Questão jurídica principal
Whether the 8 April 1991 letter satisfied the formal requirements for pledging the life insurance claim.
Decisão extraída
Yes. A signed written declaration by the pledgor, containing the essential terms, together with delivery of the policy and written notice to the insurer, validly created the pledge.
Fundamentação extraída
Art. 73 LCA and art. 13 CO require written form and delivery; no formal pledge deed is necessary. Only the pledgor's signature is needed, and the creditor's consent may be oral or tacit.
