Settling a Fountain Hills estate when an heir can't be found

A lot of people who settle in Fountain Hills came from somewhere else. They retired here from Chicago or Calgary or Minneapolis, sometimes after a second marriage, sometimes with children scattered across the country and a few relatives nobody has spoken to in twenty years.
When one of them dies, someone has to settle the estate. That person, usually called the personal representative, quickly finds out that Arizona law expects them to tell the heirs. And sometimes one of those heirs can't be found.
This piece explains where a private investigator fits in. It's general information. Probate has real legal duties attached, and you should work with a probate lawyer on anything beyond the simplest estate.
What the law asks of a personal representative
Under A.R.S. 14-3705, a personal representative has to give notice of their appointment within 30 days after being appointed. The notice goes by delivery or first-class mail to each heir and devisee whose address is reasonably available. It has to include the representative's name and address, say it's being sent to people who have or may have an interest in the estate, say whether a bond has been filed, and identify the court where the estate papers are filed.
"Reasonably available" is the phrase that matters here. If you don't have an heir's address, the question becomes what a reasonable effort to find it looks like. That's a judgment call your lawyer should help you make, and it's where a careful, documented search protects you.
Where the case is heard
Maricopa County Superior Court handles probate. Its probate and mental health department is listed at the East Court Building at 101 W. Jefferson Street and the Old Courthouse at 125 W. Washington Street, both in downtown Phoenix. From Fountain Hills, that's a drive west across Shea or down through Scottsdale and onto the freeway. Many filings can be handled without going in person, but it helps to know where your case lives.
Why heirs go missing
In probate work, a "missing heir" is rarely hiding. More often:
- they moved several times and nobody kept track
- they changed their name through marriage or divorce
- the family split long ago and contact stopped
- they live abroad
- they're a half-sibling, a child from an earlier marriage, or a relative the family barely knew about
- they've died, and their own children are now the heirs
That last one catches people out. Finding that an heir died ten years ago doesn't end the search. It often starts a new one.
How a private investigator approaches it
Heir location is mostly careful records work, often across several states. A licensed private investigator usually starts with what the family knows: full name, approximate age, last known city, names of parents or spouses, old addresses, a school, a former employer.
From there, they work through public records and lawful databases: address histories, court records including marriages and divorces where available, property records, obituaries and death records, and sometimes social media. They match details across sources, because the most common mistake in this work is finding the wrong person with the same name.
When they think they've found the heir, a good investigator confirms identity before anyone sends a letter. That might mean checking dates of birth, parents' names or past addresses against what the family knows. Then they report what they found and how, in writing.
That written report matters for you as the personal representative. If anyone later questions whether you tried hard enough, a dated record of the search is your answer.
Making contact
Who contacts the heir, and how, is something to agree on with your lawyer. Some families want the investigator to make a short, neutral first contact. Others want the lawyer to send the formal notice directly. Either way, the first message should be factual and calm. An estranged relative hearing about a death from a stranger deserves some care.
When an heir truly can't be found
Sometimes a search ends without an address. That happens. Your lawyer can tell you what the court expects next, which may include documenting the search in a filing. The investigator's report becomes part of that record.
What to send the private investigator
- the decedent's full name, date of birth and date of death
- the heir's full name, any former names, approximate age and last known location
- family relationships, as far as you know them
- copies of any old letters, cards or photos with names and places
- your lawyer's contact information
