Ancestral property (from my mother side) was in court because of the my grand fathers brothers who filed a suit in court for partition during 2014-15 year. Now in year 2016-17 One of my mama(mothers own elder brother) got the ancestral property (my grand fathers share) under his name as Joint Property holder through court settlement. Recently in year 2018(Nov month) a partition deed is executed to the ancestral property of my mother side by my elder mama. My mother has 5 sisters (including my mother) and 4 brothers. But to my mother surprise she got only 8 gunta land in year 2018 Nov through partition deed. Remaining one of the sister also given with 8 gunta and other 3 sisters got 6 guntas only. Ancestral property has a total of around 250 guntas and my mother is saying partition is done fraduently as they didnot handed over any partition deed copy even though asked for, also she is expecting more property share now. Also my dad was not well during 2018 time and she was taking care of my dad and other family members in bangalore being away from native. , Now due to carona cowid time she got opportunity to visit the naive office and got the partition deed copy from sub registrar office. Now having this partition deed executed in Nov 2018 and now by 4.5 years of time is this partition deed can be challenged in court ? what is the procedure ? what is the pros and cons ? how much charges it may require to file suit and proceed with ? what all points can be made in the court from our side to cancel the partition deed and get success ? are daughters not eligible to get equal shares ? can some one give prior judgements given by high courts or supreme courts. in such scenarios ? any section of law of court can help us ?
