Three forums that get confused
A criminal case is brought by the prosecutor, and the person harmed is a witness rather than a party. A family offense petition in New York Family Court is a civil proceeding that relatives and current or former intimate partners can file to ask for an order of protection, and it can run beside a criminal case. A civil lawsuit for money damages is a third path, usually filed in a general civil court and based on claims such as assault or battery. New York City also has a gender-motivated violence law whose filing window has been reopened by local legislation and whose reach has been litigated, so its current status needs checking for any particular claim.
Deadlines and overlap
Civil claims for intentional harm can carry filing periods that are shorter than people expect, so waiting for the criminal case to finish is not always safe. On the other side, a person accused in a civil case who also faces criminal charges has to think carefully before answering questions under oath, because testimony in one case can be used in the other. A criminal conviction can sometimes be used in the civil case to establish what happened. Insurance policies often exclude intentional acts, which affects whether there is any coverage for a claim or a defense. These interactions are why the cases are usually planned together rather than one at a time.
Preparing either side
Keep medical records, photos, messages, police report numbers, and the names of anyone who saw or heard what happened. If an order of protection exists, it controls contact, and nobody should use the lawsuit as a reason to reach out privately. Do not post about the dispute online, because posts tend to surface as evidence. Our first task is sorting out which proceedings are already open, which deadlines may apply, and whether you are the person seeking relief or the person responding. From there we can talk about where the dispute is likely to be decided and what each forum would require of you.
