Preliminary Residential Agreement

PRA-1

A developing California purchase agreement designed from the transaction logic outward: rule, choice, language, branch, and authority.

Working draft • October 2026

From professional reasoning to contract language

  1. 1

    Rule

    The professional conclusion the agreement needs to implement.

  2. 2

    Choice

    The decision the parties are being asked to make.

  3. 3

    Language

    The operative words that allocate duty, timing, and consequence.

  4. 4

    Branch

    What happens when the facts or the parties' choices differ.

  5. 5

    Authority

    The source that gives the rule its weight—and the limits of that source.

Linked knowledge

The agreement and the Rulebook stay in conversation.

A Rulebook article can point to the exact PRA-1 section that implements it. A PRA-1 clause can point back to the reasoning, branches, and authority that explain why it exists.
