A domain can have problems with transfer if:

1. It's been with its current registrar for less than 60 days. You can calculate this from the domain's whois record.
2. A payment is due on the domain. If your domain is with Network Solutions, you can check payment status at payments.networksolutions.com. Check the date of your whois record.
3. The confirmation request email is not replied to in time. We allow a week for the reply, and then the transfer request will be canceled.
4. The domain name and Unique ID were not filled in exactly as given in the confirmation email. Make sure there are no extra spaces.
5. You're not currently the Administrative Contact. If the confirmation email to transfer your domain does not go to your email account, this will cause a problem. You should first either modify your domain record with the current registrar so that you are listed as the domain administrator, or make arrangements with the person who is for confirming the transfer.
