Key Experience

  • Acted for the ultimate administrator of an estate whereby the deceased – shortly before dying of end-stage dementia – had been approached in a care home by a conman, who had forged a Will and Power of Attorney, and had gone on to take out a Grant of Probate and attempt to strip the estate of all assets. This attempt was cut short, with the conman's Grant of Probate revoked, the transfer of a valuable London property prevented, and the rightful administrator put in place to administer the estate on behalf of the family.
  • Acted for a beneficiary of an UHNW multi-jurisdictional trust in proceedings brought in New Zealand by the trustee due to unprecedented geo-political circumstances.
  • Acted for a high profile client in respect of a dispute with a family member over the nature of a significant payment of tens of millions of pounds made in connection with a UK property purchase.
  • Acted for an executor/trustee of a high-value estate with assets around the world, with proceedings starting in England, before then being brought in Russia.
  • Acted for an aristocratic client of a prominent landed estate, in various aspects of a dispute involving the client's (and wider family's) trusts and the client's own succession issues including the passing of aristocratic title to the next generation.
  • Acted for a HNW beneficiary of a Guernsey trust, successfully removing the trustee, before assisting the new trustee in making enquiries as to specific transactions which required investigation.
