do you need to update your will, poa's,Living Wills when you move to another state? We have changed our permanent address from N.Dakota to Colorado

They usually are fine, but it's hard to say without seeing the actual documents. The biggest issue with a relocation for most people is if you still own property in the other state (or another state in general), as you can end up having to open probate in multiple states in that case, and you'd want to do some planning to avoid this (like using a trust). I hope this helps.
