Wills & Estate Planning

Wills & estate planning are essentially about the living. That may seem contradictory, but we believe that while dealing with the estates of the deceased, we are very much working with those left behind. We can help you organise and plan your affairs, and protect and preserve your own interests and those of your family, both now and in the future, by advising on inheritance issues, your wills and estate planning and offering guidance on the duties, rights and obligations of trustees, executors or beneficiaries.

Guardianship, Delegates and Powers of Attorney

Depending upon your jurisdiction, guardianship, delegates and powers of attorney are useful tools in helping a party to deal with the financial affairs of another, whether that is paying bills, managing bank accounts or otherwise. Whether you are choosing to give someone power to deal with your affairs, or you have a relative who can't deal with their own any longer, careful consideration needs to be given, and advice sought, to decide what route is most appropriate.

Wills, Probate & Succession

Managing wealth, asset preservation, planning for succession and inheritance, and writing wills can be a complex and difficult experience. It's important to ensure that your assets are distributed according to your wishes and your family and successor's lifestyles are maintained. Alternatively, there may be other ways that you wish to dispose of your estate, for charitable and philanthropic reasons or to look after those who are unable to care for themselves. Whatever you choose, it is important to seek the right advice to ensure your wishes are preserved. At Collas Crill we have experts in a number of jurisdictions to assist with wills, succession planning, inheritance matters and probate.

Probate & Estate Administration

When executors, family or friends of a deceased need to get access to assets held by their loved one, they may be asked to produce a document commonly referred to as a 'grant of probate'. This can be an unfamiliar and stressful process. At Collas Crill we have many years' experience in making these types of applications. We are able to assist in simply obtaining the grant of probate, can arrange release and payment of the Channel Island assets to the relevant person, or deal with the full administration of an estate depending on your requirements.
