We each have revocable living trusts (RLT), because we figured even with a 4-figure bill, it was at the time a one-time expense of 0.2% of our NW (as opposed to, say a percentage of AUM yearly), and part of that was for the more standard wills, POAs, living wills, etc.
First off, a lot of the specifics depend on your state, and if you move in retirement, you may need to reevaluate based on your new state of residence, and how it handles inheritance. From what I understand, though, a RLT is pretty irrelevant if you have no real estate or
your state allows POD/TOD on deeds and all your accounts, and car titles, too. Basically, RLTs are useful for assets that would otherwise be probated. For example, my dad rented an apartment, and in NYS there is a household exemption and an exemption for a primary vehicle, so nothing was probated. His retirement accounts were all POD/TOD to me, and other than those, he only kept enough in checking to pay bills, so it was under the exemption.
If you don't think you need a trust, I would recommend seeing a lawyer about a will, or at least doing research on your state and how well wills done from forms hold up. For just a will, it shouldn't be too expensive, and IMO it would be worth the peace of mind to know that the will was as thorough as it needed to be.
