The Will and Marriage LIcense
If Connie had never revealed her true identity and Bill had never figured it out, she wouldn't have inherited anything from the will because it would have been Patricia's name on it. Therefore, she really had nothing to be worried about when the mom signed it.
As for getting married, Bill and Connie would have had to get a wedding license before heading to the alter. If the marriage license had Patricia's name on it, the marriage wouldn't be legal. Everyone except Bill was calling her Patricia up until she corrected the priest during the ceremony. Bill doesn't even come clean that he knows until the night before the wedding. Therefore, they either got a marriage license with Patricia's name on it voiding their marriage, or they had a ceremony and planned on getting a license later.
