Can evidence at a family child custody case still be presented at the hearing if I wasn't able to get it in before discovery ended?

You asked: Can evidence at a family child custody case still be presented at the hearing if I wasn't able to get it in before discovery ended? Answer: Probably not, but nothing ventured, nothing gained. It can't hurt to try and present the evidence. The worst that can happen is that the court refuses it. If a witness does not appear in response to being subpoenaed, the court should issue a warrant for the witness's arrest and you could ask (ask, not demand) that the hearing or trial be continued until the witness is located. In practice, however, a witness who doesn't show *usually*results in the hearing or trial taking place without that witness's testimony and you're out of luck.
