Florida Probate Rule 5.120
“Administrator Ad Litem and Guardian Ad Litem”
What it means
Some interests in a probate case have nobody able to speak for them. Rule 5.120 supplies two stand-ins. An administrator ad litem represents the estate itself in a particular proceeding when there is no personal representative — or the one serving is adversely interested, including pressing their own claim against the estate.
A guardian ad litem represents a person who cannot represent themselves: an incapacitated person, an unborn or unascertained person, a minor or other person under a legal disability, a person with a developmental disability, or a person whose identity or address is unknown — whenever the court finds representation would otherwise be inadequate. The appointee serves without bond, files an oath, and defends as the court directs.
- An administrator ad litem stands in for the estate in one proceeding when no personal representative exists or the one serving has an adverse interest.
- A fiduciary enforcing their own debt or claim against the estate is a textbook trigger for an ad litem appointment.
- A guardian ad litem may be appointed at any point for incapacitated, unborn, unascertained, minor, or developmentally disabled persons — or anyone whose identity or address is unknown.
- The standard: representation of the interest would otherwise be inadequate. One guardian ad litem may cover several persons absent a conflict.
- The appointee serves without bond or notice, files an oath, and needs no service of process.
- Within 10 days of appointment, conformed copies of the petition and order go to the ward's guardians or the estate's beneficiaries.
How it plays out
We use Rule 5.120 most in missing-heir estates. After the search and the published notice, someone still must stand in for the heir nobody can find — the guardian ad litem is what lets the court's order bind that absent person under §731.303, so a distribution cannot be unwound years later. We also see administrators ad litem when a personal representative files a claim against the very estate they run. The appointment is quick and cheap relative to what it protects; orders touching an unrepresented interest are the ones that come back.
