To die intestate (without having made a Will) leaves your loved ones in an uncertain and stressful position. Putting your affairs in order is one of the most important tasks you are ever likely to undertake.
Married Couples: Without a Will it is not certain that your spouse will directly inherit your assets, unless they are jointly owned. Do not assume that your assets are jointly owned - this is not always the case.
Unmarried Couples: without a Will your partner may not receive anything! Your entire estate will probably be divided between your children; if you don't have any children then your assets will be shared between your relatives.
Divorced or Separated: Without a Will your former spouse could be entitled to claim a part of your assets!
Parents of young children: By making a Will you can ensure that the courts are aware of who you wish to care for your children in the event of your death.
