“Pravda Yaroslavichey” increased responsibility of a given community for killing knyaz’es soldiers, tiuns (“tiun”, a privileged servant of knyazs or boyars), starostas (“starosta”, a representative from the low-ranking administration of a knyaz), otroks (“otrok”, a low-ranking soldier in the army of a knyaz) and other servants on their own territory. “
Pravda Yaroslavichey” provided severe punishment for arson, deliberate cattle mutilation, and collective encroachment on rich people's property.
After the 1113 Riot in Kiev, an exorbitant interest law was introduced that limited financial operations of moneylenders.

The Pravda stabilized the system of feudal relations and social inequality.
During 11th-13th centuries it made new laws for the smerds (“smerd” – a feudal-dependent peasant), zakups (“zakup” - a feudal-dependent peasant, who could become free after paying off his “zakup”, a feudal loan), kholops (“kholop” – a feudal-dependent peasant, who could be killed or sold like a slave) etc.
The Vast Edition of Pravda contains special regulations regarding the status of zakups and kholops.
It also reflects the role of the court of knyaz’, by increasing and giving various forms of punishment and penalties.
It instituted fines that benifited the knyaz’ or his administration with diminished compensation to the victims.

In an attempt to abolish the  blood feud  (that was quite common at that time), the Pravda narrowed its “usage” and limited the number of avengers to the closest relatives of the dead.
If there were no avengers on the victim's side, the killer had to pay a fine (called “vyra”) in favour of the knyaz’ and partial compensation to the relatives of the victim (the killer's community had to help him pay his fine).
If a woman was killed, one would have to pay half of the regular fine (called “poluvir’ye”, half of “vyra”).
The Pravda also protected the health and honor of the free members of the feudal society and provided financial compensation for mutilation or insult by word or deed.
The Pravda had a comprehensive system of punishments and penalties for larceny in a city or countryside, deliberate damage to forests, hunting grounds or lands, trespassing etc.
It also regulated debt  between individuals and contained articles of liability and hereditary law.
The Pravda made use of witnesses,  oaths and of “ordaliy” (lat.
ordalium, or “ordeal” in English), a kind of a last-resort test used to prove defendant's innocence or guilt in legal proceedings.
The legal process also included testimony witnesses,  evidence, collecting or hot pursuit.
Investigators had to check for false accusations, as well.
These were the first steps towards forensic science.
