EXPLANATION / SCOPE

Derivative title requires proof of the grantor’s title. The plaintiff must trace title back to a valid original owner. The principle applies the maxim nemo dat quod non habet. Long possession cannot substitute for proof of the grantor’s title. The rule applies to all claims based on purchase or grant. The court will examine the chain of title. The plaintiff cannot rely on the weakness of the defence. The principle protects against invalid transfers. The burden is on the plaintiff to prove the entire chain.
