Either a will or a trust may be appropriate for your estate depending on your circumstances and neither is best for all situations.
Which do you need more, a will or a trust? Or do you need both? Well, the answer really varies by person.
Forbes recently considered this question in an article titled "Wills vs. Trusts: What's Best For Retirees?"
There's really no reason not to have a will. A will is a testament that states your intentions as to how you would like your estate distributed after you pass. A will is a great idea to save your friends and loved ones much frustration and anxiety during the probate process.
A trust is, in essence, setting aside a gift (of property, investments, or money) for the benefit of another with some strings attached: you will name a trustee to care for the trust property for the beneficiary. For example, a trustee may be charged with holding the trust funds until the beneficiary reaches the age of 21, or the funds may only be used for education.
Speaking with an experienced estate planning attorney will help you determine how to set up your will and whether you might need to create a trust.
