I want to obtain a legal alias that is completely different from my current name.?

Unless you are prepared to change your name completely, then any alias you use would have to be just that -- an alias. The problem with using an alternative name is that you would not be able to persuade the authorities to use it, you would not be able to do things like open a bank account with it, and you might even have problems with any qualifications you want to show a prospective employer (as well as explaining to such a person that any references would have to be taken up in the other name). There are people who use an alias in their professional lives (actors and authors, for example), but only by dint of explaining to interested parties (such as the taxman and the bank manager) that Scott Armstrong is really John Spencer.

It is illegal to live under an assumed name.Don't believe me ? Try it.Besides,what are you running away from ? Are you wanted ? Is your name on a no fly list ? Are you banned from getting cable TV ? Do you have outstanding debts ? Is the mother of your 8 children wanting child support ? Whats up ?

You can use your old name or you can use the new name. Either way, you cannot use both. Instead of a name change, it then becomes an illegal name change.
