Tell them to stop. Dont be hard...there old people!
It depends entirely on the grandchild's legal guardian(s). They have control over the affairs of the child, so if the grandparents may or may not be permitted to see their grandchild.
Biologically, the grandchild is a step-grandchild to the grandparent that had no children. In matters of the heart, however, the grandchild is whatever the grandparent feels it is.
Child support for the grandchild is the responsibility of the grandchilds father, not the grandchild. If the father is a minor, you can take his parents to court for support.
Only with adoption.
yes if the grandparents put you on child support.
It depends on what the courts decide as to the law. However in terms of what is right, the father should continue to pay child support until the children are 18 or out of high school.
You are the grandchild of your grandfather. If that grandfather had children other than your parent, and that child had a child - that person is your first cousin and also a grandchild of your grandfather. Your first cousins are, by definition, all those who are not your siblings but are also grandchildren of one of your grandparents. Remember that you have two sets of grandparents. Those first cousins who are related to you through one pair of grandparents are not related to your other grandparents at all.
Whether the grandparents have access to their grandchild or in this case step grandchild, is entirely up to the parents. They decide who will have access to the child and they might favor someone who is not a blood relative. Step grandparents can be just as good as blood related ones.
If the step-dad has or shares custodial authority, he can prevent the child seeing grandparents for any reason.
no
Yes, and they should also file for child support from both parents.
It's doubtful that the court would find such action to be in the child's best interests.
