Spokane residents know that life is expensive, especially when children are involved. Whether it is clothing and food expenses, medical care, extracurricular activities or other expenses, the list of children's needs is almost never-ending. Raising a family can be financially taxing for many couples. The financial burden can become even greater after a divorce, however, when one parent may end up providing for most of the child's daily needs. Although child support is designed to provide for the welfare of children and initial determinations rely on a variety of factors, sometimes modifications of child support become necessary.
