To be Effective:	December 20, 2001





TO
MORGAN STANLEY DEAN WITTER
INSURED MUNICIPAL BOND TRUST
DECLARATION OF TRUST
DATED
FEBRUARY 26, 1990


Amendment dated December 20, 2001 to the Declaration of
Trust
(the "Declaration") of Morgan Stanley Dean Witter Insured
Municipal Bond Trust
(the "Trust") dated February 26, 1990


	WHEREAS, the Trust was established by the Declaration
on the date hereinabove set forth under the laws of the
Commonwealth of Massachusetts; and

	WHEREAS, the Trustees of the Trust have deemed it
advisable to change the name of the Trust to "Morgan
Stanley Insured Municipal Bond Trust," such change to be
effective on December 20, 2001;

NOW, THEREFORE:

	1.  Section 1.1 of Article I of the Declaration is
hereby amended so that that Section shall read in its
entirety as follows:

"Section 1.1. Name.  The name of the Trust
created hereby is the Morgan Stanley Insured
Municipal Bond Trust and so far as may be
practicable the Trustees shall conduct the
Trust's activities, execute all documents and sue
or be sued under that name, which name (and the
word "Trust" whenever herein used) shall refer to
the Trustees as Trustees, and not as individuals,
or personally, and shall not refer to the
officers, agents, employees or Shareholders of
the Trust.  Should the Trustees determine that
the use of such name is not advisable, they may
use such other name for the Trust as they deem
proper and the Trust may hold its property and
conduct its activities under such other name."

	2.  Subsection (r) of Section 1.2 of Article I of the
Declaration is hereby amended so that that Subsection shall
read in its entirety as follows:

"Section 1.2. Definitions.

"(r)  "Trust" means the Morgan Stanley Insured
Municipal Bond Trust."

	3.  Section 10.7 of Article X of the Declaration is
hereby amended so that that Section shall read as follows:

"Section 10.7. Use of the name "Morgan Stanley."
Morgan Stanley Dean Witter & Co. ("MSDW") has
consented to the use by the Trust of the
identifying name "Morgan Stanley," which is a
property right of MSDW.  The Trust will only use
the name "Morgan Stanley" as a component of its
name and for no other purpose, and will not
purport to grant to any third party the right to
use the name "Morgan Stanley" for any purpose.
MSDW, or any corporate affiliate of MSDW, may use
or grant to others the right to use the name
"Morgan Stanley," or any combination or
abbreviation thereof, as all or a portion of a
corporate or business name or for any commercial
purpose, including a grant of such right to any
other investment company.  At the request of MSDW
or any corporate affiliate of MSDW, the Trust
will take such action as may be required to
provide its consent to the use of the name
"Morgan Stanley," or any combination or
abbreviation thereof, by MSDW or any corporate
affiliate of MSDW, or by any person to whom MSDW
or a corporate affiliate of MSDW shall have
granted the right to such use.  Upon the
termination of any investment advisory agreement
into which a corporate affiliate of MSDW and the
Trust may enter, the Trust shall, upon request of
MSDW or any corporate affiliate of MSDW, cease to
use the name "Morgan Stanley" as a component of
its name, and shall not use the name, or any
combination or abbreviation thereof, as part of
its name or for any other commercial purpose, and
shall cause its officers, Trustees and
Shareholders to take any and all actions which
MSDW or any corporate affiliate of MSDW may
request to effect the foregoing and to reconvey
to MSDW any and all rights to such name."

	4. The Trustees of the Trust hereby reaffirm the
Declaration, as amended, in all respects.

	5.  This Amendment may be executed in more than one
counterpart, each of which shall be deemed an original, but
all of which together shall constitute one and the same
document.







  IN WITNESS WHEREOF, the undersigned, the Trustees of the
Trust, have executed this instrument this 20th day of
December, 2001.
