French to English Law/Patents General / Conversation / Greetings / Letters Sale of property

"le vendeur a, de bonne foi, réuni les documents et informations notamment en matière juridique, technique, fiscale, environnementale et administrative constituant le Dossier d’Information (en ce compris les réponses formulées ou non aux questions posées par l’Acquéreur et ses conseils)"

"accompagné de ses conseils, professionnels expérimentés et choisis par lui, l'acquéreur a effectué un audit des Biens Immobiliers, examiné et analysé le Dossier d’Information, posé des questions écrites ou orales et analysé les réponses formulées ou non;"

In the first instance you might be tempted to read this as 'answers, whether or not formulated in response to questions asked by the Purchaser'. However, in the second instance this is not an option!

I'm wondering therefore what it really means, and what a 'réponse non formulée' might mean? In a more informal context, this would mean an answer given without thinking. In this more formal context, could the distinction be between written and non-written replies; standardised and personalised replies; or 'full' and 'one-word' answers?
