Short answer. Yes. Article 109 of the Family Code lists as exclusive property of each spouse that which is purchased with exclusive money of the wife or of the husband — even if bought during the marriage. The real battle is proving the money was exclusive, because the purchase happened while the partnership was running.

The four classes of exclusive property

Article 109 draws the map for spouses under the conjugal partnership of gains. Exclusive property of each spouse is: That which is brought to the marriage as his or her own; That which each acquires during the marriage by gratuitous title — inheritances and donations; That which is acquired by right of redemption, by barter or by exchange with property belonging to only one of the spouses; and That which is purchased with exclusive money of the wife or of the husband. Notice that three of the four classes can operate mid-marriage: the partnership does not swallow everything acquired after the wedding.

The money's source controls, not the date of purchase

For a purchase, the article looks at the money, not the calendar. Property bought during the marriage is exclusive when it is purchased with exclusive money of the buying spouse — money that is itself separate, such as funds brought into the marriage or received by inheritance or donation. The classes reinforce one another: exclusive money spent on a purchase produces exclusive property, just as exclusive property exchanged or bartered produces exclusive property. What the article protects, in each variation, is the separate character of value that never belonged to the partnership.

The battle is proof

Because the purchase happens while the partnership is running, the law's working assumption leans toward the partnership — property acquired during the marriage is generally presumed conjugal unless the contrary is proved — so the spouse claiming exclusivity carries the burden of tracing. That means showing the money's separate origin and its path into the purchase: the inheritance or donation documents, the account the funds sat in, the payments drawn from it, and ideally a deed that records the source. Exclusive funds mixed indistinguishably with conjugal income are the classic way an exclusive claim dies.

Why classification matters

Whether an asset is exclusive or conjugal drives who controls it, what happens to it when the partnership is liquidated, and what answers for whose obligations. If you bought property with money you believe was yours alone, assemble the paper trail now, while accounts and records are still retrievable — and have a lawyer review how the deed, the funding and the timing fit the article before a dispute forces the question.
