Mechanism 34
Amending a pleading on the eve of trial
Can you amend your pleadings a week before trial in Texas?
Yes, and leave is close to mandatory. Within seven days of trial an amendment requires leave — and the rule says leave shall be granted unless there is a showing that the filing will operate as a surprise. The burden is on the party resisting, and denials of leave are reversed routinely.

The authority
[A]ny pleadings … offered for filing within seven days of the date of trial or thereafter … shall be filed only after leave of the judge is obtained, which leave shall be granted by the judge unless there is a showing that such filing will operate as a surprise to the opposite party.Tex. R. Civ. P. 63

When it applies
The theory that emerged in the last deposition, the defence that appeared when the documents finally came, the damages model that changed when the expert was designated. It also matters after the evidence closes, where a trial amendment conforms the pleadings to the proof.
How it is proved up
- Ask for leave expressly and get a ruling. An amendment filed within seven days without leave may be treated as a nullity, and the record should show leave was sought.
- Frame it as not prejudicial on its face. An amendment that asserts a new cause of action or defence and reshapes the nature of the trial is prejudicial on its face; one that refines an existing theory is not.
- Offer to cure. A short continuance, a deposition, a limited document production — the offer usually answers the surprise objection.
- If you are resisting, put on evidence of surprise or prejudice. Saying it is not enough, and the burden is yours.
- Amend earlier where you can. Everything about this gets harder inside the seven days, and nothing about it gets better by waiting.
What defeats it
- An amendment prejudicial on its face — a new cause of action or defence that changes what the trial is about.
- Evidence of actual surprise or prejudice from the resisting party.
- An amendment offered after the party has rested, where the proof does not support it.
- A court order under Rule 166 setting an earlier amendment deadline, which Rule 63 expressly recognises.
Where I have used it
Chiefly on the defensive side of it — the objection that an amendment is prejudicial on its face is the one that works, and it requires the resisting party to have thought about what the trial was going to be about before the amendment arrived.
Questions
Can you amend pleadings within seven days of trial in Texas?
Yes, with leave of court, which Rule 63 says shall be granted unless there is a showing that the filing will operate as a surprise to the opposite party.
Who has the burden on a trial amendment in Texas?
The party resisting the amendment must present evidence of surprise or prejudice, unless the amendment is prejudicial on its face because it asserts a new cause of action or defence and reshapes the nature of the trial.
What is a trial amendment?
An amendment offered during or after trial, commonly to conform the pleadings to the evidence actually admitted. It is governed by the same leave standard.
