Background
After Adahi Bustillos was deported to Mexico in 2024, his sister, Nalleli Bustillos Diaz, petitioned to become guardian of his estate. The petition alleged that the person managing Bustillos’s businesses had cut off his access to company information and bank accounts and transferred at least $400,000. The circuit court appointed Diaz permanent guardian in February 2025 and authorized her to pursue related civil claims.
Yannett Pinales and YP Construction, defendants in Diaz’s civil suit, sought to intervene in the guardianship case and vacate Diaz’s appointment. They argued that the guardianship lacked proof that Bustillos was incapacitated. Bustillos had, however, executed an affidavit requesting Diaz’s appointment, consented to the guardianship, and granted Diaz a durable general power of attorney authorizing her to prosecute legal proceedings on his behalf.
The Court’s Holding
The Arkansas Court of Appeals affirmed the denial of intervention. Even if the guardianship appointment were vacated for insufficient proof of incapacity, that result would not invalidate the civil suit Diaz had filed against Pinales.
Under Arkansas probate law, vacating an appointment does not undo acts previously performed or rights previously acquired in reliance on the order. Moreover, Bustillos’s durable power of attorney independently authorized Diaz to bring suit as his agent. Thus, Bustillos remained the real party in interest, and Pinales had no interest warranting intervention in the guardianship proceeding.
Key Takeaways
- A civil defendant cannot use intervention in a guardianship matter to defeat a related suit when vacating the appointment would not invalidate the suit.
- Failure to establish incapacity may make a guardianship order reversible, but it is not a jurisdictional defect.
- A durable power of attorney may independently support an agent’s authority to prosecute claims for the principal.
Why It Matters
The decision applies Arkansas precedent protecting actions taken under probate appointments even if the appointment is later vacated. Parties sued by an estate guardian cannot obtain dismissal indirectly by challenging the guardian’s appointment in probate court.
It also illustrates that the ward’s own grant of authority can defeat an intervention attempt: where a power of attorney authorizes litigation, a challenge to guardianship capacity may not alter who may pursue the claim.
