They will likely have her DFED in absentia without her even knowing it if she sends them a letter on her own. Contacting an attorney then would be closing the barn door too late. Very bad advice.
The blood thirsty sharks, I mean elders, will view her passivity and or non compliance as fear and guilt. Blood in the water.
So you can be a passive victim, which has a 100% likelihood of failure, or you can immediately get an attorney and prepare to fight Back
Hard. The success rate isn't 100%, but it is a lot better than the alternative.
We are assuming by your posting this that being DFED isn't a desirable outcome. If it is, ignore.
