Un lawful green card

Her father may have applied for it in 2005. We don't know. OP doesn't know either.

Or possibly before 2005 (it would have to be before 2005 if their immigrant visas have already been granted). The 2005 attempt to get the OP to sign the document could have been the result of the consulate requesting that document during the later stages of I-130 processing.

You're right, the OP doesn't know the full details, but whatever the case is, the consulate needs to be notified ASAP.
