Read the following excerpt from a US court opinion:
```
that in custody disputes, “the fundamental issue is the best interest of the child.” In a custody contest between two biological parents, “the burden of proof is shared equally by the contestants.... ” Yet, where the custody dispute is between a biological parent and a third party, the burden of proof is not evenly balanced. In such instances, “the parents have a ‘prima facie right to custody,’ which will be forfeited only if ‘convincing reasons’ appear that the child’s best interest will be served by an award to the third party. Thus, even before the proceedings start, the eviden-tiary scale is tipped, and tipped hard, to the [biological] parents’ side.” Id. at 339, 744 A.2d at 1258 (2000) (citations and quotations omitted); see also T.B. v. L.R.M., 753 A.2d 873 (Pa.Super.2000)  aff'd, 567 Pa. 222, 786 A.2d 913 (2001). ¶ 8
