Conditional will is one which depends upon the occurrence or non occurrence of some uncertain event. It takes effect or may be defeated on the happening of the condition stipulated. If the happening of an event stated in a will is the reason for making the will, it is unconditional. But if the testator intends to dispose of his/her property in case the event happens, the will is conditional. A conditional will can be an attested will, a holographic will or a nuncupative will.
