# Payment of Dividend in Proportion to Paid-up Amount — Section 51
## Core Rule
A company may pay dividend in proportion to the amount paid-up on each share — only if the Articles of Association authorise it.
## When Does This Arise?
This becomes relevant when not all equity shares are equally paid-up (some are fully paid, others partly paid).
## Board's Power
The Board of Directors may decide to pay dividend on a pro-rata basis based on paid-up amount, provided:
- The Articles permit it, AND
- The equity shares are not equally paid-up.
## Critical Exception — Preference Shares
In the case of preference shares, dividend is ALWAYS paid at a fixed rate — never pro-rata based on paid-up amount. Section 51 applies essentially to equity shares.
