The poem is trying to raise the issue of inheritance of daughters and mothers in the property of their father/husband. I think this issue is very important because after getting married, women are harassed for dowry and finally they are left by their husband. If inherited property would be with them, they can do enough to meet their ends.

Senior Superintendent of Police or Deputy Commissioner of Police are basically in charge of all the police stations in a district.

In my neighbourhood, there are many women who own property. They acquired in following ways:
(i) Some of the women have purchased the property themselves,
(ii) Some women's husbands registered properties in their name.
(iii) Some of the women inherited property from their father.

There are several reasons for which land records are compulsory. Suppose a farmer wants to buy a plot or field. Then, he needs to authenticate it. This can be done through the land records. If a farmer wants a loan from banks to dig a well in his land, he has to show the land records to prove that the land belongs to him. Moreover, these records are also essential for buying and selling of their properties. If the farmer wants to divide his property among his children, then the land records are essential.

When Mohan and his neighbours reached the police station, Mohan went to the person in-charge i.e. SHO and told him what had happened with him at the village. He also said that he wanted to give the complaint in writing. The SHO rudely brushed him aside saying that he could not be bothered to waste his time writing down minor complaints and then investigating them. Mohan showed him his injuries, but the SHO did not believe him. Mohan was puzzled and did not know what to do. He went and called his neighbours into the office. They argued strongly, then the case was registered.
