Courts can award attorneys fees for default judgment if they are allowed by statute or under the contract. The fees would be based on the amount of time expended to get the default. If you want to have the default removed and have the case continued, that might be possible. You can attend the hearing as 5/12 is Wednesday. I would suggest consulting with an attorney about the merits of your case. But yes they can get attorneys fees for a default.See question
If she was invited to stay and now won't leave when asked this could be a case of unlawful detainer. You are going to need a court order to remove her.
