§ 8.01-545.Amendments; formal defects.

Attachment procedure is technical enough that courts need room to fix mistakes without throwing out an otherwise valid case. This section gives them that room broadly: the petition, the answer, and any other paper in the attachment proceeding may be amended whenever doing so serves the ends of substantial justice, on whatever terms as to continuance and costs the court finds proper.

Amendments do not cost the plaintiff his priority. As against the principal defendant, and for claims that already existed when the attachment issued, an amendment relates back to the time of the levy unless the court directs otherwise, so fixing a defective petition does not hand a later-arriving creditor or lienholder priority over the original attaching plaintiff.

The section closes with a blunt instruction to courts: no attachment can be quashed or dismissed for a merely formal defect. Between the liberal amendment standard and this bar on formal-defect dismissals, the statute pushes attachment cases to be decided on their merits rather than on paperwork technicalities.
