A heir is prohibited from inhering the property on the following occasions:
Murderer disqualified.—A person who commits murder or abets the commission of murder shall be disqualified from inheriting the property of the person murdered, or any other property in furtherance of the succession to which he or she committed or abetted the commission of the murder.
Convert’s descendants disqualified.—Where, before or after the commencement of this Act, a Hindu has ceased or ceases to be a Hindu by conversion to another religion, children born to him or her after such conversion and their descendants shall be disqualified from inheriting the property of any of their Hindu relatives, unless such children or descendants are Hindus at the time when the succession opens.
Succession when heir disqualified.—If any person is disqualified from inheriting any property under this Act, it shall devolve as if such person had died before the intestate.
Disease, defect, etc., not to disqualify.—No person shall be disqualified from succeeding to any property on the ground of any disease, defect or deformity, or save as provided in this Act, on any other ground whatsoever.
The above are certain grounds wherein a heir will be dis entitled to a share.
