International RelationsPublished 4 August 2026

The Line of Control (LoC) separates the areas of the former princely state of Jammu and Kashmir under Indian and Pakistani control. It reflects de facto military control, but it is not a mutually accepted international boundary determining final sovereignty.

Origin and governing framework

The LoC emerged from earlier ceasefire arrangements and received its present designation under the Simla Agreement, 1972, following the India-Pakistan conflict of 1971.

  • The Simla Agreement requires both countries to respect the LoC without prejudice to their respective legal positions.
  • Neither side may seek to alter the line unilaterally, irrespective of mutual differences or legal interpretations.
  • The LoC therefore regulates territorial control and military conduct without constituting a final settlement of the Jammu and Kashmir issue.

How it differs from an international boundary

An international boundary marks the legally accepted territorial limits of sovereign states. The LoC primarily identifies the extent of actual control exercised by India and Pakistan.

  • An international boundary has a de jure character, whereas the LoC principally has a de facto character.
  • A recognised boundary determines the ordinary territorial jurisdiction of neighbouring states; the LoC preserves competing claims rather than settling them.
  • An international boundary is intended to be permanent unless changed by agreement; the LoC remains subject to a mutually agreed final settlement.
  • Crossing the LoC occurs only through arrangements accepted by both governments and does not imply recognition of it as an international border.

Practical significance

Although it is not an international boundary, the LoC performs a boundary-like security function by separating armed forces and administrative control. Its observance is therefore central to ceasefire management, civilian security and stability in India-Pakistan relations.
