Quorum Master
Quorum calculator for general assemblies under the Belgian Code of Companies and Associations (CSA/WVV).
What Is Quorum Master?
Quorum Master is a calculator that tells you whether your general assembly (GA) or board of directors can validly make decisions. Under Belgian law, a minimum number of members must be present (the "quorum") for votes to be valid.
Legal basis — Code of Companies and Associations (CSA; WVV in Dutch), Book 9 — Articles 9:13 (ordinary GA), 9:14 (extraordinary GA), and 9:21 (board of directors). These rules apply to all Belgian nonprofits since 1 May 2019.
Key Definitions
- Quorum: the minimum number of members who must be present for the assembly to make valid decisions.
- Majority: the percentage of "yes" votes needed for a decision to pass.
- Ordinary GA: the annual general assembly where you approve the accounts, budget, etc.
- Extraordinary GA: a special assembly convened to amend the bylaws (the "rules" of the nonprofit).
- Full (voting) members: members who have the right to vote at the GA (as opposed to associate or honorary members).

Belgian Rules Applied
The calculator automatically applies the rules of the CSA/WVV:
| Assembly type | Quorum (minimum attendance) | Majority to vote | CSA Article |
|---|---|---|---|
| Ordinary GA | 50% + 1 of full (voting) members | Simple majority (50% + 1 of votes) | Art. 9:13 |
| Extraordinary GA (amendment of bylaws) | 2/3 of full (voting) members | 4/5 of votes | Art. 9:14 |
| Dissolution | 2/3 of full (voting) members | 4/5 of votes | Art. 9:14 |
Second convocation — If the quorum is not reached at the first GA, the CSA allows you to convene a second assembly that can deliberate regardless of the number of members present (Art. 9:13, par. 2). Quorum Master notifies you of this option.
Quorum Master is available for free on the Starter plan.
