Short answer. Yes. Article 2259 states that a married woman's capacity to execute acts and contracts is governed by the Civil Code even if her marriage was celebrated under the former laws. The date of your marriage does not exempt you from the current rules on capacity.
What the law says
The capacity of a married woman to execute acts and contracts is governed by this Code, even if her marriage was celebrated under the former laws.

The new Code applies regardless of when you married
Article 2259 answers your question directly: "the capacity of a married woman to execute acts and contracts is governed by this Code, even if her marriage was celebrated under the former laws." The moment your marriage was celebrated does not freeze your legal capacity under whatever rules existed at that time. Instead, your capacity to act — to sign contracts, manage property, and conduct your own legal affairs — is measured against the Civil Code currently in force.
Why this transitional rule exists
This article belongs to the Civil Code's transitional provisions, written to answer exactly the kind of question people asked when the Code took effect: whose rights change, and whose do not, when a marriage predates the new law. For a married woman's capacity specifically, the legislature chose to apply the new rules immediately and universally, rather than leaving some women bound by the older framework simply because their wedding happened earlier. This avoided a patchwork where capacity depended on a marriage date rather than on the law actually in force.
What this means for contracts and property acts you undertake now
Because your capacity is governed by the current Code, any contract you sign, any property you manage, or any legal act you undertake today is evaluated under today's rules on a married woman's capacity, not under whatever more restrictive framework may have applied under the former laws at the time you married. If a contract or transaction you are entering into now is being questioned on the theory that older, more limiting rules should apply because of when you married, Article 2259 is the direct answer to that argument.
A word of caution on related but separate questions
This article addresses capacity to act — your ability to validly enter into contracts and manage affairs — and should not be confused with questions about your property regime with your husband, which depend on separate rules that may themselves have their own transitional provisions. Capacity and property regime are related but distinct legal questions, and resolving one does not automatically resolve the other. Anyone relying on an old restriction on a married woman's capacity to challenge a transaction should recognize that Article 2259 has already displaced that older rule.
