Hire Mr. Sims- you won't regret it!
In 2014 Mr. Sims helped us to settle our father's Florida estate. He did it in a timely manner, from a long distance, patiently answering questions along the way and because of the circumstances of our father's death, he was able to direct us to someone who helped to significantly increase the value of our inheritance. Even though I have never met Mr. Sims personally, I can recommend him with confidence should you find you have need for an excellent estate lawyer in the future.

Probate of my mother's estate
I hired Mr. Sims to help with the probate of my mother's estate. His expertise really helped to move my case along in a timely matter. He was always quickly responsive to my emails and questions and kept me informed of where we were in the process so that I was never left wondering what was next. It is clear he knows the laws well surrounding probate and he was detailed and thorough. He was hugely helpful to me by not only finding an attorney in South Carolina, but continuing to correspond with him throughout the process. I had an ancillary probate in SC because my mother owned some property there. I felt confident in his care. And his manner is always warm and welcoming. I was never made to feel like I was a bother to him. I would recommend Mr. Sims to anyone needing help with the probation of their estate. I have the utmost regard and respect for him. He is both smart and kind and extremely knowledgeable in his field. I have no hesitation recommending Mr. Sims to anyone!
