"We need to be able to talk to the other facility to understand what it is they are capable of doing," Cynthia Chiarappa, a hospital spokeswoman, said Sunday.
The hospital also said it would need to confirm there is "lawful transportation" included in any plan to transfer Jahi, and written permission from the coroner.
"This is not transferring an individual in a vegetative state, but a dead body."
Dolan did not return multiple messages seeking comment on Sunday, but said previously that the family views the New York site as it's "last, last hope."
Jahi underwent a tonsillectomy at the hospital on Dec. 9 to treat sleep apnea. After she awoke from the operation, her family said, she started bleeding heavily from her mouth and went into cardiac arrest.
