Update: Case Closed! I just want to say thank you to the whole Kasper and Lugay Team! Brent got The “W” in my case. They worked hard on my child custody battle and were super flexible with my payments! Anyone that’s going through a separation knows the stress courts can bring, but Brent and his team made sure to make everything fast and easy as possible for me! Thank You Again! I hope I never have to go through something like this again but if I ever do I know who to call!

I hired Brent Kaspar & his team to assist me in the dissolution of marriage from my wife of 9+ years and love for 14+ years. This is obviously not any type of experience anyone want to go through, however I wanted the best direct & logical approach as the emotional & financial sides of this transition are difficult enough. Brent impressed me immediately with his knowledge of the process as well as his experience with every local attorney, mediator, judge, and whomever else I may be faced with addressing.... I would want him on my side.

My case was not simple or easy. After 5 years, my ex-husband, decided to try and terminate all alimony on a 26 year marriage, as well as obtain funds from me....The process with Brent Kaspar and this entire group was very thorough as well as methodical to achieve the end goal. Although there is always a high amount of stress when dealing with any legal matter, these individuals as are excellent at their jobs, relentless on getting information, light hearted when need be, and strong willed when dealing with others legal nonsense. We were able to settle prior to court and obtain/protect what I intended.
