                     TYLER TECHNOLOGIES REPORTS 54% INCREASE
                      IN NET INCOME FOR SECOND QUARTER 2003

   BOARD APPOINTS JOHN MARR, JR. TO CHIEF OPERATING OFFICER POST AND INCREASES
              SHARE REPURCHASE AUTHORIZATION BY ONE MILLION SHARES


DALLAS, JULY 31, 2003 -- Dallas-based Tyler Technologies, Inc. (NYSE: TYL) today
reported that net income for the quarter ended June 30, 2003 increased 54% over
the same quarter of 2002, fueled by a 28% increase in software-related revenues.

Tyler also announced that its Board has appointed John Marr, Jr. to the newly
created position of Chief Operating Officer of the Company and has increased the
Company's common stock repurchase authorization by one million shares.

Net income for the three months ended June 30, 2003 was $2.0 million, or $0.04
per diluted share. Net income for the quarter ended June 30, 2002 was $1.3
million, or $0.03 per share.

Total revenues for the quarter ended June 30, 2003 increased 8% to $36.1 million
from $33.6 million in the quarter ended June 30, 2002. Software-related revenues
(software licenses, software services and maintenance) grew in the aggregate 28%
for the quarter, while appraisal services revenues declined 33% following the
completion of the initial three-year reassessment contract with Nassau County,
New York.

Operating income for the quarter ended June 30, 2003 was $3.1 million, an
increase of 35%, compared with operating income of $2.3 million in the same
quarter of 2002.

For the second quarter of 2003, EBITDA, or earnings before interest, income
taxes, depreciation and amortization, amounted to $5.2 million, or $0.12 per
share. EBITDA for the second quarter of 2002 amounted to $4.2 million, or $0.08
per share.

Net income for the six months ended June 30, 2003 amounted to $19.3 million, or
$0.42 per diluted share. Included in net income for the first half of 2003 is a
gross realized gain of $23.2 million ($16.2 million, or $0.35 per share, after
income taxes) in connection with the cash sale of Tyler's entire investment in
H.T.E., Inc. (HTE) during the first quarter of 2003. Net income for the six
months ended June 30, 2002 was $1.9 million, or $0.04 per share.

For the six months ended June 30, 2003, revenues increased 9% to $68.5 million
from $62.5 million in 2002. Operating income for the first half of 2003 was $4.8
million, an increase of 47% compared to $3.3 million in the first half of 2002.

EBITDA for the six months ended June 30, 2003 was $32.3 million, or $0.70 per
share (including $23.2 million, or $0.50 per share, relating to the gross
realized gain on the sale of Tyler's investment in HTE). EBITDA for the first
half of 2002 amounted to $7.2 million, or $0.14 per share.

Tyler ended the second quarter of 2003 with $27.5 million in cash and short-term
investments, and no debt. Free cash flow (cash provided by operating activities
minus capital expenditures) for the second quarter of 2003 was $3.5 million,
compared to $1.9 million in the second quarter of 2002.

During the second quarter, the Company successfully completed the repurchase of
5,107,000 shares of its common stock at a price of $4.00 per share under its
modified "Dutch auction" tender offer. Since August 16, 2002, the Company has
repurchased a total of 7,482,200 shares of its common stock at an average cash
cost of $3.99 per share. With the one million-share increase approved by Tyler's
Board on July 29, 2003, the Company is currently authorized to repurchase up to
an additional 2,017,800 shares of Tyler's common stock. The shares may be
repurchased from time to time in the open market or through negotiated
transactions. The amount and timing of purchases under the program will be
subject to, among other things, the price and availability of the Company's
shares and general market conditions. The repurchased shares may be reserved for
later reissue in connection with employee benefit plans and other general
corporate purposes.

"The second quarter was another very solid quarter for Tyler Technologies," said
John M. Yeaman, Tyler's President and Chief Executive Officer. "Our results show
that Tyler works - for our customers and for our shareholders. Once again, we
experienced strong growth in software-related revenues, which is indicative of
the strength of our position in the local government market and the
competitiveness of our products."

"Tyler's gross margin for the second quarter improved to 38.4% from 34.8% last
year, reflecting a positive shift in our revenue mix to a greater proportion of
high-margin software revenues," continued Mr. Yeaman. "Gross margin improvement
was most evident with respect to software services and maintenance, as a result
of greater efficiency in the utilization of our personnel and increased
operating leverage."

