Background and experience

Heidi is an advocate of the Royal Court of Guernsey. She joined Ogier in 2020 and has extensive experience dealing with contentious trusts, acting in administrative applications and hostile trust proceedings. She regularly acts for trustees, beneficiaries, high‑net‑worth individuals and professional advisors. Her work in this area spans contested Public Trustee v Cooper applications, sham trust allegations, rectification and variation proceedings, and disputes concerning the removal of trustees. She also advises on issues arising from tax compliance failures, information requests and cross‑border questions of capacity, legitimacy and estate administration.

Heidi’s practice also encompasses shareholder disputes, professional negligence claims, insolvency and tax disclosure requests emanating from various jurisdictions. She has acted in a wide range of international tax and regulatory matters, including:

• responding to disclosure requests under information‑exchange frameworks

• advising on blessing applications relating to the payment of foreign taxes

• assisting trustees and beneficiaries facing enquiries from tax authorities outside formal agreements

Heidi's regulatory experience includes acting for trustees in GFSC investigations and representing financial institutions in matters involving the Economic Crime Division and proceedings brought under proceeds of crime legislation. Notably, she acted for the taxpayer in the first Guernsey challenge to the Royal Court by way of judicial review.

Heidi's commercial litigation experience includes acting for administrators and liquidators pursuing professional negligence claims against former auditors and directors, advising funds and institutional lenders on negligence actions against service providers, and representing minority shareholders in unfair prejudice proceedings. She also has experience with freezing orders, disclosure obligations and contentious issues arising in the winding‑up of companies. Heidi frequently advises on regulatory matters and cases involving proceeds of crime and anti‑money laundering legislation, often coordinating with advisors across multiple jurisdictions. She also has experience dealing with enforcement proceedings and costs issues, including taxation.

Heidi is a committee member of the Guernsey Bar Council and sits on the Royal Court civil rules committee. She is also an active member of Ogier’s CSR and DEI committee and is particularly supportive of causes focused on social mobility and the representation of women.

Heidi graduated with a 2.1 BA Honours History degree from the University of Leeds. She completed her PGDL and LPC at the Chester College of Law and holds a Diploma from the University of Caen, France.
