I had the opportunity to work with Insley Ettienne on a complex probate matter involving a leasehold property with no identified next of kin. Insley took the lead on the entire process... She demonstrated clarity, initiative, and sound professional judgement throughout. It was clear that Insley was driving the resolution forward, balancing risk and time sensitivity with confidence and expertise. Her leadership and ability to navigate complex legal frameworks made a significant impact on the outcome of the case. A trusted and highly capable professional, I would welcome the opportunity to work with her again on any high-stakes or sensitive matter.

In the voice of our valued clients lie the testament to Cosil Solution’s commitment to transformative care.
I worked with Insley at Wandle Housing Association. I found Insley to be highly professional was a vast knowledge of leasehold tenures. I have found Insley to be solution-focused with a high-level of customer care; I found her to be very supportive as a colleague and would welcome the opportunity to work with her again.
I worked with Insley at Family Mosaic and found her to be very knowledgeable and passionate in all aspects of her role. Insley is a professional and delivered her services deligently and efficiently.
I am so grateful for Cosil Solutions support in handling my property dispute in a quick and professional manner. They were supportive, friendly, and remained unbiased throughout the whole process. I would not hesitate to use them in the future and highly recommend them.
Having worked with Insley at Family Mosaic as well as another large housing association, I am able to say that she is far one of the most knowledgeable individuals I have worked with in the field. She taught me a great deal about the sector, property management, and various issues surrounding property law. It has always always been a pleasure working with Insley. I would not hesitate in recommending her expertise to any housing organisation.
