Once reached the date of expiration, the domain, the website and the post office they will stop working. This period lasts 36 days for the most habitual extensions (.com, .net, .org, .info)
During this term the proprietor of the domain has the option to renew the domain without rates extra.

After the period of Expiration, a domain can be registered by third parties by means of the calls backorders, reason why the domain him can be snatched.

In case of not existing backorders it spends to one second called stage the period of redemption (or in delay).
During 30 days as much the proprietor of the domain com third parties by means of backorders, has the option to renew/to register the domain, but in addition it will have to pay some additional rates that go up to around 60-90‚¬ following the extension of domain.

Once finalized the period of redemption, the domain flock of the registry and is left at the disposal of the public as Available.

As minimum, it is necessary to ask for the transfer 10 days before the domain expires, since it is the approximate term so that a transference is completed.
I recommend myself to begin the proceedings in advance (30 days) to have sufficient margin in case there is some problem.

Normally the transference implies a year more of registry.
If the domain has been renewed recently with another recorder, it agrees not to transfer it until pasts 45 days.
Of thus not doing it, although it can be transferred, one will not add a year to the date of expiration.

It will not be able to again transfer until pasts 60 days

A expired domain cannot be transferred.
It must be renewed by his present recorder, or must be expected all the terms of redemption until it is free.
