I am trying to figure out if I would have any rights to my half siblings for visitation?

I have provided for them in the pass until relationship with parent/step parent went south. They currently are not allowing me to see my siblings and are stating that I will never be able to see them again. My siblings have made comments to our parents that they wish to see me. I have documentation that they have told the kids that they are not allowed. I am concern for my siblings and their well being if I am not allowed to be in their life. I have taken care of them since birth up until two years of their life. Once our parents became active in their life I took a back seat but had regular visitation.

Please assist. I am lost at what to do and I really miss them. I would like to avoid going to court at all possible because I do not want the kids to have those images. Please let me know if I have a case.

The short answer is no, you don't. Like most states, Missiouri only provides statutory recognition of grandparent rights, and those are only possible under some very specific circumstances (death or divorce of parent, or if they have acted as guardian of the child for some substantial amount of time). Other persons, whether family members or not (including siblings, half-siblings, etc.) can petition the courts for custody of the child, but such a petition generally isn't going to be successful unless the current parents or guardians are found to be unfit (or unless they die, have abandoned the children, etc.). In other words, unless the court finds that the parents are unfit guardians, such that the children should be taken away from them, the courts will side with the parents in determining who can and cannot have visitation.
