Short answer. No. Unless your marriage settlements expressly provided for it, separation of property during the marriage takes place only by judicial order. A private agreement to divide what you own — however formal, however notarised — does not change the regime, and the property stays where the law puts it.
What the law says
In the absence of an express declaration in the marriage settlements, the separation of property between spouses during the marriage shall not take place except by judicial order. Such judicial separation of property may either be voluntary or for sufficient cause.

The rule and its single exception
Article 134 is short and firm: in the absence of an express declaration in the marriage settlements, the separation of property between spouses during the marriage shall not take place except by judicial order. There are only two lawful routes to separate property, and both are decided before the dispute. Either the spouses declared it expressly in a marriage settlement executed before the wedding, or a court orders it during the marriage. Nothing done privately in between counts, and the reason is that the property regime is not purely the couple's business — creditors and children have interests in it too.
What a private deed of separation actually achieves
Couples sign these often, usually when they separate in fact and want the question settled. The document does not do what they think. The regime continues, so a salary earned after signing is still partnership or community property, property bought after signing still falls into the mass, and a creditor of one spouse is not bound by an arrangement he was never told about. At most the agreement records what the spouses intended, which may matter later in a proper liquidation — but it does not itself divide anything. Nor does it protect either spouse from the other's creditors, which is often the very thing it was signed to do.
The judicial route is not necessarily a fight
The article adds that such judicial separation of property may either be voluntary or for sufficient cause, which is the part people miss. Spouses who agree can file a joint verified petition and ask the court to dissolve the regime and separate their common properties; the court's role there is to protect creditors and others with a pecuniary interest, not to referee a quarrel. Where one spouse is unwilling, the other must show one of the causes the Code lists — the point of the requirement is a court order, not a court battle.
Check the settlement first, then decide the route
Start with whether a marriage settlement exists and what it says, because an express declaration of separation of property in it means the regime was never community or partnership in the first place. If there is none, the question is which judicial route fits: a joint petition if both of you want it, or a petition on a sufficient cause if only one does. Either way, list the creditors honestly — the court is required to take measures to protect them, and a petition that hides debts is storing up a problem rather than solving one.
