When a notice helps
A notice creates a documented record, formally crystallises the demand, and often unlocks otherwise stuck conversations. It is most effective when the underlying contract and communication trail support it.
When it hurts
Premature notices can harden positions, end commercial conversations, and signal a willingness to litigate that you may not actually want.
