Except to the extent that it violates public policy, a testator may:
1. Make a devise conditional upon a devisee’s action or failure to take action or upon the occurrence or nonoccurrence of one or more specified events; and
2. Specify the conditions or actions which would disqualify a person from serving or which would constitute cause for removal of a person who is serving in any capacity under the will, including, without limitation, as a personal representative, guardian or trustee.
