Shân’s practice involves all aspects of trusts and estates, both contentious and non-contentious. She is equally at home advising on wealth structuring for clients around the world or on cooperative variations of trust as she is in hotly-contested trust disputes.

She appeared in Re Yorke (deceased)  4 All ER. 907, the test case on estates of Lloyds Names, and is the author of the subsequent Practice Direction permitting paper applications to the court in such cases.
