In such a situation, the petitioning spouse (i.e. the one filing for divorce) can be granted a "divorce by default". The way it works is, so long as a valid summons and complaint has been filed with the court and the respondent (i.e. the non-filing spouse) has been properly served, the petitioner is entitled to a divorce if the respondent fails to file an answer within the set time period (typically 30-60 days). After that, they will be considered to have "defaulted". Consequently, the petitioner can then file the final paperwork and appear in court; the judge will rule based solely on the petitioner's testimony. A divorce is then granted on the terms requested.
