Munich Agreement
There most likely wasn't a declaration of independence; just a war to remove France. But if there was a document depicting such a "declaration..."; then the Geneva Agreement signed in 1954/55 (ending the 1st Indochina War/aka French Indochina War) was it.
A formal agreement between two or more nations is called a treaty.
A treaty is an agreement under international law between two or more sovereign states or international organizations. It's also known as an agreement, protocol, convention, or pact.
The Munich Agreement signed on 29 September 1938
