Washington state law recognizes that grandparents have some rights to see their grandchildren, but these rights are more limited than parental rights.
American courts have long recognized that the Constitution grants parents fundamental rights to make important decisions about the upraising of their children. This can mean that a parent has the right to decide their children should not spend time with their grandparents. However, Washington law recognizes that grandparents, and sometimes others, have rights as well, and courts can take these into account.
