Section 391. Final orders conclusive; to be entered and docketed as a judgment

No final order or judgment  of  registration  shall  be  made,
  unless   the  court  is  satisfied  that  the  title  to  be  registered
  accordingly is free from reasonable doubt. The final order entered  upon
  an application for registration is deemed to be a final judgment and may
  be  entered  and docketed and enforced as a final judgment in an action.
  Before the final order can be docketed,  an  enrollment  must  be  filed
  thereupon  as  the  judgment  roll  in an action, as provided in section
  three hundred and ninety-three of this chapter.  The  judgment  and  any
  order  made  and entered in a proceeding under this act shall, except as
  herein otherwise provided, be forever binding and  conclusive  upon  the
  state  of  New  York and all persons in the world, whether mentioned and
  served with the said notice specifically by name,  or  included  in  the
  description,  "all  other  persons, if any, having any right or interest
  in, or liens upon, the property affected by this proceeding, or any part
  thereof." It shall not be an exception to such conclusiveness  that  any
  such  person is an infant, mentally ill or is under any other disability
  or is not yet in being.
