Mr. Mubasher took the time out to discuss my case in regards to a default judgement. He gave me great legal tips to help me go forward with the case and gave me the confidence I needed to go to court and try to get the judgement vacated. He also offered to help me in anyway he could and followed up w...ith an email.

It was my pleasure to consult you!

Posted by anonymous | March 19, 2019 | Hired Attorney | Ethics & Professional Responsibility

Nathan Mubasher Failed Me.

Communications with Nathan were through telecommunications. Nathan seemed like a respectable attorney at first. First case Nathan handled had to do with a previous attorney regarding legal malpractice/ negligence in Jan ‘15. Ironically, the following happened; In May ‘16 Nathan violated rule 3-120 fo...llowed by charging me tens of thousands of dollars. Nathan sent me mixed signals while handling legal matters for me. Therapy/ legal counsel was obtained in order to understand most of what Nathan did to me. I still do not understand why. I never expected to befall such an experience because I trusted Nathan wholeheartedly. Under Nathan's professional negligence I suffered a lot emotionally unnecessarily. I cannot recommend this attorney because Nathan failed to protect me. As a client, I didn't need to be further harmed by the one person I should have been able to trust. I also learned that Nathan crafted a retainer agreement that is in direct opposition to what is required by the Business and Professions Code 6148, subd. (a)(2), (3). Nathan rather skillfully writes an agreement in order to take thousands of dollars without even as much as setting foot into a court room, as per his third agreement with me stated that I would pay him 5 K up front with 2 K per month up to a "CMC", which I was informed that trial dates may not even be set by that point. Nathan made no appearances, and hardly did anything for a period of 8 months while the case was "active" and took nearly twenty-two grand for this alone. Nathan never finished the only case he took on to litigate, causing my case to be in danger due to SOL. No client should go through what I did, and no lawyer should harm their client the way Nathan harmed me. I’ve never been diagnosed with Asperger’s by anyone other than Nathan, ultimately confusing me. Nathan isn’t qualified to offer medical diagnosis’s and did so to trick and confuse me. Nathan had; my medical file, doctor’s diagnosis of my PTSD, severe social, intimacy anxiety, various phobias. I wonder why approx. 16 months into a professional client/ attorney relationship; Nathan willfully called me on the phone expressing his passionate desire to be in a romantic relationship with me. I awkwardly explained to Nathan why it wouldn’t work, Nathan stated he’d “do anything to accommodate my anxieties during romantic dates” Nathan in the guise of professional business, calls me to suddenly bring up romance, causing me anxiety. I feared answering his calls. Nathan called one evening, conversation began as business, Nathan then began talking about me having his baby. I asked Nathan to put a hold on his romantic interest in me to enable me to focus on my wellbeing and legal issues but Nathan disagreed. I contemplated suicide. I felt trapped. Nathan coached me to author specifically written reviews which I took down. The paraphrased one in Nathan’s forever changing responses below is a prime example. Nathan told me to use different computers. I told him I only owned one computer and would feel extremely uncomfortable writing coached reviews just to artificially raise his ratings. I confronted Nathan; Nathan would claim that I “didn’t love him” was “playing games” and that my love was “fleeting”. It would cause me severe anxiety and confusion. Nathan never fired me. I politely declined Nathan’s last contract to his disappointment. Nathan became enraged. Nathan responded that I was on my own to handle all legal matters. I bravely wrote my first genuine review of Nathan in Dec/ 2017. Nathan emailed me claiming he wanted to “urgently” talk to me. Obvious reasons, I ignored his controlling email. Nathan was served my lawsuit by a professional server days later. He became enraged and later that day, Nathan called his officer friend from the Corona, CA. PD and his friend harassed me on false allegations, threatening to abduct and arrest me if I didn’t take my review of Nathan down.

I have never met this client in person but was very patient with her. After representing her professionally on multiple legal matters, she unfortunately began experiencing erotic transference, and began engaging in unwanted sexual harassment with 100's of emails and voicemails. (Erotic transference is characterized by repetitive and compulsive demands that when not met, can convert into hatred). I professionally advised her to seek therapy so as to not jeopardize her case, and she attempted to do so but the therapy failed. She kept promising to respect the professional relationship but then would repeat her patterns of behavior. I was radically patient with this client but then fired her after becoming concerned for my own safety as this client's transference finally escalated to her telling me she wanted to leave her husband and have my baby, despite never even having met me, and then sending me poetry with suggestive firearm violence imagery. After I fired and blocked them, the client then deleted the 5-star review they gave me 3 months earlier on 8/25/17. THE ORIGINAL 5-STAR REVIEW: Title of review: Mr. Nathan Mubasher - Expert of the highest caliber. Body of review: I hired Mr. Mubasher several times and experienced the highest quality of care. Nathan showed me exactly what it was to experience the greatest of care, compassion, reliability and unquestionable ethics adhering to the optimum in sentinel with my cases and I definitely could not have asked for anyone better, as Mr. Mubasher in my eyes, was and is; simply the best there ever will be in legal history and future. I felt so safe in his legal care and his wonderful qualities exceeded every single one of my expectations, so much so, that I had to ask myself, does this brilliant lawyer hold a Doctor of Juridical Science? (Which, by the way, is the highest degree a lawyer can hold) Because, it certainly seems like he does with his meticulous and dedicated nature. Mr. Mubasher was always timely, always there for me, always took the time to explain the process, such a professional lawyer, I couldn't believe just how lucky I truly was for having him as my attorney when I needed him the most. Mr. Mubasher would promptly answer my calls within a reasonable amount of time, sometimes within minutes, I always felt like I had an open line of communication with him, whether it be via email, or telephone, like a legal guardian angel. Mr. Mubasher never once gave up on obtaining justice for me, and that's exactly what anyone deserves and should expect out of a lawyer, and I certainly got that with him. I highly recommend Mr. Mubasher for his excellence in service, for his wonderful nature, his compassion, his care, his intelligence, his methods. Absolutely everything about Mr. Mubasher is exactly what every attorney should epitomize, Mr. Mubasher sets the standards for what an attorney should stand for. Just looking at his academic achievements, his awards; are stunning to behold and shows what a brilliant shining diamond I had the respectful honor to work with. I am forever grateful for having had Mr. Mubasher is my life, and I will forever have Mr. Mubasher in my heart and prayers. Mr. Mubasher was truly patient with me as I have Asperger's syndrome but never once did Mr. Mubasher make me feel any different for it and always treated me with the utmost in care. Mr. Mubasher- Thank you so very much and I wish you the greatest life has to offer you. Overall Rating 5
