Discovery

Definition: Discovery is the formal pretrial process under the Texas Rules of Civil Procedure through which each party to a lawsuit, whether a divorce or a personal injury case, obtains documents, sworn answers, and testimony from the other side before trial.

Also called: pretrial discovery, written discovery

What discovery means in Texas

Discovery is how the parties to a Texas lawsuit learn the facts before trial. The Texas Rules of Civil Procedure give each side the right to demand information from the other, and the court enforces those demands. Rule 192 sets the scope: any matter that is not privileged and is relevant to the case, even if it would not be admissible at trial.

Rule 190 sorts cases into discovery levels that control how many interrogatories and deposition hours each side gets. Most divorces and injury suits proceed under Level 2 unless the court signs a tailored Level 3 order.

How it works in practice

Discovery opens with required disclosures under Rule 194. Within 30 days after the first answer is filed, each party must hand over basic information without being asked: legal theories, people with knowledge, damages calculations, insurance agreements, and in family cases the financial documents listed in Rule 194.2(c). The tools that follow are requests for production (Rule 196), interrogatories (Rule 197), requests for admission (Rule 198), and depositions (Rule 199).

In a Travis County divorce, discovery means bank and brokerage statements, tax returns, business records, and a sworn inventory and appraisement of every asset and debt. In a car accident case, the injured person produces medical records and bills, wage records, and photographs, while the defendant produces the insurance policy and the driver’s statement. Each side then deposes the other party and key witnesses.

Why it matters in your case

Cases are won or lost on what discovery turns up. A spouse who omits an account from a sworn inventory faces sanctions and a worse property division. Discovery is also expensive and slow, which drives most cases toward mediation. We treat discovery responses as sworn testimony, because that is what a judge treats them as.

Example

Greg lists a credit union account on his inventory but not the brokerage account he opened two years earlier. His wife’s lawyer subpoenas the brokerage records, and the omission comes out at his deposition. At trial the judge awards the wife a larger share of the estate and orders Greg to pay her fees for the extra discovery.
