A credit union may not permit its directors, officers, or employees to retain any compensation for acting as co-fiduciary with the credit union in the administration of a fiduciary account, except with the specific approval of the board of directors. In addition, a credit union may not permit any fiduciary officer or employee to accept a bequest or gift of fiduciary assets, unless the bequest or gift is directed or made by a relative of the director, officer, or employee or is specifically approved by the board of directors.
