Agricultural land hereditary for daughters in Rajasthan

The Land in question is in Keshorai Patan Distt. Bundi Rajasthan. Mr. Amichand ji purchased a land long back. He had 2 children Mr. Charan Singh and Ms Harbans Kaur. Mr. Charan Singh became the owner of the land after Mr. Amichand. Mr Charan Singh was alive till 1984. He also has 2 children Mr. Anil Kumar and Ms Gargi Bhutiyani. After Mr. Charan Singh the land was divided into 3 parts 1 for Anil Kumar, 1 For his wife Sita Devi and 1 for his daughter Gargi. Mr. Anil Kumar was alive till 2015. So after Mr. Anil Kumar his part of land is transferred to his wife Ms. Usha Mahajan. Now Ms. Harbans Kaur wants her share in the land and she is harassing the current land holders and not allowing them to take any profit out of the land. She has a powerful grand son who is a convicted felon. We need advice on this matter. Should we go to court and fight or should we settle with whatever they are offering. We are mentioned as cast Mahajan in all property papers.
