Absolutely not! The creator of the trust can and should continue to invest his or her money and assets to achieve a secure and diversified portfolio. No matter how many properties or assets the creator buys or sells, the trust document itself will not need to be changed. The creator MUST make sure, however, that the title of the new asset (be it a house, for example), is worded correctly so that the new property will be considered official “trust property”, owned by the creator, and able to be distributed to said beneficiaries.
