Short answer. Possibly. Article 2155 of the Civil Code provides that payment by reason of a mistake in the construction or application of a doubtful or difficult question of law may be recovered as a payment made by mistake. A straightforward misreading of clear law likely does not qualify.
What the law says
Payment by reason of a mistake in the construction or application of a doubtful or difficult question of law may come within the scope of the preceding article.

The general rule and its exception for law mistakes
The ordinary rule is that ignorance of the law excuses no one — a person who pays because they misunderstood a clear legal rule generally cannot get their money back on that basis alone. Article 2155 creates a narrow exception: when the legal question involved was genuinely doubtful or difficult, and the payer misunderstood how to apply it, that payment may come within the rule on payments made through mistake. The emphasis on 'doubtful or difficult' is important — the article is not a general escape from all law-related payment errors.
What makes a question of law 'doubtful or difficult'
A doubtful or difficult legal question is one where even reasonable, informed people disagree about its meaning or application — provisions with conflicting interpretations, ambiguous statutory language, overlapping regulatory rules, or areas where the law was in flux at the time of the payment. If you paid because you misread a provision that is actually plain and settled, Article 2155 likely does not help you. But if the provision you misread was genuinely contested or hard to construe — even legal professionals disagreed about it — you have a stronger argument that the mistake was of the kind Article 2155 covers.
The link to solutio indebiti
Article 2155 works by incorporating payments made through legal mistake into the framework for recovering payments made without cause — the principle sometimes called solutio indebiti. The logic is the same: if you paid something you were not actually obligated to pay, and the payment was caused by a mistake (whether of fact or, under certain conditions, of law), unjust enrichment would result if the recipient were allowed to keep it. Article 2155 extends that recovery right to honest mistakes about doubtful legal questions, provided the other conditions for recovery are also met.
Evaluating whether your situation qualifies
The key fact question is whether the legal provision you misread was genuinely doubtful or difficult at the time you paid. If the provision was straightforward and the error was yours alone, recovery under Article 2155 is unlikely. If the provision was ambiguous, recently changed, or the subject of genuine interpretive uncertainty, the argument for recovery is stronger. Evidence that others also misread the same provision — or that legal authorities themselves gave conflicting guidance on it — can support the claim that the question was legitimately difficult. What you ultimately recover, and whether recovery is available at all, depends on the specific facts and the legal environment at the time of payment.
