There are many reasons people choose to appeal and many factors to consider such as the cost of appeal, the likelihood of success, the time and mental energy involved, whether you will have to pay any costs or attorney fees to the other side if you do not prevail or whether the judgment below is enforceable pending appeal.
There are also other post-judgment options such as a motion for reconsideration, motion to vacate, motion for a new trial or a motion to re-open the trial. All post-judgment options have a short deadline. If you are considering any post-judgment motion or an appeal you will need to speak with an attorney as soon as possible.
