I think that the only ones who can answer this would be Swiss kennel club SKG:

In some limited cases different kennel clubs will issue papers provided parentage can be proven, but it is individual to each kennel club.
If the puppies did not come with papers and the reason is that they were accidental, I assume the country from where they came have some stipulations on breeding rights which the parents did not (or not yet) meet and that's why they were unable to get papers..? So it depends too where they are from, and if the breeder is even willing to cooperate, too.
