Re:  Hart Life Insurance Company Separate Account One
     Hart Life Insurance Company
     File Nos. 333-65507 and 811-09045 ("Registration Statement")
     Request for Withdrawal of Registration Statement

Ladies and Gentlemen:

Pursuant to Rule 477(a) under the Securities Act of 1933, as amended, Hart Life
Insurance Company ("Hart Life") and Hart Life Insurance Company Separate Account
One (the "Registrant") hereby request the withdrawal of their Registration
Statement on Form N-4 for the Individual Flexible Premium Variable Annuity
Contracts (the "Contracts"), initially filed with the Securities and Exchange
Commission on October 9, 1998 and any and all amendments and definitive filings
associated with it.

Hart Life and the Registrant are requesting withdrawal of the Registration
Statement for the Contracts because Hart Life has determined not to sell the
Contracts. Therefore, Hart Life and the Registrant hereby request that an order
be issued granting their request for withdrawal of the Registration Statement
for the Contracts as soon as is practicable. We have also filed a request on
Form N-8F to deregister Hart Life Insurance Company Separate Account One. No
Contracts were sold in connection with the Registration Statement.

If you have any questions concerning this filing, please do not hesitate to
contact me at (860) 843-5445.

Very truly yours,

/s/ Christopher M. Grinnell
Christopher M. Grinnell
Assistant Vice President
