Short answer. No. Under Article 1850, a general partner has no authority to confess a judgment against the partnership without the written consent or ratification of that specific act by all the limited partners. Acting alone on this is outside his powers, so the limited partners' agreement is essential.
What the law says
without the written consent or ratification of the specific act by all the limited partners, a general partner or all of the general partners have no authority to: (1) Do any act in contravention of the certificate; (2) Do any act which would make it impossible to carry on the ordinary business of the partnership; (3) Confess a judgment against the partnership

A general partner's wide powers have limits
In a limited partnership the general partner runs the business, and Article 1850 begins by giving him broad authority: he shall have all the rights and powers and be subject to all the restrictions and liabilities of a partner in a partnership without limited partners. But that authority is fenced in. The same article lists specific acts he cannot do on his own. Confessing a judgment against the partnership is one of them. A confession of judgment is a formal admission that hands the other side a court judgment against the firm without a real fight, so it can expose the partnership to liability instantly. The law treats it as far too serious for one general partner to decide alone.
Unanimous written consent of the limited partners
The safeguard is precise. Article 1850 says that without the written consent or ratification of the specific act by all the limited partners, a general partner has no authority to confess a judgment against the partnership. Two points matter. First, the consent must be written and cover the specific act — a vague, general go-ahead is not enough; the limited partners must agree to this particular confession of judgment. Second, it must come from all the limited partners, not a majority. Consent can be given beforehand or the act can be ratified afterward, but until every limited partner has agreed in writing, the general partner simply lacks the power to bind the firm this way.
Why limited partners get this protection
Limited partners invest money but, as a rule, stay out of management to keep their liability limited. That trade-off would mean little if a general partner could unilaterally surrender to a judgment and endanger the firm's assets — and with them the limited partners' contributions. So Article 1850 groups confessing a judgment with other grave acts equally locked behind unanimous written consent: acting against the certificate, making it impossible to carry on the ordinary business, and admitting new partners. If a general partner confesses a judgment without that consent, he has acted beyond his authority, and the limited partners have solid ground to challenge it as unauthorized.
