When the original contract is concluded in writing, it is customary to include a term that states that any amendment or modification of this agreement must be made in writing and signed by all parties or their agents. You will find an example in the previous one: variation clause. Some written contracts go further and require parties to discuss and negotiate a proposed amendment only within a prescribed process and in a format agreed upon in advance, for example. B see Clause 10 and Schedule 12 of the previous: the outsourcing agreement – Lange Form. The tripartite agreement between the United Kingdom, India and Nepal was a treaty signed in 1947 on the rights of gurkhas recruited into the military service of the United Kingdom and India.  This agreement does not apply to gurkhas employed by the Nepalese army. As part of the agreement, 4 Gurkha regiments of the British Army were transferred to the British Army and 6 joined the Indian Army.  From 2020, India has 39 Gorkha battalions serving in 7 Gorkha regiments.  Those who were transferred to the British Army were sent to other remaining British colonies. In Malaya and Singapore, their presence was necessary in the Malaysian state of emergency and they had to replace the Sikh unit in Singapore, which was returning to the Indian army to gain Indian independence. These units of Malaya (Malaysia and Brunei) and Singapore, after the independence of these British colonies, are still part of the armed forces of Brunei and Singapore.
The agreement applies to the 3,500 Gurkhas who serve in the British Army and to nearly 40,000 Gurkhas in the Indian Army. It does not apply to the Gurkhas of the Nepalese Army. Any agreement to amend the contract is subject to general treaty principles and must be supported by a counterparty. If an attempt to amend the contract fails due to a lack of consideration or other formalities, it is still possible to implement the change by renouncing or changing contracts. See Practical Note: Variant of Contracts and Contract Variants – The checklist, which outlines the design considerations that must fuel the maintenance of different conditions for Gurkha soldiers, unlike their British counterparts, has been a source of friction in recent years, particularly with regard to old age pension.
