severity of the child’s condition, their living situation, and the parents’ financial ability to provide support.
If the adult child lives with one parent, that parent may ask the court for additional support to help meet the child’s needs. The court evaluates each case individually, considering all the unique aspects of the situation.
Modifications and enforcement of support orders
If parents want continued support for an adult child with special needs, they can request modifications to existing child support orders. If the other parent is not following the support order, enforcement measures can be put in place to ensure payments continue.
Moving forward
Parents facing the challenge of providing for an adult child with special needs should work with the court to ensure the child’s needs are met. Support arrangements vary depending on the family’s specific circumstances, and the court’s involvement helps ensure the best possible outcome for the child.
