R. Kelly Reportedly Physically Abused Aaliyah

We are learning more about the relationship between R. Kelly and Aaliyah.
In Surviving R. Kelly we learned that they got married, the marriage was annulled and Aaliyah may have been pregnant by R.Kelly.
Now we are learning that there may have been physical abuse.
The marriage and the legal claim against him are sealed in Detroit but a Chicago reporter was able to get his hands on them.
In the document both sides signed non-disclosure agreements not to pursue legal claims for physical abuse.
Many have wondered why the family has never pursued legal action against R.Kelly. The NDA may explain why.
Aaliyah’s birthday is January 16th. She would have been 40 years old.
Should the family find a way around the non-disclosure agreement and pursue legal action against R.Kelly?
