Must a Texas trial court file findings on an interlocutory appeal?

Identify the actual interlocutory order and establish signing.

Separate the court’s optional findings from any party request.

Independently establish appealability, the appeal type and the actual accelerated filing timetable.

1. Identify the actual interlocutory order and establish signing.
2. Exclude the actual triggering event and count every intermediate calendar day under Rule 4.1(a). Do not import the Civil Rules’ short-period exclusion into appellate computation. A signing, rendition, filing or ruling date must be established from its own actual record. The thirty-day wording describes an optional court action. It does not impose an automatic filing obligation on a party.
3. Apply Rule 4.1 and establish the actual clerk calendar.
4. Complete the required act in the correct court.

Rule 4.1(a) moves a final Saturday, Sunday or legal holiday to the next eligible day. Rule 4.1(b) separately extends a filing period when the proper clerk is closed or inaccessible during regular hours on the final day, until the next open and accessible day. Preserve the required proof. The encoded Texas holiday calendar covers 2026 through 2028; it does not know additional local closure or system failure.

Rule 28.1(c) concerns optional judicial action rather than one required party filing. A mandatory computed date would misidentify the actor and obligation.

The court need not file findings

Rule 28.1(c) expressly makes interlocutory findings optional while stating the thirty-day period for that court action.

Requests do not extend accelerated perfection

Rule 28.1(b) says a new-trial motion, another post-trial motion or a findings request does not extend accelerated perfection time. Establish the actual notice period separately.

Trial permission must be established in the actual order

Civil Rule 168 requires permission in the order to be appealed and allows amendment of a prior order to include it. The permission identifies the controlling legal question and substantial disagreement, and explains how immediate appeal may materially advance termination. Establish statutory eligibility separately; this calculator does not grant permission.

• The consolidation date does not establish applicability of every historical amendment. Read the actual governing edition and orders.
