I bought pidyon haben coins and gave the seller the first of five installments of a mutually agreed upon payment plan. ( The full amount will not have been paid at the time of the pidyon. )
Am I considered to be the "owner" as far as the halacha of owning the coins is concerned ?
Or must the full amount be paid prior to the pidyon ?
The pidyon is this Sunday 11-7-04, so please respond as soon as possible.
