I sold the property that's the subject of my pending lawsuit — does the case have to be refiled in the buyer's name?

The default: the case continues with the original party

Section 19 covers what happens when the subject matter or interest at stake in a case changes hands mid-litigation — for example, a party sells the very property being fought over. The default rule is continuity: the action 'may be continued by or against the original party,' meaning the transfer alone does not force a restart of the case or automatically remove the original party from the litigation.

Substitution is available, but not automatic

The section does allow for a different outcome: the court, 'upon motion,' may direct that the person to whom the interest was transferred be substituted into the action, or joined together with the original party. This is a discretionary step that requires someone to actually ask for it — the court does not swap in the new owner on its own initiative the moment a transfer becomes known.

Why the default matters practically

Allowing the case to continue with the original party as the default avoids the disruption and expense of restarting litigation every time an interest changes hands during a pending suit. A buyer of contested property, for instance, is generally still bound by or benefits from the outcome of a case affecting that property, whether or not they were formally substituted in, which is part of what makes real property litigation binding on successors.

What happens if no one moves to substitute

If neither side files a motion asking the court to substitute or join the transferee, the case simply proceeds with the original party still on record, and the judgment eventually rendered still binds the transferred interest even though the transferee's name never appears in the caption. This is what makes the default rule workable in practice — the parties are not forced to interrupt litigation every time property or a claim changes hands, and a transferee who chooses not to intervene is not thereby shielded from the outcome. The rule does not require the transferee to intervene or even to be notified of the pending case as a precondition to being bound by its outcome, which is why a buyer of litigated property is generally well advised to check for any pending suit affecting the property before completing the purchase.
