Questão jurídica principal
Whether the general conditions and forum clause were validly incorporated without the debtor's signature on the acknowledgment section.
Decisão extraída
The conditions were incorporated by the signed 15 November 1988 declaration; no separate signature on the conditions was required.
Fundamentação extraída
A party signing a document expressly referring to general conditions is bound by them. The wording of the declaration showed that the signatories, including the debtor, had received and taken notice of the conditions, and nothing indicated that a further signature was agreed as a validity requirement.
