Quick answer
Usually no. You may still need proof of valid service, required filings, and a court judgment.
Do now
Keep service documents and check the docket. Ask the clerk or a lawyer about the proper default procedure and required evidence. Continue complying with disclosure and hearing requirements.
Watch for
A default can be challenged in some circumstances. Military service, defective service, missing notices, and requests affecting children or property require special care. Do not treat an unsigned proposed judgment as a final divorce.
