i completely agree, all contacts should always be seen by your legal rep, so that when the new puppy owners take the pup, they are legally bound by the terms and coinditions of the document. you must be very vidulent, fair and pick the right owners for your puppies anyway and not just give them to anyone that you dont trust. your puppies are precious and you wouldnt forgive yourself if anything happened, so a legal rep is certainly the right way to go when putting the contract together and when both you and the new owner sign the documents.
