Trustee’s assignee filed a motion to amend the name of a defendant against which a default judgment had been entered. The trustee had filed a complaint to recover a preferential transfer, naming the defendant as “Signal Electric Construction,” rather than “San Jose Signal Electric Construction.” The defendant received service but did not respond, and a default judgment was entered against “Signal Electric Construction.” Limitations ran on any action the trustee might have pursued against San Jose Signal Electric Construction. Held, because the trustee lacked a reasonable excuse for failing to name the proper defendant and because the defendant had not behaved inappropriately, the motion to amend the judgment was denied.
