TESTIMONIAL: Raymond Mah is a true professional, he is very knowledgeable and always there to provide timely legal advice whenever required. He is very patient and helpful and has a knack for making complex legal terms and issues easy to understand. It helps that his team is effectively bilingual in English and Mandarin. We are very satisfied with his excellent services (since 2005) and grateful for his help. It has been a great pleasure working with Raymond. We would like to thank him for his dedication, hard work and patience and would strongly recommend him to anyone seeking a good lawyer.

CLIENT: Chong Yee Meng (Honeywell Malaysia)
TESTIMONIAL: “Usually I would contact Richard Wee for ideas on how best to avoid litigation. He has many a time been able to provide me with practical and innovative strategies to help my organization avoid the perils of litigation. It’s crucial in my course of work to have advisors like Richard to help plan and strategize my organization’s business.
For a relatively large firm, MWKA’s team of lawyers are considered accessible (particularly Richard in this case) and they seem to be able to provide their feedback/ opinions within a reasonable turnaround time. Generally, I find other firms to be lacking the personal touch which MWKA offers to its clients.”

CLIENT: Ir. Dr Wong Fook Keong (WEA Engineers & Associates Sdn Bhd)
TESTIMONIAL: I was very pleased with Raymond Mah’s ability to quickly grasp the engineering concepts involved and his attention to detail. The team consisting of Raymond and Gan Chong Chieh was meticulous in its preparation and efficient in its delivery. I appreciated that they always took the time to explain to me the legal aspects of the case and keep me informed of the progress of the case. Working closely together, we won my claim of RM157,000 and successfully defended the counterclaim of RM800,000.

CLIENT: Chan Su-Li (Chevron Malaysia Limited)
TESTIMONIAL: Chevron has high standards and expectations of its selected outside counsel, which includes speedy responses and legal advice that is grounded in commercial reality. Richard Wee and his team of Solicitors at MahWengKwai & Associates have not disappointed in this regard.
We find that Richard and his team are easily accessible and accommodating and that Richard also imposes a fair rate for his professional fees.
I would recommend Richard Wee and his team.

CLIENT: Joseph Tan
TESTIMONIAL: Based on my dealings with Raymond Mah, I am satisfied with the good knowledge of the law; vast experience; excellent analytical skills and ability to have a good grasp of complicated issues; great writing skills in preparing persuasive or compelling representations; quick response time (e.g. update of the day’s Court proceedings emailed to me before day’s end); patience. Raymond is particularly sharp, critical, creative and able to quickly make sense of what appear to be difficult issues. In terms of professionalism and quality or standard of services, I would rate MWKA as for better than many other legal firms of the same size that I know.

TESTIMONIAL: To whom it may concern. Our company PILOT CARGO ( M ) SDN BHD has been using the legal services of MahWengKwai & Associates for quite some time now. We have also been very impressed with their professionalism and level of service. Richard Wee and his team of lawyers have always shown urgency in their work, regardless whether the case is big or small. They are also easily accessible and very accommodating to their client’s needs.
A highly recommendable law firm to use if the need arises !!!

CLIENT: K.K. Ong (Pilecon Engineering Berhad)
TESTIMONIAL: Overall I find their services quite efficient and satisfactory. Whenever we need to meet for a group discussion, it is easy to fix an appointment with the lawyer in charge, even outside normal working hours. Their research and preparatory work is up to date, as evidenced by the successful litigation results so far. As for their professional fees, I find them reasonable and comparable to some of the other legal firms. The standard set by the founding partners appears to have been retained. Should a new litigation matter arise, MahWengKwai & Assoc. will be one of our 3 top choices.

CLIENT: KK Chong (BBT Solutions Sdn Bhd)
TESTIMONIAL: We at BBT Solutions Sdn Bhd had engaged Richard Wee and his team from MahWengKwai & Associates (MWKA) for a few legal matters, namely litigation, company issues and matters in relation to real estate.
We are satisfied with their professionalism when dealing with each and every matter that was brought to them. They work in a timely manner and give us a sound legal opinion when requested, for us to make our commercial decision.
For us, we would put a recommendation to engage Richard Wee and his team at MWKA as they had given us an exceptional and quality service at all time.

TESTIMONIAL: Dear Mr Raymond Mah & Ms Chloe Lim
“I am writing to express my thanks and appreciation for handling a difficult case that was causing me a great deal of stress. Both of you did an excellent job in spite of the complexities and very tedious nature of this case. I am especially appreciative of the admirable work culture and ethics of the firm. All communication was promptly responded to and great care was taken to ensure that possible trouble was avoided. Not only are you both very professional and knowledgeable lawyers but are very pleasant and helpful too. I have no hesitation in recommending the both of you to any clients who require legal representation.”
