Family in 1987 was Father (F), Mother (M), Son (S) and Daughter (D).
Father Died in 1987 year (died intestate). After Fathers death, Father’s self-occupied property was transferred to Son in 1988 without sister concern. Son sold property due to lost his Govt job due to misappropriation of money, taking care of his mother & family and alienated the property in 1990 for legal necessity. Daughter was married before 1988. Mother (M) died 2008. Now Daughter (D) filed case for property.
In this case, is Son (S) can be considered as Karta?
If not as karta, can Son(S) alienate property due to legal necessity?
