§ 8.01-6.1.Amendment of pleading changing or adding a claim or defense; relation back.

Section 8.01-6.1 fills a gap next to § 8.01-6: it addresses amendments that change or add a claim or defense, rather than amendments that change which party is named. Subject to other applicable law, such an amendment relates back to the date of the original pleading for limitations purposes if the court makes three findings — the claim or defense in the amended pleading arose out of the conduct, transaction, or occurrence set out in the original pleading; the amending party was reasonably diligent in asserting the amended claim or defense; and the parties opposing the amendment will not be substantially prejudiced in litigating the merits because of the timing of the amendment.

The section gives the trial court a tool to soften the effect of allowing a late amendment: it may grant a continuance or other relief to protect the parties in connection with the amendment. That flexibility lets the court permit the amendment while still managing any disruption it causes to trial preparation or scheduling.

The section carves out two categories entirely. It does not apply to claims or defenses in eminent domain proceedings or in mechanic’s lien cases, so relation back for amendments in those areas depends on other law rather than this section.
