A Will is a legal document that provides guidance for your loved ones regarding the distribution of your estate and who will assist in completing the distribution (Executors). It can also cover certain gifts made to loved ones, who looks after any children and anything else you think is important for your Executors to know.
It is important that your loved ones have clear instructions on how you would like your Estate divided up. This will reduce the potential for people contesting the Estate and make the process of administering the Estate easier on your Executors. An Estate distribution with a Will is much more likely to have less legal expenses than an Estate without a Will.
