My son is awaiting a trial that will determine custody of his son. The current order is a temporay order for each parent to have equal visitation until until the trial and decision is court ordered. The mother has twice brought the child to our house (my son and his child live with us and pays rent) and left him here due to being evicted from her place of living. She has now found a new place and is demanding visitation. The child also just had surgery (post op day one) and we feel the place she is living is not safe nor sanitary. We are aware that by holding him here my son is in comtempt of court. The question is that she has threatened to call the police. Can she just call the police or does she need signed documents that force the issue. The court date is July 28.
