A Will is a document you create which states who will inherit your property after you die, who the executor will be, and who the guardians of your minor children will be.
If your assets pass to your family through your Will, they will need to go through Probate first.
Even if you create a Family Trust to avoid probate when you die, you will still need to create a “pour-over Will,” which provides that any assets you did not transfer into your family trust before your death are to be transferred into your family trust at your death. These assets will, however, need to be probated before they are transferred into the family trust. You do not want to rely on a pour-over Will to transfer assets into your family trust at your death; instead, you should make sure that your assets are in the trust before you die.
