I am 23 and wanted to get an adult adoption for me to be adopted by my step father. John was very efficient and pleasant to work with. He knew what I needed and it was a very quick process. He made sure to keep me updated in all aspect of the case and if things weren’t getting done in a timely manner he checked in on them for us. He worked around what I could do being semi out of town. 10/10 would recommend him for any adoption needs!!

I was unsure of what to expect when I was looking to retain an attorney from out of state. I reached out to Mr. Nicholson’s office based on the reviews I saw when researching and was not disappointed. His office was very responsive, as was Jon himself. He is knowledgeable with family law (I used him for a custody case) and will keep it straight with you. He is swift, diligent, and honest. He doesn’t con clients on fees and gives a detailed invoice. I recommend Jon Nicholson and had a great experience with great results.

Jon came recommended by a friend. We had a stress-free and extremely fast process when adopting our child. He started working the very first time I called him and kept us in the loop throughout the entire case. He provided phone calls and even step-by-step instructions for me to follow after the adoption to make sure everything went well.
Sara Summers

“Jon Nicholson was incredibly professional and kind as he worked with my ex and I through a tough-but-amiable divorce process. With his knowledge and quite-mannered approach, we were able to work through the issues of property, child custody, etc to a satisfactory conclusion for the both of us. Jon became a strong advocate for our children’s needs and rights during our negotiations and review, which proved to be something my ex and I could both get behind. Quality mediation between the two parties was handled with much professionalism and care. Drama was virtually non-existent. I would recommend his services to anyone, especially if you are seeking a fair, amiable solution to a tough legal situation. Jon is your man.”

We highly recommend him.

With Jon’s help I was able to adopt my foster child. He came highly recommended and I was not disappointed. From the time the papers were filed until the adoption was final was approximately 2 months. He is very professional and knowledgeable. He was available for questions and promptly responded to messages left. His fees are quite responsible. Good job Jon. Thank you.

Jon was amazing to work with on our sons adoption. It was unknown how smooth it could go but after hiring him we felt confident whether it was smooth or not. We really appreciate him and knew he cared about our case. Not only would we recommend him to others, but we will definitely be hiring him again if we ever need to! Thank you Jon Nicholson

Jon was very responsive when ever I called or emailed. He listened to what I wanted and was honest with me if he thought it would work or not. We was on top of getting the other lawyer to file paperwork, or reach out to his client. Having to get a lawyer is never fun, But Jon was professional, understanding, honest, and affordable. If I ever need a family lawyer again, he will be my first call!

We just completed our first of two adoptions. Jon Nicholson came highly recommended from other Foster Parents who have adopted. We were so happy with his professional and uncomplicated way of moving through the process. He answered all our questions before we even had to ask them and guided us every step of the way. It was truly a stress free experience. We highly recommend Jon and are thrilled to use him for any other family law services we may need in the future.

“When I walked into Jon’s office I was lost, I had not seen my kids for several months and I was unsure what to do. Jon knew exactly what to do, we made a plan and the first time in several years I had some hope that I would get to see my kids. Jon knows the law and in court he is masterful. I felt like input was valued and taken into consideration at every step. Jon really cares, and my children and their well being was paramount at every step. I would highly recommend Jon Nicholson for your legal needs. I still send Jon updates on my children 10 years after I gained custody and Jon is always happy to respond with kindness and interest in their well being.”
