It is very important to pass on with a plan in place. An estate plan can help you ID which family members and loved ones will receive your property after your death. It will ensure that your property will go to those you have identified, as quickly and with as few legal hurdles as possible.
You also would avoid the time and costs associated with the probate process. Going through probate is time consuming and can become expensive (which may drain the estate further).
Further, an Estate Plan can dictate the kinds of life-prolonging medical care you wish to receive should you be unable to make your wishes known when the time comes. Your funeral arrangement preferences are generally also included in the Estate Plan.
Finally, you can minimize the amount of taxes that will need to be paid in order for your property to pass to others after your death by designating beneficiaries for your estate.
