Absolutely. You can set the funds aside now and choose your funeral home at a later date. Funds are typically paid to the funeral home within two business days.
The funds are held by an licensed escrow agent that is licensed in your state. It is a combination of Irrevocable funeral trust and the strength of an 110 year old insurance company. There is no cost for the Trust!
Your final expense trust can be transferred or directed to any other funeral home of your choice. In town, out of town, out of state. It's portable. It goes with you. You own it, and you have control of these funds.
You can always make changes to your final wishes. You may decide that you prefer a different type of service, or you could cancel them completely. But then you would be back to beginning with no plan.
