In the case of a not-so-obvious need, such as Post Traumatic Stress, you are allowed to ask for proof of prescription.

@J Scott you alluded to a prescription but it might help if we knew what kind of access the old house had?

  - there was never any hostile situation, it was allowed by then-seller- if it had NOT been allowed / permitted, and the defect was allowed to fester basically uncontested, then the neighbor could make an argument (again-- michigan statute here) after 15 years for "prescriptive easement"- since it WAS allowed, then the then-seller's rights (now that's me as of last week) can REVOKE those privileges.   

If it is not obvious, such as for a mental health disability, you can ask for a copy of the prescribing medical professionals prescription/order and that is it.

But this safe harbor is an example and not prescriptive. 

Essentially, if you belong to an IPA, you goto the one stop shop where you can see your primary, your cardiologist, get your labs/xrays done, and get your prescriptions, instead of going to your doctor, then driving across town to see your cardiologist etc.   

. - does not indicate the ESA is a treatment (or prescription) for any condition - just a mental and behavioral health condition.- does not have a signature- does not have specific wording to comply with regulations (legal diagnosis, statement of treatment, ESA prescription, etc.)I believe CA passed a law (1/22) requiring the therapist to see the patient for 30 days prior to issuing an ESA recommendation and letter.

My thoughts are not prescriptive, but maybe something helped spark an idea.  

@Christine Krevalin - Any of my thoughts below are not meant to be prescriptive especially since we only know a small part of your story.

A title under a tax deed properly executed on or after July 1, 1996, at a valid and legal sale shall ripen by prescription after a period of four years from the recordation of that deed in the land records in the county in which said land is located.
