    "description": "Inheritance disputes are perceived as the province of wealthy families with complicated trusts and scheming relatives — material for TV dramas, not ordinary households. Most people do not anticipate conflict over a parent's estate, and the topic is socially awkward to raise while the parent is alive. The widespread failure to create wills (only 24% of Americans had one in 2025, per Caring.com) means that intestate succession laws — which many heirs do not understand — govern the distribution for the vast majority of estates. The combination of emotional grief, opaque legal processes, and the sudden appearance of money in families unaccustomed to discussing finances creates a fertile environment for disputes that most people do not see coming.\n",

    "assumptions": "WARNING: This estimate is heavily constructed and no single published study directly measures the lifetime probability of inheritance loss for US adults. It is stitched from three heterogeneous sources: (1) a US consumer will-ownership survey (Caring.com), (2) UK probate court dispute-category data used as a US proxy (Dutton Gregory), and (3) US-focused probate cost ranges from an industry website (Protecting Wealth). Only about 1 in 10 wills are formally contested, and formal will contests represent a small fraction of all estates. The 35% figure attempts to include routine probate costs (3-8% of estate value) and informal family disagreements, not just formal litigation. However, \"meaningful loss\" (>5% of inheritance) is a constructed threshold with no empirical basis for its probability. The high intestacy rate (76%) creates conditions for disputes but does not directly translate to a dispute probability. The uncertainty range is extremely wide (20-50%) reflecting the absence of direct evidence. This entry is flagged as no_reliable_estimate because the 35% figure should not be treated as a measured prevalence.\n",

  "caveats": "The 35% estimate is the most heavily constructed figure in this dataset and should be treated with extreme caution. No single study tracks the lifetime probability of inheritance loss across the full US population. The figure stitches together three heterogeneous sources: a US consumer survey (will ownership), UK probate court data (dispute categories, used as a US proxy because US probate is fragmented across 50 state court systems with no centralized reporting), and US industry probate cost ranges. Only about 1 in 10 wills are formally contested, suggesting formal litigation risk is far lower than 35%. The higher estimate attempts to include routine probate costs (3-8% of estate value) and informal family disagreements, but these are qualitatively different from \"disputes\" in most people's understanding. \"Meaningful loss\" (>5% of inheritance value) is a constructed threshold — different definitions would yield different estimates. The entry also does not account for the fact that many Americans inherit very little: the Federal Reserve's 2022 SCF shows that the median inheritance received is approximately $69,000, and roughly 20% of American adults never inherit anything at all. This entry is flagged as no_reliable_estimate because the evidence base is too weak to support a specific probability claim.\n",