"The reduction in our appraisal services revenues was in line with anticipated
results following the completion of the initial three-year appraisal contract
with Nassau County. However, we were very successful in signing new appraisal
contracts in the first half of the year, including a $28 million, six-year
follow-on contract with Nassau County and a $9 million contract with Franklin
County, Ohio, and the long-term outlook for our appraisal business appears
encouraging."

 "During the second quarter we continued to sign new business at a very good
pace, and Tyler ended the quarter with a backlog of signed contracts at a record
high level of $131 million," added Mr. Yeaman. "Although the market,
particularly at the higher end, has clearly been impacted by the economy and
government budget pressures, we are encouraged by our ability to continue to
grow revenues and profits and gain market share during these uncertain times.
Our balance sheet continues to grow stronger and we believe that Tyler
Technologies is very well positioned to take advantage of emerging opportunities
as the overall economy strengthens."

Mr. Yeaman noted, "Our confidence in the outlook for 2003 continues to increase
and our view of the second half of the year remains positive. We continue to
expect that total revenues for 2003 will grow between 8% and 10% over 2002, with
solid growth in software-related revenues and a decrease in appraisal services
revenues. We now expect that fully diluted earnings per share for the year 2003
will be between $0.53 and $0.55 per share, including $0.36 from the gain on the
sale of our investment in HTE. EBITDA for 2003 is expected to be in the range of
$44 million to $46 million, including the $23 million gain on the sale of the
HTE investment. This guidance reflects the reduction in shares outstanding
following our stock repurchases in the first half of 2003."

The naming of John Marr, Jr. to the newly created position of Chief Operating
Officer of Tyler Technologies is part of a leadership succession plan
established by Tyler's Board of Directors. Mr. Marr is scheduled to succeed Mr.
Yeaman, 62, as Chief Executive Officer of Tyler in July 2004. At the same time,
Mr. Yeaman will become Chairman of Tyler's Board of Directors, while remaining
an officer of the Company. Mr. Marr's appointment as COO is effective
immediately, and he will continue to serve as President of Tyler's MUNIS
division and as a member of Tyler's Board of Directors and its Executive
Committee.

Mr. Yeaman commented, "I'm very pleased that John Marr will take on this
expanded role in Tyler's corporate management, and I look forward to continuing
to work closely with him during and after this transition period. John has
strong leadership skills, as well as many years of operational experience in the
local government software market, which I believe will be extremely valuable as
Tyler continues to grow."

Mr. Marr, 43, has 20 years of experience in the local government technology
industry. He joined MUNIS, Inc. in 1983 and was President of MUNIS when Tyler
acquired it in 1999. Since May 2002, Mr. Marr has also served on Tyler's Board
of Directors. Mr. Marr holds a bachelor's degree in accounting from the
University of Massachusetts.

Tyler also announced that Dustin Womble and Glenn Smith were appointed Executive
Vice Presidents of the Company. Both men will take on expanded roles at the
corporate level in addition to their current positions as leaders of Tyler
divisions. Mr. Womble, 44, is President of Tyler's INCODE division and Mr.
Smith, 50, is President of Tyler's Justice and Courts division and is a member
of Tyler's Board of Directors.

"Tyler is very fortunate to have a great deal of depth and experience throughout
our senior management team," continued Mr. Yeaman. "Their industry experience,
understanding of our customers' needs, and technical expertise have been major
factors in Tyler's growth and success over the past few years. Our operating
units are working well together and we have the management team in place to take
advantage of the tremendous opportunities in our business. By assuming the
additional responsibilities of these new corporate roles, I am certain that
John, Glenn and Dusty will make increasingly important contributions to Tyler's
future success."

(1)  Previously reported net revenues and cost of revenues were recast to
     reclassify as revenues certain expenses reimbursable from customers.

(2)  EBITDA consists of income before interest, income taxes, depreciation and
     amortization. Although EBITDA is not a calculation in accordance with
     accounting principles generally accepted in the United States (GAAP), we
     believe that EBITDA is widely used as a measure of operating performance.
     Nevertheless, the measure should not be considered in isolation or as a
     substitute for operating income, cash flows from operating activities or
     any other measure for determining operating activities or any other measure
     for determining operating performance or liquidity that is calculated in
     accordance with GAAP. In addition, since all companies do not calculate
     EBITDA in the same manner, this measure may not be comparable to similarly
     titled measures reported by other companies. The following reconciles
     EBITDA to net income for the periods presented.
