Among the Ask a Divorce Lawyer questions answered today by Cordell & Cordell attorneys:

• My daughter will turn 18 in a few days and will graduate from high school in May. When should I petition the court to discontinue child support?
• Should I require that my ex come back to the state our divorce is in and get a modification to include out-of-state visitations?
• Can my passport be denied if I owe child support?
• What options do I have to increase my chances of obtaining custody of my unborn child?
• Can my spouse file for child support when we are separated but not divorced yet?
• How can I protect my property when I move out during the divorce process?
• Can I as the paying parent withhold some money from child support in order to pay  her half of our child's medical expenses?
• My son is 18 and lives in a home for autistic kids off SSI benefits. Do I have to keep paying child support for him if he doesn't receive any of it for living expenses?

Question: I currently owe back child support and have been current on payments for four years while a portion of it goes to arrears. I have since married a British woman who moved back to Britain for a job.

When I applied for a passport to go join her, I was told I was on a denial list by the child support agency apparently because of the back support owed. 

Can they refuse me a passport to be with my wife because of this? Would this be considered a hardship exception?
