Is it ok to referee a game of a family member so long as it is fairly administered etc.? If so, are there any disclosures recommended or required prior to the match to allow the coaches to make the call?
USSF answer (September 24, 2008):
The referee (or assistant referee) should turn down the assignment to such a game as soon as it is offered. To referee such a game other than in the most dire emergency is a violation of the Referee Code of Ethics.
That said, we understand circumstances may call for someone associated with the team to fill in as an assistant referee and, as long as both teams are aware of the situation and do not object, this may be the only practical way of ensuring full coverage on a match.
