Partnership: Death, Insanity, or Unconsciousness of a Partner

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 2167

If one of the partners of a permission-based partnership dies or becomes insane or unconscious, the other partners cannot have disposal over the property. The same applies if one of them becomes foolish with finances, i.e. he spends his wealth in futile ways.
