Re: Delaware Group Adviser Funds (the "Fund")
File Nos. 33-67490, 811-7972
Dear Sir or Madam:
Pursuant to Rule 497(j) under the Securities Act of 1933, as amended,
this letter serves as certification that the form of Supplements to the
Prospectuses and Statement of Additional Information, that would have been filed
under paragraph (c) of Rule 497 would not have differed from those contained in
Post-Effective Amendment Nos. 12/14 (the "Post Effective Amendment") to the
Registration Statement of Delaware Group Adviser Funds. The Post Effective
Amendment was filed with the Securities and Exchange Commission electronically
on November 22, 1999 and became effective on November 23, 1999.
Please direct any questions or comments relating to this certification
to me at the above phone number.
Very truly yours,
/s/ Michael P. O'Hare
