Highly Recommend HKP!

I hired Mr. Kienle to defend me in a trust litigation matter. He was courteous and professional, and his depth of expertise in such matters was obvious from the start. His fees were very fair and he did not inflate his charges. The outcome was successful and I would hire HKP again.

Messy Trust issue

When my mother passed in May 2023, her live-in boyfriend of 42 years signed her death certificate as her husband; and that began the fraud as he used that to take my mother's 50% of a Condo they purchased together in 1988 and put it in his Trust. I never wanted to litigate in court, but he was makin...g it difficult and was non- responsive to all our required communication. Eventually, he sued my mother's Trust to say the Condo was all his. Unfortunately, that was never written down, but what was documented legally with my mother's half of the Condo in multiple ways and on her deed. We proved he did not have the right to do that and told him it was Fraud, which he claims he didn't understand how it could be fraud. He used multiple attorneys, so it made discovery complicated. Finally, we provided a way out for him and gave him grace to accept the terms of putting the 50% back, without any further legal trouble. He finally agreed and Andrew Kienle worked through the entire process efficiently and with complete professionalism. I hope I don't need his firm again, but if I did, I would not hesitate to reach out again and work with Mr. Kienle.

Excellent Trust Litigation Attorney

I have worked with many attorneys in various capacities over the years. This was the first time I have ever needed representation. I met with and hired Mr. Kienle to represent me and my father's estate. Mr. Kienle was very knowledgeable in trust law, something that evident throughout the case. He w...ent over and above in his communication with me throughout the entire process. He was very responsive to phone calls and emails. Mr. Kienle was always respectful to the court and well prepared. It was evident this was noticed by the Judge handling the case. If you are ever in the position of needing a trust litigation attorney, I would highly recommend Mr. Kienle.

General Litigation

I hired Andrew Kienle to represent me when my claim to ownership of my house was challenged. I found him to be professional and knowledgeable as he guided me through the long and frustrating process. He was available for questions and explanations and his strategies and insights brought the result...s to a favorable ending. During the process the house was sold before the case was over and Andrew's real estate expertise helped make that very complicated process flow smoothly. I would highly recommend Andrew Kienle and Hart Kienle and Pentecost.
