Practice Pointer: If you don't have a law license….

If you don’t have a law license, then you probably should not practice law.

If you decide to practice law anyway, and the court orders you to stop, you should probably stop.

If both of those things happen, and you don’t stop, you really shouldn’t sue your client for $845,000 in unpaid legal fees.

Strangely enough, that is how far you seem to need to go in order to be prosecuted for the unlicensed practice of law in Massachusetts. (source)
