What must happen if there are amendments to the prearrangement funeral service trust agreement?

When there are amendments to a prearrangement funeral service trust agreement, it is essential that these changes receive approval from the appropriate regulatory board before being incorporated into the existing agreement. This requirement ensures that the amendments adhere to applicable laws and regulations, maintaining the integrity of the funeral service offering and protecting the interests of the trust's beneficiaries.

Approval from the board acts as a safeguard, ensuring that any modifications made to the trust agreement align with established standards and provide for the proper administration of the funds involved. This process promotes transparency and accountability, which are critical in maintaining public trust in funeral service practices.

The other options suggest various scenarios that do not align with the regulatory framework established for funeral service trusts. For instance, making amendments without approval could lead to inconsistencies and violate regulatory requirements. Similarly, while communicating amendments to purchasers and filing them with a county office might be important for transparency and local regulation, they do not replace the need for prior approval from the board.
