The courts should never draw an unfavorable inference from a party changing attorneys. A party should be able to choose whomever they want to represent them. However, as a practical matter, judges always wonder why a client has had so many previous attorneys. Is it due to unreasonableness or failure to pay a bill?
Practically, no negative inference should be drawn due to a change in attorney of record. Be mindful that the courts will always wonder why multiple changes occurred. Switching once is probably acceptable. More than once probably raises the eyebrows of the court.
