Key legal question
Whether the buyout claim, though relevant in the divorce property division, remained subject to contractual default interest under partnership law.
Extracted holding
Yes. The claim kept its basis in partnership law; its consideration in the matrimonial property division did not exclude default interest under the general rules on debtor default.
Extracted reasoning
The court held that Art. 240 ZGB governs the valuation in the property regime, not the origin of the claim. The buyout claim arose only when the respondent exited the partnership and was then a social-law claim under Art. 579 OR. Therefore, default is assessed under Art. 102 ff. OR, and the divorce judgment did not waive interest.
