trying to buy a home in forclosure and running into problems

[N/A N/A]

ok, we found the perfect home for us, great price everything. It is a Fannie Mae foreclosure, everything went smooth until they did the title search and found that only one of the owners(husband and wife were on the mortgage) were served with the foreclosure papers. now the listing agent says it will take months to complete this. Is this typical, is there any way to speed the process up? The listing agent is horrible to deal with, never returns phones(not even our real estate agent's calls), what gets me the most is that the listing agent was never to put the house on the market but she did anyway.

any advice?

thanks!
