Key legal question
Whether clause 2.22 of the 1973 inheritance contract bound the surviving spouse or was freely revocable.
Extracted holding
Clause 2.22 was a unilateral testamentary clause, not a bilateral contractual commitment, and could therefore be revoked by the surviving spouse.
Extracted reasoning
The wording, structure, purpose of mutual spousal enhancement, and especially the absence of any binding interest of the deceased spouse toward the plaintiffs showed no contractual binding intent. The broad disposal power in clause 1.13 also pointed against a restriction.
