Questão jurídica principal
Whether the inheritance contract contained a gap regarding the allocation of assets if D.'s mother claimed her reserved share.
Decisão extraída
The contract left that situation unregulated and had to be supplemented according to the parties' hypothetical intent.
Fundamentação extraída
The wording and context did not show that the parties had regulated the effect of E.'s reserved share claim; the trust-based interpretation pointed to equal treatment of both sides.
