If the husband and wife are selected as winners, what to do?

The dv 2010 visa lottery allows a married couple to apply one entry each including the other with the eligible children if both of them meet the education/work experience requirements. At the KCC when the entries accepting time is over computers will randomly will select nearly 1,00,000 winners to issue 50,000 immigrant visas to eligible.
As married couples are allowed to send two entries for a family there are chances that both entries are selected as winners from the same family. If the husband and wife both receive winning notifications, one of them must stop further processing with the winning notification. This is according to the dv lottery regulations.
