There are certain situations in which a trust will be important and useful to you. In the case where you are likely to become incapacitated in your lifetime and you are no longer able to manage your assets and affairs, there will already be a trust in place where you would have named a trustee to manage your properties. It can offer you great peace of mind when you do not have to be declared incompetent since you already have a person you trust in place to make the decisions for you.
If it is your will to have your assets distributed immediately after your death and without any interference a trust is your best option. A trust will help ensure that your bank accounts are not frozen after death and that there is no interruption in ownership and management of property.
Also, one of the times that it will highly favor your situation to have a trust is if you feel that after your death your property or assets may become contested after death occurs. If your plan is to disinherit a spouse or a child a trust will allow for those wishes to be fulfilled without the interference of the court. Doing this through a will can lead to the will being overturned after a lengthy court battle. However, you should note that the rules vary depending on the state.
