We have an apartment, in one of the flat the husband and wife offen quarrel on major and minor issues.The voice of the quarrel is so loud that the residents in th apartment can not hear the voices of their own family members as well as can not hear tv and other vocal instrument. The wife always beat her husband declaring him as impotent and blame him for cheating about hiding his physical fault, he also uses bad words vise versa,this quarrel is continuing for 4 years. She also sacked her father in law who is 87 years old from the flat. The flat is in the name of father in law.He is living in his brother's flat with is brother
Now we also told the father in law and his son who is the husband of the wife to take legal action against her but they are lingering to take the action. Now I am the secretary of the builiding ,we all are fed up about this quarrel which breaks our peace of mind and common peace. What can I take the legal step for this?
