Help my Grandkids!

My daughter is embroiled in a terrible custody fight with her ex-husband.  She left him after his affair with another woman resulted in a child; his new wife has now inherited money which he is using to fund a legal campaign.  My daughter needs to be able to fight this on something like equal terms.  I am looking to raise volunteer money to help my daughter keep our grandchildren.

This has been going on for four years now with no end in sight.  My daughter's ex is emotionally abusive and is purposely encouraging parental alienation in our grandchildren.

Any help any of you can provide our family is deeply appreciated.  There are three children caught in the middle of this, and we all want it resolved quickly.
