Legal 500 Editorial commentary
Testimonials
Collated independently by Legal 500 research team.
- 'This was our company's first transaction on Guernsey and it was highly complex - there was no issue the CO team couldn't overcome or action swiftly in order to keep the wheels moving. From start to finish, a first class service all round.'
- 'Rachel Jones and Davey Le Marquand were our primary advisors, but the whole team was on hand when needed. Fantastic attention to detail at all times, but what stood out in particular was their ability to problem solve and overcome what I understand was a first deal of its kind on the island.'
- 'The team is very thorough and efficient, they turn requests around very quickly.'
- 'Partners are always available if their input is required.'
- 'The property team at Carey Olsen offers a personal approach and shows a genuine desire to achieve the client's goals. Their depth of knowledge is unparalleled in the local commercial property sector, and that is reflected in the efficiency of negotiations.'
- 'I have dealt with Kieran Ogilvie on three occasions, each in relation to commercial property leases. We have been able to successfully negotiate a balanced lease whilst also being granted specific tenants requirements, such as landlord capital contributions, capped property expenses and lease extensions.'
