Short answer. Yes, under the default rule. Article 91 of the Family Code includes in the absolute community of property all property the spouses owned at the time of marriage, not just what was acquired afterward — unless the law itself carves out an exception or the marriage settlement says otherwise.

What Article 91 actually says

Article 91 of the Family Code states the scope of the absolute community simply: all property owned by the spouses at the time of the celebration of the marriage, or acquired thereafter, forms part of the community — unless otherwise provided in the chapter or in the marriage settlements. The phrase "at the time of the celebration" is the operative one. It does not say "property bought together" or "property acquired after the wedding." If you owned it when you said your vows, it entered the community on that day.

The exceptions that can keep pre-marital property separate

The general rule yields to two things. First, specific provisions elsewhere in the same chapter of the Family Code can exclude certain property — for instance, property acquired before the marriage by a spouse who has legitimate children from a prior relationship is excluded, along with its fruits. Second, the spouses may execute a marriage settlement (also called a prenuptial agreement) before the wedding that adopts a different property regime or carves out specific assets. Without either of these, pre-marital property automatically joins the pool.

What this means in practice

If you owned a house, a vehicle, a savings account, or any other asset before the wedding and no exception applies, that asset is now community property. Both spouses have an equal interest in it. This becomes consequential in several situations: if one spouse wants to sell or mortgage the property, the other must consent; if the marriage ends, the property is included in the liquidation of the community; and if one spouse dies, the surviving spouse has a share in it alongside the heirs.

The role of marriage settlements

Spouses who want to keep pre-marital assets separate must execute a marriage settlement before the wedding. A post-wedding agreement cannot modify the property regime retroactively under ordinary circumstances. The settlement must be in a public instrument and registered. If no valid settlement was executed before marriage, the absolute community regime applies by operation of law — and with it, the rule that what you owned coming in now belongs to both of you.
