We all know the immense contribution ancient Roman, medieval Roman (or Byzantine), and pre-modern HRE cannon law has made to the modern world. These empires relied on a  written constitution (or code) and trained magistrates, lawyers, and notaries [cf. Judith Herrin, Byzantium: The Surprising Life of a Medieval Empire; Peter H. Wilson, Europe's Tragedy: A New History of the Thirty Years War]. Much of today's European civil law can trace its origin to those cannons and much of our current legal framework (courts, judges, constitution, senate, and lawyers) are a direct copy of their ideas. 

I know that during the Mughal period, the administration was uniform and structured and that there existed courts (known as *kotwaalis*) and magistrates (or *kotwaals*) [cf, John Keay: India --A History].

I have four general questions:

1. Was there a (more or less) uniform law? 
2. Was this law (or these laws) documented? 
3. Were there lawyers? 
4. How effective were these courts? (less being outright civil violence and highly being close to the standards observed in the 15th century HRE)? 

And I ask these four general questions for each of the following three periods (thus in total 12 questions --let me know if you want to split them into different posts).

1. India from 6th century CE - 11th century CE (when it was divided amongst many smaller kingdoms for most times).
2. India from 11th century CE - 15th century CE (pre Mughal Islamic period in the North; divided rule in the South).
3. India from 16th century CE - 18th century CE (post Sher Shah Suri period --when the reforms started to the beginnings of the Company rule).
