Dispute Resolution


Guillaume Staal is a Partner at Dickinson Gleeson and an Advocate of the Royal Court of Jersey who joined the firm in April 2012.

Guillaume’s principal areas of expertise include dealing with allegations of breaches of fiduciary duty, contractual disputes, enforcement of foreign judgments and associated freezing and disclosure orders.

Guillaume has been involved in a range of innovative Jersey cases including (1) securing an interim freezing order over a trust in aid of proceedings brought by a non-beneficiary before overcoming the ‘firewall provisions’ of the Trusts (Jersey) Law 1984 to obtain directions in Jersey giving substantial effect to an English order setting aside the trust, giving our client access to assets previously held in that trust to settle her divorce claim; (2) securing one of Jersey’s first statutory Hastings-Bass and mistake cases allowing steps taken within a trust to be unwound to avoid their crippling tax consequences; and (3) establishing that a common intention constructive trust may (as a matter of Jersey law) arise in relation to a loan account to a Jersey company in order to secure our client’s interest in that valuable asset.

A recent highlight has been acting for a Jersey company in relation to potential breach of duty claims against former directors. The matter related to the well-publicised controversial acquisition of a substantial London property by the Secretariat of State of the Holy See (Vatican) and the ongoing investigation into it and related transactions. Questions have been raised in relation to the value paid for the London property by the Vatican, the role of various intermediaries and the substantial sums they derived from their involvement. In Jersey, questions arise as to the conduct of the corporate directors of the Jersey structure and their compliance with their fiduciary duties. Related proceedings are afoot in the UK together with criminal investigations emanating from Italy.

Guillaume is also regularly instructed in relation to probate and employment law matters.

Guillaume is listed as a ‘Next Generation Partner’ in Legal 500 described as “adding very impressive strength to estate disputes”. He is ranked as a Rising Leader in the Private Client Global Elite, featured on the Citywealth Leaders List and previously named as one of eprivateclient’s Top 35 Under 35 – Channel Islands.








Out of the office, Guillaume is kept busy and endlessly entertained by his three young children.
