Pursuant to Florida guardianship law, who is an interested person? Can I participate in a Florida guardianship proceeding for my spouse, mom, dad, or aunt? Can I participate in a guardianship proceeding of just anyone? Who has the ability to go into a probate court West Palm Beach and have a say in someone’s guardianship proceeding? What do Palm Beach courts consider to be frivolous claims? Anyone who is involved in a guardianship matter in Florida should read St. Pete v. Osorio-Khor.
