Plain-English Summary

This rule sets the quality an affidavit must have to count on a summary-judgment motion. Each supporting or opposing affidavit must be made on personal knowledge, set out facts that would be admissible at trial, and affirmatively show that the signer is competent to testify to those facts.

The standard keeps the summary-judgment record tethered to evidence a jury could hear at trial — not hearsay, speculation, or conclusions. An affidavit that fails the test carries no weight in deciding whether a real factual dispute exists.
