Dividends received from Bank

Aslm Mufti Saheb
Many years ago (+20 years), my mother received dividends from a Bank, which was used.
Those dividends were not huge sums of money however my mother wish to correct a wrong that was done, by using dividends froma bank(Interest)

How do we go about discharging of this interest monies received? the exact amount received is not known but probably less than a thousand rands
