Courts in Pennsylvania are most concerned with the best interests of the child anytime they are considering custody. This 'best interests' standard also applies in those cases where a grandparent is attempting to gain some kind of custody of their grandchildren.
To participate in custody or dependency proceedings in Allegheny County, Pennsylvania, one must have what is known as standing. Standing is the term used to acknowledge a legal basis and right for an individual or individuals to sue in a court of law. For example, a biological mother always has standing to sue a biological father for custody. Her legal basis and right comes from her standing as a parent.
