Short answer

Before trial begins, the court may allow an amendment necessary to decide the real controversy on just terms. After trial has commenced, the proviso is a threshold restriction: the court must conclude that, despite due diligence, the party could not have raised the matter earlier. Necessity, prejudice, bona fides and limitation remain relevant; amendment is not a right.

Step-by-step application

1. Identify the pleading. Order VI rule 1 defines “pleading” as plaint or written statement. Do not use rule 17 to amend evidence, an affidavit or an interlocutory application without identifying the proper procedural source.
2. Attach the proposed text. Present a clean proposed pleading and a marked comparison showing every insertion and deletion. Follow the court’s filing rules.
3. Explain necessity. State the real question in controversy the amendment enables the court to decide and why the existing pleading is insufficient.
4. Fix the trial-commencement position. Identify whether trial has commenced under the controlling authority for that proceeding. If it has, plead and prove the due-diligence facts required by the proviso rather than offering only a conclusion.
5. Address delay and prejudice. Explain when the new fact or basis became known, why it was unavailable earlier, whether further discovery or evidence will be needed, and whether costs and an opportunity to respond can fairly cure the prejudice.
6. Analyse limitation. State the limitation provision, accrual date and whether the amendment introduces a new cause of action or merely clarifies existing facts. Do not assume relation back; request any necessary direction about the amendment’s effective date and preserve the opponent’s limitation objection.
7. Seek consequential directions. Ask for time to file the amended pleading, consequential pleading, documents and any issue/evidence directions.
8. Comply with rule 18. If the order sets a time for amendment, amend within that period. Without a specified period, rule 18 uses fourteen days unless the court extends time.
