Has woman-empowerment contributed in increasing divorce rate and false dowry cases in India?

Yes, unfortunately this is a reason.

The Protection of Women from Domestic Violence Act 2005, which came into force in 2006, has given women a legitimate ground for divorce they did not have before. But, like any law, it can be misused. During 2005-2010, family courts would provide interim relief immediately. But now, with a majority of divorces cases adding domestic violence, it has become so common that the court thinks twice before granting them interim relief. Now, both men and women don’t have tolerance which leads to immediate breakup of the family.

Women know their rights and demand them too
 Officials from forums such as the Women's Commission, Family Courts and counselling centres are of the opinion that unlike in the past, women are increasingly aware of their rights today, while the men are not. This means they don't tolerate anything that they don't have to, anymore, and are seeking legal aid when needed. We have also noticed that often, many men still think that they can get away with mistreatment within the four walls of a house. This is one of the most common reasons for divorce."
