This issues raises the question of the presumption of paternity. That is that historically, children who were born as the product of an intact marriage are presumed to be the product of the marriage. That means that Mrs. A is married to MR. B, but having an affair with Mr. C. Even though the child may be biologically Mr. C’s child, in Pennsylvania, if Mr. B accepts the child as his and does not question the legitimacy, then it is unlikely that Mr. C. will be able to intervene in anyway into a custody litigation.
However, this presumption has begun to change over time, and it is possible to call this presumption into question if there are issues of access or impossibility. . For example, if Mr. B was sterile or stationed overseas in the military when the child was conceived, the court would be more likely to be willing to grant a paternity test or allow Mr. C standing to seek custody of the child. However, if Mr. B and Mrs. A are presenting a united front, it will likely be hard for Mr. C to get his day in court.
