Written Procedure - UNCITRAL Arbitration

The written procedure usually consists of an exchange of a statement of claim and a statement of defense. The parties may agree on the number and sequence of written pleadings and the time limits for their submission. Unless otherwise provided, the respondent may also file a counterclaim.

The Tribunal may also order, or the parties may agree to file, further submissions such as a reply and rejoinder. 

Pleadings generally consist of statements of facts, legal submissions and the request for relief. They are accompanied by relevant evidence, in particular witness statements, expert reports and exhibits. 

Parties may amend or supplement their written submissions at any time unless the Tribunal considers it inappropriate in the circumstances.
