When you make a will, you can say how your funeral should be dealt with, and what will happen to your possessions and assets when you die. If you die without making a will (called 'dying intestate'), it can be complicated to work out who will get what.
The Administration of Estates Act 1925 sets out who can apply to deal with your affairs if you die intestate (called 'administering the estate') and how your belongings are to be shared. But several people may have an equal right to do this (for example, your children). The usual rule for appointing administrators is 'first- come, first- served'. However, without a will, there may be dispute or uncertainty.
