Absolutely not. The Creator of the trust can and should continue to invest in a variety of different assets to achieve a secure and somewhat diversified portfolio. As the creator continues to buy and sell properties and assets, the trust document itself will never have to be changed. The creator must make sure, however, that title to the new asset is correctly worded so that the asset will be considered trust property, owned by the creator, and would be able to flow through the trust to the ultimate beneficiaries.
