Yes, they do.
No you are not. It is the noncustodial parent's responsibility to make arrangements to visit the child. All this should be included in your custody papers.

By applying to a court.
by whom?
Child support and custody/visitation are separate issues. You should contact your local courts to file for visitation/custody if the custodial parent is denying visitation.
The child's custodial parent could be held in contempt of court for failing to abide by court ordered visitation and incur a fine, jail time or both. If the problem becomes chronic, the courts may order a modification in custody, giving the non-custodial parent primary physical custody.

Whether or not the noncustodial parent has the right to take custody of the minor children if the custodial parent is incarcerated depends on the specific circumstances and any existing court order or custody agreement. In general, it is recommended for the noncustodial parent to consult with a family law attorney and go through the appropriate legal channels to modify or establish custody arrangements during the custodial parent's incarceration.
In difficult custody battles, it's best to keep a journal detailing things such as this. This can help when providing facts to the court showing a lack of interest in following any visitation agreements. Non-custodial parents can petition the court requesting a change in custody, but Judges do look at the facts, and take what is called status quo into account.
The non-custodial parent should file for visitation rights for the child in the county where custody was given. If the parent who has custody of the child is preventing the non-custodial parent the right of visitation they can be found in contempt of court if visitation has already been established. If the custodial parent has too many repeated contempts filed against them, custody can be switched to the other parent.
