Discovery Has a Clock, and It Starts Earlier Than You Think
In Texas state court, discovery is not an open-ended fishing expedition. From the day the lawsuit is filed, a clock starts running that controls how long you have to exchange information — and when it stops, it stops hard. Miss the cutoff and your key documents, your expert, or your best deposition may never see a courtroom.

First: Which Discovery Level Is Your Case In?
Every Texas case is assigned to one of three discovery levels under TRCP 190, and the level controls your deadlines and limits. Get this wrong and everything downstream is wrong.
- Level 1 (TRCP 190.2) — expedited actions under TRCP 169 (smaller monetary claims). Tight discovery period, tight per-side limits. Fast cases, short leash.
- Level 2 (TRCP 190.3) — the default. If your case is not Level 1 and the court has not ordered otherwise, you are here.
- Level 3 (TRCP 190.4) — a court-ordered, tailored plan. Common in complex cases: the judge (or the parties by agreement) sets custom periods and limits in a docket-control order.
If you do not know your level, ask — serving discovery beyond your level’s limits without leave draws objections you will lose.
The Level 2 Discovery Period (Where Most Cases Live)
Under TRCP 190.3, the discovery period begins when suit is filed and ends on the earlier of:
- 30 days before the date set for trial, or
- Nine months after the earlier of (a) the date of the first oral deposition, or (b) the due date of the first response to written discovery.
That second prong surprises people: your discovery period can close nine months after depositions start even if trial is a year away. Calendar both dates and watch the earlier one.
Level 2 also caps the tools: 50 hours of oral depositions per side and no more than 25 written interrogatories per party (each discrete subpart counts separately — draft carefully).
The 30-Day Response Rule (TRCP 194–197)
Almost every written discovery device in Texas runs on a 30-day response clock:
- Initial disclosures (TRCP 194): since the 2021 amendments, these are automatic — no request needed. Each party must disclose within 30 days after the first answer is filed: correct party names, potential parties, legal theories and factual bases, damage computations, witnesses, documents, insurance, and settlement agreements.
- Requests for production (TRCP 196): respond within 30 days after service. Exception: a defendant served with requests before its answer is due gets 50 days.
- Interrogatories (TRCP 197): 30 days after service, same 50-day exception for pre-answer defendants.
- Requests for admission (TRCP 198): 30 days — and this one bites hardest, because unanswered admissions are deemed admitted.
Note the asymmetry that traps newcomers: the plaintiff’s disclosure clock starts at the answer, but a defendant’s RFP clock can start even before it answers (with the 50-day cushion).
Worked Timeline: A Typical Level 2 Case
Suit filed January 5, 2026. Defendant answers February 9.
- By ~March 11: initial disclosures due (30 days after first answer).
- March 1: plaintiff serves requests for production → responses due March 31 (30 days).
- April 10: first oral deposition taken → the nine-month prong now runs to ~January 10, 2027.
- Trial set October 1, 2027 → 30-days-before-trial = September 1, 2027.
- Discovery cutoff: January 10, 2027 (the earlier of the two) — everything must be completed, not just served, by then.
The most common malpractice-adjacent mistake in Texas discovery: serving written discovery 30 days before the cutoff and assuming that is enough. It is not — responses must be due (and depositions taken) within the period.
Supplementation Is a Continuing Duty
Discovery responses are not fire-and-forget. If you learn your response is incomplete or incorrect, you must supplement. Trial judges have excluded witnesses and documents over supplementation failures — treat every response as a living document until the cutoff.
How This Differs From Federal Court
Federal discovery runs on the scheduling order’s cutoff (see our federal discovery cutoff guide) rather than TRCP 190’s automatic period. If your case gets removed to federal court mid-stream, your Texas deadlines die with the state case — recalculate everything under the federal scheduling order on day one.

FAQs
How long do I have to respond to discovery requests in Texas?
30 days after service for interrogatories, requests for production, and requests for admission. A defendant served before its answer is due gets 50 days.
When are initial disclosures due in Texas?
Within 30 days after the first answer is filed — automatic, no request needed (TRCP 194 as amended 2021).
What are the three discovery levels in Texas?
Level 1 (expedited/smaller cases, TRCP 190.2), Level 2 (the default, TRCP 190.3), and Level 3 (court-ordered custom plan, TRCP 190.4).
When does discovery close in a Texas Level 2 case?
The earlier of 30 days before trial or nine months after the first deposition (or first written-discovery response due date).
What happens if I miss a discovery deadline in Texas?
Consequences range from exclusion of evidence to deemed admissions (for requests for admission) to sanctions. Courts have little sympathy for blown discovery cutoffs.
Do I have to supplement my discovery responses?
Yes — supplementation is a continuing duty. If a response becomes incomplete or incorrect, you must correct it.
