I want to give my sincere thanks to Oya Suleyman of EBR Attridge for the incredible work she has done on my behalf. From the very beginning, her professionalism, dedication, and attention to detail have been second to none. She has consistently shown her commitment to protecting me and defending my innocence, and that level of support has given me real peace of mind throughout the process. I truly wouldn’t choose any other solicitor, nor would I trust anyone else to take on such an important responsibility. I am deeply grateful for the way she has handled my case and for the outstanding service she has provided through EBR Attridge.

Sincerely,R.O.S

Oya represented me for just under four years. From police interview to me being sentenced. Throughout this time she was a stalwart of support. The legal advice of course was great but, it was the personal support she offered that really stood out.She found the best of expert witnesses and more importantly guided my family through character witness statements. Unfortunately, we lost our barrister of choice due to scheduling conflicts. Oya spent far more time than is reasonable finding a replacement that I was comfortable with representing me. Oya fought diligently and hard for me with great empathy and I can't recommend her highly enough.

I found Oya very easy to work with, a good listener, also has a great wealth of knowledge. A vast understanding of the law with good advice. Very respectful towards myself and showed empathy in my families situation. I highly recommend.

I had the privilege of working with Oya during a very challenging time, and I cannot overstate the impact of her professionalism and support. From the very beginning, Oya approached my case with exceptional care and empathy, making me feel heard and understood at every stage. She dedicated the time to go through every detail of my case with me, ensuring that I was fully prepared and that nothing was overlooked. 

 What stood out to me the most was her patience and understanding. My English is not the best, but Oya never made me feel rushed or misunderstood. She explained the complexities of court proceedings with patience and clarity, and her professional guidance gave me confidence at each stage. In the lead-up to trial, her calm reassurance and strategic advice were invaluable, and I always felt she was fully invested in achieving the best possible outcome.

Oya is not only an outstanding lawyer, but also someone who approaches her work with kindness, patience, and integrity. I am truly grateful for her dedication and would recommend her without hesitation. 

Mr. GSR. 

  I recently worked closely with Oya as she represented my dad in his criminal case, and I can confidently say she was outstanding. Throughout the process, I often translated and completed court documents for my dad, and Oya always made sure I was kept up to date on every stage of the case and each hearing leading up to the trial. She explained legal issues in a clear, approachable way and gave thoughtful advice on how best to proceed at every step.

 During the trial itself, her focus and preparation were remarkable. She was always on top of what was happening in court, and she took the time to explain her concerns and recommendations, including the crucial decision regarding whether my dad should take the stand. Thanks to her professional guidance, we made the right choice, and it ultimately benefitted my dad’s case. 

 I am deeply grateful for her expertise and support. Oya is someone who truly cares about her clients and their families, and I would highly recommend her to anyone in need of a skilled and dedicated criminal defence lawyer. 

Miss. SR

 I cannot thank Oya enough for the incredible work they did on my husband’s case. From the very beginning, they were professional, supportive, and always kept us fully informed. They worked tirelessly to make sure every detail was covered, and their knowledge and expertise were outstanding. Thanks to their dedication, my husband was found innocent, and we can now move forward with peace of mind. I would highly recommend Oya to anyone in need of a solicitor who genuinely cares and will fight for the best outcome.

Mr and Mrs RC.

 "I have found the practice of Ebrattridge to be efficient and friendly.  Oya Suleyman has represented my son, who has learning difficulties, on a number of occasions. She has shown compassion and consideration to him, whilst ensuring that he understood the implications of his actions.  She is far from the uncaring ‘person in the suit’,  she is professional, intuitive and effective.  I was impressed with her knowledge and commitment to not leave a leaf unturned, in her dedicated pursuance of his defence. Ms Suleyman breaks the boundaries of the hard face of the law, and is able to relate to the person to obtain the best outcome for them.  She has sound ethics and balances the crime with both circumstances and interests of the wider society.  She is the epitome of what a good lawyer should be and it was a privilege to have her defend my son"  (L)

"I have been represented by Oya Suleyman of EBR Attridge since June 2015 and am still being represented by her.  I would like to say that without her by my side throughout my case I truly don’t think I could have got through it, the advice and the amount of hard work she put into helping me and is still helping is first class. A member of my family is also currently being represented by her and they too would also like to echo the same praise and gratitude towards Oya for her on going work".

 “Thank you for your support and motivation. I’m grateful to have you as a solicitor” AY

 “Oya has been fantastic throughout the case, she has always been helpful and informative when I had any questions, or things I didn’t understand.  I could not have asked for a better legal representative – well done and thanks” AP
