Benjamin Franklin once said that "in this world nothing can be said to be certain except death and taxes". Unfortunately I can't help you avoid either but I can help you to plan to take care of your family and friends after your death and minimise the tax burden your estate may otherwise face.
The creation of a Will ensures that your spouse or partner is provided for in the way you intend and any children are cared for by individuals chosen by you whilst being financially taken care of in the most tax efficient way.
