# Calls on Shares — Sections 49 to 51
## Concept of a 'call'
A call is a demand by the company on shareholders to pay the unpaid balance on partly paid-up shares. The shareholder's statutory liability to pay the full amount is enforced by making calls.
### Key statutory backing
- Section 10(2): All money payable by any member to the company under MOA/AOA is a debt due from him.
- However, liability crystallises only when a valid call is made.
## Section 49 — Calls on shares of same class must be made on uniform basis
### Rule of uniformity
1. Calls shall be made on a uniform basis on all shares falling under the same class.
2. Usually, shares with the same nominal value are of the same class.
3. Exception: Shares of the same nominal value on which different sums have been paid shall NOT be deemed to fall under the same class for the purposes of Section 49.
## How calls fit with related provisions
| Section | Topic |
|---|---|
| Section 49 | Calls on uniform basis — same class |
| Section 50 | Calls in advance — accept/refuse; no voting rights on advance |
| Section 51 | Payment of dividends in proportion to paid-up amount (where authorised) |
## Step-by-step procedure for a valid call
1. Board resolution authorising the call (per AOA).
2. Notice to all shareholders of the same class — uniformly fixing call amount, due date, place.
3. Recording in the register of members.
4. On default — interest, forfeiture, lien (as per AOA), subject to Act.
## Why 'uniformity' matters
Uniformity ensures equality of treatment within a class. Without it, the Board could discriminate among shareholders of the same class — inviting capital-market mistrust and breach of equality principle in company law.
