There are some restrictions on what you may choose as your new name. Generally, the limits are as follows:

• You cannot choose a name with fraudulent intent -- meaning you intend to do something illegal. For example, you cannot legally change your name to avoid paying debts, keep from getting sued or get away with a crime.
• Your new name cannot interfere with the rights of others, which generally is defined as choosing the name of a famous person with the intent to mislead. For example, most judges will not approve your renaming yourself George Bush or William (Bill) Clinton unless you have a convincing reason not related to the famous politicians.
• You cannot use a name that would be intentionally confusing. This might be a number or punctuation -- for example, "10," "III," or "?."
• You cannot choose a name that is a racial slur.
• You cannot choose a name that could be considered a "fighting word," which includes threatening or obscene words, or words likely to incite violence.

Yes, anyone can do a name change. In theory, most states allow you to legally change your name by usage only -- meaning that you simply start using your new name without any court action, and at no cost.

However, practically speaking, because you don't have a marriage certificate, you will need an official court order changing your name before you'll get government agencies and many private companies, such as banks and title companies, to accept your new name.

Whether you have changed your name by usage or by court order, the most important part of accomplishing your name change is to let others know you've taken a new name. Although it may take a little time to contact government agencies and businesses, don't be intimidated by the task -- it's a common procedure.

The practical steps of implementing a name change are:

• Advise officials and businesses. Contact the various government and business agencies with which you deal and have your name changed on their records. See Changing Identification and Records, below.
• Enlist help of family and friends. Tell your friends and family that you've changed your name and you now want them to use only your new one. It may take those close to you a while to get used to associating you with a new sound. Some of them might even object to using the new name, perhaps fearing the person they know so well is becoming someone else. Be patient and persistent.
• Use only your new name. If you are employed or in school, go by your new name there. Introduce yourself to new acquaintances and business contacts with your new name.

As long as you're changing to your new spouse's name, or returning to your old name, you can usually use the usage method to change your name after you get married or divorced -- you simply start using your new, or old, name. You'll need to provide proof of your name change, but showing your marriage certificate or divorce decree should be enough. However, if you want to change to a new name (for example, you and your new spouse are both taking on a name that's new to both of you, or you want a new name after a divorce) you'll have to get a court order.
