Estoppel by representation does not require knowledge by the representor of the facts giving rise to the estoppel or of the representee's detrimental reliance; such a requirement applies only to estoppel by acquiescence.

The reasonableness of a lay purchaser's reliance on such a document is not determined by what a competent solicitor would advise, absent evidence that the purchaser was so advised.
