Tex. R. Civ. P. 86

1. Time to File. An objection to improper venue is waived if not made by written motion

filed prior to or concurrently with any other plea, pleading or motion except a special

appearance motion provided for in Rule 120a. A written consent of the parties to transfer

the case to another county may be filed with the clerk of the court at any time. A motion to

transfer venue because an impartial trial cannot be had in the county where the action is

pending is governed by the provisions of Rule 257.

2. How to File. The motion objecting to improper venue may be contained in a separate

instrument filed concurrently with or prior to the filing of the movant's first responsive

pleading or the motion may be combined with other objections and defenses and included

in the movant's first responsive pleading.

3. Requisites of Motion. The motion, and any amendments to it, shall state that the action

should be transferred to another specified county of proper venue because:

(a) The county where the action is pending is not a proper county; or

(b) Mandatory venue of the action in another county is prescribed by one or more

specific statutory provisions which shall be clearly designated or indicated.

The motion shall state the legal and factual basis for the transfer of the action and request

transfer of the action and request transfer of the action to a specific county of mandatory

or proper venue. Verification of the motion is not required. The motion may be

accompanied by supporting affidavits as provided in Rule 87.

4. Response and Reply. Except as provided in paragraph 3(a) of Rule 87, a response to the

motion to transfer is not required. Verification of a response is not required.

5. Service. A copy of any instrument filed pursuant to Rule 86 shall be served in accordance

with Rule 21a.
