Full Text of § 484.100
Plain-English Summary
This section protects the line § 484.050(b) already draws between probable validity and actual validity. Whatever the court decides under this chapter — about the claim, the amount, or the property — has no effect on any issue in the action beyond the attachment proceeding, and no effect on either party's rights in any other action arising from the same claim.
The protection runs both ways procedurally, too: the court's attachment-hearing determinations can't be given in evidence, or even referred to, at the trial of the action. A plaintiff who wins the right to attach order gains a provisional remedy, not a head start on proving the case; a defendant who loses at the attachment hearing loses nothing at trial because of it.
Frequently Asked Questions
Can a party use the outcome of the attachment hearing at trial?
No. Section 484.100 bars the court's attachment-hearing determinations from being given in evidence or referred to at the trial of the action.
Does winning a right to attach order mean I'll win the underlying case?
No. The court's determinations under this chapter affect only the attachment proceeding, not the merits of the action.
Does this protection extend to other lawsuits between the same parties?
Yes. Section 484.100 also says these determinations don't affect either party's rights in any other action arising out of the same claim.
