26 Rebuttal of presumption as to legitimacy and illegitimacy.E+W
Any presumption of law as to the legitimacy or illegitimacy of any person may in any civil proceedings be rebutted by evidence which shows that it is more probable than not that that person is illegitimate or legitimate, as the case may be, and it shall not be necessary to prove that fact beyond reasonable doubt in order to rebut the presumption.
