Justin Bieber's monkey is set to become the property of Germany after the pop star missed the deadline to claim his pet.

The pop sensation's carpuchin Mally was seized by customs officials in Munich, Germany, on 28 March (13) after he failed to provide the required entry clearance documents for the primate.

Bieber was given until midnight local time on Friday (17May13) to produce Mally's vaccination and import papers, but a spokesperson for Munich's customs department tells Billboard.com officials received no word from the singer.

As a result, ownership will be transferred to Germany on Tuesday (21May13).

The Boyfriend hitmaker has six weeks to appeal against the decision.

Bieber is also facing a huge bill from bosses at the Munich animal sanctuary who have looked after Mally during his tour.
