Short answer. No. A waiver of rights, shares and effects of the absolute community during the marriage cannot be made except in a judicial separation of property. Where a waiver is allowed, it must appear in a public instrument and be recorded, and the waiving spouse's creditors may petition to rescind it.

A prohibition, not a formality problem

The rule is absolute in its own terms: no waiver during the marriage, full stop, with a single exception for the case of judicial separation of property. This is not a rule about how a waiver must be documented. A deed of waiver executed between spouses in the middle of an otherwise intact marriage is not defective for want of notarisation or witnesses; it is something the Code does not allow at all. Couples reach for it in good faith more often than one might expect — usually to simplify a transaction, to reassure a lender, or to settle an argument — and the instrument does not do the work they think it does.

The two windows where a waiver is possible

The article names when it can be done: upon a judicial separation of property, or after the marriage has been dissolved or annulled. In both cases the form is prescribed — the waiver must appear in a public instrument and be recorded as the Code provides for marriage settlements. Notice what those two windows have in common. Each arrives at a point where the property regime is being wound up under judicial supervision and an accounting is being made, which is precisely when a spouse's decision to give something up can be seen by everyone with an interest in it, rather than agreed privately across a kitchen table.

Creditors can undo even a permitted waiver

Even a properly executed and recorded waiver is not beyond reach. The creditors of the spouse who made it may petition the court to rescind it, to the extent of the amount sufficient to cover their credits. The remedy is measured, not total: it unwinds only so much of the waiver as the debts require, leaving the rest standing. What this tells you about the provision as a whole is that it is aimed squarely at asset-shielding. A spouse cannot improve his position against his own creditors by giving his share to the other, whether during the marriage or on the way out of the regime.

What people are usually trying to achieve

Two motives account for most of these attempts. One is to protect the family home from a business or personal debt, and the article answers it directly through the rescission remedy. The other is to arrange a de facto separation without going to court, so that each spouse can deal with property independently. That one has a real route, but it runs through a petition rather than a deed: the Code provides for judicial separation of property, on stated causes or by joint petition, and it requires the couple's creditors to be listed and notified. If either motive is yours, that is the conversation to have with counsel.
