A revocable living trust provides financial protection in the event you are no longer able to manage your financial affairs yourself. You can be trustee while you are healthy, but if you have a stroke or become otherwise incapacitated, your successor trustee would manage your assets in the trust.
A will is a legal document that transfers what you own to your beneficiaries upon your death. It also names an executor to carry out the terms of your will and a guardian for your minor children, if you have any.
Your signature and those of two witnesses make your will authentic. Witnesses don't have to know what the will says, but they must watch you sign it and you must watch them witness it.
A Charitable Remainder Trust normally is used as a strategy for converting highly appreciated assets into income producing assets, without income tax liability. The Charitable Remainder Trust is an irrevocable trust with both charitable and non-charitable beneficiaries.
