Reference to Original
Identify the original contract by title, date, and parties so the amendment cannot be misconstrued as a standalone agreement or apply to unrelated documents.
An Otrosi Agreement lets parties make a focused, narrowly scoped change quickly while preserving the original contract’s structure. It reduces drafting time, limits negotiation to the changed item, and documents mutual assent to the modification in a clear, discrete record.
Use the Otrosi when the change is narrow, all parties agree, and the amendment language can be unambiguous and self-contained.
An officer or manager with delegated authority signs on behalf of a company. Confirm the company’s internal delegation (board resolutions, power of attorney, or officer certifications) before execution to avoid later challenges to authority.
A named individual party signs for personal contracts or sole-proprietor arrangements. Include full legal name and contact information; if signing on behalf of an entity, include the title and a notation of capacity (for example, 'John Doe, CEO, for ABC, Inc.').
Identify the original contract by title, date, and parties so the amendment cannot be misconstrued as a standalone agreement or apply to unrelated documents.
Quote the exact provision(s) being replaced or state the insertion/deletion precisely; avoid vague terms such as 'modify as necessary.'
Specify the effective date of the change, which governs timing for performance, notice periods, and statute of limitations calculations.
Include printed name, title, capacity (individual or entity), signature line, and date for each party signing the Otrosi Agreement.
State the governing state law that will interpret the amendment if different from the original contract, or explicitly confirm the original governing law remains unchanged.
If needed, add a short clause confirming that except for the changes stated, the original agreement remains in full force and effect.
