Short answer. Yes, but only his interest. Under Article 1814, a judgment creditor of a partner may apply to the court to charge the debtor partner's interest, and the court may appoint a receiver of his share of the profits. You reach his financial interest — not the firm's assets, and without dissolving the partnership.

The charging order
Article 1814 gives a partner's personal creditor a specific, limited route to the partner's stake. On application to a competent court by any judgment creditor of a partner, the court may charge the interest of the debtor partner with payment of the unsatisfied amount of such judgment debt with interest thereon. This is a charging order. It fastens the creditor's claim onto the partner's interest in the partnership — his share of profits and surplus — so that money which would otherwise flow to the partner is redirected toward the judgment.
A receiver, and why not the assets
To make the charge effective, the article lets the court appoint a receiver of his share of the profits, and of any other money due or to fall due to him in respect of the partnership. The receiver collects what the partnership would pay the debtor partner and applies it to the judgment. The reason the law works this way — through the interest rather than the assets — is to protect the partnership and the other partners. Seizing the firm's specific property to pay one partner's personal debt would disrupt a business the other partners have a stake in, and the firm's own creditors have priority over its assets. So the personal creditor is confined to the debtor's slice of the value, reached without touching the going concern.
Redemption and no forced dissolution
The article also protects the debtor partner and the firm from losing more than the debt requires. The charged interest may be redeemed at any time before foreclosure — the debtor, or others on his behalf, can pay off the judgment and lift the charge. And if the court directs a sale of the charged interest, it may be bought by one or more of the partners, either with their own separate property or, with the consent of the uncharged partners, with partnership property — and importantly, such a purchase does not cause a dissolution. The partner also keeps whatever rights the exemption laws give him over his interest.
If you hold a judgment against a partner
If a partner owes you under a judgment and you want to reach his stake in a partnership, the route is to apply to a competent court for a charging order against his interest, and to ask for a receiver to collect his share of the profits and other money the firm owes him. Understand what you are getting: a claim on the debtor's financial interest, satisfied out of what the partnership pays him over time, not a right to the firm's assets or a place in the business.
