# Calls on Shares — Sections 49 to 51
## 1. Concept of "Call"
A shareholder's liability to pay the full value of shares is enforced by way of "calls" on partly paid-up shares.
## 2. Statutory Liability — Section 10(2)
All money payable by any member under the MOA or AOA is a debt due to the company. However, this liability arises only when a valid call is made.
## 3. Structure of Sections 49–51
| Section | Subject |
|---|---|
| Section 49 | Calls shall be on a uniform basis |
| Section 50 | Calls in advance — company may accept; dividend on calls in advance per AOA; no voting rights on advance amount |
| Section 51 | Dividend in proportion to amount paid-up — only if AOA so permits |
## 4. Section 49 — Uniformity Principle
1. Calls shall be made on a uniform basis on all shares falling under the same class.
2. Same class generally means shares of the same nominal (face) value.
3. Important Distinction: Shares of the same nominal value on which different sums have been paid up shall NOT be deemed to fall in the same class for this purpose.
## 5. Why Uniformity?
Uniformity ensures equality of treatment among holders of the same class — no discriminatory calls (e.g., calling ₹10 from one holder and ₹5 from another holding the same class of share).
## 6. Key Takeaways
- A call is only valid if made by Board resolution and on uniform basis within the class.
- A call must be made on all members of that class — not selectively.
- Different classes can have different call amounts/timings.
- Within the same nominal value, if some shares already have more paid-up, they form a sub-class for this purpose.
