Leaving a Will is especially important if you are a parent. If your children are under the age of 18, you need to make provision for their care should you no longer be there to look after them. A guardian needs to be appointed and instructions left for that guardian as to how your estate should be administered in order to benefit and provide for your children in the best way possible.
Will forms and kits available in newsagencies and stationers have their place, but unless the form is completed and witnessed correctly, it can often be as bad as leaving no Will, especially if nobody knows where to find it...
Drafting your own Will is better than leaving no Will at all, however you should be aware that the laws of probate can be very complex and challenges can be made to the wishes you have set down for your estate. Having a solicitor prepare your Will helps to protect your estate.
