Texas Discovery Deadlines: Rules and Response Dates

Legal content overseen by Nathan Walter, Esq., attorney licensed in California (State Bar No. 313299).

Texas discovery deadlines depend on the obligation and its trigger. In non-Family Code suits subject to initial disclosures, disclosures are due within 30 days after the first answer or general appearance is filed (Tex. R. Civ. P. 194.2(a)). Written responses to interrogatories, requests for production or requests for admission are due within 30 days after service (Rules 196.2(a), 197.2(a), 198.2(a)).

Court orders, agreements complying with Rule 11 and case-specific exceptions can change these defaults. This guide maps the deadlines, explains service and counting rules, and works through an invented example.

The discovery control plan also determines when discovery ends. Confirm current text on the Texas Judicial Branch rules page before using the table.

Texas discovery deadlines at a glance

This guide covers Texas state district and county-court civil discovery under the rules in the Texas Judicial Branch compilation. It does not cover justice-court or federal practice, or subpoenas. For broader workflows, see our overview of discovery responses and Briefpoint‘s defense firm solutions.

Unless a row says otherwise, the table describes suits not governed by the Family Code. These are defaults subject to applicable exemptions, court orders and permitted agreements (Rules 191.1, 194.1(a)).

Obligation	Default timing	Texas rule
Initial disclosures	30 days after the first answer or general appearance is filed; for a party served or joined later, 30 days after service or joinder	194.2(a)
Last day to serve requests	No later than 30 days before the end of the discovery period	196.1(a), 197.1, 198.1
Response to requests	30 days after service (50 days for a Family Code defendant served before its answer is due)	196.2(a), 197.2(a), 198.2(a)
Level 1 discovery period	Starts when the first initial disclosures are due; runs 180 days	190.2(b)(1)(A)
Level 2 discovery period	Starts when the first initial disclosures are due; ends at the earlier of 30 days before trial or nine months after they are due	190.3(b)(1)(A)
Experts for a party seeking affirmative relief	90 days before the end of the discovery period, unless the court orders otherwise	195.2(a)
All other experts	60 days before the end of the discovery period, unless the court orders otherwise	195.2(b)
Pretrial disclosures	At least 30 days before trial, unless the court orders otherwise	194.4(b)
Supplemental responses	Reasonably promptly; less than 30 days before trial is presumed not reasonably prompt, except as otherwise provided by the rules	193.5(b)

Rule 194.1(a) excludes Family Code suits from required disclosures. Rule 194.2(c) lists exempt proceedings, including habeas corpus petitions and appeals from justice court. The discovery-period rows run from the date disclosures are due, not served.

Which discovery level controls the clock?

Every Texas case must be governed by a discovery control plan, and the plaintiff must allege in the first numbered paragraph of the original petition whether discovery is intended to proceed under Level 1, 2 or 3 (Rule 190.1).

Level 1: expedited actions and qualifying divorces

Level 1 applies to suits governed by the expedited actions process in Rule 169 (Rule 190.2(a)(1)). That process applies when all claimants other than counter-claimants affirmatively plead that they seek only monetary relief aggregating $325,000 or less, excluding interest, statutory or punitive damages and penalties, and attorney fees and costs (Rule 169(a)). It also applies to a divorce without children in which a party pleads a marital estate worth more than zero but not more than $250,000, unless the parties agree Rule 190.3 applies or the court orders a Level 3 plan (Rule 190.2(a)(2)).

Outside the Family Code, the period begins when the first initial disclosures are due and continues for 180 days. In a Family Code suit it begins at filing and continues until 180 days after the first request for discovery of any kind is served on a party (Rule 190.2(b)(1)).

Level 2: the default plan

Level 2 applies unless a Level 1 or Level 3 plan governs (Rule 190.3(a)). Outside the Family Code, the period begins when the first initial disclosures are due and ends at the earlier of 30 days before the date set for trial or nine months after those disclosures are due (Rule 190.3(b)(1)(A)(i)–(ii)). In a Family Code suit the period runs from filing until 30 days before trial (Rule 190.3(b)(1)(B)).

Level 3: the court’s tailored plan

On a party’s motion the court must order a tailored plan, and it may do so on its own initiative. The parties may submit an agreed order (Rule 190.4(a)). The plan must include a trial date or a conference to set one, a discovery period, limits on discovery and deadlines for joining parties, amending pleadings and designating experts. The period may be one during which all discovery must be conducted or one during which all requests must be sent (Rule 190.4(b)). Level 1 or 2 limits continue unless the plan specifically changes them.

