Miss. Code Ann. § 75-63-63

Preneed contracts entered into in this state shall be portable. The naming of a substitute provider shall be in writing by the contract beneficiary or by one who is authorized by law to act on their behalf. If the preneed contract is funded by trust, the notice of a substitute provider shall be made to the original preneed contract seller and the trustee holding funds for the beneficiary. Upon receipt of the notice of substitute provider, the original provider shall be relieved of all obligations to perform the contract including all obligations of reporting and accounting. If the preneed contract is funded by insurance, the change of beneficiary shall be made in writing to the insurance company. If for any reason insurance proceeds are paid to a preneed seller who did not furnish the final needs of the beneficiary at their time of need, the policy proceeds shall be paid in full to the substitute provider or the estate of the preneed beneficiary within ten (10) days of receipt.
