When the object of the performance is the delivery of a thing or a sum of money and the obligee, without justification, fails to accept the performance tendered by the obligor, the tender, followed by deposit to the order of the court, produces all the effects of a performance from the time the tender was made if declared valid by the court.
A valid tender is an offer to perform according to the nature of the obligation.
