Siblings can often be separated for a variety of reason. Reasons can include foster care placement, adoption, and divorce. 

"State governments regularly make decisions that affect theday-to-dayy
situation of the family. State courts determine the placement
of children in custody disputes and decide whether siblings should
be separated. State agencies determine the outcome of sibling separation
in adoption and foster care cases. Additionally, state legislatures
have the power to provide a procedural mechanism to
facilitate sibling visitation." (http://scholarship.law.cornell.edu/cgi/viewcontent.cgi?article=2498&context=clr 

"In addition to state court determinations of whether siblings
will be separated, state legislatures may also play a role in defining
sibling rights. State legislators may provide procedural vehicles
which facilitate sibling visitation after siblings are separated. Indeed,
several state legislatures have responded to the separation of
siblings by enacting provisions to facilitate visitation" (http://scholarship.law.cornell.edu/cgi/viewcontent.cgi?article=2498&context=clr 

While, Ohio's does allow for Thrid-Party Visitation, it does not specifically  recognize the right of siblings visitation. Acceptance of siblings rights will encourage the Supreme Court to recognize the significance of these special relationships.

The Supreme Court has not ruled on whether children have a constitutional right to sibling visitation. However, the Supreme Court has made several rulings which indicate a likelihood that if it ever came before the Supreme Court it likely would. 

As a former foster youth, I know foster youth that the system separated and the heartache it caused.  I have a child of my own who hurts deeply because she was seeing her half-siblings, only for her father to rip them out of her life and never let her see them again. 

Children should not be deprived of these important relationships because of flaws in the state's foster care system or wrongful death. In addition, a child should not be deprived of relationships with siblings simply because of animosity between the parents. 

While parents do have the constitutional right to parent and make decisions for their children and who they associate with, this right should be deemed equal to the child's right to sibling visitation. Instead, the statute should allow for in these circumstances for the best interest of the child standard to apply.
