Is the testimony of an heir concerning the property (mal) of the sick person admissible?

Primary text

There are two views regarding the acceptance of an heir's testimony about the property of a sick person. One view accepts the testimony because they are establishing the right to the property for the sick person; should the sick person die, the property transfers to them, resembling testimony given on behalf of a healthy person, unlike in cases of bodily harm where death necessitates blood money for the heir-witnesses. The second view rejects the testimony because establishing the property right for the sick person inherently attaches the rights of the heirs to it, evidenced by the rule that the sick person's voluntary disposition (tabarru') exceeding one-third of the estate is invalid.
