Can my mom MAKE me let her see her grandkids>?

She is mentally and emotionally abusive. I dont' let her see the kids much and want to stop it all together, but moving really far away. In the meantime I am pacifying her by letting her see them once ever now and than. I am worried she will go to court as here we have 'grandparetns rights'. Menal and emotional abuse is very hard to prove, and even harder when she is a 'pillar of the community' pastor's wife. Since I have cut back contact, my anxiety attacks have stopped and my kids have self confidenece.. my oldes child acutally plays and gets hyper (she used to be a serious and shy child). My kids dont' even have tempers and burts of sudden anger anymore! I am worried if she takes me to court because emotional abuse is 'he said, she said'. Can she MAKE me let the kids go around her? I am going to go to counselling to help me out, but also so there is doentation.. but that kind of doentation is more 'she said...' kind of stuff.
