Demand Letter (Letter Before Action / Mise en Demeure)

When to use this

A demand letter is the last formal step before litigation or arbitration. It creates a paper trail, establishes a record that the other party was given an opportunity to comply, and in several jurisdictions is a legal prerequisite to commencing certain court actions.

Use this skill when:

• A party has not paid an invoice, debt, or contractual sum and informal requests have failed.
• A party is in breach of contract (non-performance, defective performance, delay) and you want to trigger a cure period and preserve rights.
• An IP infringement has been identified and you want to demand cessation before filing.
• A regulatory complaint, arbitration, or court filing is intended and you need a pre-filing record.
• A personal-injury or tort claim requires pre-suit demand.

When this is not enough: some jurisdictions (UAE notarized demand, Lebanese mise en demeure via bailiff) require specific service formalities for the demand to start a statutory period running. Confirm service requirements before drafting.
