In all fairness to the lawyer putting on the workshop, he spent maybe 5 minutes of 90 minutes going over this. And, I imagine that just about every other estate lawyer would offer something similar since some people want this. Obviously, if you want to make money you offer what people want.
Right now, I'm struggling with what we want with a Trust and whether we need one at all.
I think you shouldn't be just considering shielding assets for Medicaid purposes, but determine whether the trust serves other purposes. We have trusts, but there isn't any Medicaid protection provisions in them because we don't intend to rely on Medicaid for any purposes. Our trusts are designed to make it easier for handing off our estates to a surviving spouse and later children/heirs, and provide for creditor and divorce protection for our children. My MIL created an irrevocable trust in the last few months of her life, but this was primarily designed for a special needs child (my BIL with MS) and to qualify her for VA benefits -- but she passed away before we could even apply for VA benefits for home and attendance benefits as a surviving spouse of a WWII era veteran. And if MIL needed LTC in a skilled nursing facility we were going to private pay for that from our own resources.
Many folks who get on this Medicaid protection, asset sheltering band wagon, have the tail wagging the dog. Determine what type of care you might need, what type of burden you might place on your loved ones, and go from there -- doesn't sound like a good plan to rely on Medicaid coverage as an initial step.
