You should contact a local attorney to review the documents you prepared on legal zoom. If you wrote a property settlement agreement, it should be reviewed before you sign it.

Co-owning a home post-divorce usually does not end well. Because you are not refinancing the mortgage, your Wife will probably be unable to purchase a home on her own because this mortgage remains on her credit.

How long was the marriage? You really should consult local counsel.
