Exemption of ancestral property from liability

When custom is the rule of decision in regard to succession to immoveable property then, notwithstanding any custom to the contrary, ancestral immovable property in the hands of a subsequent holder whether male or female and if female whether she holds as a limited owner or full owner shall not be liable in the execution of a decree or order of a court relating to a debt incurred by any of his predecessors in interest: Provided that, when the debt has been expressly charged by way of mortgage on ancestral immovable property by a predecessor in interest, the court shall determine the liability of such land as if this section had not been passed : Provided further, and subject to the foregoing proviso, that, in respect of a debt incurred before the commencement of this Act, ancestral property in the hands of a subsequent holder may be liable, only if all the following conditions are satisfied :— First. That, before such liability is determined, the judgement-debtor shall be given sufficient opportunity to show cause against such liabilty. Second. That such liability was permitted by the rule of custom applicable to the judgement-debtor immediately before the commencement of this Act, and nothing in this section shall prevent the judgement debtor from proving the contrary. Third. That the decree-holder is able to show to the satisfaction of the court, that, at the time the debt was originally incurred, there was a subsisting judgement or order of a competent court, not in ex parte proceedings, holding that such a custom was applicable to the sub-tribe in the tahsil to which the judgement-debtor belongs. Fourth. That the judgement-debtor is not able to show to the satisfaction of the court, that, at the time the debt was originally incurred, there was a subsisting judgement or order of a competent court, not in ex parte proceedings, holding to the contrary and subsequent to the judgement relied upon by the decree-holder.
