Your friend needs to speak to counsel about his rights and how to protect them. At present any property he would acquire is subject to determination if it is marital or not. As I am often in Court call my assistant Dan London at 312-807-3990 to set up a private telephone consultation. At the consultation we can discuss the confidential details we need to craft a strategic plan. These details should not be broadcast over the Internet.
This is a general answer and does not address the specifics of your individual case. To give the specific answer you need our firm needs you to come in for a consultation.
