From debt collecting, to advice and representation at Court or Mediation, we assist our clients with simple clear advice and assistance when a dispute arises.


Personal Injury Claims

If you have suffered a personal injury of any kind and you believe that it could have been prevented if another person or party acted appropriately, then let us know and we can assess the merits of making a claim. Our assessment is usually without fee or obligation.


Power of Attorney & Court of Protection

We guide you through that process, prepare the documents, complete the Solicitor’s certificate for capacity and complete the formal registration process.

Trusts For The Family

If you intend to review your Will or make a gift in excess of £10,000 in value, contact us to arrange an appointment or discussion. Trusts often are the best vehicle to enable you to pass a gift to your chosen beneficiary in a way that is protected for them and against third parties.



There are a number of matters relating to your Wills which many individuals and families do not often appreciate need consideration. Anyone undertaking a Will ought to have advice from us on the options available as well as making sure the Will is carefully and properly prepared and signed off to ensure its legal validity.
