A claim may appear factually strong and still face a limitation problem.
Limitation law can affect when a proceeding must be initiated, and the answer may depend on the nature of the claim, the relevant statutory provision, acknowledgments, continuing causes of action and other facts.
The important point is practical: do not calculate limitation from memory.
When a dispute first arises, preserve the dates. Record when the agreement was made, when payment became due, when the breach occurred, when a demand was made and when relevant acknowledgments were given.
A legal consultation early in the dispute can identify whether time is already running and whether urgent action is required.
Delay can sometimes be explained. It should never be assumed to be harmless.
