BOND REQUIREMENTS.

(a) Unless the personal representative of the estate is not required to give a general bond, a lease for which a cash consideration is required, although ordered, executed, and delivered, is not valid:

(1) unless the order authorizing the lease makes findings with respect to the general bond; and

(2) if the general bond has been found insufficient, unless and until:

(A) the bond has been increased or an additional bond given, as required by the order, with the sureties required by law; and

(B) the increased bond or additional bond has been approved by the judge and filed with the clerk of the court in which the proceedings are pending.

(b) If two or more leases of different land are authorized by the same order, the general bond must be increased, or additional bonds given, to cover all of the leases.