Request limits are separate from time limits

Discrete subparts count separately. Under Level 1, any party may serve on any other party no more than 15 interrogatories, 15 requests for production and 15 requests for admission (Rule 190.2(b)(3)–(5)). Under Level 2, any party may serve on any other party no more than 25 interrogatories (Rule 190.3(b)(3)). Both interrogatory limits exclude interrogatories asking a party only to identify or authenticate specific documents.

How service and time computation affect the date

Identify the effective service event

Rule 21a(b) says when service is complete:

• Mail or commercial delivery: on deposit, postpaid and properly addressed, in the mail or with the carrier (Rule 21a(b)(1)).
• Fax: on receipt, and service completed after 5:00 p.m. local time of the recipient is deemed served the next day (Rule 21a(b)(2)).
• Electronic service: on transmission to the serving party’s electronic filing service provider (Rule 21a(b)(3)).

The 5:00 p.m. rule appears only in the fax provision. Rule 21a(b)(3) does not mention ordinary email, so it should not be read as the completion rule for a message sent outside the electronic filing manager.

Count under Rule 4

Rule 4 excludes the day of the event that starts the period and includes the last day unless it is a Saturday, Sunday or legal holiday, in which case the period runs until the end of the next day that is not one. Weekends and holidays are not counted in periods of five days or less, except for the three-day extensions in Rules 21 and 21a. A 30-day period therefore counts weekends, which matter only if the last day lands on one.

Add only the applicable service extension

Rule 21a(c) adds three days when a party must act within a prescribed period after service of a paper and the paper is served by mail. It says nothing about fax, commercial delivery or electronic service, and it does not reach a period that runs from filing, such as Rule 194.2(a).

Written responses, objections and missed deadlines

Response timing for each request type

A party must respond to written discovery in writing within the time provided by court order or the rules (Rule 193.1). The default is 30 days after service for interrogatories (Rule 197.2(a)), requests for production (Rule 196.2(a)) and requests for admission (Rule 198.2(a)). Each rule has the same Family Code exception: a defendant served before its answer is due need not respond until 50 days after service.

In a suit not governed by the Family Code, unless the parties agree or the court orders otherwise, a party cannot serve discovery until after the other party’s initial disclosures are due (Rule 192.2(a)(1)). In a Family Code suit, a party may serve discovery with the initial pleading (Rule 192.2(a)(2)). Requests for production, interrogatories and requests for admission must be served no later than 30 days before the end of the discovery period, subject to permitted modifications (Rules 196.1(a), 197.1, 198.1, 191.1). Comment 4 to Rule 190 adds that, absent an order or agreement, requests must go out early enough for the response deadline to fall within the discovery period.

For device-specific drafting, see our guides on responding to interrogatories in Texas, responding to requests for production in Texas and responding to requests for admission in Texas.

Objections, privilege and verification

An objection must be in writing, made within the time for response, and state its legal or factual basis and the extent of the refusal (Rule 193.2(a)). An objection not made in time, or obscured by numerous unfounded objections, is waived unless the court excuses the waiver for good cause (Rule 193.2(e)). Our Texas discovery objections cheat sheet covers the objection grounds in detail.

Privilege runs separately. A party should not object on privilege grounds but should follow Rule 193.3, stating that material has been withheld, the request it relates to and the privilege asserted (Rules 193.2(f), 193.3(a)). A motion for a protective order may be made within the time permitted for response and does not waive an objection or privilege (Rule 192.6(a)).

Two signature rules apply. For a represented party, an attorney must sign every response and objection and include the attorney’s State Bar of Texas identification number and required contact information; an unrepresented party signs personally and includes the required contact information (Rule 191.3(a)).

The responding party, not an agent or attorney, must sign interrogatory answers under oath. When answers rely on information obtained from other persons, the party may say so; that provision does not dispense with the oath. A party need not sign answers to interrogatories about persons with knowledge of relevant facts, trial witnesses and legal contentions (Rule 197.2(d)(1)–(2)).

Consequences differ by request type

If a response to a request for admission is not timely served, the request is considered admitted without the necessity of a court order (Rule 198.2(c)). An admitted matter is conclusively established unless the court permits withdrawal or amendment on good cause, with findings that the parties relying on the admissions will not be unduly prejudiced and that the merits will be subserved (Rule 198.3).

For other discovery, a party that fails to make, amend or supplement a response in a timely manner may not introduce the undisclosed material or offer an untimely identified witness other than a named party. The exceptions are good cause or no unfair surprise or prejudice, and the party seeking to use the evidence carries the burden (Rule 193.6(a)–(b)).

Extensions, experts and supplementation

Changing a response date or the control plan

Discovery procedures and limits may be modified by agreement of the parties or by court order for good cause, except where specifically prohibited. An agreement is enforceable if it complies with Rule 11 (Rule 191.1). Comment 1 to the 1999 change to Rule 191 adds that parties cannot modify a court order by agreement alone. The court may modify a control plan at any time and must do so when the interest of justice requires (Rule 190.5).

