Because you want to buy a house so soon I would get an attorney...........she must answer the court papers and at times the court date may change. Make sure that you get an attorney that will not offer to settle before he gets descovery!!!!! The info. in the DV is what he will ask for in descovery.
If you do not get an attorney....she must appear in court......make copies of the DV letter CERT paper and GG.............take all the originals to court (keep the copies at home) They might help her.
Never admit to any debt!!!! make them prove it. There is always a chance that they will not show up in court.
