Both documents have their pros and cons. The main difference is that your will won’t kick in until your death. A trust, on the other hand, goes into effect as soon as it’s created. If you’re incapacitated, your trustee can assume control of your estate. Wills go through a probate process; a trust does not, which can save time and money. A will lets you appoint a guardian for your kids. A trust does not. A trust can save money on taxes and is private. A will, and any transactions resulting from it, are public record.
