Mechanism 22
Verified denial — defect of parties
When must a denial be verified under Texas Rule of Civil Procedure 93?
Rule 93 lists the pleas that must be verified by affidavit or they are waived — among them that there is a defect of parties, that the plaintiff is not entitled to recover in the capacity in which he sues, that the defendant is not liable in the capacity in which he is sued, and denial of the execution or of an account. A general denial does not preserve any of them.

When it applies
Most often when a vendor sues the wrong member of a corporate family — the contracts run to two affiliated operating entities and the plaintiff has named the parent, or the brand, or the wrong affiliate. A verified answer puts the burden back before a dollar of merits work is done.
How it is proved up
- Identify the actual contracting parties and attach the contracts showing it.
- Verify the answer — a sworn statement from someone with knowledge of the corporate structure, not a certificate from counsel.
- Plead the specific Rule 93 subsection rather than a general reference to the rule.
- Where the correct entity is a client too, decide early whether to name it, because limitations may be running.
What defeats it
- Truth appearing of record already, which excuses verification.
- An amended petition naming the right entity, which cures the defect if limitations permits.
- Alter ego, single business enterprise or assumed-name theories that reach the named defendant anyway.
Where I have used it
Vendor suit, County Court at Law No. 4, Williamson County. Verified answer establishing that the contracts ran to two affiliated operating entities and not to the defendant named.
Questions
What must be verified under Rule 93 in Texas?
Among others: that a party is not liable in the capacity sued, that there is a defect of parties, denial of a partnership or corporate existence as alleged, denial of the execution of a written instrument, denial of an account, and that a contract sued on is usurious.
What happens if a Rule 93 plea is not verified?
It is waived. A general denial does not raise these matters, and raising them for the first time at trial or on appeal is too late.
Can a defect of parties be cured by amendment?
Yes, if the plaintiff amends to name the correct party and limitations has not run. That is why the verified denial is most valuable filed early — it forces the correction while the calendar still matters.
