As Bobbi Kristina Brown remains in a medically induced coma while her father and boyfriend publicly feud, the future of her vast estate remains at stake and involves a number of key players.

As this chart indicates, Whitney Houston‘s 21-year-old daughter is the sole heir to her mother’s estimated $20 million fortune.

That estate is held in a trust administered by several family members – not including her father, Bobby Brown, who can make decisions about her health but is not an executor of the trust. If Bobbi Kristina were to die, her boyfriend, Nick Gordon, would likely receive nothing if there is no will naming him as a beneficiary.

The key players? Bobbi Kristina’s aunt and uncle, who are co-executors of their niece’s trust and would likely decide what happens to the money.

After doctors attempted last week to remove Bobbi Kristina from her medically induced coma, only to have her suffer violent seizures, she was quickly sedated back into a coma.

A family member told PEOPLE on Friday that Bobbi Kristina was still on a ventilator and has had no discernible change.
