The paperwork is as good as the breeders word.

I could take a pic of 2 pieds put them on a card and put a pic of a normal and say the 2 pieds are the parents.

could this be true? Yes

Could it be false? Yes

There is no blood working being done by a third party to verify their the parents lol.

So as i said its useless, its pretty much to guarantee the genetics in case for some odd reason it doesnt prove out or if you ever go to resell the het.
