Mark Furey says John Morash will oversee the process and guide discussions for the town to become part of the Municipality of West Hants or the Municipality of the County of Kings.
The merger is expected to take effect April 15.
Hantsport is among several Nova Scotia towns that have voted to dissolve their municipal status due to financial difficulties over the past year.
Hantsport Mayor Rob Zwicker says he's confident Morash's experience guiding a similar merger in the past will assist his town.
Morash co-ordinated the amalgamation of Queens County with the Town of Liverpool from 1995 to 1996.
