Quick answer: Yes — conversion is mandatory. Under the Law on Enterprises 2020 (amended by Law No. 76/2025/QH15, effective 01/7/2025), a multi-member limited liability company has a maximum of 50 members. When the 51st member joins (exceeding 50 members), the company no longer satisfies the member-number condition of this enterprise type and must convert to a suitable form — normally a joint stock company (no limit on the number of shareholders, minimum 03).
Legal basis
- Law on Enterprises 2020 (amended by Law No. 76/2025/QH15) — provisions on the number of members of a multi-member LLC (02–50) and conversion of enterprise types.
Why must the company convert?
- Multi-member LLC: from 02 to 50 members — this is the defining condition of the enterprise type;
- The 51st member → exceeds the maximum threshold → the company must convert its enterprise type (to a joint stock company) to continue existing lawfully;
- Failure to convert on time may result in administrative penalties in the field of enterprise registration.
Conversion procedure (overview)
- The Members’ Council approves the conversion plan (together with the charter of the joint stock company and the plan to convert contributed capital into shares);
- Prepare the dossier: enterprise registration application (for the joint stock company), charter, list of shareholders, conversion decision…;
- File the dossier at the provincial-level Business Registration Authority;
- Receive the new enterprise registration certificate for the joint stock company; the LLC ceases to exist in its old form and the new company inherits all rights and obligations.
Key notes
- Conversion does not terminate the company’s rights and obligations — the new joint stock company inherits all of them;
- Sub-licenses and contracts recording the old enterprise type should be reviewed and updated after conversion.
