Shah says that J&K, Junagadh and Hyderabad were the States which were left. But, for J&K, the circumstances were different. In the case of all other States, three documents were executed.

1. IOA - This means that you do not fully secede fully.

2. Standstill agreement - State of affairs are at a standstill.

3. Merger agreement - the State life comes to an end. It has fully merged with the Union.

In J&K, there was only IOA and no standstill agreement or merger agreement.
