What rules apply if we chose separation of property as our marriage settlement regime?

What Article 143 sets up

Article 143 addresses couples who, before marrying, agreed in their marriage settlements to be governed by separation of property rather than the default regime. It states: should the future spouses agree in the marriage settlements that their property relations during marriage shall be governed by the regime of separation of property, the provisions of this Chapter shall be suppletory. The chapter referred to is the Family Code's own set of rules on the separation-of-property regime — the provisions immediately surrounding this article, which spell out how separately owned property is to be treated during the marriage.

"Suppletory" means the settlement comes first

The key word is suppletory: the chapter's rules do not override what the spouses agreed to in their marriage settlements. They apply only to fill gaps — questions the settlement itself does not address. If your settlement is silent on a particular point, the chapter's provisions step in to supply an answer; where your settlement does speak to a point, what you agreed to controls. This makes the marriage settlement the primary document to consult, with the chapter functioning as a backstop rather than a competing set of rules.

What this means for how you manage your property

Under this regime each spouse generally keeps ownership, administration, and enjoyment of their own separate property, since that is the entire point of choosing separation of property over a regime that pools assets. Article 143's role is narrower than describing all of that in detail — it simply establishes that the chapter's rules exist to support whatever the couple's own settlement provides, rather than to replace it. To know exactly how a specific asset or expense is meant to be handled, the marriage settlement itself is where that answer should be found first.

Why the settlement document matters more than people expect

Because the chapter is only a backup, a poorly drafted or vague marriage settlement can leave real gaps that the suppletory rules then have to fill, sometimes in ways neither spouse anticipated. If your settlement did not clearly address a particular kind of expense, debt, or asset, that silence is exactly the situation Article 143 is built for — the chapter's provisions step into that gap. Anyone relying on a separation-of-property arrangement should treat the settlement's actual wording, not general assumptions about the regime, as the starting point for any question about who owns or is responsible for what.
