A trust is a legal entity that a person creates. It can be a flexible and useful tool in estate planning and can be designed in a variety of ways. A trust provides financial benefits for people and/or organizations designated in the trust document. The document also provides the details and instructions for the trust. The trust document should be written by a professional who has experience in writing trusts and who is familiar with current trust laws. The tax consequences of trusts should also be considered; trusts do not save money for your estate in all situations.
