When your domain expires, you will be getting a grace period. If you are the original registrant of the domain name, it would be possible for you to get back the domain name during this period. However, you will also be asked to pay some additional fees. The length of the grace period and the other payment you need to pay would vary from one domain registrar to another. It will be somewhere between one week or two weeks in most instances. However, there are situations where some of the domain registrars will provide you with a grace period of one year. Top-level domain substantially impacts the grace period that you can get to the domain name.
