When must all other Texas testifying experts be designated?

Establish the complete discovery plan, endpoint and designation order.

Check that the expert does not testify for a party seeking affirmative relief under the ninety-day branch.

Prepare the actual required disclosure information and separately establish deposition availability.

1. Establish the complete discovery plan, endpoint and designation order.
2. Measure the ordinary sixty-day limb from the discovery endpoint, not trial or the opposing expert’s designation. The court’s actual order may govern a different date. Family Code cases require the separate service comparison under Rule 195a.2.
3. Read any signed order and establish the actual required act, recipients and completion method.
4. Check closed days without silently shortening the required interval.

These periods exceed five days, so Rule 4’s exclusion of intermediate Saturdays, Sundays and legal holidays for short periods does not apply. Do not move a latest date forward toward trial, a hearing or discovery closure merely because the nominal date is closed. That can leave less than the required lead time. Check Rule 4, the controlling order and actual court calendar. This source guide applies no automatic backward closed-day adjustment and supplies no computed last date.

Complete actual service under the applicable rule. Rule 21a distinguishes permitted service methods from filing. Electronic service completes on transmission to the serving party’s electronic filing service provider. Fax received after 5 p.m. in the recipient’s time zone is deemed served the next day. The three-day qualifying-mail addition in Rule 21a(c) concerns a prescribed period after service, not an automatic addition to a backward trial or discovery limit. Preserve recipients, method and completion evidence.

The isolated sixty-day preset does not determine the actual role, controlling endpoint, Family Code service comparison or court order. Its backward review setting cannot resolve a closed-day last date. This guide supplies no calculated endpoint.

Role rather than caption

The sixty-day category is all other experts after excluding those testifying for a party seeking affirmative relief. A defendant’s affirmative claim can matter to the actual expert role.

Required information

Rule 195.5(a) requires contact information, subject matter, opinions and their basis, with additional listed items for a retained, employed or controlled expert. A designation date does not establish complete disclosure.

Family Code later-of rule

Rule 195a.2 ordinarily chooses the later of thirty days after request service and the applicable sixty-day-before-discovery-end limb for this role, unless the court orders otherwise.

Deposition sequence

Rule 195.3(b) requires a controlled expert for a party not seeking affirmative relief to be available reasonably promptly after designation and after affirmative-relief experts on the same subject have been deposed.

• Furnish the applicable Rule 195.5(a) information to the other parties. Serve discovery material on all parties of record under Rule 191.5 and retain completion evidence. Rule 191.4 ordinarily keeps this party discovery material out of the clerk’s file unless an exception applies. Expert designation and the later deposition are distinct acts.
