My name is XXXXX XXXXX I'd be happy to answer your questions today. I am very sorry to hear that this has happened.
I'm sorry to have to tell you this, but the law unfortunately does not support you, based on the facts that you have provided. The law typically defers to a parent's wishes regarding who will spend time with his or her children. There are some exceptions, but those apply in situations where the grandparent previously was the custodial parent
for at least one year, it has already been determined that the child does not have proper care (such as where Child Services removed the child from the home), or there is reason to believe that there is neglect, abuse, or mental illness on the part of the parent. 23 Pa. Cons. Stat., Section 5324
I really hope that your daughter comes around before it's too late for you to establish a relationship with your grandchildren. The child/grandchild relationship is very special, and very different from the parent/child relationship. But the law unfortunately does not provide a right to visitation where the parent has chosen to deny access, outside those three exceptions.
I apologize that this was probably not the Answer you were hoping to receive. However, it would be unfair to you and unprofessional of me were I to provide you with anything less than truthful and honest information. I hope you understand.
