Okes are shooting wildly (blindly?!) from the hip
Below is a link to the relevant law. Marrying OCOP, whether with accrual or without, protects your spouse from sharing your potential debts. This is because the accrual is specifically defined as the amount by which your estate's net value at dissolution (divorce/death) exceeds that at commencement (wedding).

Chapter I, paragraphs 4 + 6:
4.
(1)
(a) The accrual of the estate of a spouse is the
amount by which the net value of his estate at the dissolution of his marriage exceeds the net value of his estate at the commencement of that marriage.
(b) In the determination of the accrual of the estate of a spouse—
(i) any amount which accrued to that estate by way of damages, other than damages for patrimonial loss, is left out of account
(ii) an asset which has been excluded from the accrual system in terms of the antenuptial contract of the spouses, as well as any other asset which he acquired by virtue of his possession or former possession of the first-mentioned asset, is not taken into account as part of that estate at the commencement or the dissolution of his marriage;
(iii) the net value of that estate at the commencement of his marriage is calculated with due allowance for any difference which may exist in the value of money at the commencement and dissolution of his marriage, and for that purpose the weighted average of the consumer price index as published from time to time in the Gazette serves as prima facie proof of any change in the value of money.
6.
(1) Where a party to an intended marriage does not for the purpose of proof of the net value of his estate at the commencement of his marriage declare that value in the antenuptial contract concerned, he may for such purpose declare that value before the marriage is entered into or within six months thereafter in a statement, which shall be signed by the other party, and cause the statement to be attested by a notary and filed with the copy of the antenuptial contract of the parties in the protocol of the notary before whom the antenuptial contract was executed.
(2) A notary attesting such a statement shall furnish the parties with a certified copy thereof on which he shall certify that the original is kept in his protocol together with the copy of the antenuptial contract of the parties or, if he is not the notary before whom the antenuptial contract was executed, he shall send the original statement by registered post to the notary in whose protocol the antenuptial contract is kept, or to the custodian of his protocol, as the case may be, and the last-mentioned notary or that custodian shall keep the original statement together with the copy of the antenuptial contract of the parties in his protocol.
(3) An antenuptial contract contemplated in subsection (1) or a certified copy thereof, or a statement signed and attested in terms of subsection (1) or a certified copy thereof contemplated in subsection (2), serves as prima facie proof of the net value of the estate of the spouse concerned at the commencement of his marriage.
(4) The net value of the estate of a spouse at the commencement of his marriage is deemed to be nil if—
(a) the liabilities of that spouse exceed his assets at such commencement;
(b) that value was not declared in his antenuptial contract or in a statement in terms of subsection (1) and the contrary is not proved.
