Adoption can be a complicated area of family law, but it is also a rewarding one for the families. There are many reasons why people in Illinois adopt children. Sometimes a child is adopted by a step-parent or by another relative if the biological parents can no longer care for the child. Other times the couple attempting to adopt is not able to have children of their own or they may be a same sex couple and want to have a family. In these cases, people can adopt children living in the United States or look internationally to adopt a child.
