mariagoretti advice is the best.
I've sat in with women accused of MSBP/FII and in every case the false accusation could be avoided had the 'victim' known it was coming, or likely to come. Being aware of the possibility is normally enough to avoid an accusation, you can be on your guard and take the suggested steps to avoid a false accusation.
In essence you can find yourself walking on eggshells with these people; the MSBP/FII mechanism is so easy to use that it is routinely abused by those inclined to employ it. But it needs a consensus of individuals to allow it to be employed against a woman. There might be no-one in the meeting inclined to employ it, but it only takes one to take exception against you and in the false allegation goes.
Presenting yourself as being critical of the suggestions made ("I see no evidence") is a fast-track to a false accusation. The nature of the use of the MSBP/FII false allegation regime is such that this is the most popular 'trigger' for it; being critical of service providers. The other trigger is if a woman comes over as too 'vulnerable' or 'needy' in which case the false allegation goes in just to satisfy a vindictive desire to teach a woman 'a good lesson'.
You might just have to simply nod dutifully, hold your tongue, put your brain into neutral (some of these people hate the concept of intelligent women) wear a wimple and accept that you have to run through the hoops and obstacles that your are presented with, if ultimately you get either what you want, or something useful. The key is to not say anything that might sound even vaguely out-of-turn, and don't dispute anything unless it is crucial for your cause.
If all this sounds bizarre, like it's advice lifted from the 17th century - then it is. The world of MSBP/FII is unlike anything experienced by women in the UK for centuries, and the false allegation regime has been in place until at least 1997. It is peculiar though to the UK - women in say the Spain or France or Sweden will never have to worry about such matters. In the US the false MSBP/FII regime is restricted really to divorce/allimony hearings.
It tickles me sometimes when I see a MumsNet discussion about going to Feminism in London 2010 or some similar event; the issues of how women are routinely abused by officialdom in these situation are NEVER discussed at these events, and some of the abusers will be those who profess themselves to be 'feminist'.
There is lots of good advice on the 'Net. Most of it though relates to women who run into the MSBP/FII false allegation regime with respect to Autism Spectrum Disorders. Nonetheless, the experiences of Janet Loxley-Blount are well worth reading.
