can you explain grandparents rights in Virginia

I assume you are referring to a grandparents rights to custody or visitation with a grandchild? This is a very complex issue, that in order to answer what your options are, would require a specific fact scenario.  The answer depends on which (custody or visitation) you are seeking, are both biological parents involved, are either or both in favor of you taking custody or having visitation with the minor, has the child been removed from the home....and on and on.  If you would, please be more specific on who is involved and your goal for the child.
