Starting a sentence with “and,” “or,” or “but” is perfectly proper and is universal in good literature and legal writing. Here’s an example from Marbury v. Madison:
But where a specific duty is assigned by law, and individual rights depend upon the performance of that duty, it seems equally clear that the individual who considers himself injured has a right to resort to the laws of his country for a remedy.
“However,” however, as the first word in a sentence normally should be replaced by “but.”
