Section 6219. Garnishee's statement

Within ten days after service upon a
  garnishee of an order of attachment, or within such shorter time as  the
  court may direct, the garnishee shall serve upon the sheriff a statement
  specifying  all  debts of the garnishee to the defendant, when the debts
  are due, all property in the possession or custody of the  garnishee  in
  which  the  defendant  has an interest, and the amounts and value of the
  debts and property specified.  If the garnishee has money belonging  to,
  or  is  indebted  to,  the  defendant  in  at  least  the  amount of the
  attachment, he may limit his statement to that fact.
