She has a doctor’s note from 2018 and then registered her cat/got a certificate for it this year with the ESA registry.

Jeremy,first let me say how sorry I am for you and your family about your impeding loss.My went through it myself with my Dad two years ago and know how it feels.Now down to business before it gets to late.First,get a lawyer and help your father in law and his family get ready for the transition.Doing it now will save a ton of heartaches and misery later.He needs a will and living trust to spell out exactly who gets what and how much.It will save time and trouble getting the assets transferred to the heirs with minimal hassle and costs and help ease your father in laws mind.Second,get a Power Of Attorney set up now before his mind is declared by his doctor and lawyers to be legally incompetent(I wish I had done this!).
