The amount of new civil litigation in Houston jumped 23% over the past five years.

Some practice areas like real property, motor vehicle and contract matters, saw double-digit gains from 2015 to 2019, while others like asbestos silica and other product liability cases saw major declines, according to data from the Texas Office of Court Administration.

Overall, there were 45,592 new civil cases filed in Harris County district courts in 2015, and the number increased to 55,985 in 2019, according to the data. The largest number came in 2018, when the county's district courts saw 61,440 new civil cases filed.

This means 2019's tally of nearly 56,000 represented a 9% drop from the previous year.

1.Real property is hot

But this 9% drop in civil litigation from 2018 to 2019 follows steady increases of 30% since 2014, according to Harris County District Courts Administrator Clay Bowman.

"Increases occurred over that period in all civil case types, but noticeably in real property cases," he wrote in an email.

The court data shows real property cases grew by 79% over the past five years, from 3,845 in 2015 to 6,888 cases in 2019.

A major contributing factor: Hurricane Harvey hit Houston in August 2017, and caused devastating property damage.

The statistics show the impact: in 2017 there were 5,445 cases, while in 2018 there were 7,925, which is a 46% year-over-year increase. The numbers began to drop in 2019, with 6,888 real property cases.

The number of injury or damage cases involving motor vehicles has grown by 71% in Harris County within the five years, from 7,434 to 12,747 cases. Houston is not alone in this uptick.

Debt cases have also been on the rise across Texas, and Houston was no exception. The data shows that there were 4,508 debt cases in 2015, and the number rose to 6,246 five years later, which is a 39% increase.
