Why am I seeing someone else's contacts?

[aznative]

Every time I do a backup on my contacts, all my husbands contacts show up in my list! I delete them and they show up again! My contacts are syncing with his also. I have looked in my settings, cannot find the reason.

Are you sharing the same applied on your icloud settings?

Look in Settings / Mail, Contacts, Calendars - That is where I think you are sharing the same iCloud account

Using the same credit card for two separate iCloud accounts can cause funky behavior, including merging some data. Music especially. Using separate credit cards for each iCloud account might solve your issue.
