Sue a Sibling for Inheritance in Florida | Trust Counsel<\/h1>\n

In some circumstances, a sibling may be sued over an inheritance in Florida. Whether a claim exists depends on the governing instrument, applicable Florida law and the facts of each case. A claim may challenge how a will or trust was made. It may also challenge how a sibling is handling estate or trust property. This page covers the main possibilities so you can see which questions matter. Trust Counsel, PL’s only office is in Coral Gables, Florida.<\/p>\n

Short answer: can you sue a sibling over an inheritance?<\/h2>\n

Can you sue a sibling for inheritance? Possibly, depending on the document and the facts. Two different questions often get mixed together. The first is a claim against a sibling personally, such as a challenge to a will or trust. The second is a claim about how a sibling is running an estate or trust as personal representative (often called an executor) or trustee.<\/p>\n

The answer also changes with the type of document. A will, a trust or no document at all each brings different rules. If a parent died without a valid will, Florida’s intestacy statute sets who inherits. Each of these paths is covered below. Start by identifying which document exists and which role each sibling holds.<\/p>\n\n

Which claims may a sibling bring against another sibling?<\/h2>\n

A sibling may bring a will contest, a trust contest, a fiduciary duty claim or a request for an accounting, depending on the facts. Each claim has its own rules and its own burden.<\/p>\n

A will may be challenged on certain grounds. Florida law says a will is void if its execution was procured by fraud, duress, mistake, or undue influence (Fla. Stat. \u00a7 732.5165<\/a>). A will contest also cannot start before the testator’s death (Fla. Stat. \u00a7 732.518<\/a>).<\/p>\n

Who carries the burden matters. In a will contest, the proponent must first establish formal execution and attestation. After that, the contestant has the burden of establishing the grounds for opposing probate (Fla. Stat. \u00a7 733.107<\/a>). In a trust contest, the contestant has the burden of establishing the grounds for invalidity (Fla. Stat. \u00a7 736.0207<\/a>).<\/p>\n

When a sibling serves as personal representative, the scope of that role depends on the governing instrument, applicable Florida law, and the facts of each case. Whether a court awards costs, including attorney’s fees, depends on the governing instrument, applicable Florida law, and the facts of each case. A claimant may need to qualify as an “interested person,” meaning someone who may reasonably be expected to be affected by the outcome (Fla. Stat. \u00a7 731.201<\/a>). Whether a particular sibling qualifies turns on the document and Florida law.<\/p>\n

The will or trust, the parent’s documented intent and the facts decide whether a sibling has a claim.<\/p>\n

A sibling may still question the document. Some possibilities include:<\/p>\n
