Flat Fee. Where a legal matter is simple and well-defined, lawyers typically charge a flat fee. Examples of flat fee matters include wills, uncontested divorces and simple bankruptcy filings. If an attorney suggests or has advertised a flat fee, be sure you understand exactly what that fee will and will not cover.
The definition of wily is  something or someone who is cunning and sly. An example of wily is a bank robber whose picture never gets caught on a surveillance camera.
Willful means deliberate or stubborn.. A child who exhibits willful disobedience knows she is doing something wrong (even if she tries to convince you otherwise). While being full of will, or determination, doesnât necessarily seem like a bad thing, the word willful is negative in meaning. Use it when someone is behaving in a stubborn or uncooperative manner.
