When a case proceeds by default
If the other spouse was properly served and does not respond within the allowed time, the case can generally move forward without them. In New York this is handled as an uncontested divorce, with the filing spouse submitting proof of service and the remaining papers for the court to review. The judge still reviews those papers with care, starting with whether service was valid. Relief is usually limited to what was asked for in the papers that were served, so a default does not let anyone add new demands later. Financial and parenting terms still have to be supported by what is in the file.
When the spouse cannot be found
Proper service is the step that most often goes wrong. If you do not know where your spouse is, a court can permit another method, such as publication or, in some cases, service by email or social media, but you usually have to show the efforts you made to find them first. Keep a record, with your lawyer's guidance, of the addresses tried, messages sent, and people asked. Before a default judgment is entered, federal law generally requires a statement about whether the absent spouse is in military service, and added protections apply if they are. Courts take these requirements seriously because the absent spouse's rights are at stake.
If the default is challenged later
A spouse who defaulted can ask the court to set the judgment aside, typically by showing both a reasonable excuse for not responding and a defense worth hearing. Defaults resting on defective service are especially vulnerable. Getting service right at the start, and keeping careful proof of it, is what protects the judgment over time. If you are the spouse who missed the deadline, act promptly, because waiting can make reopening harder. In a first meeting we review the service history and decide whether to proceed, serve again, or respond, and we talk about what a later challenge could unwind.
