That is pretty easy to do. All you have to do is file a Motion to Set Aside Default Judgment with the clerk of court where the action was originally filed. You will probably also need to file an affidavit. The clerk should have the paperwork for you to fill out.
In deciding whether to set aside a default judgment, courts seek to balance two competing interests: (1) the need to promote judicial economy; and (2) the need to preserve an individual's right to defend on the merits. Therefore, in addition to the requirement that defendant show that the judgment was entered through excusable neglect or another statutory ground, the court will consider a variety of factors, including:
1) the nature and extent of the prejudice which may be suffered by the non-defaulting party if the default is set aside;
2) the presence of material issues of fact;
3) the presence of a meritorious defense to the claim;
4) the significance of the interests at stake, including, but not limited to, the amount of money involved;
5) whether the failure to answer was intentional or willful or the result of conscious indifference;
6) whether party or counsel bears responsibility for default; and
7) the availability of less drastic sanctions.
Just make sure you have a good reason for not showing up at the original court date and you should be okay. Please feel free to come back here and ask me additional questions if you need help after you get the forms.
