How long do I have to answer a complaint?

The time to file an answer to a civil complaint is 20 days from the date you are served, if it is in state, and 60 days for a waiver of service. If it is out of state, you have 30 days to file an answer. If the last day falls on a weekend or holiday, you have until the end of the next business day to file.
