1. All legacies, other than residuary ones or chattels, shall bear interest from twelve months after the date of the death of the testator at a rate equal to that allowed by law on money due upon order of the court. If the court finds that the legacies cannot be paid without jeopardizing the rights of interested parties because of litigation or other circumstances, the court shall determine what rate of interest, if any, not exceeding the rate allowed by law on money due upon order of the court, shall be allowed, after taking into consideration the income of the estate.

2. The yield on written instruments, shares of corporate stock and similar securities specifically devised shall be deemed a part of the legacy and shall be turned over to the legatee.
