Short answer. Yes, if you went beyond your rights as a limited partner and took part in controlling the business. Article 1848 of the Civil Code is clear: a limited partner who exercises control over business operations becomes personally liable as a general partner — with unlimited personal liability.
What the law says
A limited partner shall not become liable as a general partner unless, in addition to the exercise of his rights and powers as a limited partner, he takes part in the control of the business.

What the law says
Article 1848 draws a clear line: "A limited partner shall not become liable as a general partner unless, in addition to the exercise of his rights and powers as a limited partner, he takes part in the control of the business." Limited partners enjoy capped liability precisely because they are passive investors — they put in capital but do not run the firm. The moment a limited partner crosses into managing and controlling day-to-day decisions, the law treats them like a general partner, with all the unlimited personal liability that comes with that role.
Exercising your rights is not the problem
Article 1848 makes an important distinction. Simply exercising the rights and powers that belong to limited partners does not trigger liability. A limited partner is entitled to inspect books, receive financial reports, vote on certain fundamental changes, and share in profits. Doing those things — all of which are rights the law gives limited partners — does not transform you into a general partner. The law uses the phrase "in addition to" deliberately: it is the extra step of taking control that crosses the line, not the exercise of normal limited partner rights.
What counts as 'control of the business'
The Civil Code does not define 'control' with precision, but the concept involves making managerial decisions that belong to the general partners: hiring and firing key employees, directing business strategy, committing the partnership to contracts, managing the firm's day-to-day operations, or holding yourself out to third parties as having authority to bind the firm. The more a limited partner acts in ways that are indistinguishable from how a general partner behaves, the stronger the case that Article 1848 applies. Even occasional or informal involvement in control can be enough if it is real rather than ceremonial.
Practical consequences
If you have been participating in business control, your limited liability protection is at risk. Creditors who deal with the partnership can potentially pursue you personally for the firm's debts — up to the full amount, not just your investment. The exposure is not retroactive to the moment the partnership was formed; it arises from the period during which you exercised control. Going forward, the fix is to step back from control and limit your involvement to the rights the law actually gives limited partners. If you are unsure whether what you have been doing crosses into control, legal counsel can help you assess the exposure and restructure your role.
