1. An antenuptial contract clause requiring payment if an extramarital affair is 'the cause' of divorce must be interpreted purposively in context; where designed to preserve marriage by deterring infidelity, causation is established if the affair destroys trust leading to marital breakdown, without requiring narrow application of legal causation principles. 2. An exclusion clause in an antenuptial contract providing that assets are excluded from accrual together with 'any other asset acquired by such party by virtue of the possession or former possession of such asset' requires proof of a direct nexus between the specifically excluded asset and the asset claimed to be excluded; the phrase means 'the particular asset, its proceeds, and assets which replace the excluded asset or are acquired with its proceeds' and does not extend to all assets acquired through general involvement in the same industry. 3. A spouse has standing to seek to pierce the trust veneer when enforcing an accrual claim, even though not a trust beneficiary or third party transacting with the trust, where the unconscionable abuse of the trust form by the trustee through fraud, dishonesty or improper purpose prejudices enforcement of the obligation owed to the spouse. 4. To succeed in piercing the trust veneer in the matrimonial property context, a spouse must prove the trustee transferred personal assets to the trust and dealt with them as trust assets with the fraudulent or dishonest purpose of avoiding the obligation to account for accrual and evade payment, or that transfers were simulated to retain ownership while cloaking assets with trust form. 5. Poor trust administration, disregard for fiduciary duties, and failure to maintain separation between control and enjoyment, while potentially justifying removal of a trustee, do not alone justify piercing the trust veneer without proof of fraudulent intent to defeat the spouse's patrimonial claim. 6. The word 'contributions' in an antenuptial contract providing that contributions to a trust are subject to accrual means any asset that accumulated in the trust after marriage, irrespective of how accumulated, and is not limited to voluntary acts benefiting the trust without legal obligation.