Experts: count back from the end of discovery

Outside the Family Code, and unless the court orders otherwise, a party designates experts by furnishing the Rule 195.5(a) information 90 days before the end of the discovery period for experts testifying for a party seeking affirmative relief and 60 days before for all other experts (Rule 195.2). The wording turns on whether the party seeks affirmative relief, not on whether it is the plaintiff or defendant. Both dates count back from the end of discovery, not from trial. Rule 195.3(a)(1) also requires an extension for other experts on the same subject when its no-report and delayed-deposition conditions are met.

Supplement reasonably promptly

When a party learns that a written discovery response was incomplete or incorrect when made, or is no longer complete and correct, Rule 193.5(a) requires amendment or supplementation to the extent specified in that rule. The duty applies to discovery seeking the identification of persons with knowledge of relevant facts, trial witnesses or expert witnesses. For other information, it applies unless the additional or corrective information has already been made known to the other parties in writing, on the record at a deposition or through other discovery responses (Rule 193.5(a)(1)–(2)).

Except as otherwise provided by the rules, an amended or supplemental response made less than 30 days before trial is presumed not to have been made reasonably promptly (Rule 193.5(b)). The presumption does not make the 30th day before trial a safe date. Pretrial disclosures have their own deadline of at least 30 days before trial, unless the court orders otherwise (Rule 194.4(b)).

A worked defense-team timeline

This invented example illustrates the rule’s counting method, not a deadline for an actual case. Assume a suit not governed by the Family Code and not exempt from initial disclosures, with no agreement or order changing any period and no legal holiday on a day that matters.

1. Wednesday, April 1, 2026: the defendant files the first answer in the suit, with no earlier general appearance. The filing starts the initial-disclosure period under Rule 194.2(a).
2. Friday, May 1, 2026: Rule 4 excludes April 1. April 2 is day 1, April 30 is day 29 and May 1 is day 30. No Rule 21a(c) days are added, because the period runs from filing.
3. May 1 as the anchor: under Rule 190.2(b)(1)(A) or 190.3(b)(1)(A), the discovery period begins when the first initial disclosures are due, whatever date they were sent. The end date depends on a plan and trial date the example does not supply.
4. Friday, May 15, 2026: the plaintiff serves requests for admission through the electronic filing manager, after the disclosures were due as Rule 192.2(a)(1) requires. Under Rule 21a(b)(3), service is complete on transmission to the provider.
5. Counting the response: Rule 4 excludes May 15. May 16 is day 1, May 31 is day 16, June 1 is day 17 and June 14 is day 30. June 14 is a Sunday, so the period runs until the end of Monday, June 15, 2026.

A defense team might set internal milestones before June 15 for client information, document review and attorney approval. Those are workflow dates, not rule deadlines. Rule 21a(e) treats a certificate of service as prima facie evidence of service, so keep the certificate with the matter’s tracking record.

FAQs About Texas Discovery Deadlines

How long do you have to respond to discovery in Texas?

A written response to interrogatories, requests for production or requests for admission is due within 30 days after service under Tex. R. Civ. P. 197.2(a), 196.2(a) and 198.2(a). A defendant in a Family Code suit served before its answer is due need not respond until 50 days after service. A court order or Rule 11 agreement can change the date (Rule 191.1).

When are initial disclosures due in Texas?

Initial disclosures are due within 30 days after the first answer or general appearance is filed, unless the parties agree or the court orders a different time (Rule 194.2(a)). A party first served or joined later has 30 days from service or joinder. Rule 194.1(a) excludes Family Code suits, and Rule 194.2(c) lists other exempt proceedings.

When does discovery end in a Texas Level 2 case?

In a suit not governed by the Family Code, the Level 2 discovery period ends at the earlier of 30 days before the date set for trial or nine months after the first initial disclosures are due (Rule 190.3(b)(1)(A)). In a Family Code suit it runs from filing until 30 days before trial. A Level 3 order can set a different period (Rule 190.4).

Does electronic service add three days to Texas discovery deadlines?

No. Rule 21a(c)’s three-day extension applies to service by mail, not electronic service. Under Rule 21a(b)(3), electronic service is complete on transmission to the serving party’s electronic filing service provider. Rule 4 then excludes that day, and a weekend or holiday last day moves to the next day that is not one.

What happens if you miss a request for admission deadline in Texas?

If a response is not timely served, the request is considered admitted without the necessity of a court order (Rule 198.2(c)). An admitted matter is conclusively established unless the court permits withdrawal or amendment, which requires good cause and findings on undue prejudice and the merits (Rule 198.3). The rule routes relief through the court’s permission, not through serving a late response.
