Mr. Begley is correct and if everything passes "by operation of law" (beneficiary designation or as a joint account), then there is no need to probate the Will. If you were omitted, rather than specifically excluded, you are deemed a "pretemided heir." (an overlooked or forgotten heir) IF there are probate assets. If specifically excluded, you probably have no claim, but as Tom has noted, if there was undue influence rather than an true intention on your father to disinherit you, you may have a claim, but such claim needs to be pursued in the state and county in which your father lived.
