Item 8.01   Other Events.

On August 17, 2004 Century Properties Fund XX ("CPF") was sued, along with CPF's
managing  general  partner,  Fox  Capital  Management  Corporation,  and general
partner,  Fox  Partners  III.  The suit was brought in the Supreme  Court of the
State  of New  York,  New  York  County  by J.P.  Morgan  Trust  Company,  N.A.,
("Trustee")  formerly Chase  Manhattan  Bank & Trust  Company,  N.A., as Trustee
under the Trust  Indenture  dated as of February 22, 1984.  The Trustee  alleges
claims of breach of  contract,  money had and  received,  and unjust  enrichment
based on defendants'  alleged breaches of their  obligations under a Forbearance
Agreement dated as of November 3, 1999. The Trustee seeks the payment of certain
funds that it contends were  improperly  withheld or  misappropriated  under the
Forbearance Agreement.  In its breach of contract claim, the Trustee claims that
it is entitled to $541,776 plus interest,  which is comprised of management fees
paid to Fox Partners III and outstanding  reserves allegedly due to the Trustee.
CPF will  vigorously  defend the  litigation.  At this time it is  premature  to
determine whether the litigation will have a material adverse effect on CPF.
