The will while alive (“levenstestament”) is a special form of a will. In a will you determine what should happen after your death with your legacy. A will therefore does not apply until you pass away, while a will while alive applies for situations in your life. For example, in case you are unable to act due to illness or an accident, you can designate someone to whom you are confident to represent your interests in a will while alive. This way you keep in control and things are done according to your wishes.
Besides financial issues, a will while alive might also involve medical decisions (treatment or no treatment) or what should happen to your home if you could not live there independently anymore. You can also record personal wishes, for example about your care or the care of your pets.
