Probate gives your executor the authority to share your estate according to the instructions you have provided in your will. There is a lot of advice available, a good starting point is the government's website.
However, probate can often seem daunting, especially at such a sensitive time when your family will be grieving. If the executor is a family member, they may feel overwhelmed by the process; they may see it as complicated, or they may not have the time to deal with everything that is required.
This is where solicitors or professional executors can help: the same Will storage facility where my clients can store their Wills can provide caring, sympathetic support for the executor(s); they can carry out many of the initial responsibilities on their behalf, and their company solicitors will manage the official procedures at a preferential rate.
Many clients have asked me to act on their behalf as Executor. This is simply not a service I provide but I am happy to refer professional Executors. Ask me!
