Chapter 4 covers Admission of a Partner — one of the densest and most heavily examined chapters in CBSE Class 12 Accountancy. Under Section 31 of the Indian Partnership Act, 1932, a new partner can be admitted only with the consent of all existing partners. Admission triggers a reconstitution of the firm: the old partnership ends, a new partnership begins, and several adjustments must flow through the books before the new partner takes his share of future profits.
The chapter develops, in order: (i) computation of the new profit-sharing ratio (with cases for surrender of equal shares, surrender of specific fractions, new ratio expressly stated, or share taken from a single old partner), (ii) the sacrificing ratio = Old − New, (iii) treatment of premium for goodwill brought in by the new partner — credited to old partners in sacrificing ratio, with separate entries for cash brought, cash withdrawn, premium not brought, and premium part-brought, (iv) hidden goodwill when the deed is silent, (v) the Revaluation A/c for changes in asset and liability values (profit/loss to OLD partners in OLD ratio), (vi) distribution of accumulated profits, losses, and reserves, (vii) special treatment of WCR and IFF, and (viii) capital adjustment to the new ratio.
The cornerstone rule throughout is AS 26 — self-generated goodwill cannot be raised in the books. All goodwill adjustments are routed through partners' Capital A/cs. Mastery of this chapter unlocks the parallel logic in Ch 5 (Retirement) and Ch 6 (Death), where the same patterns repeat with sacrifice replaced by gain.
