Kathmandu: Nepal’s inability to locate the original copy of the 1816 Treaty of Sugauli, a historic document that helped define its boundary with British India, has added a new layer to the country’s long-running border dispute with India. Nepal’s Foreign Minister Shisir Khanal told Parliament that the government could not confirm where the original treaty document is currently located.
The development has attracted attention because the treaty is closely linked to Nepal’s territorial claims in areas including Kalapani, Limpiyadhura and Lipulekh. The dispute has resurfaced in recent months, making the whereabouts and preservation of historical boundary records particularly significant.
What is the Treaty of Sugauli?
The Treaty of Sugauli was signed in 1816 between the East India Company and the Kingdom of Nepal following the Anglo-Nepalese War of 1814–16.
The agreement established important parts of the boundary between Nepal and territories controlled by British India. Under the treaty, Nepal ceded territories to the East India Company and accepted a boundary linked to the Kali River in the west.
The treaty remains historically important because differing interpretations of its provisions and subsequent maps and administrative records have contributed to the modern India-Nepal boundary dispute.
Nepal cannot confirm where the original is
Nepal’s Foreign Minister Shisir Khanal told Parliament that officials have been unable to establish whether the original copy of the 1816 treaty remains in the country’s archives.
The revelation does not necessarily mean that the treaty itself has disappeared from historical records. Copies, references and other archival material exist, and the agreement has been extensively documented.
However, the uncertainty surrounding Nepal’s original copy has raised questions about the country’s archival management and preservation of historically significant documents. (The Times of India)
Why the missing document matters now
The timing has made the development particularly sensitive.
India and Nepal continue to disagree over territories around Kalapani, Limpiyadhura and Lipulekh. Nepal has argued that its interpretation of the Kali River’s source supports its territorial claims, while India disputes that interpretation and points to historical administrative records and other evidence.

The 1816 treaty is therefore frequently cited in discussions about the western India-Nepal boundary.
The loss or uncertain whereabouts of an original archival document does not by itself change an international boundary. Nevertheless, such documents can be important when countries examine historical evidence during diplomatic negotiations.
The Kalapani-Lipulekh dispute
The most prominent part of the dispute concerns the area around Kalapani, Limpiyadhura and Lipulekh, near the India-Nepal-China trijunction.
Nepal maintains that the boundary should be determined using the Kali River’s source further to the northwest, near Limpiyadhura. India maintains a different interpretation of the river’s origin and the historical boundary.
The disagreement has continued for decades and became particularly prominent after Nepal published a revised political map in 2020 that included Kalapani, Lipulekh and Limpiyadhura within its territory.
India rejected the map and said Nepal’s claims were not based on historical facts or evidence.
Historical records remain central to the dispute
The boundary disagreement is not dependent on a single document.
Historical maps, survey records, administrative documents, agreements, correspondence and evidence relating to the river’s course have all featured in arguments surrounding the disputed territory.
An analysis by the Institute of South Asian Studies at the National University of Singapore noted that the roots of the boundary dispute lie in the Sugauli Treaty and its provisions concerning Nepal’s western boundary.
This makes the preservation and accessibility of historical records important for both sides.
Nepal’s wider border concerns
The India-Nepal border dispute has periodically become a politically sensitive issue inside Nepal.
The country shares a long open border with India, and the two neighbours have traditionally maintained close social, economic and cultural ties. However, territorial disagreements can generate strong nationalist reactions in both countries.
In 2026, renewed political discussion around the disputed areas has once again brought historical boundary documents into focus.
Missing does not mean the treaty is invalid
The disappearance or uncertain location of Nepal’s original copy should not be interpreted as automatically invalidating the 1816 treaty.
International agreements are not generally dependent on one surviving physical copy for their historical or legal existence. Other authenticated copies, official records and subsequent state practice can also be relevant.
The current issue is therefore primarily about archival preservation and historical evidence, rather than an immediate legal change to the India-Nepal boundary.
Questions over Nepal’s archives
The revelation has nevertheless prompted questions about how Nepal has preserved important state documents.
A treaty dating back more than two centuries is a major historical record. Its preservation would be expected to form part of the country’s national archival responsibilities.
Officials will now face questions about whether the original was misplaced, transferred to another archive, damaged, or remains in another government collection.
The government has yet to provide a definitive explanation for its whereabouts.
India and Nepal continue to rely on historical evidence
Both countries have previously used historical material to support their respective positions.
India has cited administrative records and maps dating back to the 19th century in support of its position over Kalapani. Nepal, meanwhile, has relied heavily on its interpretation of the Sugauli Treaty and the location of the Kali River’s source.
This means that the discovery of additional archival material — or confirmation of existing records — could remain significant in future diplomatic discussions.
A dispute that goes beyond one missing paper
The current controversy should therefore be viewed in the wider context of a longstanding territorial disagreement.
The Sugauli Treaty is one important piece of historical evidence, but the India-Nepal border question involves multiple records and competing interpretations accumulated over more than 200 years.
The treaty’s original copy being untraceable may generate political controversy, but it does not independently establish which country’s territorial interpretation is correct.
What happens next?
Nepal is likely to face pressure to clarify the status of the document and examine its archival holdings for any surviving original or authenticated copy.
If the original cannot be located, other historical copies and records could become even more important.
For India and Nepal, the broader challenge remains finding a diplomatic solution to disputed sections of their border while preserving the traditionally close relationship between the two countries.
Conclusion
Nepal’s inability to confirm the whereabouts of the original 1816 Treaty of Sugauli has sparked fresh interest because the historic agreement is closely connected to the disputed India-Nepal boundary.
The treaty remains an important historical reference in discussions over Kalapani, Limpiyadhura and Lipulekh, but the missing original does not by itself alter the existing border or settle the competing territorial claims.
As Nepal investigates its archives, the episode highlights the importance of preserving historical documents that continue to influence modern diplomatic and territorial disputes.
