My daughter was subpoenaed to testify in a domestic assault case against her boyfriend. She has to be out of town. Is there any way we can get the court date changed?

I suggest you contact the Clerk of the Court as soon as possible or instruct your legal representative to do so.

There would have to be compelling reasons for the case to be adjourned and your daughter would probably need to explain why her being out of town is more important.

Not only do I doubt your success but your description indicates your daughter is a key witness in a case that is in her own benefit, which without her testimony could be thrown out or the defendant found not guilty.

In addition, ignoring a subpoena could result in a charge of "contempt of court".
