Hannah was amazing, she always replied quickly to calls or messages, even out of hours. She was very clear offering all available options and factored in my financial position. Her understanding of family law proceedings was evident in how she strategically emphasised the key aspects of my case; explaining where I could gain some transaction. Hannah’s knowledge and ability to present a strong case, as well as allocating a knowledgeable, formidable barrister, was the major factor in achieving a successful outcome in court.

From our first meeting through to this final order I have been extremely impressed by both the highest standards of your personal service and your professional grasp and prompt communications.

I used Hannah Cornish from Keystone for both the financial and child matters in my separation and I cannot recommend her enough. She has guided me through all aspects of these in a matter of fact way, giving me the pros and cons, and which route she thought was best. She never told me what I wanted to hear, but instead what I needed to. Both of my outcomes went in my favour and I have no doubt it was because of Hannah’s expert advice.
