My mother is in an assisted living facility near my home. Several people have suggested that I make prearrangements for her funeral. I have read pros and cons about this. Does anyone have any experience with this?

yes, I had pre-arrangements for my mother and have done the same for my father and my husband & myself. It is too emotional and exhausting to wait to figure it out at the time death arrives. I strongly say, prepare it in advance --you'll be amazed at how much additional items you will need to think about when the time comes. And if your funeral director is good, they help with everything when the time arrives and you can concentrate on your family and your grief. Linda in FLA.

I forgot to say that one of my Aunts is a widow with no children. Years ago, she made pre-burial arrangements, made my oldest cousin the POA. I think pre-arrangements are a good idea, less stress later on.
Continue checking this site, the care givers are so insightful and do some research on your on.
Best wishes to you.

Since you know that eventually she will be cremated, investing in a niche sound like a good idea. This kind of answered the question for myself as I've just cashed out one of my mom and dad's life ins policys for medicaid purposes. Still wondering about the pre-paid burial/cremation process, these 2 policies weren't valued at very much, $1,700.00 and $700.00.

...ooops...that should read, "NOT too fond of prepayment plans....."

My mom's insurance person talked her into one of those "burial" plans. It was low cost, $40./mo., so she agreed. The problem was she paid for years and accrued very little value in the policy. I had her cash it out...she made a little more than her investment.
You also have to consider if the business will honor it's commitment or what if it changes hands? I am too fond of prepayment plans in general because there are too many variables.
However, if the business has been around a long time and has a good reputation, you may want to consider it. I suppose prices will only go up.
