  • Firstly I would like to thank you for the support you have provided through this journey.  Not only did you make us feel safe and secure and in total trust with your professionalism and manner, you also achieved more than what we asked for which was costs payable by police.  We have never had to deal with a matter like this before and I had no idea how to tackle this, we were going in blind.  After hours of googling, something kept making me come back to Williams Lawyers.  Our email was answered in less than 24 hours and after the first phone call an appointment time was made quickly.   As soon as we spoke to you we knew it was right for us and we could let you handle this with ease.  I can’t thank you enough for the professionalism, confidentiality and support you provided, with the best outcome possible – very much appreciated.
