I don't think any of the hets I have came with paperwork, other than a 66% poss het hypo male I bought. I researched and trusted the info I was able to find on the others I bought from. Paper work matters very little to me. I don't think fake hets are as prevalent as many others seem to believe, but I'm sure there are a few people here and there that have no issue misrepresenting genetics...and I think that most instances where genetics are not as they are sold are probably a result of ignorance/not understanding rather than intent to deceive.
