Child custody

We are from Faisalabad and living in islamabad since 4 years and have proved this in court. My daughter is divorced.
We filed the child custody case in faisalabad. Now they are asking for a meeting with the child. They filed the case at wrong address in faisalabad, which we found out later. Will the decision made by the court in faisalabad be accepted/valid in islamabad? Our lawyer told us that the decision here in islamabad will not be affected , and the meeting with child will also take place here in islamabad and the child will not be taken to faisalabad. Is this correct?
