How should a partnership deed be amended?

Correct answer: With consent of partners

A partnership deed expresses the contractual understanding among the partners, so a change in its terms normally requires the consent of all partners, unless the existing agreement or applicable law provides a specific valid procedure. The amendment should be recorded clearly, preferably in writing, so that changes in capital, profit sharing, remuneration, authority, or other obligations can be proved and followed in the accounts. Option A is correct because customers and banks are not parties who ordinarily control the internal partnership agreement. An undisclosed change could create disputes and make accounting treatment uncertain.
