Just some of Katerina’s reviews

Professional, caring & logical

Ayse

My husband was accused of a crime he didn’t commit and the previous law firm we used were useless. After searching online I came across MK Law and spoke to Katerina Iwai, who is fantastic. She listened and took my husband’s instructions and was always on hand and willing to talk even if we had silly questions. She made us feel calm and we put our trust in her. She appointed an amazing Barrister who wholeheartedly defended my husband and after trial we came out of the court room in floods of tears and overjoyed at being acquitted. This was the best outcome and the highlight of our year so far. I highly recommend MK Law and would also highly recommend Katerina – she is professional, caring and very logical in her thinking. You will be in safe hands with her.

Very happy with MK LAW but particularly Katerina Iwai who was my case worker. She was really easy to communicate with and kept me updated on all of the processes throughout.

Hopefully I won’t have to use them again but I would definitely recommend that if you have a matter of criminal law use MK LAW SOLICITORS

A job well done, Thank you MK Law
MK Law represented by autistic son in a case which the prosecution were determined to pursue in that riding an e-scooter whilst on a driving ban, we challenged this case for nearly nine months and its thanks to the hard work of Kat (paralegal) and David Prosser that the case was eventually thrown out by the prosecution on the basis of defence representations prepared by Kat. It was wonderful in that we were trying to obtain a medical report through the Dr surgery with no success and Kat managed to arrange this and submit to the court and get a positive outcome.

Some of Katerina’s notable cases

Our client had originally been charged with three counts of fraud relating to the fraudulent application of COVID-related Bounce Back Loans, totalling £130k.
The Prosecution initially sought to recover £347,000, including tainted gifts.

However, through detailed representations drafted by Katerina Iwai and a successful challenge by Ini Udom and Georgina Lane of 5 St Andrew’s Hill to the Prosecution’s case the defence secured a significant reduction.

The final available amount was agreed at £1, reflecting a fair and proportionate outcome for our client.

After sentencing, the court assessed that the benefit from criminal conduct amounted to £154,753.88. On instruction from our client Katerina submitted an application to challenge this figure, presenting arguments on a number of criteria

The judge accepted submissions by Katerina working with Bartholomew O’Toole from 5 King’s Bench Walk , resulting in a revised benefit figure of £80,548.85 — almost a 50% reduction.

Our client had been accused of intimidating a complainant in a sensitive assault case involving a family member. The case was built on witness testimony, circumstantial evidence, and mobile phone data — and involved live evidence from co-defendants and the complainant.

After just a few hours of jury deliberation, our client was acquitted on all counts with unanimous not guilty verdicts.
