Bobby Brown has officially filed for guardianship of his daughter Bobbi Kristina Brown's estate, including the $20 Million inheritance from her late mother Whitney Houston, according to NBC affiliate 11Alive.

This is the same house where Bobbi Kristina was found lying conscious in a bathtub. Brown was allegedly suffering from a drug overdose, and reportedly it was not a suicide attempt, according to Entertainment Tonight. Brown is now on a ventilator and in intensive care, after the doctors placed her in a medically induced coma for almost three months.

Speaking to Us Weekly, Brown's lawyer Christopher Brown of Brown & Rosen LLC said, "Bobbi Kristina's condition has changed since moving from Emory University Hospital and there has been improvement. Doctors have indicated that she will have a long life. However, Bobbi Kristina is presently embarking on a rehabilitation process and the quality of her life will not be known for years to come."

Her grandmother, Cissy Houston is in-charge of Bobbi Kristina's $20 million trust, apart from her aunt and uncle Pat Houston and Gary Houston.

Cissy Houston issued a public statement on Bobbi Kristina's health, last week saying, "I have just returned from visiting my granddaughter Bobbi Kristina in the hospital and while she is no longer in a medically induced coma, she has a tracheotomy and according to the doctors she has global and irreversible brain damage and remains unresponsive."

She also said, "Meeting with the doctors and understanding that she can live in this condition for a lifetime truly saddens me. We can only trust in God for a miracle at this time. Keep us in your prayers."

Her statement suggests that Bobby is still in a vegetative state and there is no hope of recovery any time soon.
