Does anyone know if it will be an issue if only one parent (the Mother) name is only on the beneficary's birth certificate? I have a copy of my husband's original birth certificate and it only has his mother name. Has anyone completed this section with only 1 name and had no issues? Per the guideline it states both parents name should be on it.
I'm not quite sure who the beneficiary is here and why the father's name is relevant to your case, so it is hard to answer your question exactly.
In general, a birth certificate that has been amended more than 1 year after child's birth is going to be considered a "delayed" birth certificate and is going to be considered
invalid for immigration purposes. If the father is known (sometimes they aren't!) and their identity is relevant to your case, amending the birth certificate like others are suggesting is only going raise all sorts of suspect flags about the legitimacy of the birth record itself. Instead, the embassy want to see the original birth certificate and any evidence you have of who the father actually is, the same evidence that you'd supposedly have to submit to get the birth record legitimately amended anyway.
My advice - leave the birth certificate alone. Submit proof of paternity as separate, additional evidence.
