Thanks Jaebin for your imput.
I actually misread the piece of legislation that I was looking for. I should have been looking at 68 not 6B as I initially thought. I got this info from a You Tube still, so I will give myself a break on that one.
I should have picked this up earlier and sort of did. the text of the section didn’t marry up to the apparent purpose of including it on the birth certificate.
