Internal auditors and implementation help

1) Is it possible for someone who doesn't have a certificate to be an auditor? Is experience enough?
2) Can a company without ISO certificate conduct an ISO process or help another company / business to be ISO certified? Isn't a legal issue?”

Answer:

It is up to the client of the audit to specify the requirements of competency to be an auditor. Different clients will have different requirements. Interestingly, the last version of ISO 19011 removed competency requirements from the auditor definition.
There is no legal issue involved. A company without ISO certificate can help a company / business to be certified. Naturally, a certified company con argue commercially that it has first-hand experience of the process.
