A lawyer who is likely to be a necessary witness at a trial may not also act as advocate in it, unless the evidence concerns an uncontested point or the nature and value of the legal services provided in the case, or unless disqualifying the lawyer would cause the client substantial hardship. Another lawyer in the firm may act as advocate even though a colleague is likely to testify, unless Rule 1.7 or 1.9 prevents it.
