Acceleration Law and Legal Definition
In law, acceleration refers to the speeding up the time of vesting (absolute ownership) of an interest in an estate because the interest in front of it is terminated earlier than expected. In other words there is hastening or a shortening of the time because of the happening of an unexpected event. A person who has the right to take possession of property at some future time may have that right accelerated if the present holder loses his or her legal right to the property. For example if a life estate to B fails due to his untimely death, the remainder is accelerated.
