Adept at managing high-conflict, approachable, military friendly

I highly recommend hiring Tanya Sanscartier for any issues involving child custody and child support.Tanya was kind, understanding and experienced working with military families. During my two years working with her she tackled child custody, child support, and move-away orders with a contentious co...-parent. She was always straight forward with me regarding my expectations and reality. However, as a result of working with her, I was granted sole custody, child support and approved to move-away, and I know I would not have been able to achieve that on my own. Hiring her meant not having to directly deal with any of the backlash of notifying my ex of court notifications or having to respond to any of the taunting from my ex in court. She was also very transparent with any communications she sent to my ex. She effectively knew when to engage and when to hold off replying - which allowed me to use my funds more strategically. I thoroughly enjoyed working with everyone at Happ Law Group, they were all very kind and knowledgeable. I am glad that I hired them and would work with them again in the future, if needed.

Outstanding Attorney – Supportive, Strategic, and Truly Caring

I worked with Tanya for nearly two years through a long and emotionally difficult process involving divorce, child support, and custody. From the beginning, she was the perfect mix of kind, friendly, supportive, and firm. Tanya truly listened to all of my concerns and represented them with accuracy, ...professionalism, and compassion. She was always communicative, responsive, thorough, and timely. These qualities made a huge difference during such a stressful time. She set realistic expectations but consistently overdelivered. Thanks to Tanya’s dedication and advocacy, I now have sole legal custody and my ex has supervised visitation. This outcome reflects her ability to navigate complex family dynamics with strength and precision. Custody is an ongoing battle, and I will absolutely continue working with her. I’m incredibly grateful for her support and highly recommend Tanya to anyone going through a divorce with kids.

Exceptional experience with Happ Law Group

I had an exceptional experience with the Happ Law Group. Tanya was not only incredibly easy to work with but also impressively attentive to every detail. Her responsiveness and thorough handling of all the paperwork made the process smooth and stress-free. I highly recommend her and the Happ Law Grou...p to family and friends!

Skilled and knowledgable family law lawyer

I had the pleasure of being represented by Tanya Sanscartier during my divorce case, and I couldn't be happier with the outcome. She was incredibly organized, knowledgeable, and compassionate throughout the entire process. Tanya took the time to understand my situation (which involved a divorce cas...e spanning two states), provided clear guidance, and always kept me informed. Her expertise and dedication to my case ensured a fair outcome, and I felt supported every step of the way. Furthermore, Tanya’s ability to balance the necessary legal procedures with cost efficiency ensured that I received excellent representation without unnecessary expenses. I highly recommend Tanya to anyone in need of an outstanding family law attorney.
