Legal Definitions - rationabilibus divisis

The Latin phrase rationabilibus divisis refers to a historical legal concept concerning the establishment of clear and rightful boundaries between adjacent properties. Historically, it was associated with a specific legal action or "writ" in English common law, known as de rationabilibus divisis, which allowed landowners to seek a court's determination of disputed property lines.

In essence, this concept addresses situations where the exact division or demarcation between two parcels of land is uncertain or contested. The purpose was to achieve a "reasonable" or legally sound division, thereby resolving disputes and ensuring each landowner knew the precise extent of their property.

• Example 1: Rural Farmland Boundary

  Imagine two neighboring farmers, Mr. Henderson and Ms. Rodriguez, whose properties share a long border in a rural area. Over generations, a small stream that once served as a boundary has shifted its course slightly, and the old fence posts have rotted away. Mr. Henderson believes his property extends to one bank of the stream, while Ms. Rodriguez claims it extends to the other, impacting a significant portion of grazing land. A legal action akin to what rationabilibus divisis represented would allow a court to examine historical deeds, surveys, and local customs to establish a fair and legally recognized boundary, ensuring a "reasonable division" of the land between them.

  This example illustrates the term by showing a dispute over an unclear physical boundary between two large rural properties, where a court's intervention is needed to establish a just and reasonable division based on legal principles.

• Example 2: Urban Residential Property Line

  Consider two suburban homeowners, the Millers and the Chengs, whose properties are separated by a shared driveway and a small strip of garden. The original property plans from decades ago are vague regarding the exact dividing line for the garden and who is responsible for maintaining which part of the driveway. When the Millers decide to build a new fence, they discover their understanding of the boundary differs significantly from the Chengs'. A modern equivalent of the legal principles behind rationabilibus divisis would involve a court or mediator reviewing property records, conducting new surveys, and potentially considering long-standing usage patterns to determine the precise and "reasonable" dividing line, resolving their dispute over the exact extent of their urban plots.

  This example demonstrates the concept in an urban setting, highlighting how ambiguous historical records and differing interpretations of property lines can lead to disputes requiring a legal determination of a "reasonable division."

• Example 3: Historical Estate Division

  A historical estate, owned by the same family for centuries, is being divided among several heirs. One section of the estate borders a national park, and the original colonial-era land grants describe the boundary using natural features that have since changed or are no longer clearly identifiable, such as "to the great oak tree by the bend in the river." The heirs and the park service disagree on where the exact boundary lies, potentially affecting valuable timberland or conservation areas. A legal process reflecting the spirit of rationabilibus divisis would involve extensive research into historical documents, expert surveying, and judicial interpretation to establish a definitive and "reasonable" boundary that respects the original intent of the grants while accounting for modern realities, ensuring a clear division for all parties.

  This example illustrates the term by showing a complex boundary dispute involving very old, ambiguous descriptions and multiple parties, where a legal process is required to interpret historical intent and establish a "reasonable division" of land that is legally sound.
